Unit 2/3 Flashcards
what is the Shumway-Cook and Woollacott motor control theory
movement is a product of the interaction among the individual, the task, and the environment
Individual constraints
Motor/ action systems
Sensory/ perceptual systems
Cognitive systems
Environmental constraints
Regulatory
Non-regulatory
Contributions to movement control
Individual constrains
Environmental constraints
Motor/ action systems
Neuromuscular and biomechanical systems
Sensory/ perceptual systems
Peripheral sensory mechanisms and higher level processing
Cognitive systems
Attention, problem solving, motivation and emotional aspects that underline intent
Ex: trying to get a highschooler to exercise but they’re distracted on their phone
regulatory environmental contraints
aspects of the environment that shape the movement itself. Movement must conform to regulatory features
non-regulatory environmental constraint
may affect performance, but movement does not have to conform (distracted)
ex: low lighting doesn’t change or affect the way you walk
Task attributes
Discrete vs continuous
Closed vs open
Stability vs mobility
Manipulation vs non manipulation tasks
Discrete
Have recognizable beginning and end
Continuous
The end point of the task is not an inherent characteristic to the task but is decided arbitrarily by the performer
Ex: walking, running
Closed Movement Task
Movement performed in relatively fixed/ predictable environments
Open Movement Task
requires performer to adapt movement strategies to constantly changing/ unpredictable environment
Stability Task
nonmoving base of support
ex: sitting in a chair
mobility
moving base of support
ex: walking- feet are your BOS and move while walking
manipulation
involves movement of the upper extremities
reflex theory
complex behavior explained through individual reflexes chained together
What are the theories of motor control
a group of abstract ideas about the control of movement
-reflex theory
-hierarchical theory
-motor programming theory
-systems theory
-ecological theory
hierarchical theory
organization control that is top down
motor programming theory
control is activated either by sensory stimulus OR central processing
systems theory
movement is the result of the dynamic interaction between the perception, cognition, and action systems
ecological theory
how actions are geared to the environment
