TI For Motor Control- Stability (2) Flashcards
What is motor control?
Neural regulation of motor behavior
What is motor control stability?
Allows joint to be stable when movement is not supposed to occur
What is joint stability?
Dynamic interactions of all muscles that surround target joint and gravitational forces to produce motor control stability
Where can damage be to effect stability?
Primary motor cortex
Cerebellum
Basal ganglia
Sensory input from vestibular system
Stability
Co contraction of agonists and antagonists (weight bearing)
How does resistance exercise help with stability?
Build activation and possible irradiation of activation
How does weight bearing/closed chain activities help with stability?
Approximation and increased activation
How does postural exercise help with stability?
Strengthens core muscles (focuses on extensors and co contraction)
How does biofeedback/e stim help with stability?
Motor learning and increases activation
How does tapping/strapping and splinting/bracing help with stability?
Decreases degrees of freedom
How do pressure garments help with stability?
Provide approximation and sensory stimulation
How does body weight supported treadmill training help with stability?
Decreases degrees of freedom and decreases task difficulty
What are the advantages of closed chain exercises in increasing stability?
Approximation and limits degrees of freedom (more functional)
What are the advantages of open chain exercises in increasing stability?
Focuses more on just strengthening
What are the reasons to put patients in a lot of different positions to work on stability?
Each position can increase or decrease degrees of freedom
Each position activates different muscles
