Chapter 1: Issues and Theories Flashcards
Why should therapists study motor control?
Because we retrain patients who have motor control problems producing functional movement disorders
What is motor control?
The ability to regulate or direct the mechanisms essential to movement
What are the three factors that interact to produce movement?
Task, individual, environment.
What are the three factors within an individual that constrain movement?
Cognition, action, and perception
What is the degree of freedom problem?
The problem of choosing amongst the multiple number of ways that an action can be carried out.
What is perception when it comes to the individual?
The integration of sensory impressions into psychologically meaningful information. Includes:
(1) peripheral sensory mechanisms
(2) higher level processing that adds interpretations and meaning to incoming afferent information
What is cognition when it comes to the individual?
A broad processes that include attention, planning, problem solving, motivation, and emotional aspects of motor control that underlie the establishment of intent or goals
What are the three groupings of task constraints of movement?
Stability, mobility and manipulation
What is a discrete task?
A task that has a recognizable beginning and end. Example: kicking a ball
What is a continuous task?
A task that has a cyclical pattern (walking)
What is a stability task?
A task that has a stationary base of support.
What is a mobility task?
A task in which the base of support is in motion
How do you define a manipulation task?
A task that increases the demand for stability beyond that demanded for the same task lacking the manipulation component.
What is an open movement task?
A task that requires the performer to adapt their behavior within a constantly changing and often unpredictable environment
What is a closed movement task?
Tasks that show little variation and are performed in a relatively fixed or predictable environment.
