Neurologic Clinical Specialist (NCS) Examination — Questions and Answers

Question 1: Below which Berg Balance Scale (BBS) score is a community-dwelling older adult considered at increased fall risk?

Below 56
Below 20
Below 30
Below 45 (Correct answer)

Correct answer: Below 45

A BBS score below 45 out of 56 is the widely accepted threshold indicating increased fall risk in community-dwelling older adults.

Question 2: A TBI patient with spasticity and co-existing cognitive impairment is being considered for antispasticity medication. Which agent is most likely to worsen cognitive function?

Dantrolene sodium
Tizanidine
Oral baclofen (Correct answer)
Intrathecal baclofen

Correct answer: Oral baclofen

Oral baclofen crosses the blood-brain barrier and can significantly worsen cognition, sedation, and alertness in TBI patients, whereas intrathecal baclofen minimizes CNS side effects.

Question 3: When assessing a patient with suspected multiple sclerosis (MS), which of the following findings would be most indicative of an acute exacerbation?

Stable visual acuity without changes
Stable mood with no new cognitive symptoms
Persistent, low-grade fever
A sudden increase in spasticity (Correct answer)

Correct answer: A sudden increase in spasticity

An acute exacerbation, or relapse, in multiple sclerosis (MS) is characterized by new neurological symptoms or a worsening of existing symptoms lasting at least 24 hours, in the absence of fever or infection. A sudden increase in spasticity indicates new inflammation and demyelination in the central nervous system, which is the hallmark of an MS relapse. Other options like stable visual acuity or mood would suggest stability, not an acute exacerbation.

Question 4: When developing a treatment plan for a patient with Parkinson’s disease, which intervention is most likely to address gait disturbances effectively?

PNF (Proprioceptive Neuromuscular Facilitation) stretching
High-intensity interval training (HIIT)
Joint mobilization techniques
Dual-task training (Correct answer)

Correct answer: Dual-task training

Individuals with Parkinson's disease often experience significant gait disturbances, particularly when performing a cognitive task simultaneously (dual-tasking). Dual-task training specifically addresses this challenge by having patients practice walking while engaging in cognitive activities. This approach helps improve attentional allocation, automaticity of gait, and overall walking performance in real-world scenarios, where dual-tasking is common.

Question 5: What is task-specific training for gait?

Practicing the actual task of walking in various real-world conditions to improve functional mobility (Correct answer)
Only stretching
Only exercising on machines
Only strengthening exercises

Correct answer: Practicing the actual task of walking in various real-world conditions to improve functional mobility

Task-specific training applies motor learning principles: practicing the specific skill in varied, functional contexts.

Question 6: Myotonic dystrophy type 1 (DM1) is caused by:

CAG repeat expansion in the androgen receptor gene on chromosome X
CTG trinucleotide repeat expansion in the DMPK gene on chromosome 19q13 (Correct answer)
GAA repeat expansion in the frataxin gene on chromosome 9
CGG repeat expansion in the FMR1 gene causing RNA toxicity

Correct answer: CTG trinucleotide repeat expansion in the DMPK gene on chromosome 19q13

DM1 is caused by CTG expansion in the 3' UTR of the DMPK gene; expanded transcripts form nuclear foci that sequester RNA-binding proteins (MBNL), causing widespread splicing dysfunction and the multisystem phenotype.

Question 7: How does neurogenic shock differ from hypovolemic shock in acute spinal cord injury?

Neurogenic shock is caused by fluid loss; hypovolemic is caused by loss of sympathetic tone
Neurogenic shock features tachycardia and vasoconstriction; hypovolemic features bradycardia
Neurogenic shock features bradycardia and vasodilation; hypovolemic features tachycardia and vasoconstriction (Correct answer)
Both present identically and can only be differentiated with imaging

Correct answer: Neurogenic shock features bradycardia and vasodilation; hypovolemic features tachycardia and vasoconstriction

Neurogenic shock results from loss of sympathetic tone causing vasodilation and bradycardia, while hypovolemic shock causes compensatory tachycardia and vasoconstriction.

Question 8: What is myasthenia gravis?

A spinal cord disease
A genetic blood disorder
An autoimmune disorder where antibodies block acetylcholine receptors at the neuromuscular junction (Correct answer)
A brain tumor

Correct answer: An autoimmune disorder where antibodies block acetylcholine receptors at the neuromuscular junction

MG causes fluctuating muscle weakness that worsens with activity and improves with rest.

Question 9: During a neurological exam, a therapist finds that a patient has intact light touch but absent proprioception and vibration sense in the lower extremities. This pattern most suggests pathology in which tract?

Corticospinal tract
Anterior spinothalamic tract
Dorsal columns (posterior funiculus) (Correct answer)
Lateral spinothalamic tract

Correct answer: Dorsal columns (posterior funiculus)

Proprioception and vibration are carried in the dorsal columns; loss of these with intact pain/temperature indicates a dorsal column lesion.

Question 10: Which descending tract is primarily responsible for postural adjustments and gross limb movements, originating in the vestibular nuclei?

Tectospinal tract
Vestibulospinal tract (Correct answer)
Rubrospinal tract
Reticulospinal tract

Correct answer: Vestibulospinal tract

The vestibulospinal tract originates in the lateral vestibular nucleus (Deiters' nucleus) and facilitates extensor motor neurons to maintain upright posture and balance.

Question 11: When using the NDT/Bobath approach to facilitate knee extension during loading response in a patient with spastic hemiplegia, which handling strategy is most appropriate?

Apply progressive resistance to the knee extensors throughout full range to strengthen the muscle
Handle at the pelvis to facilitate weight shift onto the affected limb and normalize loading response (Correct answer)
Apply rapid stretch to the quadriceps muscle belly to trigger a facilitory stretch reflex
Use verbal cueing alone without manual facilitation to promote cortical motor control

Correct answer: Handle at the pelvis to facilitate weight shift onto the affected limb and normalize loading response

Pelvic facilitation and weight-shifting onto the affected side normalizes sensory input and activates appropriate knee extensor activity during loading response through postural alignment.

Question 12: The dorsal column-medial lemniscal pathway decussates at which level of the central nervous system?

Cervical spinal cord
Internal capsule
Spinal cord at the level of entry
Caudal medulla (nucleus gracilis/cuneatus) (Correct answer)

Correct answer: Caudal medulla (nucleus gracilis/cuneatus)

First-order neurons ascend ipsilaterally to synapse in the nucleus gracilis and cuneatus in the caudal medulla, where second-order axons then cross to form the medial lemniscus.

Question 13: Pompe disease (glycogen storage disease type II) causes neuromuscular weakness through:

Deficiency of acid alpha-glucosidase (GAA) causing lysosomal glycogen accumulation in muscle and motor neurons (Correct answer)
Mitochondrial Complex I deficiency causing ATP depletion in muscle
Dystrophin deficiency causing sarcolemmal fragility and fiber necrosis
Autoimmune attack on the neuromuscular junction mediated by anti-AChR antibodies

Correct answer: Deficiency of acid alpha-glucosidase (GAA) causing lysosomal glycogen accumulation in muscle and motor neurons

Pompe disease involves GAA enzyme deficiency; glycogen accumulates in lysosomes within muscle fibers and motor neurons, causing progressive proximal weakness, respiratory failure, and cardiomyopathy (in infantile form), treatable with enzyme replacement therapy.

Question 14: A patient post-stroke exhibits a strong elbow flexor synergy with minimal ability to isolate elbow extension. Which motor learning strategy should guide the initial intervention?

Strengthening of biceps to improve co-contraction stability at the elbow
Task-specific practice using movement patterns designed to break the synergy (Correct answer)
Passive range of motion to maintain joint mobility while awaiting spontaneous recovery
Repetitive isolated elbow extension against maximal resistance

Correct answer: Task-specific practice using movement patterns designed to break the synergy

Task-specific practice that incorporates synergy-breaking movement patterns leverages cortical plasticity and is the evidence-based approach for post-stroke upper extremity rehabilitation.

Question 15: A patient post-stroke demonstrates pusher syndrome. Which position is MOST appropriate when working on sitting balance?

Place the patient in a reclined position
Avoid upright positioning until pusher syndrome resolves
Promote weight-bearing through the affected side (Correct answer)
Promote weight-bearing through the non-affected side

Correct answer: Promote weight-bearing through the affected side

Promoting weight-bearing through the affected (hemi) side is the primary treatment strategy for pusher syndrome to correct the patient's distorted perception of body orientation.

Question 16: During aquatic therapy for a patient in the recovery phase of Guillain-Barré syndrome (3-/5 strength), which water temperature best supports rehabilitation?

Room temperature water (28–30°C) to maximize buoyancy and minimize weight-bearing stress
Thermoneutral water (33–36°C) to reduce muscle tone and minimize cardiovascular stress (Correct answer)
Cold water (< 25°C) to reduce metabolic demands and prevent overheating
Hot water (> 38°C) to maximize blood flow and promote muscle relaxation

Correct answer: Thermoneutral water (33–36°C) to reduce muscle tone and minimize cardiovascular stress

Thermoneutral water (33–36°C) minimizes cardiovascular demands and reduces muscle tone, making it most appropriate for patients with neuromuscular fatigue and potential autonomic instability in GBS.

Question 17: In diabetic peripheral neuropathy, the 'dying-back' axonopathy pattern is characterized by:

Proximal weakness before distal weakness
Distal symmetric sensory loss progressing proximally in a length-dependent pattern (Correct answer)
Selective loss of large-fiber vibration sense before small-fiber pain sense
Patchy multifocal sensory loss across multiple nerve territories

Correct answer: Distal symmetric sensory loss progressing proximally in a length-dependent pattern

Metabolic injury preferentially affects the longest axons first (length-dependent), causing distal-to-proximal 'stocking-glove' sensory loss as the axon dies back from its distal terminal.

Question 18: In the context of neurorehabilitation, which intervention is aimed at reducing spasticity and improving range of motion?

Bobath Technique
Neurodevelopmental Treatment (NDT)
Serial Casting (Correct answer)
Task-Specific Training

Correct answer: Serial Casting

Serial casting is an effective intervention for reducing spasticity and improving range of motion. It involves applying a series of casts to a limb, each holding the joint at its maximum available range of motion. Over time, this sustained, low-load stretch gradually lengthens shortened muscles and connective tissues, thereby decreasing spasticity and increasing flexibility, particularly in cases of contracture.

Question 19: In spinal muscular atrophy (SMA), SMN1 gene deletion leads to:

Progressive degeneration of alpha motor neurons in the anterior horn of the spinal cord (Correct answer)
Demyelination of peripheral motor nerve axons causing conduction slowing
Loss of sensory neurons in dorsal root ganglia with preserved motor function
Dysfunction of neuromuscular junction vesicle release causing fatigable weakness

Correct answer: Progressive degeneration of alpha motor neurons in the anterior horn of the spinal cord

SMN protein deficiency selectively causes degeneration of anterior horn alpha motor neurons; SMA is therefore a pure lower motor neuron disease with proximal > distal weakness, areflexia, and tongue fasciculations — sensory function is preserved.

Question 20: Which descending pain modulation pathway utilizes serotonin and norepinephrine as primary neurotransmitters?

Dorsal column-medial lemniscal pathway
Anterolateral system
Dorsolateral funiculus (PAG-RVM system) (Correct answer)
Spinothalamic tract

Correct answer: Dorsolateral funiculus (PAG-RVM system)

The PAG-RVM-dorsolateral funiculus system uses serotonin and norepinephrine to exert descending inhibitory control over dorsal horn neurons.

Question 21: 'Canal conversion' during BPPV canalith repositioning refers to:

Spontaneous disappearance of nystagmus mid-maneuver
Complete resolution of BPPV without residual symptoms
Canaliths migrating from one semicircular canal to another during the maneuver (Correct answer)
Conversion from peripheral to central BPPV etiology

Correct answer: Canaliths migrating from one semicircular canal to another during the maneuver

Canal conversion occurs when repositioning maneuvers inadvertently shift debris into a different semicircular canal (e.g., posterior to horizontal), requiring recognition of the changed nystagmus pattern and a different treatment approach.

Question 22: The corticospinal tract synapses most directly onto alpha motor neurons via interneurons in which spinal cord lamina?

Lamina IX (ventral horn motor columns) (Correct answer)
Lamina I (marginal zone)
Lamina VII (intermediate gray)
Laminae IV-VI (intermediate zone)

Correct answer: Lamina IX (ventral horn motor columns)

Corticospinal tract fibers primarily synapse directly or via interneurons onto alpha motor neurons in lamina IX of the anterior horn, though some also terminate in laminae IV–VIII.

Question 23: The Dix-Hallpike test is the gold standard for diagnosing BPPV affecting which canal?

Posterior semicircular canal (Correct answer)
Anterior semicircular canal
Cochlear duct
Horizontal semicircular canal

Correct answer: Posterior semicircular canal

The Dix-Hallpike maneuver positions the posterior semicircular canal in the plane of gravity, provoking characteristic upbeat-torsional nystagmus when canaliths are displaced into that canal.

Question 24: A patient with MS and significant Uhthoff's phenomenon is referred for balance and gait rehabilitation. Which modification is MOST appropriate?

