1
Q
Equilibrium Rxns/Tilting Rxns
What are they?
A
- Complex feedback, postural rxns
- Elicited by unexpected mvmt of the body’s COM that perturbs balance and stims vestibular system
2
Q
Equilibrium Rxns/Tilting Rxns
- Complex feedback, postural rxns elicited by unexpected mvmt of the body’s COM that perturbs balance and stims vestibular system
- Stim vs. Response
A
-
Stimulus:
- Displace COM in relation to BOS or by moving supporting surface
-
Response:
- Curvature of trunk w/ EXT and ABDuction of extremities ON side to which force is applied
