2 Neuroplasticity and Motor Learning Flashcards
1
Q
Denervation hypersensitivity
A
-increase in receptors on post-synaptic neuron due to destruction of pre-synapatic neuron
2
Q
Synaptic hypereffectiveness
A
-increased NT release in available pre-synaptic axon terminals after damage resulting in increased stimulation of post-synaptic receptors
3
Q
Principles of neuroplasticity
A
- use it or lose it
- use it and improve it
- specificity matters
- repetition matters
- intensity matters
- time matters
- salience matters
- age matters
- transference
- interference
4
Q
Cognitive/novice stage of learning
A
- learner- high performance variability, requires cognition and attention, many errors
- therapist- physical guidance, cues, closed environment, encourage massed/blocked practice, frequent feedback
5
Q
Associative/advanced stage of learning
A
- learner- knows effective way to complete tasks but may make subtle adjustments, addition of degrees of freedom with less co-contractions, able to self-correct
- therapist- random practice, open environment, fading feedback
6
Q
Autonomous/expert stage of learning
A
- learner- can perform in all situations/environments, less attention to detail, efficient
- therapist- open environment, random practice, summative or bandwidth feedback
7
Q
Pre-participation requirements of learning
A
- be alert
- have adequate attention
- possess motivation
- demonstrate capacity for memory
8
Q
Practice type
A
- part- for serial tasks
- whole- for continuous and discrete tasks
9
Q
Amount of practice
A
- distributed- rest more than practice, for continuous tasks
- massed- practice more than rest, for discrete tasks, task novelty
10
Q
Intrinsic vs extrinsic feedback
A
- intrinsic- proprioceptive, kinesthetic, tactile, visual, auditory cues. During or directly after task completion. Cerebellum, BG, SMA, PMA
- extrinsic- in addition to internal feedback. Therapist cueing or mechanical source. Medial temporal lobe areas