Avoid all exercise since heat permanently worsens neurological symptoms
Restrict training to cognitive dual-task activities only to avoid physical exertion
Rapidly increase training intensity to build heat tolerance
Schedule sessions in a cool environment, use cooling vests, and monitor for symptom changes during exercise (Correct answer)

Correct answer: Schedule sessions in a cool environment, use cooling vests, and monitor for symptom changes during exercise

Uhthoff's phenomenon causes temporary, reversible worsening of MS symptoms with increased body temperature; cooling strategies (precooling, air-conditioned environment, cooling vest) enable safe participation in rehabilitation.

Question 25: Which cueing strategy has the strongest evidence for managing freezing of gait in Parkinson's disease?

Reducing ambient lighting to minimize visual distractions
Rhythmic auditory stimulation using a metronome (Correct answer)
Shortening step length to match the freezing pattern
Verbal commands to walk faster

Correct answer: Rhythmic auditory stimulation using a metronome

Rhythmic auditory stimulation provides an external temporal cue that bypasses the defective internal rhythm-generation mechanism in the basal ganglia to initiate and sustain gait.

Question 26: Chronic traumatic encephalopathy (CTE) is definitively diagnosed by:

Neuropathological examination at autopsy demonstrating perivascular p-tau accumulation (Correct answer)
Neuropsychological testing showing progressive decline over 10+ years
Characteristic findings on PET imaging with tau ligands during life
MRI showing medial temporal atrophy with white matter changes

Correct answer: Neuropathological examination at autopsy demonstrating perivascular p-tau accumulation

CTE can only be definitively diagnosed post-mortem by identifying perivascular accumulation of hyperphosphorylated tau (p-tau) at the depths of sulci on neuropathological examination.

Question 27: A patient with stable T10 complete paraplegia develops ascending sensory loss, new upper extremity weakness, and worsening spasticity several years after injury. The most likely diagnosis is:

Recurrent spinal cord compression from hardware failure
Recurrent autonomic dysreflexia episodes
Post-traumatic syringomyelia (Correct answer)
New pressure injury at the injury site

Correct answer: Post-traumatic syringomyelia

Post-traumatic syringomyelia is a fluid-filled cavity that expands within the cord causing ascending neurological deterioration years after a stable SCI.

Question 28: Ketamine's analgesic mechanism in chronic pain states primarily involves:

Sodium channel blockade at peripheral nociceptors
Mu-opioid receptor agonism
COX-1 and COX-2 inhibition
NMDA receptor antagonism reducing central sensitization (Correct answer)

Correct answer: NMDA receptor antagonism reducing central sensitization

Ketamine blocks NMDA receptors, interrupting the glutamate-driven central sensitization and wind-up that perpetuate chronic pain states.

Question 29: Which component of the neurological examination would best differentiate an upper motor neuron lesion from a lower motor neuron lesion?

Two-point discrimination threshold measurement
Testing vibration sense with a 128 Hz tuning fork
Assessment of deep tendon reflexes and muscle tone (Correct answer)
Assessing stereognosis with common objects

Correct answer: Assessment of deep tendon reflexes and muscle tone

UMN lesions produce hyperreflexia and spasticity, while LMN lesions cause hyporeflexia or areflexia with flaccidity, making DTRs and tone the key differentiating assessment.

Question 30: Which outcome measure is specifically designed to assess balance confidence in older adults with neurological conditions, using a 16-item scale?

Functional Reach Test
Dynamic Gait Index
Activities-specific Balance Confidence (ABC) Scale (Correct answer)
Berg Balance Scale

Correct answer: Activities-specific Balance Confidence (ABC) Scale

The ABC Scale measures self-reported confidence in performing 16 activities without losing balance, rated 0-100% per item.

Question 31: A patient with Friedrich's ataxia presents with progressive spinocerebellar degeneration and hypertrophic cardiomyopathy. In establishing physical therapy goals, the therapist must prioritize:

Intensive strengthening to prevent the inevitable decline
Aggressive aerobic training to maximally stress cardiovascular adaptation
Aquatic therapy without cardiac screening
Functional maintenance, fall prevention, and exercise within cardiac tolerance limits (Correct answer)

Correct answer: Functional maintenance, fall prevention, and exercise within cardiac tolerance limits

Friedreich's ataxia is progressive with life-limiting cardiomyopathy; goals should balance functional maintenance with cardiac precautions.

Question 32: Which brainstem structure contains the nucleus for cranial nerve VII and is responsible for facial motor control?

Midbrain
Pons (Correct answer)
Diencephalon
Medulla oblongata

Correct answer: Pons

The facial nerve (CN VII) motor nucleus is located in the pons, which also houses nuclei for CN V, VI, and VIII.

Question 33: The muscle spindle's Ia afferent fibers respond to which stimulus, and what reflex do they mediate?

Joint capsule compression; withdrawal reflex
Golgi tendon organ stretch; inverse myotatic reflex
Free nerve endings; nociceptive flexion reflex
Muscle belly stretch; monosynaptic stretch (myotatic) reflex (Correct answer)

Correct answer: Muscle belly stretch; monosynaptic stretch (myotatic) reflex

Ia afferents from the annulospiral endings of the muscle spindle detect muscle stretch and synapse directly on alpha motor neurons, mediating the monosynaptic stretch reflex (e.g., patellar tendon reflex).

Question 34: A patient with fibromyalgia has failed multiple pharmacological treatments. Which non-pharmacological intervention has the strongest evidence base for fibromyalgia?

Aerobic exercise (Correct answer)
Spinal cord stimulation
Transcranial magnetic stimulation (TMS)
Opioid rotation

Correct answer: Aerobic exercise

Graded aerobic exercise is supported by strong evidence and EULAR guidelines as a cornerstone treatment for fibromyalgia pain and fatigue.

Question 35: The ASIA standard key sensory point for the L3 dermatome is located at the:

Medial femoral condyle (Correct answer)
Lateral aspect of the popliteal fossa
Medial malleolus
Dorsum of the foot at the third metatarsal head

Correct answer: Medial femoral condyle

The ASIA standard sensory testing point for L3 is the medial femoral condyle.

Question 36: What is transcutaneous electrical nerve stimulation (TENS)?

A medication
A type of surgery
A non-invasive pain management technique using electrical currents through skin electrodes (Correct answer)
A brain scan

Correct answer: A non-invasive pain management technique using electrical currents through skin electrodes

TENS delivers low-voltage electrical currents to modulate pain signals through the gate control theory.

Question 37: A patient demonstrates increased spasticity and decreased function in their affected lower extremity. Botulinum toxin injection is most appropriately targeted to which muscle group to improve gait?

Gastrocnemius-soleus complex (Correct answer)
Tibialis anterior
Iliopsoas
Quadriceps femoris

Correct answer: Gastrocnemius-soleus complex

Spasticity in the gastrocnemius-soleus complex causes equinovarus deformity and impedes heel strike; botulinum toxin to this group is the most common lower extremity injection to improve gait.

Question 38: Which opioid receptor subtype is primarily responsible for supraspinal analgesia?

Nociceptin/orphanin FQ (NOP)
Delta (δ)
Kappa (κ)
Mu (μ) (Correct answer)

Correct answer: Mu (μ)

Mu opioid receptors mediate the primary supraspinal analgesic effects and are the main target of most clinical opioids.

Question 39: A patient with right MCA stroke demonstrates contralateral neglect. Which scanning strategy is MOST effective as an initial compensatory approach?

Prism adaptation therapy
Visual field expansion training
Anchoring to the left side of tasks (Correct answer)
Patching the unaffected eye

Correct answer: Anchoring to the left side of tasks

Anchoring techniques teach patients to start scanning from the neglected side to compensate for unilateral spatial neglect.

Question 40: What is the primary neurotransmitter released at the neuromuscular junction?

Glutamate
Acetylcholine (Correct answer)
Dopamine
Norepinephrine

Correct answer: Acetylcholine

Somatic motor neurons release acetylcholine at the neuromuscular junction, which binds nicotinic receptors on the motor end plate to trigger muscle contraction.

Question 41: Mental practice (motor imagery) combined with physical practice has evidence for post-stroke upper extremity recovery PRIMARILY because it activates which neural substrate?

Overlapping cortical motor networks used during actual movement (Correct answer)
Basal ganglia reward pathways
Cerebellum via internal forward models
Reticulospinal tracts for postural tone

Correct answer: Overlapping cortical motor networks used during actual movement

Mental practice activates overlapping cortical motor networks used during actual movement execution, enhancing neuroplasticity when combined with physical practice.

Question 42: What is the difference between nociceptive and neuropathic pain?

Nociceptive pain results from tissue damage; neuropathic pain results from nerve damage (Correct answer)
Nociceptive is more severe
Neuropathic always means cancer
They are the same

Correct answer: Nociceptive pain results from tissue damage; neuropathic pain results from nerve damage

Nociceptive pain has a clear tissue injury source, while neuropathic pain arises from nervous system dysfunction.

Question 43: A therapist is measuring the 6-Minute Walk Test (6MWT) in a patient with MS. The primary clinical decision this test informs is:

Diagnosing fatigue severity
Predicting fall risk in the community
Determining readiness for discontinuation of therapy
Establishing aerobic capacity and walking endurance for intervention planning (Correct answer)

Correct answer: Establishing aerobic capacity and walking endurance for intervention planning

The 6MWT measures submaximal aerobic capacity and functional walking endurance, which directly informs exercise prescription intensity and endurance goals.

Question 44: When training stair negotiation in a patient with right hemiplegia post-stroke, what is the standard instruction for ascending stairs?

Lead with the right (affected) leg going up to strengthen the hemiparetic limb
Use a sideways sidestepping pattern with the stronger leg always on the higher step
Alternate legs with whichever is stronger leading on each individual step
Lead with the left (unaffected) leg going up, bearing weight through it on the higher step (Correct answer)

Correct answer: Lead with the left (unaffected) leg going up, bearing weight through it on the higher step

The mnemonic 'up with the good, down with the bad' reflects that the unaffected leg leads ascending so it bears weight on the higher step, protecting the weaker limb.

Question 45: The hippocampus is critical for which type of memory formation?

Implicit habit learning
Declarative (explicit) episodic and semantic memory (Correct answer)
Priming effects
Procedural motor memory

Correct answer: Declarative (explicit) episodic and semantic memory

The hippocampus is essential for encoding and consolidating declarative (explicit) memories, including episodic (personal events) and semantic (factual) memory, while procedural memory relies on the cerebellum and basal ganglia.

Question 46: In multiple sclerosis (MS), which of the following is the primary pathophysiological process?

Cortical neuron apoptosis
Excessive dopamine release in the basal ganglia
Autoimmune destruction of peripheral nerves
Demyelination of the central nervous system (Correct answer)

Correct answer: Demyelination of the central nervous system

Multiple Sclerosis (MS) is an autoimmune disease characterized by the immune system attacking the myelin sheath, which insulates nerve fibers in the central nervous system (brain, spinal cord, and optic nerves). This demyelination disrupts the efficient transmission of nerve impulses, leading to a wide range of neurological symptoms. It is the primary pathophysiological process that defines MS.

Question 47: Which neuroplasticity principle is MOST directly exploited by task-specific training in stroke rehabilitation?

Cross-education
Diaschisis resolution
Use-dependent cortical reorganization (Correct answer)
Use it or lose it

Correct answer: Use-dependent cortical reorganization

Repetitive task-specific practice drives use-dependent cortical reorganization, expanding the cortical representation of trained movements.

Question 48: According to the ASIA Impairment Scale, an ASIA A classification indicates:

No sensory or motor function preserved in sacral segments S4-S5 (Correct answer)
Incomplete injury with only sensory function below NLI
Motor function preserved with more than half key muscles graded ≥3
Incomplete injury with normal sensory and motor function

Correct answer: No sensory or motor function preserved in sacral segments S4-S5

ASIA A is a complete injury with no motor or sensory function preserved in the sacral segments S4-S5.

Question 49: For a patient with a traumatic brain injury (TBI), which outcome measure is most appropriate for assessing cognitive and executive function?

Berg Balance Scale
Mini-Mental State Examination (MMSE) (Correct answer)
Rancho Los Amigos Scale
Functional Independence Measure (FIM)

Correct answer: Mini-Mental State Examination (MMSE)

The Mini-Mental State Examination (MMSE) is a widely used and validated screening tool for assessing global cognitive function, which is often impaired in traumatic brain injury (TBI). It evaluates various cognitive domains including orientation, attention, memory, language, and visuospatial skills. While not exhaustive for all executive functions, it provides a quick and standardized measure of overall cognitive status relevant to TBI recovery and monitoring.

Question 50: The LANSS (Leeds Assessment of Neuropathic Symptoms and Signs) score ≥ 12 indicates:

Severe fibromyalgia activity
Pain predominantly of neuropathic origin (Correct answer)
High risk for opioid misuse
Moderate nociceptive pain requiring opioids

Correct answer: Pain predominantly of neuropathic origin

A LANSS score ≥ 12 suggests that pain mechanisms are predominantly neuropathic, guiding selection of neuropathic pain-specific therapies.

Question 51: A Timed Up and Go (TUG) result greater than which value is most commonly used to identify fall risk in older adults?

12 seconds (Correct answer)
8 seconds
30 seconds
20 seconds

Correct answer: 12 seconds

A TUG time exceeding 12 seconds in older adults is the most commonly cited threshold associated with increased fall risk.

Question 52: Stiff Person Syndrome (SPS) is most commonly associated with which autoantibody?

