Motor Control And Motor Learning Flashcards
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
What is a motor plan?
An idea or plan for purposeful movement that is made up of several component motor programs
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)
Describe systems theory.
Cooperative actions of multiple systems allow for accommodation of movement ot match the specific demands of the task and the environment
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
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
Feedback
Response-produced information received during or after the movement and is used to monitor output for corrective actions
Feedforward
The sending of signals in advance of movement to ready teh sensorimotor systems
Allows for anticipatory adjustments in postural activity
T of F: Processing of information by the CNS is both parallel and serial leading to the production of coordination
True
Coordination
The ability to execute smooth, accurate and controlled motor responses
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
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)
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
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.
