1

What is a motor program?

An abstract representation that when initiated results in the production of a coordinated movement sequence.

E.g.—CPGs that control locomotion and gait

2

What is a motor plan?

An idea or plan for purposeful movement that is made up of several component motor programs

3

Describe motor memory

(Procedural memory)

Involves the recal of motor programs or subroutines and includes information on:

(1) initial movement conditions
(2) how the movement is felt, looked, sounded
(3) specific movement parameters (KP)
(4) outcome of the movement (KR)

4

Describe systems theory.

Cooperative actions of multiple systems allow for accommodation of movement ot match the specific demands of the task and the environment

5

What is the central concept of systems theory?

Many systems (e.g. CP, MS, endocrine, cognition) interact to produce coordinated movement, not just the nervous system

6

Motor learning is defined as?

A set of internal processes associated with practice or experience leading to relatively permanent changes in the capability for skilled behavior

7

Feedback

Response-produced information received during or after the movement and is used to monitor output for corrective actions

8

Feedforward

The sending of signals in advance of movement to ready teh sensorimotor systems

Allows for anticipatory adjustments in postural activity

9

T of F: Processing of information by the CNS is both parallel and serial leading to the production of coordination

True

10

Coordination

The ability to execute smooth, accurate and controlled motor responses

11

Coordinative structures (synergistic units)

Are the functionally specific units of muscles that are constrained by the NS to act cooperatively to produce relatively stable movment patterns but are scaled to the environment

12

Recovery of function

Reacquisition of movement skills lost through injury

movements recovered may be performed exactly as before

For neurologically impaired pts a determination then needs to be made as to whether the movements are of sufficient quality and efficiently to permit return of function (e.g.—pt with stroke learns to dress using the involved UE)

13

Compensation

Adoption of alternative behavioral strategies to complete a task

(Movmement utilizes different muscles and strategies to sub stud for the loss of function)

E.g. pt with stroke dresses using the less involved side UE

14

Neuroplasticity

The ability of the brain to change and repair itself

Includes a continuum from short-term changes in the efficiency or strength of synaptic connection to long-term structural changes in the organization and numbers of connections among neurons.