Anti-VGCC antibody associated with LEMS and small cell lung cancer
Anti-GAD65 antibody targeting glutamic acid decarboxylase (Correct answer)
Anti-AChR antibody targeting nicotinic receptors at the NMJ
Anti-GM1 IgM antibody associated with multifocal motor neuropathy

Correct answer: Anti-GAD65 antibody targeting glutamic acid decarboxylase

Anti-GAD65 antibodies are found in approximately 80% of SPS patients; GAD is the enzyme synthesizing GABA, so its impairment causes disinhibition of spinal interneurons, producing progressive rigidity, painful spasms, and exaggerated startle.

Question 53: A patient with chronic stroke presents with learned non-use of the affected upper extremity. Which intervention is specifically designed to address this mechanism?

Functional electrical stimulation to the non-affected arm
Constraint-induced movement therapy (CIMT) (Correct answer)
Proprioceptive neuromuscular facilitation bilateral patterns
Mirror therapy targeting the unaffected limb

Correct answer: Constraint-induced movement therapy (CIMT)

CIMT directly targets learned non-use by constraining the non-affected arm and forcing massed practice with the affected limb.

Question 54: A patient with a complete T6 spinal cord injury is being evaluated for functional goals. The most realistic expected functional outcome is:

Community ambulation with bilateral KAFOs and forearm crutches
Independent ambulation with AFOs and no assistive device
Dependent for all transfers requiring maximum assist
Independent manual wheelchair mobility and independent bed mobility (Correct answer)

Correct answer: Independent manual wheelchair mobility and independent bed mobility

T6 complete SCI patients have intact upper extremity function and typically achieve independent manual wheelchair use and bed mobility.

Question 55: A patient with TBI cannot walk safely while performing a cognitive task. According to motor learning principles, what is the BEST initial approach?

Prescribe a walker permanently to reduce cognitive demands during ambulation
Practice dual tasks immediately to simulate real-world demands and force neural adaptation
Focus exclusively on cognitive rehabilitation until cognitive function normalizes
Master the primary motor task (walking) first, then systematically introduce cognitive challenges (Correct answer)

Correct answer: Master the primary motor task (walking) first, then systematically introduce cognitive challenges

Motor learning principles support establishing a stable, automatic single-task foundation before adding cognitive demands, particularly when the primary motor task is not yet automatic.

Question 56: A patient with early Parkinson's disease is referred for physical therapy. Which intervention approach has the highest level of evidence for slowing functional decline?

Aquatic therapy exclusively due to reduced fall risk
Passive ROM and massage to reduce rigidity
High-intensity exercise (e.g., treadmill training, cycling at vigorous effort) (Correct answer)
Low-intensity stretching and relaxation only

Correct answer: High-intensity exercise (e.g., treadmill training, cycling at vigorous effort)

High-intensity exercise has the strongest evidence for neuroprotective effects and functional preservation in early Parkinson's disease.

Question 57: What is the Glasgow Coma Scale?

A brain scan type
A scoring system assessing consciousness level through eye opening, verbal response, and motor response (Correct answer)
A surgical rating
A pain scale

Correct answer: A scoring system assessing consciousness level through eye opening, verbal response, and motor response

GCS scores range from 3-15, with scores below 8 indicating severe TBI.

Question 58: A patient with Huntington's disease has choreiform movements significantly affecting upper extremity function during ADLs. Which PT intervention strategy is most appropriate?

Progressive resistance training targeting the muscles producing choreiform movements
Speed training to improve coordination through faster movement repetition
EMG biofeedback to increase patient awareness of involuntary muscle activity
Weighted wrist cuffs and task simplification to reduce movement variability (Correct answer)

Correct answer: Weighted wrist cuffs and task simplification to reduce movement variability

Weighted cuffs dampen choreiform amplitude, and task simplification reduces attentional demands, together improving functional performance in Huntington's disease.

Question 59: CMT1A, the most common hereditary motor and sensory neuropathy, is caused by:

Mutation in GJB1 (connexin 32) gene on the X chromosome
Deletion of SMN1 gene on chromosome 5q
Point mutation in the MPZ (myelin protein zero) gene on chromosome 1
Duplication of the PMP22 gene on chromosome 17p11.2 (Correct answer)

Correct answer: Duplication of the PMP22 gene on chromosome 17p11.2

CMT1A results from a 1.5 Mb tandem duplication of chromosome 17p11.2 containing the PMP22 gene, causing overexpression of PMP22 and demyelinating neuropathy with markedly slow conduction velocities (<38 m/s).

Question 60: A patient with mild TBI presents 6 weeks post-injury with headaches, dizziness, cognitive slowing, and sleep disturbance. According to DSM-5, this presentation is best classified as:

Adjustment disorder with anxiety
Major neurocognitive disorder due to TBI
Mild neurocognitive disorder due to TBI (postconcussion syndrome) (Correct answer)
Somatic symptom disorder

Correct answer: Mild neurocognitive disorder due to TBI (postconcussion syndrome)

DSM-5 classifies persistent cognitive and somatic symptoms after mild TBI as mild neurocognitive disorder due to TBI when symptoms represent a decline from prior functioning.

Question 61: Watershed (borderzone) infarctions typically occur in which clinical scenario?

Severe systemic hypotension causing hypoperfusion at arterial boundary zones (Correct answer)
Vasospasm following subarachnoid hemorrhage
Venous sinus thrombosis causing cortical vein congestion
Cardioembolic occlusion of the middle cerebral artery

Correct answer: Severe systemic hypotension causing hypoperfusion at arterial boundary zones

Watershed zones at the periphery of major arterial territories receive the least perfusion pressure and are first to infarct when systemic blood pressure drops precipitously.

Question 62: Essential tremor is pathophysiologically distinct from Parkinson's rest tremor in that essential tremor is predominantly:

A 6–12 Hz action/postural tremor generated by abnormal oscillations in olivocerebellar circuits (Correct answer)
Associated with cogwheel rigidity and bradykinesia
A 4–6 Hz tremor present at rest, suppressed by action
Caused by dopamine depletion in the nigrostriatal pathway

Correct answer: A 6–12 Hz action/postural tremor generated by abnormal oscillations in olivocerebellar circuits

Essential tremor is an action/postural tremor at 6–12 Hz thought to arise from rhythmic oscillations in the inferior olive–cerebellum–thalamus loop, distinct from the dopamine-deficient, rest-dominant 4–6 Hz Parkinsonian tremor.

Question 63: A neurologic PT is treating a patient with progressive MS. Despite consistent therapy, function continues to decline. The most appropriate clinical decision is to:

Refer only to palliative care and end therapy
Discontinue therapy as the patient is not improving
Shift goals toward maintenance, adaptive strategies, and quality of life (Correct answer)
Increase session frequency to counteract the decline

Correct answer: Shift goals toward maintenance, adaptive strategies, and quality of life

When disease progression overrides functional gains, evidence supports shifting to maintenance and compensatory strategy goals to preserve function and quality of life.

Question 64: Which intervention is considered when spinal cord stimulation (SCS) is indicated for failed back surgery syndrome?

Intrathecal baclofen pump
Electrode placement at cervical C2 level
Electrode placement covering the thoracic cord at T8-T10 (Correct answer)
Stereotactic radiosurgery

Correct answer: Electrode placement covering the thoracic cord at T8-T10

For failed back surgery syndrome with leg pain, SCS electrodes are typically placed at T8-T10 to cover the lower extremity dermatomes.

Question 65: Which finding would most suggest a paraneoplastic etiology rather than classic ALS in a patient with progressive motor neuron disease?

Bulbar involvement with dysarthria and dysphagia early in the disease course
Presence of fasciculations on EMG in multiple limb regions
Rapid progression over weeks concurrent with known lymphoma and positive anti-Hu antibodies (Correct answer)
Combined upper and lower motor neuron signs on neurological examination

Correct answer: Rapid progression over weeks concurrent with known lymphoma and positive anti-Hu antibodies

Paraneoplastic motor neuron disease should be suspected when rapid progression is accompanied by a known malignancy (especially SCLC or lymphoma) or paraneoplastic antibodies (anti-Hu, anti-Amphiphysin); classic ALS features like fasciculations, UMN+LMN signs, and bulbar involvement can appear in both.

Question 66: A patient with refractory chronic migraine is being considered for occipital nerve stimulation (ONS). What is the theoretical basis for its analgesic effect?

Suppression of cortical spreading depression at the occipital cortex
Direct stimulation of the trigeminal nucleus caudalis via convergent pathways (Correct answer)
Activation of the hypothalamic pain modulation center
Blockade of C2 afferents entering the cervical cord

Correct answer: Direct stimulation of the trigeminal nucleus caudalis via convergent pathways

ONS modulates the trigeminocervical complex where occipital afferents converge with trigeminal pain signals, reducing migraine pain through neuromodulation.

Question 67: During gait analysis of a patient with Parkinson's disease, you note festination and freezing episodes. Which evidence-based cueing strategy should be prioritized?

Reducing walking speed to prevent falls
Bilateral arm constraint to focus attention on legs
External rhythmic auditory cueing (e.g., metronome) (Correct answer)
Verbal counting cadence without environmental cues

Correct answer: External rhythmic auditory cueing (e.g., metronome)

Rhythmic auditory stimulation (RAS) bypasses deficient internal rhythm generation in PD and has strong evidence for reducing freezing and festination.

Question 68: A patient with a right parietal lobe lesion shows difficulty dressing themselves despite intact motor and sensory function. The most accurate clinical decision framework identifies this as:

Motor apraxia requiring strengthening
Anosognosia requiring behavioral modification only
Wernicke's aphasia requiring language therapy
Constructional apraxia or dressing apraxia requiring perceptual-motor strategy training (Correct answer)

Correct answer: Constructional apraxia or dressing apraxia requiring perceptual-motor strategy training

Dressing difficulty with intact motor and sensory function after parietal lesion indicates dressing apraxia, addressed through perceptual-motor strategy training.

Question 69: A 30-year-old patient with moderate TBI develops elevated serum sodium (160 mEq/L) with large urine output and low urine osmolality 5 days post-injury. The most likely diagnosis is:

Central diabetes insipidus (CDI) (Correct answer)
Cerebral salt wasting (CSW)
Syndrome of inappropriate antidiuretic hormone (SIADH)
Hyperaldosteronism

Correct answer: Central diabetes insipidus (CDI)

Central diabetes insipidus results from hypothalamic/pituitary damage causing ADH deficiency, leading to hypernatremia, polyuria, and dilute urine after TBI.

Question 70: Which of the following methods is most appropriate for managing post-stroke hemiparesis and improving hand function?

Kinesiotaping
Deep Brain Stimulation
Neuromuscular Reeducation
Constraint-Induced Movement Therapy (CIMT) (Correct answer)

Correct answer: Constraint-Induced Movement Therapy (CIMT)

Constraint-Induced Movement Therapy (CIMT) is a highly effective intervention for improving upper extremity function, particularly hand function, in patients with post-stroke hemiparesis. CIMT works by restraining the unaffected limb, forcing the patient to use their weaker, affected limb for intensive, repetitive, and task-specific training. This approach promotes neuroplasticity and helps "rewire" the brain to regain motor control in the affected hand.

Question 71: In amyotrophic lateral sclerosis (ALS), EMG characteristically demonstrates which combination of findings?

Fibrillations, fasciculations, and large polyphasic motor unit action potentials (Correct answer)
Absent sensory nerve action potentials with normal motor studies
Conduction block at multiple sites with normal motor unit morphology
Myopathic potentials with early recruitment and small MUAPs

Correct answer: Fibrillations, fasciculations, and large polyphasic motor unit action potentials

ALS shows both acute denervation (fibrillations, positive sharp waves, fasciculations) and chronic reinnervation (large polyphasic MUAPs) due to ongoing motor neuron loss with surviving motor units compensating.

Question 72: When assessing spasticity using the Modified Ashworth Scale, a grade of 2 indicates:

Slight increase in tone with a catch and release
More marked increase in tone through most of the ROM but limb moves easily (Correct answer)
Considerable increase in tone with passive movement difficult
No increase in muscle tone

Correct answer: More marked increase in tone through most of the ROM but limb moves easily

Modified Ashworth grade 2 indicates a more marked increase in muscle tone through most of the ROM, but the limb is still moved easily.

Question 73: Current clinical guidelines recommend that wheelchair users perform pressure relief how frequently to prevent pressure injuries?

Every 30 minutes for at least 30–60 seconds (Correct answer)
Every 2 hours consistent with standard bed repositioning schedules
Once per hour for 5 minutes
Every 4 hours during daytime hours

Correct answer: Every 30 minutes for at least 30–60 seconds

Pressure relief should be performed every 30 minutes for at least 30–60 seconds to prevent ischemic injury in insensate skin.

Question 74: Which clinical measure has the STRONGEST evidence for predicting future fall risk in community-dwelling older adults with neurological conditions?

Berg Balance Scale score below 45
Mini-BESTest with a cutoff score below 20
Functional Reach Test less than 10 inches
Timed Up and Go (TUG) test taking longer than 12 seconds (Correct answer)

Correct answer: Timed Up and Go (TUG) test taking longer than 12 seconds

A TUG time greater than 12 seconds has robust validation data across neurological and older adult populations as a threshold predictive of increased fall risk in community settings.

Question 75: A neurologist's note documents 'hyperreflexia with sustained clonus at the ankle.' Which clinical implication is MOST relevant to the PT's plan of care?

