DPT 5000 Quiz 2- Motor Control Flashcards
What is motor control?
- ABILITY TO REGULATE OR DIRECT THE MECHANISMS ESSENTIAL TO MOVEMENT.
- Neural, physical, and behavioral aspects of movement.
- Study of how and individual controls movement already acquired.
Motor control addresses what questions?
- How does CNS coordinate muscle and joint movement?
- How is sensory info from the environment and body used to direct body movement?
- How can mvmnt problems be identified, categorized, and diagnosed in patients with motor control problems?
Why study motor control?
PTs are “movement specialists”!
What you understand about MC & where it works will drive what kind of intervention you will use.
Nature of Movement
(Remember illustration of the 3 circles)
Task
Individual
Environment
All overlap and this overlap is Movement
Individual Factors of Movement
- Perception
- Cognition
- Action (motor)
Perception
The integration of sensory info into meaningful biologically relevant information (site, hearing touch, etc.)
Can be Regulatory or Adaptive
Regulatory vs. Adaptive perception
Regulatory- shaping ongoing movement
(changing our movement to what we see)
Adaptive- influencing future movement
(making adjustments based on what you view from previous movement)
Cognition
The ability to process, sort, retrieve, and manipulate info.
Includes: attention, alertness, selectivity, effort, motivation, memory, emotional aspects.
Book def: attn, planning, problem solving, motivation, and emotional aspects.
Types of attention
- Sustained attn: ability to maintain attn over time
- Selective attn: ability to decide what you pay attn to.
- Alternating attn: ability to switch tasks.
- Divided attn: pay attn to multiple things @ one time.
Action
Neuromuscular control–> motor output
Coordinated control of muscles an joints during execution of a function movement.
Relationship between Cognition, Perception, and Action and Body Systems
Continuum:
- Sensing
- Perceiving
- Interpreting
- Conceptualization
- Strategy/ Plan
- Activation
- Execution
Task Considerations:
Stability vs. Mobility
Stability- non-moving base of support
i.e. Sitting or Standing
Mobility/Transport- moving base of support
i.e. walking or running
Task Considerations:
Manipulations continuum
Ranges from none, simple, to complex
Environmental Constraints:
Regulatory vs. Non-regulatory
Regulatory Conditions- aspects of environment to which movement must conform (shapes the movement). People, objects, etc.
Non-regulatory Conditions- aspects that may interfere with successful movement but do not constrain. i.e. noise, distractions, lighting.
Regulatory Conditions
Stationary vs. in Motion
Regulatory-Stationary: i.e. moving from sit to stand in a classroom chair. Chair height is stationary but you must adapt to it.
Regulatory-Motion: i.e. moving from sit to standoff a Swiss ball. Ball is moving and you must adapt to that while completing the task.
