1

Define Motor Control.

The study of the nature of movement; or the ability to regulate or direct essential movement

Historically though to arise from reflex or hierarchical models where the cortex was perceived as the highest functioning component of the system and spinal level reflexes were the lowest functioning components

2

Name a few of the motor control theories.

1. Reflex theory
2. Hierarchical theory
3. Motor programming theory
4. Task-oriented theory
5. Ecological theory

3

Define Motor Learning.

Study of the acquisition or modification of movement.

4

What does Motor Learning differentiate?

Differentiates learning vs performance, provides guidelines for appropriate use of feedback, prioritizes the impact of practice as it relates to skill and movement, and also focuses on the transfer of learning across tasks and environments of practice.

5

What are the two initial theories of motor learning?

1. Adam’s closed loop theory

2. Schmidt’s schema theory

6

What is Adam’s closed loop theory?

-First attempt at the creation of a comprehensive motor learning theory with the precise of sensory feedback as an ongoing processes for the nervous system to compare current movements w/stored information on memory of past movement

-high emphasis on the concept of practice

7

What is Schmidt’s schema theory?

- response to the limitations of the closed loop theory

-Main construct relies on open loop control processes and a motor program concept

-promotes clinical value of FB and importance of variation with practice

8

What are the 3 stages in the 3 stage model of motor learning?

1. Cognitive stage

2. Associative stage

3. Autonomous Stage

9

Describe the cognitive stage.

-initial stage of learning where there is a high concentration of conscious processing of information

10

What will a person acquire during the cognitive stage?

Acquire information regarding the goal

11

What is the ideal environment for a person in the cognitive stage of learning?

controlled environment

12

What are the characteristics of the cognitive stage?

-large amount of errors
-inconsistent attempts
-repetition of effort allows for improvement in strategies
-inconsistent performance
-high degree of cognitive work; listening, observing and processing FB

13

Describe the associative stage of learning.

-intermediate stage of learning where a person is able to more independently distinguish correct vs incorrect performance

14

What is the person doing during the associative stage?

The person is linking the FB that has been received with the movement that has been performed and the ultimate goal

15

What environment should the person be in during the associative learning phase?

-A controlled environment is helpful but at this stage the person can progress to a less structured or more open environment

16

What should be avoided during the associative stage of learning?

Avoid excessive external FB as the person should have improved internal or proprioceptive FB for the task at hand

17

What are the characteristics of the Associative stage of learning?

-decreased errors with new skill performance
-decreased need for concentration and cognition regarding the activity
-skill refinement
-increased coordination of movement
-large amount of practice yields refinement of the motor program surrounding the activity

18

Describe the autonomous stage of learning

-the final stage of learning or skilled learning where a person improves the efficiency of the activity without a great need for cognitive control

19

What environment is a person in the autonomous stage of learning able to perform in?

Person in this stage of learning is able to perform the task with interference from a variable environment

20

What is the autonomous stage characterized by?

1. automatic response
-mainly error-free regardless of the environment
-patterns of movement are non-cognitive and automatic
-distraction does not impact the activity
-the person can simultaneously perform more than one task If needed
-extrinsic Feedback should be very limited or should not be provided
-internal feedback or self-assessment should be dominant

21

Why is feedback important?

-It is imperative for the progression of motor learning.

-Allows for correction and adaptation within the environment

-Pts will rely on both intrinsic and extrinsic feedback

22

What does current research support in regards to extrinsic feedback ?

Research supports reducing the extrinsic feedback (fading of feedback) in order to ultimately enhance learning

23

List the types of feedback

1. Intrinsic (inherent) FB
2. Extrinsic (augmented) FB
3. Knowledge of results (KR)
4. Knowledge of performance (KP)

24

Describe Intrinsic (inherent) FB.

-represents all FB that comes to the person through sensory systems as a result of the movement.

-Includes: visual, vestibular, proprioceptive, and somatosensory inputs

25

Describe extrinsic (augmented) FB.

-represents the information that can be provided while a task or movement is in progress or subsequent to the movement

-typically in the form of verbal FB or manual contacts

26

Describe KR.

-important form of extrinsic FB

-includes: terminal FB regarding the outcome of a movement that has been performed in relation to the movement’s goals

27

Describe KP

Extrinsic FB that relates to the actual movement pattern that someone used to achieve their goal of movement

28

In NeuroRehab what does practice refer to?

Repeated performance of an activity in order to learn or perfect a skill

29

What does practice allow?

Allows for direct physical experience and kinesthetic stimulation to assist with acquisition of the skill

30

What is mental practice?

Cognitive rehearsal of a task or experience without any physical movement