Lower motor neuron lesion requiring neuromuscular electrical stimulation
Upper motor neuron lesion pattern requiring spasticity management strategies (Correct answer)
Peripheral neuropathy requiring desensitization protocol
Cerebellar dysfunction requiring balance retraining only

Correct answer: Upper motor neuron lesion pattern requiring spasticity management strategies

Hyperreflexia and sustained clonus are hallmark signs of an upper motor neuron lesion, indicating spasticity that must be addressed through positioning, stretching, and spasticity management in the plan of care.

Question 76: Gaze stabilization and habituation exercises (Cawthorne-Cooksey) are MOST effective for which type of vestibular disorder?

Unilateral peripheral vestibular hypofunction (e.g., vestibular neuritis) (Correct answer)
Benign paroxysmal positional vertigo (BPPV)
Bilateral vestibular hypofunction
Central vestibular dysfunction from brainstem stroke

Correct answer: Unilateral peripheral vestibular hypofunction (e.g., vestibular neuritis)

These exercises promote central compensation for the asymmetric vestibular signal in unilateral peripheral hypofunction; they are less effective for bilateral loss (insufficient remaining signal) or BPPV (a mechanical rather than adaptive problem).

Question 77: A patient with Parkinson's disease experiences significant motor 'off' periods in the morning before medications take effect. When should the physical therapist schedule the most demanding exercise sessions?

During 'off' periods to challenge motor adaptation under worst-case conditions
During medication 'on' periods when dopaminergic drive maximizes motor performance (Correct answer)
In the late evening after all daily medication doses have been administered
At a fixed time each day regardless of medication timing for behavioral consistency

Correct answer: During medication 'on' periods when dopaminergic drive maximizes motor performance

Exercise during medication 'on' periods maximizes motor performance, enables higher practice intensity, and reduces fall risk during challenging tasks.

Question 78: Functional electrical stimulation (FES) cycling is used in SCI rehabilitation primarily to achieve:

Permanent restoration of voluntary motor control by retraining neural pathways
Cardiovascular conditioning and reduction of disuse atrophy in paralyzed limbs (Correct answer)
Prevention of heterotopic ossification through passive joint cycling
Community ambulation substituting for bracing in complete paraplegia

Correct answer: Cardiovascular conditioning and reduction of disuse atrophy in paralyzed limbs

FES cycling provides cardiovascular fitness and reduces disuse atrophy in paralyzed limbs, though it does not restore voluntary motor control.

Question 79: Diffuse axonal injury (DAI) after TBI is best visualized on which MRI sequence?

Susceptibility-weighted imaging (SWI) (Correct answer)
T1-weighted imaging
FLAIR (Fluid-Attenuated Inversion Recovery)
Diffusion tensor imaging (DTI)

Correct answer: Susceptibility-weighted imaging (SWI)

SWI is the most sensitive conventional MRI sequence for detecting microhemorrhages associated with DAI due to its sensitivity to blood products and iron.

Question 80: Habituation exercises for vestibular dysfunction are MOST appropriate for patients with:

Acute vestibular neuritis within the first 48 hours of onset
Chronic motion sensitivity from stable unilateral vestibular hypofunction (Correct answer)
Active BPPV requiring canalith repositioning
Complete bilateral vestibular loss

Correct answer: Chronic motion sensitivity from stable unilateral vestibular hypofunction

Habituation exercises, which use repeated exposure to symptom-provoking movements to reduce sensitivity, are most effective in patients with stable peripheral vestibular lesions causing motion-triggered symptoms.

Question 81: The ischemic penumbra surrounding a core infarct is clinically significant because it represents tissue that is:

Functionally impaired but potentially salvageable with timely reperfusion (Correct answer)
Already undergoing apoptosis due to glutamate excitotoxicity
Irreversibly infarcted and cannot be salvaged
Protected by collateral circulation and will recover spontaneously

Correct answer: Functionally impaired but potentially salvageable with timely reperfusion

The penumbra has reduced blood flow (20–50 mL/100g/min) sufficient to maintain membrane integrity temporarily but not function; reperfusion within the therapeutic window can rescue this tissue.

Question 82: According to ACRM guidelines, which intervention has Level I evidence for improving functional outcomes during acute TBI rehabilitation?

Transcranial magnetic stimulation
Pharmacological neuroprotection with progesterone
Hyperbaric oxygen therapy
Early intensive inpatient rehabilitation (Correct answer)

Correct answer: Early intensive inpatient rehabilitation

Early initiation of intensive, interdisciplinary inpatient rehabilitation is supported by Level I evidence for improving functional outcomes after moderate-to-severe TBI.

Question 83: Which diagnostic tool is most useful for differentiating between a primary brain tumor and a metastatic brain lesion?

Magnetic Resonance Imaging (MRI) with contrast (Correct answer)
Computed Tomography (CT) scan
Positron Emission Tomography (PET) scan
Electroencephalogram (EEG)

Correct answer: Magnetic Resonance Imaging (MRI) with contrast

Magnetic Resonance Imaging (MRI) with contrast is the most useful diagnostic tool for differentiating between a primary brain tumor and a metastatic brain lesion. MRI provides superior soft tissue resolution compared to CT scans, allowing for detailed visualization of lesion characteristics, surrounding edema, and patterns of enhancement with contrast. These features, along with location and multiplicity, often help distinguish between the two types of tumors.

Question 84: In the spinal cord, the spinothalamic tract carries pain and temperature information and crosses at which level?

At the brainstem
At the thalamus
Within 1-2 spinal segments of entry via the anterior commissure (Correct answer)
At the postcentral gyrus

Correct answer: Within 1-2 spinal segments of entry via the anterior commissure

Second-order spinothalamic neurons cross the midline through the anterior white commissure within 1-2 segments of their dorsal horn synapse before ascending contralaterally.

Question 85: What is the Berg Balance Scale?

A 14-item clinical assessment measuring static and dynamic balance abilities (Correct answer)
A type of exercise equipment
A weight measurement tool
A musical instrument

Correct answer: A 14-item clinical assessment measuring static and dynamic balance abilities

The Berg Balance Scale scores from 0-56, with higher scores indicating better balance and lower fall risk.

Question 86: When interpreting an MRI report indicating a T2 hyperintense lesion in the posterior limb of the internal capsule, a neurologic PT should anticipate which primary functional deficit?

Expressive aphasia
Contralateral spastic hemiplegia (Correct answer)
Bilateral lower extremity weakness
Ipsilateral limb ataxia

Correct answer: Contralateral spastic hemiplegia

The posterior limb of the internal capsule carries the corticospinal tract, and a lesion there produces contralateral spastic hemiplegia.

Question 87: A patient with Parkinson's disease demonstrates freezing of gait when approaching a doorway. Which cueing strategy is MOST evidence-based for immediate gait initiation?

Visual transverse line cues on the floor (Correct answer)
Rhythmic auditory stimulation with a metronome
Tactile cues on the hip
Verbal counting cadence

Correct answer: Visual transverse line cues on the floor

Transverse visual floor cues (lines or stripes) are the most evidence-supported strategy specifically for triggering gait initiation and overcoming freezing episodes at thresholds.

Question 88: A patient with C6 ASIA B SCI is being educated on skin integrity. What is the MINIMUM recommended frequency for pressure relief when seated in a wheelchair?

Every 2 hours
Every 15–30 minutes (Correct answer)
Every 60 minutes
Every 30 minutes

Correct answer: Every 15–30 minutes

Current SCI clinical guidelines recommend weight shifts or pressure relief maneuvers every 15–30 minutes while seated to prevent ischemic tissue damage.

Question 89: A patient post-stroke presents with left-sided neglect and poor safety awareness during transfers. Which immediate intervention priority best reflects evidence-based clinical decision-making?

Discharge to home with caregiver education only
Address neglect with visual scanning training before progressing mobility (Correct answer)
Begin constraint-induced movement therapy to the left UE
Focus solely on strengthening the affected limb

Correct answer: Address neglect with visual scanning training before progressing mobility

Neglect and poor safety awareness must be addressed before advancing mobility tasks to prevent falls and injury.

Question 90: A patient with Guillain-Barré syndrome has an FVC of 18 mL/kg. What is the most appropriate clinical decision?

Initiate incentive spirometry and discharge planning
Continue ambulation training as tolerated
Proceed with aggressive respiratory muscle strengthening exercises
Notify the physician immediately due to impending respiratory failure risk (Correct answer)

Correct answer: Notify the physician immediately due to impending respiratory failure risk

An FVC below 20 mL/kg in GBS indicates critical risk for respiratory failure and requires urgent physician notification.

Question 91: Post-traumatic seizures (PTS) occurring within the first 7 days after TBI are classified as:

Reflex epilepsy
Early PTS (Correct answer)
Remote symptomatic epilepsy
Late PTS

Correct answer: Early PTS

PTS within the first 7 days are classified as early PTS; those occurring after 7 days are late PTS, which carry a higher risk for developing epilepsy.

Question 92: What is amyotrophic lateral sclerosis (ALS)?

An infection of the nerves
A progressive disease destroying motor neurons, causing muscle weakness and eventually paralysis (Correct answer)
A type of brain tumor
A curable nerve condition

Correct answer: A progressive disease destroying motor neurons, causing muscle weakness and eventually paralysis

ALS progressively destroys upper and lower motor neurons, leading to loss of voluntary muscle control.

Question 93: A patient with vestibular neuritis presents with spontaneous nystagmus beating right and falls toward the left. The most appropriate initial clinical decision is:

Refer for audiological evaluation before initiating any therapy
Immediately perform canalith repositioning maneuver
Prescribe vestibular suppressants as the primary intervention
Begin gaze stabilization exercises and adaptation training (Correct answer)

Correct answer: Begin gaze stabilization exercises and adaptation training

Vestibular neuritis involves a unilateral peripheral hypofunction best treated with gaze stabilization and habituation exercises to promote central compensation.

Question 94: In complex regional pain syndrome (CRPS Type I), the mechanism underlying allodynia and vasomotor changes most likely involves:

Complete peripheral nerve transection with failed regeneration
Arteriovenous fistula formation causing ischemia of the affected limb
Maladaptive central sensitization combined with peripheral sympathetic-sensory coupling and neurogenic inflammation (Correct answer)
Autoimmune antibody destruction of small-fiber sensory neurons

Correct answer: Maladaptive central sensitization combined with peripheral sympathetic-sensory coupling and neurogenic inflammation

CRPS involves central sensitization in the spinal cord and brain, plus aberrant sympathetic-afferent coupling at the periphery and ongoing neurogenic inflammation (SP, CGRP release), producing the characteristic allodynia, skin changes, and edema.

Question 95: A patient with a dense right hemispheric stroke reports feeling no disability and refuses therapy. The therapist recognizes this as anosognosia and should:

Document the deficit, engage family in education, and use motivational strategies while addressing safety (Correct answer)
Refer to psychiatry and suspend all physical therapy
Provide only written handouts since verbal education is ineffective
Respect patient autonomy and discontinue therapy immediately

Correct answer: Document the deficit, engage family in education, and use motivational strategies while addressing safety

Anosognosia requires family education, motivational approaches, and safety management while maintaining therapeutic engagement despite lack of insight.

Question 96: According to current evidence-based guidelines, which DVT prophylaxis regimen is recommended in acute SCI?

Warfarin with target INR 2.0–3.0 started immediately after injury
Aspirin 325 mg daily initiated on admission
Clopidogrel 75 mg daily as monotherapy
Low molecular weight heparin (LMWH) combined with mechanical compression devices (Correct answer)

Correct answer: Low molecular weight heparin (LMWH) combined with mechanical compression devices

Low molecular weight heparin combined with mechanical compression devices is the recommended DVT prophylaxis regimen in acute SCI due to very high thrombotic risk.

Question 97: A patient with normal pressure hydrocephalus (NPH) presents with the classic triad. Which of the following best represents the appropriate physical therapy clinical decision?

Initiate aquatic therapy as the first-line intervention
Refer to neurosurgery for shunting evaluation while managing safety and fall risk (Correct answer)
Aggressive balance retraining before neurosurgical referral
Focus exclusively on cognitive rehabilitation as it is the primary deficit

Correct answer: Refer to neurosurgery for shunting evaluation while managing safety and fall risk

NPH's triad (gait, cognition, incontinence) is potentially reversible with VP shunting, so early surgical referral combined with fall risk management is the priority.

Question 98: A patient with spinocerebellar ataxia shows poor balance equally with eyes open and closed on all surface types. How does this pattern differ from peripheral vestibular dysfunction?

There is no clinical difference between the two conditions on standardized testing
Cerebellar ataxia impairs balance in all sensory conditions; vestibular dysfunction shows specific deterioration when visual and somatosensory cues are disrupted (Correct answer)
Vestibular dysfunction does not worsen with eye closure
Cerebellar ataxia is surface-independent; vestibular dysfunction is surface-dependent only

Correct answer: Cerebellar ataxia impairs balance in all sensory conditions; vestibular dysfunction shows specific deterioration when visual and somatosensory cues are disrupted

Cerebellar ataxia impairs movement coordination regardless of sensory availability, causing deficits across all SOT conditions; peripheral vestibular loss specifically worsens performance in conditions 5 and 6 when only vestibular input is available.

Question 99: What are the levels of SCI and their functional implications?

All injuries are the same
Lumbar injuries affect arms
Cervical injuries affect arms and legs (tetraplegia); thoracic/lumbar injuries affect legs (paraplegia) (Correct answer)
Only cervical injuries cause paralysis

Correct answer: Cervical injuries affect arms and legs (tetraplegia); thoracic/lumbar injuries affect legs (paraplegia)

The level of injury determines which body functions are affected below that point.

