CNS Motor Control and Motor Learning 3

Question 1

According to Schmidt's Schema Theory, a Generalized Motor Program (GMP) is BEST described as:

Accepted Answer

An abstract movement representation sharing a relative timing structure that can be scaled for different movement parameters

Answer

An invariant motor command stored for a single specific movement such as one particular handwriting stroke

Answer

A reflexive motor pattern stored in the spinal cord for stereotyped movements

Answer

A declarative memory trace for explicit movement sequences learned through verbal instruction

Question 2

Neuroplasticity in the context of motor learning and neurological rehabilitation PRIMARILY refers to:

Accepted Answer

The brain's ability to reorganize its structure, function, and connectivity in response to experience and practice

Answer

The brain's capacity to generate new neurons (neurogenesis) in response to injury

Answer

The spontaneous recovery of damaged neural tissue following stroke within the first weeks

Answer

The flexibility of individual neurons to change their firing thresholds during movement

Question 3

The SAID principle (Specific Adaptation to Imposed Demands) as applied to neurological rehabilitation states that:

Accepted Answer

The nervous system adapts specifically to the type of demands imposed during practice, emphasizing task-specific training

Answer

Rehabilitation programs should always be adapted to the individual needs of each patient

Answer

Recovery of function follows a predictable and sequential developmental pattern in all patients

Answer

Rehabilitation demands should be systematically imposed from the most simple to the most complex

Question 4

Implicit motor learning is characterized by:

Accepted Answer

Skill acquisition that occurs without conscious awareness and cannot be fully verbalized

Answer

Learning driven by explicit verbal instruction and the conscious application of rules

Answer

Declarative memory for movement sequences that can be recalled and described accurately

Answer

Learning that relies heavily on hippocampal-dependent episodic memory systems

Question 5

Which of the following is the BEST example of augmented feedback in neurological motor rehabilitation?

Accepted Answer

Verbal cues from the therapist about the patient's trunk alignment during ambulation

Answer

Proprioceptive input from joint mechanoreceptors during a reaching task

Answer

Visual information about the position of objects in the environment during gait

Answer

Vestibular signals from the semicircular canals during balance training

Question 6

In Gentile's taxonomy of motor tasks, 'intertrial variability' refers to:

Accepted Answer

Changes in the regulatory conditions of the environment between practice trials of a task

Answer

Variability in patient performance across multiple treatment sessions over time

Answer

Variation in the type and frequency of augmented feedback provided by the therapist

Answer

Differences in patient motivation and effort from one practice trial to the next

Question 7

According to current motor learning principles, which combination of practice conditions MOST promotes generalization and transfer to novel functional tasks?

Accepted Answer

Variable practice across multiple contexts combined with random practice scheduling and faded feedback

Answer

Blocked practice in a single consistent environment with continuous augmented feedback throughout

Answer

Massed practice with minimal rest intervals to maximize total practice repetitions per session

Answer

Part-task practice with each movement component practiced to mastery before combining
