Motor Learning, Neuroplasticity, and Rehabilitation Strategies in Physical Therapy

What is Motor Learning Theory?

A set of internal processes associated with practice or experience leading to relatively permanent changes in the capability for motor skill.

How is motor learning inferred?

It is inferred from changes in motor behavior over time.

What are neuroplastic changes?

Changes in the brain due to exercise, including synaptic modification, dendritic branching, and formation of neural connections.

What role does Brain-Derived Neurotrophic Factor (BDNF) play in exercise?

BDNF supports neuroplasticity, learning, and memory; it is increased by exercise and decreased by stress.

How does exercise affect the sensorimotor system?

Exercise improves sensorimotor integration, reflex activity, postural responses, coordination, and timing.

What are the cardiovascular effects of exercise?

Exercise improves oxygen consumption (VO₂), cardiac output, and oxygen extraction at the muscle.

What secondary impairments can exercise help prevent?

Muscle atrophy, contractures, cardiovascular deconditioning, and reduced oxidative capacity.

How can exercise regulate muscle tone?

Exercise can facilitate activation in low-tone presentations and inhibit excessive tone through weight bearing, repetitive movement, and sensory input.

What factors enhance motor learning capacity through exercise?

Ability to process feedback, adjust movement strategies, and refine motor performance, dependent on repetition and task-specific practice.

What is the goal of motor learning progressions?

To promote motor learning rather than just performance.

What is the difference between recovery and compensation in motor learning?

Recovery involves using the affected side more and increasing task difficulty, while compensation involves using the stronger side and modifying the environment.

What is massed practice?

A practice strategy where practice time is greater than rest time.

What is distributed practice?

A practice strategy where practice time is less than or equal to rest time.

What is constant practice?

A practice strategy where the task is practiced the same way each time with minimal variability.

What is variable practice?

A practice strategy where the task is practiced with variations in performance.

What is blocked practice?

A practice strategy where a task is practiced repeatedly before moving onto another task (AAABBBCCC).

What is random practice?

A practice strategy where several different tasks are performed in a random, unpredictable order.

What is concurrent feedback?

Feedback given during task performance, often related to knowledge of performance (KP).

What is terminal feedback?

Feedback given at the end of task performance, which can be knowledge of performance (KP) or knowledge of results (KR).

What is bandwidth feedback?

Feedback given only if performance falls outside a predetermined error range.

What is faded feedback?

Feedback given less frequently with ongoing practice.

What is the purpose of summary feedback?

Feedback provided after a set number of trials to summarize performance.

What is intrinsic feedback?

Individual's own sensory information, such as proprioceptive, visual, vestibular, auditory, and cutaneous signals.

What is extrinsic (augmented) feedback?

Supplemental information provided by a therapist that enhances intrinsic feedback, including verbal, visual, and tactile cues.

What does Knowledge of Performance (KP) focus on?

It focuses on the quality of movement, providing feedback like 'Lean forward more' or 'Shift your weight left.'

What does Knowledge of Results (KR) focus on?

It focuses on the outcome of the movement, such as 'You stood up successfully,' promoting motor learning.

What is visual feedback?

Using visual input to guide movement, such as mirror feedback or watching limb movement.

What is manual (tactile) feedback?

Hands-on input from a therapist, such as guiding trunk alignment or providing resistance.

What are the types of external feedback?

Includes verbal, visual, and manual (tactile) cues that supplement intrinsic feedback.

What is the purpose of task-oriented intervention?

To match the intervention to the patient's goals, ensuring it is repetitive, active, meaningful, and variable.

What is the progression in feedback scheduling?

It involves transitioning from constant feedback to faded feedback, and from immediate to delayed feedback.

What is the key clinical goal in rehabilitation?

To maintain movement quality and safety while providing enough intensity for functional improvement.

What does the ICF model assess?

It assesses body structure/function, activity performance, participation, personal factors, and environmental factors.

What are examples of physiological impairments in the ICF model?

Decreased strength, increased tone, poor coordination, decreased proprioception, visual deficits, and decreased endurance.

What activities might a patient struggle with according to the ICF model?

Bed mobility, sitting balance, scooting, transfers, sit-to-stand, and walking.

What are personal factors that can affect performance?

Age, motivation, cognition, beliefs, and fatigue.

What are environmental factors that influence performance?

Home setup, support system, assistive devices (AD), and obstacles.

What is the role of feedback in motor learning?

Feedback promotes motor learning by providing information on performance and results.

What is forced use of the involved limb?

A treatment approach known as Constraint-Induced Movement Therapy (CIMT) that encourages use of the affected limb.

What is neurofacilitation?

A treatment approach that includes sensory stimulation techniques like tapping and weight bearing.

What is the significance of variable practice in rehabilitation?

It improves carryover of skills to real-life situations.

What are some examples of static sitting activities in rehabilitation?

Sitting balance while reaching for objects or performing activities of daily living (ADLs) like brushing teeth.

What does the term 'dynamic sitting' refer to?

Activities that involve reaching outside the base of support (BOS) and weight shifting.

To ensure exercise is task-specific, repetitive, and intense while monitoring vital signs and patient tolerance.