Question 100: What are the major divisions of the nervous system?

Only the brain
Only nerves
Central nervous system (brain and spinal cord) and peripheral nervous system (Correct answer)
Only the spinal cord

Correct answer: Central nervous system (brain and spinal cord) and peripheral nervous system

The CNS processes information centrally while the PNS connects it to the rest of the body.

Question 101: Body-weight-supported treadmill training (BWSTT) for gait rehabilitation after stroke primarily works by facilitating which mechanism?

Reducing cardiovascular demand
Strengthening hip flexors through loaded stepping
Improving cerebellar coordination via visual feedback
Activating central pattern generators in the lumbar spinal cord (Correct answer)

Correct answer: Activating central pattern generators in the lumbar spinal cord

BWSTT unloads body weight to allow repetitive stepping, activating central pattern generators (CPGs) in the lumbar spinal cord to retrain locomotor patterns.

Question 102: A therapist uses the Fugl-Meyer Assessment to guide intervention for a patient 3 weeks post-ischemic stroke. This tool primarily informs decisions about which domain?

Community participation and vocational return
Cardiopulmonary endurance capacity
Degree of motor recovery and synergy pattern stage (Correct answer)
Cognitive and perceptual function

Correct answer: Degree of motor recovery and synergy pattern stage

The Fugl-Meyer Assessment measures motor recovery across the Brunnstrom stages of synergy, guiding movement-based intervention decisions.

Question 103: Central cord syndrome following hyperextension cervical injury characteristically spares which function?

Pain and temperature sensation below the lesion
Lower extremity motor function (Correct answer)
Upper extremity motor function
Bladder control

Correct answer: Lower extremity motor function

The corticospinal tract is somatotopically organized with cervical fibers medially and sacral fibers laterally; central hemorrhage/edema damages medial fibers first, sparing leg function more than arm function.

Question 104: Which finding MOST strongly suggests a central rather than peripheral vestibular etiology in a patient presenting with acute vertigo?

Normal head impulse test with spontaneous nystagmus present (Correct answer)
Positive Dix-Hallpike test with upbeat-torsional nystagmus
Nystagmus that is suppressed by visual fixation
Unilateral hearing loss with vertigo onset

Correct answer: Normal head impulse test with spontaneous nystagmus present

A normal head impulse test in the setting of acute spontaneous nystagmus (HINTS examination) strongly suggests central pathology, as peripheral lesions causing spontaneous nystagmus typically also impair the VOR, producing a positive head impulse test.

Question 105: Which pharmacological agent is most commonly used to manage agitation in the acute TBI rehabilitation setting due to its favorable side-effect profile?

Amantadine
Haloperidol
Lorazepam
Propranolol (Correct answer)

Correct answer: Propranolol

Propranolol (a beta-blocker) is preferred for agitation post-TBI because it reduces autonomic surges without the sedation or seizure-threshold-lowering effects of antipsychotics or benzodiazepines.

Question 106: A patient with left hemisphere stroke is MOST likely to exhibit which behavioral characteristic during rehabilitation?

Impulsivity and poor safety awareness
Depression, anxiety, and cautious behavior (Correct answer)
Spatial disorientation in familiar environments
Anosognosia for hemiplegia

Correct answer: Depression, anxiety, and cautious behavior

Left hemisphere stroke is more commonly associated with depression, anxiety, and overly cautious or catastrophic behavioral responses compared to right hemisphere stroke.

Question 107: Heterotopic ossification (HO) in individuals with SCI most commonly affects which joint?

Knee
Shoulder
Hip (Correct answer)
Ankle

Correct answer: Hip

Heterotopic ossification most commonly develops around the hip in individuals with SCI, causing pain, ROM restriction, and potential ankylosis.

Question 108: Which gait deviation is most characteristic of a patient with bilateral spastic lower extremity involvement from cerebral palsy?

Steppage gait
Antalgic gait
Scissor gait (Correct answer)
Trendelenburg gait

Correct answer: Scissor gait

Scissor gait results from bilateral adductor spasticity causing the legs to cross midline during swing phase.

Question 109: A patient with cervical myelopathy reports progressive gait instability and hand clumsiness but no radicular pain. Which examination finding would most strongly support a surgical referral decision?

Hyperreflexia, Hoffman's sign, and gait ataxia (Correct answer)
Positive Phalen's test bilaterally
Cervical range of motion less than 50% of normal
Positive spurling's test with dermatomal paresthesia

Correct answer: Hyperreflexia, Hoffman's sign, and gait ataxia

Upper motor neuron signs (hyperreflexia, Hoffman's sign) combined with gait ataxia indicate cord compression requiring urgent surgical evaluation.

Question 110: Post-traumatic amnesia (PTA) duration is most useful for predicting which outcome after moderate-to-severe TBI?

Severity of spasticity
Likelihood of returning to work
Long-term functional recovery (Correct answer)
Risk of post-traumatic seizures

Correct answer: Long-term functional recovery

PTA duration is one of the strongest predictors of long-term functional outcome; PTA >4 weeks is associated with significantly poorer recovery.

Question 111: Cerebellar ataxia produces which characteristic gait pattern?

Circumducting gait with ipsilateral arm posturing
Narrow-based, shuffling steps with reduced arm swing
Wide-based, staggering gait with irregular step lengths and lateral instability (Correct answer)
High-steppage gait with excessive hip flexion

Correct answer: Wide-based, staggering gait with irregular step lengths and lateral instability

Cerebellar ataxia causes a wide-based, staggering gait with variable step lengths due to impaired coordination and timing, resembling the appearance of intoxication.

Question 112: A patient 6 months post-right MCA stroke shows left UE spasticity (MAS 2) limiting hand opening for grasp. Which intervention decision is most evidence-based?

Refer for botulinum toxin injection and combine with task-specific training (Correct answer)
Avoid all passive stretching due to spasticity concerns
Apply high-intensity NMES to the flexors to reduce tone
Provide static resting splint only and monitor

Correct answer: Refer for botulinum toxin injection and combine with task-specific training

Botulinum toxin combined with task-specific upper extremity training has the strongest evidence for reducing spasticity and improving function post-stroke.

Question 113: Which characteristic distinguishes nociceptive from neuropathic pain in clinical assessment?

Neuropathic pain arises from lesion or disease of the somatosensory nervous system (Correct answer)
Neuropathic pain always involves burning or electric shock quality
Nociceptive pain responds to NSAIDs while neuropathic pain never does
Nociceptive pain is always acute and neuropathic pain is always chronic

Correct answer: Neuropathic pain arises from lesion or disease of the somatosensory nervous system

The IASP defines neuropathic pain as pain arising as a direct consequence of a lesion or disease affecting the somatosensory system.

Question 114: Which intervention is best suited for improving sensory integration and motor function in children with developmental coordination disorder?

Constraint-Induced Movement Therapy
Sensory Integration Therapy (Correct answer)
Cognitive Rehabilitation Therapy
Neurodevelopmental Treatment (NDT)

Correct answer: Sensory Integration Therapy

Children with developmental coordination disorder (DCD) often struggle with processing and integrating sensory information, which impacts their motor planning and execution. Sensory Integration Therapy directly addresses these underlying sensory processing difficulties by providing controlled sensory experiences to help the child better organize and interpret sensory input. This improved sensory processing then facilitates enhanced motor planning and coordination.

Question 115: A patient demonstrates dysdiadochokinesia on neurological examination. Which cerebellar function does this deficit represent?

Coordination of eye movements
Smooth pursuit of visual targets
Rapid alternating movements of the hands (Correct answer)
Balance during single-leg stance

Correct answer: Rapid alternating movements of the hands

Dysdiadochokinesia is the inability to perform rapid alternating movements and is a hallmark sign of cerebellar dysfunction.

Question 116: A patient with central sensitization presents with allodynia. Which neuroplastic mechanism best explains this phenomenon?

Increased GABAergic inhibition in the spinal cord
Reduced substance P release at the synapse
Wind-up and long-term potentiation in dorsal horn neurons (Correct answer)
Peripheral nociceptor fatigue

Correct answer: Wind-up and long-term potentiation in dorsal horn neurons

Wind-up and LTP in dorsal horn neurons lower the activation threshold so normally non-painful stimuli become painful.

Question 117: What is Guillain-Barré syndrome?

A spinal cord tumor
A chronic pain syndrome
An autoimmune condition where the immune system attacks peripheral nerves, causing ascending weakness (Correct answer)
A brain infection

Correct answer: An autoimmune condition where the immune system attacks peripheral nerves, causing ascending weakness

GBS causes rapidly progressive weakness starting in the legs and ascending, potentially affecting breathing muscles.

Question 118: A 68-year-old patient with Guillain-Barré syndrome is in the plateau phase with 2/5 proximal lower extremity strength. Which therapy intensity is MOST appropriate?

High-intensity resistance training to maximize neuroplasticity
Low-to-moderate intensity activity with fatigue monitoring (Correct answer)
Passive ROM only to prevent contracture
Complete bed rest until full recovery

Correct answer: Low-to-moderate intensity activity with fatigue monitoring

During the GBS plateau phase, low-to-moderate intensity exercise with careful fatigue monitoring prevents deconditioning without risking exercise-induced exacerbation or overwork weakness.

Question 119: In the autonomic nervous system, postganglionic parasympathetic fibers release which neurotransmitter to act on target organs?

Acetylcholine acting on nicotinic receptors
Norepinephrine
Acetylcholine acting on muscarinic receptors (Correct answer)
Epinephrine

Correct answer: Acetylcholine acting on muscarinic receptors

Postganglionic parasympathetic fibers release acetylcholine that acts on muscarinic receptors of target organs, while nicotinic receptors are found at all autonomic ganglia.

Question 120: Duchenne muscular dystrophy (DMD) results from dystrophin deficiency. The primary pathophysiologic consequence of absent dystrophin is:

Failure of calcium release from the sarcoplasmic reticulum
Loss of mitochondrial ATP production in type II muscle fibers
Mechanical fragility of the sarcolemma leading to calcium influx and fiber necrosis (Correct answer)
Impaired cross-bridge cycling between actin and myosin

Correct answer: Mechanical fragility of the sarcolemma leading to calcium influx and fiber necrosis

Dystrophin stabilizes the sarcolemma by linking the cytoskeleton to the extracellular matrix; its absence allows membrane tears during contraction, permitting uncontrolled calcium influx that activates proteases and triggers myofiber necrosis.

Question 121: In a patient with headache attributed to intracranial hypertension, which pain management approach is contraindicated?

Continuous opioid infusion as primary treatment (Correct answer)
Repeated lumbar puncture
Acetazolamide for CSF pressure reduction
High-dose corticosteroids for idiopathic intracranial hypertension

Correct answer: Continuous opioid infusion as primary treatment

Opioids are generally contraindicated as primary treatment for elevated ICP headache because they can worsen CO2 retention and further increase intracranial pressure.

Question 122: Physical therapy for a child with Duchenne muscular dystrophy (DMD) should prioritize:

High-intensity eccentric strengthening to stimulate muscle hypertrophy
Daily electrical stimulation of affected proximal muscle groups
Progressive resistance training targeting hip extensors and knee extensors
Stretching to prevent contractures, functional mobility training, and respiratory support education (Correct answer)

Correct answer: Stretching to prevent contractures, functional mobility training, and respiratory support education

DMD management focuses on preventing contractures through stretching, maintaining ambulatory function, adaptive equipment, and preparing for respiratory support — aggressive or eccentric strengthening can accelerate muscle fiber damage.

Question 123: What are the stages of the Rancho Los Amigos Scale?

Three levels of consciousness
Two types of brain injury
Five stages of grief
Eight levels describing cognitive and behavioral recovery from TBI, from no response to purposeful behavior (Correct answer)

Correct answer: Eight levels describing cognitive and behavioral recovery from TBI, from no response to purposeful behavior

The Rancho scale tracks cognitive recovery from coma through confused states to purposeful, appropriate behavior.

Question 124: In lumbar spinal stenosis, neurogenic claudication differs from vascular claudication pathophysiologically because symptoms are precipitated by:

Positional compression of the cauda equina reducing intraneural blood flow and nerve conduction (Correct answer)
Lactic acid accumulation in the paraspinal musculature
Arterial insufficiency during increased metabolic demand
Venous pooling in the lower extremities with prolonged standing

Correct answer: Positional compression of the cauda equina reducing intraneural blood flow and nerve conduction

Lumbar extension narrows the spinal canal further, compressing the cauda equina, reducing intraneural perfusion, and impeding axonal conduction, causing pain relieved by flexion (shopping-cart sign) not just rest.

Question 125: Freezing of gait (FOG) in Parkinson's disease most commonly occurs during which situations?

Exclusively during backward walking tasks
Only in low-light environments
Gait initiation, turning, and passing through narrow spaces (Correct answer)
Mid-stride on straight, unobstructed pathways

Correct answer: Gait initiation, turning, and passing through narrow spaces

FOG is triggered by attentional demands or sensorimotor conflict, occurring most at gait initiation, during turns, in narrow spaces (doorways), and at destinations.

Question 126: In Huntington's disease, which of the following is the primary genetic mutation responsible for the condition?

