Contraints on Motor control Learning Flashcards
Contraints on Motor control and Learning:
Neurological patients produce impaired movements and may not possess the motor skill necessary to produce corrective actions or to relearn coordinated movement
- Includes: abnormal synergies, decreased balance and postural control, decreased automatic function, impaired musculockeletal system ( complete or partial loss), fatigue, abnormal tone, hyperactive stretch reflexes, delayed motor learning (possibly absent), improper response to input due to poor feedback, profound cognitive deficits (i.e. TBI), and the CNS dysfunction may fail as a whole system resulting in insurmountable learning challenges
Motor skills
Can be termed as motor development, motor behavior that changes over time as a result of growth and experience
- Developmental motor skills or functional motor skills
- Speed-accuracy tradeoff
Developmental motor skills or functional motor skills
Permanent skills used throughout life based on 4 categories:
- Transitional mobility
- Static postural control
- Dynamic postural control
- Skill
Transitional mobility:
Ability to move from one posture to another, BOS and COM change i.e. supine to sit, transfers etc
Static postural control:
Ability to maintain postural stability and orientation with COM over the BOS having not body motion, BOS is fixed i.e. quadruped, half knelling etc
Dynamic postural control
Ability to maintain postural stability and orientation with COM over BOS while body parts are in motion i.e. wight shifting reaching for objects etc
Skill
Consistently perform coordinated UE and LE movement to gather info about the environment, during locomotion, COM is in motion and BOS is changing
Speed accuracy tradeoff:
Older adults exchange speed from improved accuracy
- Overall, movement is less efficient and more variable with age
- Motor units decrease in number and increase in size, results in poor coordination and decreased fine motor still.
