Posture Control Flashcards
System approach - repsonse to perturbations
Tilted on unstable surface
Direction specific response
Fine tuning
System approach - postural strategies
Ankle, hip, stepping strategies
System approach - musculoskeletal
UE rom - protective responses
LE ROM - postural strategies
Strength to resist gravity and enviro perturbations
Vertical righting reaction
Orient head to vertical in various positions
- tilting from upright suspended
- prone as part of landau
- supine w/ chin tuck
- sidelying
Rotational righting
Restore body parts to normal alignment following rotation of some body segment
Protective reactions forward
(6-7mo)
move toward floor head first - arms ext and ab
Equilibrium reaction
Observe counter movements of head, neck, trunk or extremities when COM is displaced
Generally opposite to the opposing force
Protective reaction lateral
6-11
displaced from sitting
Protective reaction backward
9-12 mo