Mutation in the PSEN1 gene causing tau hyperphosphorylation
Mutation in the SOD1 gene causing oxidative stress
Mutation in the APP gene causing amyloid-beta deposition
Mutation in the HTT gene causing CAG repeat expansion (Correct answer)

Correct answer: Mutation in the HTT gene causing CAG repeat expansion

Huntington's disease is an inherited neurodegenerative disorder caused by a dominant mutation in the HTT gene (Huntingtin gene). This specific mutation involves an abnormal expansion of a CAG trinucleotide repeat sequence within the gene. The increased number of CAG repeats leads to the production of an abnormally long and toxic huntingtin protein, which damages neurons, particularly in the basal ganglia, leading to the characteristic symptoms of the disease.

Question 127: What is neuroplasticity?

A surgical technique
The brain's ability to reorganize and form new neural connections after injury (Correct answer)
A medication for stroke
Brain swelling

Correct answer: The brain's ability to reorganize and form new neural connections after injury

Neuroplasticity enables recovery by allowing undamaged brain areas to take over functions of damaged areas.

Question 128: Which standardized tool measures functional independence across 18 items in motor and cognitive domains and is commonly used to track rehabilitation progress post-stroke?

FIM (Functional Independence Measure) (Correct answer)
Action Research Arm Test
Berg Balance Scale
10-Meter Walk Test

Correct answer: FIM (Functional Independence Measure)

The FIM is an 18-item scale measuring burden of care in motor and cognitive domains, widely used in inpatient rehabilitation to track functional progress.

Question 129: A neurologist prescribes duloxetine for a patient with diabetic peripheral neuropathy. What is the primary mechanism of analgesic action?

Serotonin-norepinephrine reuptake inhibition enhancing descending pain modulation (Correct answer)
NMDA receptor antagonism
Sodium channel blockade in peripheral nerves
COX-2 inhibition reducing prostaglandin synthesis

Correct answer: Serotonin-norepinephrine reuptake inhibition enhancing descending pain modulation

Duloxetine inhibits reuptake of serotonin and norepinephrine, strengthening descending inhibitory pathways that suppress pain signaling.

Question 130: Which quantitative sensory testing (QST) finding is most characteristic of small-fiber neuropathy causing neuropathic pain?

Elevated cold detection threshold and impaired heat pain threshold (Correct answer)
Elevated vibration detection threshold
Reduced nerve conduction velocity
Abnormal two-point discrimination

Correct answer: Elevated cold detection threshold and impaired heat pain threshold

Small-fiber neuropathy impairs Aδ and C fibers, elevating cold detection thresholds and altering heat pain thresholds on QST.

Question 131: A therapist is positioning a patient with severe flaccid hemiplegia to prevent glenohumeral subluxation. The MOST important positioning strategy is:

Supporting the humerus to maintain proper fossa alignment (Correct answer)
Elbow splint in 90° flexion
Wrist cock-up splint to prevent contracture
Elevated arm board with shoulder at 90° abduction

Correct answer: Supporting the humerus to maintain proper fossa alignment

Glenohumeral subluxation results from loss of rotator cuff support; proper positioning requires supporting the humerus to maintain the humeral head within the glenoid fossa.

Question 132: A 45-year-old with severe TBI has an intracranial pressure (ICP) of 28 mmHg refractory to mannitol. The next appropriate intervention is:

Lumbar puncture to drain CSF
Hypertonic saline (3% NaCl) infusion (Correct answer)
Prophylactic phenytoin administration
Immediate tracheostomy

Correct answer: Hypertonic saline (3% NaCl) infusion

Hypertonic saline is an effective second-line osmotherapy agent for refractory elevated ICP, creating an osmotic gradient to draw fluid from brain parenchyma into the vasculature.

Question 133: The Epley canalith repositioning maneuver for posterior canal BPPV guides canaliths from the posterior semicircular canal back into the:

Utricle (Correct answer)
Anterior semicircular canal
Cochlea
Endolymphatic sac

Correct answer: Utricle

The Epley maneuver uses four sequential head positions to move free-floating canaliths (otoconia) out of the posterior semicircular canal and back into the utricle where they cannot cause symptoms.

Question 134: When using the Task-Oriented Approach in stroke rehabilitation, the therapist's primary role is to:

Provide an optimal environment for the patient to solve motor problems (Correct answer)
Guide limb placement to reduce compensatory strategies
Facilitate normal movement patterns through hands-on techniques
Stretch spastic muscles before functional tasks

Correct answer: Provide an optimal environment for the patient to solve motor problems

In the Task-Oriented Approach, the therapist structures the task and environment to encourage active problem-solving and self-directed motor learning.

Question 135: Chronic inflammatory demyelinating polyneuropathy (CIDP) is distinguished from GBS clinically by:

The presence of CSF albuminocytologic dissociation
Facial nerve involvement occurring in both conditions
A course that progresses, relapses, or fails to plateau within 8 weeks (Correct answer)
Predominant axonal loss on nerve conduction studies

Correct answer: A course that progresses, relapses, or fails to plateau within 8 weeks

GBS plateaus by 4 weeks in nearly all cases; progression beyond 8 weeks or a relapsing-remitting course indicates CIDP, reflecting ongoing autoimmune demyelination rather than a monophasic post-infectious process.

Question 136: What is vestibular rehabilitation?

Therapy addressing balance and dizziness problems through specific exercises (Correct answer)
Medication for dizziness
Only inner ear surgery
Bed rest

Correct answer: Therapy addressing balance and dizziness problems through specific exercises

Vestibular rehabilitation uses specific exercises to retrain the balance system and reduce symptoms like vertigo and unsteadiness.

Question 137: According to the MGTX randomized trial, thymectomy in generalized AChR antibody-positive myasthenia gravis patients provides:

Benefit only in patients under age 30 with recent disease onset
Immediate complete remission in the majority of patients within 6 weeks
Improved clinical status and significant reduction in prednisone requirements over 3 years (Correct answer)
No benefit unless a thymoma is present on CT imaging

Correct answer: Improved clinical status and significant reduction in prednisone requirements over 3 years

The MGTX trial showed thymectomy significantly improved the Quantitative MG score and reduced prednisone doses at 3 years compared to prednisone alone in AChR-positive generalized MG, with sustained benefit.

Question 138: What is post-concussion syndrome?

A surgical complication
A psychological disorder unrelated to injury
Persistent symptoms including headache, dizziness, fatigue, and cognitive difficulties lasting weeks to months after mild TBI (Correct answer)
A type of brain tumor

Correct answer: Persistent symptoms including headache, dizziness, fatigue, and cognitive difficulties lasting weeks to months after mild TBI

PCS symptoms can persist long after the initial injury has healed, affecting quality of life and function.

Question 139: What are the two main types of stroke?

Neither is classified as stroke
Only ischemic
Ischemic (blocked blood flow) and hemorrhagic (bleeding in the brain) (Correct answer)
Only hemorrhagic

Correct answer: Ischemic (blocked blood flow) and hemorrhagic (bleeding in the brain)

Ischemic strokes (87%) involve blood vessel blockage; hemorrhagic strokes involve vessel rupture.

Question 140: A patient presents with ipsilateral Horner syndrome, ipsilateral facial sensory loss, and contralateral limb pain/temperature loss. Which structure is most likely affected?

Internal capsule
Ventral pons
Midbrain tegmentum
Dorsolateral medulla (Correct answer)

Correct answer: Dorsolateral medulla

Lateral medullary (Wallenberg) syndrome results from occlusion of the posterior inferior cerebellar artery affecting the dorsolateral medulla, producing this classic crossed sensory pattern.

Question 141: Which fall risk factor is MOST specific to the post-stroke population compared to the general older adult population?

Unilateral spatial neglect (Correct answer)
Urinary incontinence
Orthostatic hypotension
Polypharmacy

Correct answer: Unilateral spatial neglect

Unilateral spatial neglect is a stroke-specific impairment that significantly increases fall risk by causing unawareness of obstacles and body position on the neglected side.

Question 142: A patient post-cerebellar stroke demonstrates limb ataxia and dysdiadochokinesia. When selecting functional goals, the therapist should prioritize interventions targeting:

Strengthening with high-resistance progressive overload
Spasticity reduction via PNF stretching patterns
Proprioceptive neuromuscular facilitation diagonal patterns only
Coordination and timing through task-specific repetitive practice (Correct answer)

Correct answer: Coordination and timing through task-specific repetitive practice

Cerebellar ataxia responds best to repetitive, task-specific practice that trains timing and coordination rather than strength or tone management.

Question 143: In complex regional pain syndrome (CRPS), which finding differentiates Type I from Type II?

Documented nerve injury in Type II (Correct answer)
Skin temperature changes in Type II only
Presence of allodynia
Sympathetically maintained pain in Type I only

Correct answer: Documented nerve injury in Type II

CRPS Type II (formerly causalgia) is distinguished by a confirmed peripheral nerve injury, whereas Type I occurs without identifiable nerve damage.

Question 144: What are common gait deviations in neurological conditions?

Hemiplegic gait, scissor gait, festinating gait, ataxic gait, and steppage gait (Correct answer)
All neurological patients walk normally
Only wheelchair dependence
Only limping

Correct answer: Hemiplegic gait, scissor gait, festinating gait, ataxic gait, and steppage gait

Different neurological conditions produce characteristic walking patterns that help with diagnosis.

Question 145: Neuroplasticity following stroke or CNS injury is best described as which process at the cellular level?

Replacement of lost neurons by neural stem cells in all brain regions
Glial cell transformation into functional neurons
Synaptic reorganization, axonal sprouting, and unmasking of latent connections (Correct answer)
Axonal regeneration through the glial scar

Correct answer: Synaptic reorganization, axonal sprouting, and unmasking of latent connections

CNS plasticity following injury is primarily mediated through LTP-like synaptic strengthening, dendritic sprouting, unmasking of pre-existing but inactive synaptic connections, and cortical map reorganization rather than true axon regeneration.

Question 146: A patient 3 months post-severe TBI exhibits marked impulsivity, disinhibition, and poor judgment. Which brain region is most likely primarily affected?

Hippocampus
Primary motor cortex
Prefrontal cortex (orbitofrontal/dorsolateral) (Correct answer)
Cerebellum

Correct answer: Prefrontal cortex (orbitofrontal/dorsolateral)

The prefrontal cortex—particularly the orbitofrontal and dorsolateral regions—governs executive function, impulse control, and social judgment, and is highly vulnerable in TBI.

Question 147: Which of the following is the most appropriate initial goal for a patient with a recent stroke presenting with significant hemiparesis?

Restore full sensory function in the affected limb.
Achieve full resolution of upper extremity motor deficits.
Improve gait speed to pre-stroke levels.
Enhance safety and independence in basic activities of daily living (ADLs). (Correct answer)

Correct answer: Enhance safety and independence in basic activities of daily living (ADLs).

For a patient with significant hemiparesis after a stroke, the initial goal must prioritize safety and fundamental independence. Enhancing safety and independence in basic activities of daily living (ADLs) such as dressing, feeding, and transfers is crucial for immediate well-being and reduces caregiver burden. More advanced goals like restoring pre-stroke gait speed or full motor function are typically long-term objectives, built upon a foundation of basic functional independence.

Question 148: Paroxysmal sympathetic hyperactivity (PSH) after severe TBI is characterized by episodic increases in which combination of signs?

Heart rate, blood pressure, temperature, sweating, and posturing (Correct answer)
Heart rate, intracranial pressure, pupil dilation, and bradypnea
Temperature, heart rate, urinary retention, and bradycardia
Blood pressure, respiratory rate, miosis, and salivation

Correct answer: Heart rate, blood pressure, temperature, sweating, and posturing

PSH is defined by simultaneous paroxysmal increases in heart rate, blood pressure, temperature, diaphoresis, and tachypnea, often accompanied by extensor posturing.

Question 149: Which reflex, when present in an adult, is considered pathological and suggests corticospinal tract dysfunction?

Patellar reflex (L3-L4)
Biceps reflex (C5-C6)
Plantar grasp reflex (Babinski sign) (Correct answer)
Brachioradialis reflex (C5-C6)

Correct answer: Plantar grasp reflex (Babinski sign)

The Babinski sign (upgoing great toe with fanning of toes on plantar stroking) is normal in infants but pathological in adults, indicating UMN lesion.

Question 150: Anterior cord syndrome carries the poorest prognosis for motor recovery because it specifically damages the:

Lateral corticospinal tracts only while sparing anterior motor neurons
Corticospinal and spinothalamic tracts while sparing the posterior columns (Correct answer)
Dorsal columns carrying proprioception and vibration sense
Entire cord cross-section including all ascending and descending tracts

Correct answer: Corticospinal and spinothalamic tracts while sparing the posterior columns

Anterior cord syndrome destroys the corticospinal and spinothalamic tracts while sparing posterior column function (vibration and proprioception), yet motor prognosis is very poor.

Question 151: The Sensory Organization Test (SOT), a component of computerized dynamic posturography, evaluates the relative contributions of which three sensory systems to balance?

Visual, vestibular, and somatosensory (Correct answer)
Tactile, visual, and auditory
Proprioceptive, auditory, and vestibular
Auditory, proprioceptive, and visual

Correct answer: Visual, vestibular, and somatosensory

The SOT systematically alters visual and surface conditions across six conditions to isolate the relative contributions of visual, vestibular, and somatosensory inputs to postural control.

Question 152: During tilt table training for a patient with severe TBI who has been bedbound for 6 weeks, what finding requires immediate return to supine?

Respiratory rate increase of 4 breaths per minute from baseline
Oxygen saturation decrease to 96% with no associated symptoms
Heart rate increase of 10 bpm above supine baseline with no symptoms
Systolic blood pressure drop of 20 mmHg with concurrent dizziness and pallor (Correct answer)

Correct answer: Systolic blood pressure drop of 20 mmHg with concurrent dizziness and pallor

Orthostatic hypotension is defined as a systolic BP drop ≥20 mmHg accompanied by symptoms such as dizziness or pallor, requiring immediate return to supine to prevent syncope.

