Mod 1 Intro to Motor Control Flashcards
What is motor control?
ability to regulate or direct the mechanisms essential to movement
Why should PTs study motor control?
- PTs = applied motor control physiologists
- understanding motor control and the nature and control of normal and abnormal movement is critical to clinical practice
What is the model for motor control?
- movement emerges from factors of individual, task, and environment
What are the factors of individuals factors of movement?
- cognition system
- action system
- perception system
What is the motor/action system factor of individual factor of movement?
- neuromuscular and biomechanics systems
What is the sensory/perception factor of individual factor of movement?
- integration of sensory signals and meaningful info
- includes peripheral sensory mechanisms and higher-level processing that adds interpretation and meaning to incoming afferent info
What is the cognition factor in the individual factor of movement?
intentions or goals
How does task impact movement?
type of tasks performed greatly impacts neural organization of the movement
What are the 3 factors of task factor in movement?
- postural control
- mobility
- upper extremity function
How can you classify task constraints/attributes?
- discrete vs continuous vs sequential
- closed vs open
- stability vs mobility
- manipulation vs non-manipulation tasks
What does task classification allow for?
development of taxonomy of tasks
What is an example of a task being performed in a closed, predictable environment with stability ?
- sitting or standing on nonmoving surface
What is an example of a task being performed in a closed, predictable environment with mobility?
walking on non moving surface
What is an example of a task being performed on an open, unpredictable environment with stability?
sitting or standing on foam or rocker board
What is an example of a task being performed in an open, unpredictable environment with mobility?
walking on uneven or moving surface
