Interventions to Improve Motor Control and Motor Learning Flashcards
Objectives
Compare and contrast theories of motor control, motor learning and common principles of therapeutic interventions.
Identify the purposes and components of a motor control assessment
Define: spasticity, clonus, decerebrate rigidity, decorticate rigidity and flaccidity
Identify common causes of motor control impairments (discussed last lecture & throughout course)
fyi
- Components discussed previously (various components of a PT examination)
- An assessment of impairments, activity limitations and functional restrictions
- Plan of care is formulated
- is often the basis of the POC
- breaking a task into subtasks; an activity down into components
Activity-based, task-oriented intervention
- Deals with “the understanding of neural, physical and behavioral aspects of movement.” And….
- Processing of human motor behavior:
- Stimulus identification
- Response selection stage: develop a plan for movement
Motor Control
* Plan for purposeful movement- MOTOR PLAN
- Made up of components
- A prototype is chosen
- Choose what fits the situation best
ex: log rolling -using the strategy of something you’ve done before and your body remembers.
Response Selection Stage
neural control centers translate the idea for movement into actionmotor program
All steps occur very quickly
Response programming
- “Abstract representation that, when initiated, results in production of a coordinated movement sequence.”
- Considers synergistic component parts
- Force
- Direction
- Timing
- Duration
- Extent of movement
- Feedforward and Feedback
Motor Program
- “Internal processes associated with practice or experience leading to relatively permanent changes in the capability for skilled behavior.”
- Don’t observe change in CNS directly, but will see change in motor behavior
- Practice: determines improvements in performance
- Learning: does not always occur when increase in performance is observed.
Motor Learning
Motor Learning Retention
apply a learned skill to learning of a similar skill (i.e. transfer to multiple surfaces)
Generalizability
Demonstrate the skill that has been learned over time, after no recent practice (retention interval) - no recent practice and can still do it.
Motor Learning Retention
Motor Learning Retention
ability to perform a measured task in altered environmental situations (i.e. walking with a cane inside/ walking outside) -really just change the environment.
Resistance to contextual change
Stages of Motor Learning
develop understanding of the skill- what stage?
Cognitive
Stages of Motor Learning
- What do I need to do?
- How do I do it well?
- Uses sensory motor skills, discard strategies that you don’t find useful
- When learning, rely heavily on vision
cognitive map
Stages of Motor Learning
- Middle state of learning
- Refine motor practice through continued learning
- Proprioception is very important
what stage ?
Associative
Stages of Motor Learning
- largely autonomic response from repeating the skill many times
- Minimal cognitive monitoring
what stage?
Autonomous
Not Ready for Task-Oriented Training???
- P14- box 2.2
- Identifying threshold abilities is important to ensure that interventions will be successful and beneficial
built from the basics-
if no trunk controll you can’t work on standing. start with trunk contol first and work from there