Question 153: A patient demonstrates a positive Romberg test (falls with eyes closed) but normal tandem gait with eyes open. This pattern best implicates which system as the primary contributor to balance impairment?

Visual system as the dominant deficit
Cerebellar dysfunction
Somatosensory (proprioceptive) system (Correct answer)
Vestibular system only

Correct answer: Somatosensory (proprioceptive) system

The Romberg test isolates somatosensory input; falling only with vision removed points to proprioceptive deficit as the primary balance impairment.

Question 154: When using the OPTIMAL theory of motor learning in neurorehabilitation, the therapist enhances patient autonomy by:

Prescribing therapist-determined goals without patient input
Providing blocked practice and constant external feedback
Allowing patients to choose practice order, schedule, and feedback timing (Correct answer)
Using frequent augmented feedback after every repetition

Correct answer: Allowing patients to choose practice order, schedule, and feedback timing

OPTIMAL theory emphasizes autonomy support (patient choice), enhanced expectancies, and attentional focus to optimize motor learning.

Question 155: A post-stroke patient exhibits pusher syndrome (ipsilateral pushing). Which intervention strategy is MOST evidence-supported for this condition?

Vestibular rehabilitation exercises in supine
Visual and verbal feedback about true vertical orientation during weight transfer (Correct answer)
Splinting the unaffected arm to prevent pushing
Strengthening the non-paretic side to overcome the pushing

Correct answer: Visual and verbal feedback about true vertical orientation during weight transfer

Pusher syndrome is driven by a misperception of body vertical; evidence supports using visual references (mirrors, plumb lines) and verbal feedback during upright tasks to recalibrate vertical perception.

Question 156: When using the ICF model to guide clinical decision-making for a patient with ALS, which framework element best addresses the patient's inability to return to work as a teacher?

Participation restriction (Correct answer)
Environmental barrier
Activity limitation
Body structure and function

Correct answer: Participation restriction

Inability to fulfill societal roles such as employment is classified under participation restriction in the ICF framework.

Question 157: For a patient post-stroke with foot drop and significant mediolateral ankle instability, which AFO design provides the GREATEST mediolateral control?

Prefabricated carbon fiber foot-up splint with medial strapping
Solid ankle AFO with trimlines extending anterior to the malleoli bilaterally (Correct answer)
Articulated (hinged) AFO with a plantar flexion stop only
Posterior leaf spring (PLS) AFO with narrow trimlines posterior to the malleoli

Correct answer: Solid ankle AFO with trimlines extending anterior to the malleoli bilaterally

A solid ankle AFO with trimlines anterior to the malleoli encapsulates the hindfoot rigidly and provides maximum mediolateral stability compared to more flexible designs.

Question 158: A patient with MS demonstrates heat sensitivity (Uhthoff's phenomenon) and has a therapy session scheduled during warm afternoon hours. The best clinical decision is to:

Increase session intensity to build heat tolerance
Cancel the session and reschedule for evening
Administer aquatic therapy in a heated pool
Schedule the session in cooler morning hours and use cooling strategies (Correct answer)

Correct answer: Schedule the session in cooler morning hours and use cooling strategies

Scheduling therapy in cooler conditions and using cooling vests or cold towels minimizes Uhthoff's phenomenon in MS patients.

Question 159: Nerve conduction studies in acute inflammatory demyelinating polyneuropathy (AIDP/GBS) most characteristically show:

Asymmetric axonal sensory loss with normal motor conduction velocities
Reduced CMAP amplitudes with normal distal latencies and conduction velocities
Prolonged distal latencies, slow conduction velocities, conduction block, and prolonged F-waves (Correct answer)
Normal NCS with abnormal EMG fibrillations only

Correct answer: Prolonged distal latencies, slow conduction velocities, conduction block, and prolonged F-waves

AIDP is a demyelinating process; NCS shows hallmark demyelinating features including prolonged distal latencies, reduced conduction velocities, conduction block, temporal dispersion, and prolonged or absent F-waves.

Question 160: Upper motor neuron (UMN) lesions produce which combination of clinical signs?

Tremor at rest, cogwheel rigidity, bradykinesia
Spastic paralysis, hyperreflexia, positive Babinski sign, clonus (Correct answer)
Flaccid paralysis, hyporeflexia, fasciculations, muscle atrophy
Flaccid paralysis, areflexia, loss of sphincter tone

Correct answer: Spastic paralysis, hyperreflexia, positive Babinski sign, clonus

UMN lesions (above the anterior horn cell) characteristically produce spasticity, hyperreflexia, Babinski sign, and clonus due to loss of descending inhibitory control on the stretch reflex arc.

Question 161: A patient with Brown-Séquard syndrome (right-sided spinal cord hemisection at T10) would exhibit which combination of deficits relevant to gait assessment?

Bilateral loss of all sensation and motor function below T10
Right motor weakness and loss of proprioception; left loss of pain and temperature (Correct answer)
Right loss of pain and temperature; left motor weakness and loss of proprioception
Left motor weakness; right loss of all sensation below T10

Correct answer: Right motor weakness and loss of proprioception; left loss of pain and temperature

Brown-Séquard syndrome produces ipsilateral (right) loss of motor function, proprioception, and vibration sense, and contralateral (left) loss of pain and temperature sensation below the lesion.

Question 162: A patient with MS is participating in an aerobic exercise program. Which principle is MOST critical to prevent Uhthoff's phenomenon?

Avoiding all aerobic exercise due to the risk of symptom exacerbation
Limiting all exercise sessions to a maximum of 15 minutes regardless of intensity
Monitoring core body temperature and employing pre-cooling or cooling strategies to prevent overheating (Correct answer)
Scheduling exercise exclusively in the morning when ambient and body temperatures are lowest

Correct answer: Monitoring core body temperature and employing pre-cooling or cooling strategies to prevent overheating

Uhthoff's phenomenon results from elevated core body temperature worsening conduction in demyelinated axons; pre-cooling strategies and temperature monitoring are the primary preventive measures.

Question 163: What are the cranial nerves?

Blood vessels in the brain
Muscles in the skull
Twelve pairs of nerves emerging directly from the brain, each with specific sensory or motor functions (Correct answer)
Nerves in the spine only

Correct answer: Twelve pairs of nerves emerging directly from the brain, each with specific sensory or motor functions

The 12 cranial nerve pairs control functions from smell and vision to facial expression and swallowing.

Question 164: A patient recovering from a TBI scores 6 on the Rancho Los Amigos Scale. The therapist's clinical decision for this level should primarily focus on:

Coma stimulation protocols and passive ROM only
Independent ADL training in an unstructured environment
Managing confused-appropriate responses with structured, consistent routines (Correct answer)
Vocational rehabilitation and community reintegration

Correct answer: Managing confused-appropriate responses with structured, consistent routines

Rancho Level VI (Confused-Appropriate) patients benefit from structured, consistent routines that reduce confusion while beginning purposeful task training.

Question 165: Microglia serve as the primary innate immune effectors of the CNS. In neuroinflammation, activated microglia cause secondary neuronal injury primarily through release of:

Acetylcholine impairing synaptic vesicle recycling
Pro-inflammatory cytokines (IL-1β, TNF-α), reactive oxygen species, and glutamate (Correct answer)
Excessive GABA reducing neuronal excitability below viable thresholds
Complement proteins that demyelinate intact axons

Correct answer: Pro-inflammatory cytokines (IL-1β, TNF-α), reactive oxygen species, and glutamate

Activated M1-polarized microglia release TNF-α, IL-1β, IL-6, ROS, and excessive glutamate, creating an excitotoxic and oxidatively stressful environment that amplifies neuronal damage beyond the initial injury.

Question 166: A patient post-traumatic brain injury demonstrates executive dysfunction affecting therapy compliance. The most effective clinical decision for session structure is:

Allow the patient to self-direct all therapy decisions to build autonomy
Use complex multi-step instructions to challenge executive function
Reduce session frequency as compliance cannot be improved neurologically
Provide simple, consistent routines with visual schedules and external cuing systems (Correct answer)

Correct answer: Provide simple, consistent routines with visual schedules and external cuing systems

External supports — visual schedules, consistent routines, and cuing — compensate for impaired executive function and improve therapy compliance post-TBI.

Question 167: In sports-related concussion management, 'second impact syndrome' refers to:

A second concussion sustained while still symptomatic from the first, causing catastrophic cerebral swelling (Correct answer)
Cumulative cognitive deficits from multiple concussions over a career
Rebound headache from overuse of analgesics after concussion
Repetitive subconcussive impacts causing chronic traumatic encephalopathy

Correct answer: A second concussion sustained while still symptomatic from the first, causing catastrophic cerebral swelling

Second impact syndrome occurs when a second concussion is sustained before full recovery from the first, causing loss of cerebrovascular autoregulation and potentially fatal diffuse cerebral swelling.

Question 168: Spinal shock following acute SCI is best characterized by:

Transient areflexia, flaccidity, and loss of autonomic function below the injury (Correct answer)
Hypertension and spasticity below the injury level
Permanent loss of all reflex activity and motor function
Hyperreflexia and autonomic instability in the acute phase

Correct answer: Transient areflexia, flaccidity, and loss of autonomic function below the injury

Spinal shock is a transient physiological depression of spinal cord function presenting with flaccidity, areflexia, and autonomic dysfunction below the injury level.

Question 169: Which EEG finding is most associated with non-convulsive status epilepticus (NCSE) in a TBI patient who has unexplained decreased consciousness?

Periodic lateralized epileptiform discharges (PLEDs) evolving to ictal pattern (Correct answer)
Burst suppression pattern
Diffuse slowing with theta activity
Symmetric alpha coma pattern

Correct answer: Periodic lateralized epileptiform discharges (PLEDs) evolving to ictal pattern

PLEDs that evolve into rhythmic ictal discharges on EEG are a hallmark finding for NCSE, which can cause unexplained coma or encephalopathy after TBI.

Question 170: The Disorders of Consciousness Scale (DOCS) is designed to assess patients at which level of recovery?

Rancho Los Amigos Levels IV–VI (confusion to appropriate behavior)
Rancho Los Amigos Levels VII–VIII (automatic to purposeful behavior)
Rancho Los Amigos Levels I–III (coma to localized response) (Correct answer)
Post-acute community reintegration

Correct answer: Rancho Los Amigos Levels I–III (coma to localized response)

The DOCS is a standardized scale used with patients in coma or vegetative/minimally conscious states (Rancho Levels I–III) to assess and track sensory responsiveness.

Question 171: A patient with acute unilateral vestibular neuritis would most likely demonstrate which finding on examination?

Spontaneous nystagmus beating toward the affected side
Pure vertical downbeat nystagmus
Positive head impulse test when the head is thrust toward the affected side (Correct answer)
Bilateral symmetric caloric weakness

Correct answer: Positive head impulse test when the head is thrust toward the affected side

Unilateral vestibular neuritis causes ipsilesional VOR deficit, resulting in a positive head impulse test (visible corrective saccade) when the head is rapidly thrust toward the lesioned side.

Question 172: Charcot-Marie-Tooth type 1A (CMT1A) is caused by a duplication of which gene, resulting in demyelinating peripheral neuropathy?

GDAP1
GJB1 (connexin 32)
MPZ (myelin protein zero)
PMP22 (peripheral myelin protein 22) (Correct answer)

Correct answer: PMP22 (peripheral myelin protein 22)

CMT1A results from a 17p11.2 duplication causing PMP22 overexpression, which disrupts Schwann cell myelination, producing slowed NCS velocities and onion-bulb formations on nerve biopsy.

Question 173: Which finding on skin punch biopsy would confirm a diagnosis of small-fiber neuropathy (SFN) as the cause of burning extremity pain?

Axonal swelling in large-caliber sensory fibers
Demyelination of large myelinated fibers
Presence of inflammatory infiltrate around epineurial vessels
Reduced intraepidermal nerve fiber density (IENFD) below the 5th percentile (Correct answer)

Correct answer: Reduced intraepidermal nerve fiber density (IENFD) below the 5th percentile

Reduced IENFD on skin punch biopsy, typically from the distal leg, is the gold standard pathological confirmation of small-fiber neuropathy.

Question 174: What is a pupil assessment and why is it important?

Only checking vision clarity
Evaluating pupil size, equality, and reactivity to light — changes may indicate neurological deterioration (Correct answer)
A cosmetic evaluation
An eye color assessment

Correct answer: Evaluating pupil size, equality, and reactivity to light — changes may indicate neurological deterioration

Pupil changes (unequal size, fixed dilation) can indicate brain herniation or cranial nerve damage.

Question 175: The Sensory Organization Test (SOT) of computerized dynamic posturography evaluates the integration of which three sensory systems?

Proprioceptive, auditory, and vestibular
Visual, auditory, and proprioceptive
Visual, vestibular, and somatosensory (Correct answer)
Auditory, vestibular, and visual

Correct answer: Visual, vestibular, and somatosensory

The SOT systematically manipulates visual, vestibular, and somatosensory inputs across 6 conditions to quantify each system's contribution to postural control.

