Motor control/learning

Question 1

A patient that has learned the ability to transfer from bed to wheelchair, but is unable to transfer bed to toilet or standard chair is said to have what poor quality?

Answer 1

poor generalizability

Question 2

What is feedforward?

Answer 2

anticipatory responses that adjust the system for incoming sensory feedback or future movements
- ie. preparatory postural movements prior to throwing a ball

Question 3

What is augmented feedback?

Answer 3

extrinsic feedback

- verbal cuing, for example

Question 4

Discuss massed practice vs blocked practice.

Answer 4

blocked practice = doing a single motor skill repeatedly

massed practice = relatively continuous practice, where rest time is small

Question 5

What is the opposite of massed practice?

Answer 5

distributed practice = rest time relatively large (larger than practice time)

Question 6

What are the phases of learning?

Answer 6

cognitive phase
associative phase
automatic phase

Question 7

When in training is it more appropriate to rely on proprioceptive feedback for motor learning?

Answer 7

associative phase

• visual feedback better in cognitive phase

Question 8

T/F: Feedback after every trial improves performance during early learning.

Answer 8

true

Question 9

Compare random practice vs serial practice.

Answer 9

random practice = doing variety of skills in no predictable order

serial practice = doing variety of skills in same, predictable order
