NCS Stroke Rehabilitation 3

Question 1

Constraint-Induced Movement Therapy (CIMT) is BEST indicated for which post-stroke patient profile?

Accepted Answer

At least 10° active wrist extension and 10° active finger extension in affected hand

Answer

Flaccid hemiplegia with no active wrist extension

Answer

Complete paralysis of the affected upper extremity

Answer

Severe cognitive impairment limiting task follow-through

Question 2

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

Accepted Answer

Use-dependent cortical reorganization

Answer

Use it or lose it

Answer

Cross-education

Answer

Diaschisis resolution

Question 3

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

Accepted Answer

Activating central pattern generators in the lumbar spinal cord

Answer

Reducing cardiovascular demand

Answer

Strengthening hip flexors through loaded stepping

Answer

Improving cerebellar coordination via visual feedback

Question 4

A patient 3 months post-stroke has a flaccid affected lower extremity. Which intervention is MOST appropriate to facilitate early stance stability?

Accepted Answer

Functional electrical stimulation (FES) to quadriceps during stance

Answer

Knee immobilizer during ambulation

Answer

Ankle-foot orthosis (AFO) with rigid footplate

Answer

Hamstring strengthening exercises

Question 5

Mirror therapy for post-stroke upper extremity rehabilitation works primarily through which mechanism?

Accepted Answer

Activating the motor cortex via visual illusion of affected limb movement

Answer

Increasing afferent proprioceptive input to the sensory cortex

Answer

Strengthening the unaffected limb through cross-education

Answer

Reducing spasticity through reciprocal inhibition

Question 6

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

Accepted Answer

Overlapping cortical motor networks used during actual movement

Answer

Cerebellum via internal forward models

Answer

Basal ganglia reward pathways

Answer

Reticulospinal tracts for postural tone

Question 7

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

Accepted Answer

Provide an optimal environment for the patient to solve motor problems

Answer

Facilitate normal movement patterns through hands-on techniques

Answer

Stretch spastic muscles before functional tasks

Answer

Guide limb placement to reduce compensatory strategies