Question 176: A neurologic PT uses the minimal clinically important difference (MCID) for the Berg Balance Scale (reported as 4 points) to evaluate treatment effectiveness. The patient improved from 38 to 41. The correct clinical decision is:

The intervention was clinically meaningful because any improvement is positive
The 3-point improvement does not meet MCID; re-evaluate intervention approach (Correct answer)
Discharge the patient as the goal was achieved
Increase sessions to 5 days per week immediately

Correct answer: The 3-point improvement does not meet MCID; re-evaluate intervention approach

A 3-point BBS improvement falls below the 4-point MCID, meaning the change is not clinically meaningful and warrants intervention re-evaluation.

Question 177: What is the primary goal of using clinical decision-making frameworks in neurologic practice?

To reduce the number of diagnostic tests ordered
To streamline documentation processes
To make informed, evidence-based decisions tailored to individual patient needs (Correct answer)
To ensure all patients receive the same treatment regardless of their condition

Correct answer: To make informed, evidence-based decisions tailored to individual patient needs

Clinical decision-making frameworks provide a structured approach for healthcare professionals to integrate the best available research evidence, clinical expertise, and patient values. Their primary goal is to guide the development of individualized, evidence-based treatment plans. This ensures that interventions are tailored to each patient's unique condition, preferences, and circumstances, leading to optimal and effective care.

Question 178: Lambert-Eaton myasthenic syndrome (LEMS) differs from myasthenia gravis pathophysiologically in that LEMS involves antibodies against:

MuSK (muscle-specific kinase) at the NMJ scaffold
Voltage-gated calcium channels on the presynaptic motor nerve terminal (Correct answer)
Acetylcholine receptors on the postsynaptic muscle membrane
Acetylcholinesterase within the synaptic cleft

Correct answer: Voltage-gated calcium channels on the presynaptic motor nerve terminal

LEMS antibodies target presynaptic P/Q-type VGCC, reducing calcium influx and impairing acetylcholine vesicle release, which paradoxically improves transiently with repeated activation (facilitation).

Question 179: The pain of central post-stroke syndrome (CPSP) most commonly follows infarction involving which brain region?

Frontal lobe
Cerebellum
Thalamus (especially VPL nucleus) (Correct answer)
Basal ganglia

Correct answer: Thalamus (especially VPL nucleus)

Thalamic infarction, particularly of the ventroposterolateral nucleus, is the most common lesion site in CPSP due to disruption of spinothalamic input processing.

Question 180: A patient with ALS demonstrates dysphagia and reduced respiratory reserve. Which team member should the PT PRIMARILY coordinate with regarding positioning to optimize both swallowing and breathing?

Social worker
Speech-language pathologist and respiratory therapist (Correct answer)
Dietitian alone
Occupational therapist

Correct answer: Speech-language pathologist and respiratory therapist

In ALS, swallowing safety (SLP domain) and respiratory muscle weakness (RT domain) both influence optimal postural positioning, requiring coordinated collaboration between these two specialists.

Question 181: What systems contribute to balance?

Only the inner ear
Only the eyes
Only the brain
Visual, vestibular (inner ear), and somatosensory (proprioception) systems working together (Correct answer)

Correct answer: Visual, vestibular (inner ear), and somatosensory (proprioception) systems working together

Balance requires integration of information from three sensory systems.

Question 182: Brown-Séquard syndrome results from cord hemisection and presents with:

Bilateral loss of pain and temperature sensation with preserved motor function
Bilateral motor loss with preserved pain and temperature sensation
Contralateral loss of all motor and sensory function below the injury level
Ipsilateral loss of motor function, proprioception, and vibration; contralateral loss of pain and temperature (Correct answer)

Correct answer: Ipsilateral loss of motor function, proprioception, and vibration; contralateral loss of pain and temperature

Brown-Séquard syndrome causes ipsilateral motor and dorsal column loss with contralateral spinothalamic (pain/temperature) loss due to hemisection.

Question 183: In myasthenia gravis (AChR-antibody positive), the primary pathophysiologic mechanism causing fatigable weakness is:

Antibody-mediated destruction and blockade of postsynaptic AChR (Correct answer)
Impaired voltage-gated calcium channel function at the NMJ
Degeneration of the motor neuron axon terminal
Presynaptic failure to release acetylcholine vesicles

Correct answer: Antibody-mediated destruction and blockade of postsynaptic AChR

AChR antibodies cause complement-mediated destruction of the postsynaptic membrane, receptor internalization, and direct blockade, reducing the end-plate potential below the threshold for action potential generation.

Question 184: A solid ankle foot orthosis (AFO) prescribed for foot drop following a CVA provides its PRIMARY biomechanical benefit during which phase of gait?

Swing phase by preventing excessive plantarflexion (Correct answer)
Loading response by absorbing ground reaction forces
Mid-stance by reducing mediolateral ankle instability
Terminal stance by enhancing push-off power

Correct answer: Swing phase by preventing excessive plantarflexion

A solid AFO maintains the foot in neutral dorsiflexion, preventing the plantarflexion that would cause tripping or toe drag during the swing phase of gait.

Question 185: In the context of clinical decision-making for a patient with Parkinson’s disease, which of the following interventions would most likely be recommended to address motor fluctuations?

Introducing a dopamine agonist medication (Correct answer)
Implementing a high-protein diet
Increasing the frequency of physical therapy sessions
Reducing the dosage of levodopa

Correct answer: Introducing a dopamine agonist medication

Motor fluctuations in Parkinson's disease, such as 'wearing off' or dyskinesias, occur as the effectiveness of levodopa fluctuates throughout the day. Dopamine agonists mimic the effect of dopamine in the brain, providing a more continuous dopaminergic stimulation. This helps to smooth out motor fluctuations, extend 'on' times, and improve overall motor control, making them a key intervention for managing these symptoms.

Question 186: What is the Babinski sign?

A normal reflex in adults
An abnormal reflex where the great toe extends upward when the sole is stroked, indicating upper motor neuron damage (Correct answer)
A test for hearing
A blood pressure measurement

Correct answer: An abnormal reflex where the great toe extends upward when the sole is stroked, indicating upper motor neuron damage

Babinski's sign is normal in infants but indicates upper motor neuron pathology in adults.

Question 187: What is the autonomic nervous system?

The division controlling involuntary functions like heart rate, digestion, and breathing (Correct answer)
Only pain sensation
Only the brain
The system for voluntary movement

Correct answer: The division controlling involuntary functions like heart rate, digestion, and breathing

The ANS operates automatically, controlling vital functions without conscious thought.

Question 188: The Montreal Cognitive Assessment (MoCA) tests multiple cognitive domains; what is the maximum score and the generally accepted cutoff for normal cognition?

10 points total, ≥8 normal
30 points total, ≥26 normal (Correct answer)
20 points total, ≥15 normal
50 points total, ≥40 normal

Correct answer: 30 points total, ≥26 normal

The MoCA is scored 0-30, with a score of ≥26 considered normal and scores below indicating possible mild cognitive impairment.

Question 189: Central sensitization as a mechanism of neuropathic pain is best characterized by:

Peripheral nociceptor threshold lowering due to prostaglandin release
Amplified synaptic transmission in dorsal horn neurons persisting beyond the initial injury (Correct answer)
Degeneration of descending inhibitory pathways from the periaqueductal gray
Complete loss of myelinated A-delta fiber function

Correct answer: Amplified synaptic transmission in dorsal horn neurons persisting beyond the initial injury

Central sensitization involves wind-up and long-term potentiation at dorsal horn synapses, mediated by NMDA receptor activation, causing hyperalgesia and allodynia that outlast the peripheral stimulus.

Question 190: A patient maintains balance with eyes open but sways and falls with eyes closed during the Romberg test. This positive Romberg sign most strongly implicates which system?

Somatosensory/proprioceptive system (Correct answer)
Visual system
Cerebellar coordination
Vestibular system

Correct answer: Somatosensory/proprioceptive system

A positive Romberg sign indicates somatosensory/proprioceptive dysfunction, where the patient was using vision to compensate for impaired proprioceptive input.

Question 191: A patient presents with loss of pain and temperature sensation on the contralateral side with ipsilateral motor weakness below the lesion. Which spinal cord syndrome is most consistent?

Anterior cord syndrome
Brown-Séquard syndrome (Correct answer)
Central cord syndrome
Posterior cord syndrome

Correct answer: Brown-Séquard syndrome

Brown-Séquard syndrome results from hemisection of the spinal cord, causing ipsilateral motor loss and contralateral loss of pain/temperature.

Question 192: What is the best approach for managing a patient with chronic migraine who has not responded to first-line pharmacological treatments?

Recommend immediate surgical intervention
Consider a second-line medication such as a CGRP inhibitor (Correct answer)
Discontinue all medications and recommend lifestyle changes only
Increase the dosage of the initial medication to maximum levels

Correct answer: Consider a second-line medication such as a CGRP inhibitor

For patients with chronic migraine who have not responded to first-line pharmacological treatments, it is appropriate to consider second-line options. CGRP (calcitonin gene-related peptide) inhibitors are a newer class of medications specifically designed to target the CGRP pathway, which plays a crucial role in migraine pathophysiology. They have demonstrated significant efficacy in reducing migraine frequency and severity in patients refractory to other treatments, offering a targeted and effective alternative.

Question 193: A 45-year-old patient with multiple sclerosis reports vision problems. Which cranial nerve assessment would be most relevant to evaluate internuclear ophthalmoplegia?

CN III, IV, VI testing via smooth pursuit and saccades (Correct answer)
CN V testing via corneal reflex
CN II testing via visual acuity chart
CN VII testing via facial symmetry

Correct answer: CN III, IV, VI testing via smooth pursuit and saccades

Internuclear ophthalmoplegia (common in MS) is detected by testing extraocular movements via CN III, IV, and VI, revealing adduction weakness with contralateral nystagmus.

Question 194: On the 10-meter walk test, a gait speed below which threshold is associated with increased risk of mortality and institutionalization in community-dwelling older adults?

Below 0.8 m/s (Correct answer)
Below 0.5 m/s
Below 1.0 m/s
Below 1.2 m/s

Correct answer: Below 0.8 m/s

A 10-meter walk test speed below 0.8 m/s in community-dwelling older adults is associated with increased mortality risk, hospitalization, and loss of community independence.

Question 195: Pregabalin's analgesic mechanism in neuropathic pain involves binding to which target?

α2δ subunit of voltage-gated calcium channels (Correct answer)
NMDA receptor glycine site
GABA-B receptors
Voltage-gated sodium channels

Correct answer: α2δ subunit of voltage-gated calcium channels

Pregabalin binds to the α2δ-1 subunit of voltage-gated calcium channels, reducing calcium influx and subsequent excitatory neurotransmitter release at synapses.

Question 196: Body-weight supported treadmill training (BWSTT) is most appropriate for which post-stroke patient profile?

Full independent ambulation with normal gait pattern
Complete inability to bear any weight through the lower extremities
Partial weight-bearing capacity but insufficient strength for unsupported overground gait (Correct answer)
Community ambulators who want to improve running performance

Correct answer: Partial weight-bearing capacity but insufficient strength for unsupported overground gait

BWSTT is indicated for patients with residual lower extremity function who cannot yet bear full weight, as partial unloading allows practice of neuromuscular gait patterns before full weight-bearing is achieved.

Question 197: A therapist must decide when to progress a patient with incomplete SCI from parallel bars to lofstrand crutches. The most critical factor informing this decision is:

Demonstrated trunk and lower extremity strength, balance, and safety within parallel bars (Correct answer)
Patient motivation and self-reported confidence
Age and prior ambulatory status before injury
Time since injury exceeding 3 months

Correct answer: Demonstrated trunk and lower extremity strength, balance, and safety within parallel bars

Progression to Lofstrand crutches requires demonstrated sufficient trunk control, LE strength, and safe balance within the parallel bars.

Question 198: Vincristine-induced peripheral neuropathy most characteristically presents as:

Isolated large-fiber sensory neuropathy with preserved motor function
Acute demyelinating polyradiculoneuropathy resembling GBS
Predominantly proximal motor weakness with preserved distal sensation
Distal axonal sensorimotor neuropathy with early loss of ankle deep tendon reflexes (Correct answer)

Correct answer: Distal axonal sensorimotor neuropathy with early loss of ankle deep tendon reflexes

Vincristine disrupts axonal microtubule polymerization, impairing axonal transport in a length-dependent fashion; this causes early ankle areflexia, distal paresthesias, and then distal weakness — a classic dose-dependent axonal sensorimotor neuropathy.

Question 199: When measuring spasticity in a patient with multiple sclerosis, which scale quantifies resistance to passive movement across a velocity spectrum?

Modified Ashworth Scale (MAS)
Ashworth Scale
Numerical Rating Scale (NRS)
Tardieu Scale (Correct answer)

Correct answer: Tardieu Scale

The Tardieu Scale assesses spasticity at both slow and fast velocities, capturing the velocity-dependent nature of spastic resistance that the Modified Ashworth Scale cannot distinguish.

Question 200: A 72-year-old patient with diabetic peripheral neuropathy and a Berg Balance Scale score of 42 is being evaluated. The most appropriate clinical decision is to:

Refer directly to orthotics for custom AFOs before initiating therapy
Implement a progressive balance and strengthening program with fall prevention education (Correct answer)
Recommend no exercise due to neuropathic sensory loss
Discharge as BBS indicates minimal fall risk

Correct answer: Implement a progressive balance and strengthening program with fall prevention education

A BBS score of 42 indicates moderate fall risk (cut-off ~45), warranting a targeted balance and strengthening program with fall prevention strategies.
