Study Notes

Fatigue and Learning

Fatigue can hinder learning, particularly with massed practice schedules.
Boring massed practice may lead to reduced cognitive effort from learners, negatively affecting learning outcomes.
Shorter, more frequent practice sessions are associated with better skill acquisition and retention.
Distributed practice over several days enhances long-term memory consolidation.

Optimal Practice Environment

An effective rehabilitation training environment should be stimulating and challenging to promote engagement.
Environments should replicate real-world tasks or situations to ensure relevance to everyday activities.
Structured training setups can allow for safe and independent practice, facilitating learner success.

Novice Learner Setup

Environment tailored for novice learners aids in task success, especially with conditions like abnormal joint contours or congenital disorders.
Factors affecting success may include joint laxity, reduced muscle length, and conditions like contractures arising from inactivity or injury.

Decreased Muscle Strength

Muscle strength reduction affects the ability to meet gait demands, leading to abnormal walking patterns.
Causes of decreased strength include:
- Disuse muscle atrophy due to immobilization or inactivity (e.g., quadriceps weakness post-surgery).
- Neurological impairments from central nervous system lesions (e.g., CVA, SCI, TBI), resulting in muscle weakness or spasticity.

Altered Muscle Coordination

Coordination issues manifest as problems with selecting, timing, and sequencing muscle activity or force production.

Impact of Pain on Gait

Pain can alter gait patterns through:
- Restricted range of motion (ROM) due to protective posturing, limiting necessary movement for normal gait sequences.
- Changes in muscle activity, leading to inhibition or overactivity of muscles, potentially resulting in muscle imbalances and disuse atrophy over time.

Cognitive Processing and Exercise

Effects of exercise are specific to the task and context, influenced by:
- Joint angles during activity.
- Muscle length and contraction type.
- Velocity of muscle contractions and body posture (e.g., non-weight bearing vs. full weight bearing).

Practice Intensity

Repetition is crucial for motor learning, raising the question of optimal practice intensity to achieve effective learning outcomes.
