Accessory Movements Flashcards
What are you looking for with an accessory movement?
Pain, resistance or spasm in early, middle or late range
AP clavicle @ SCJ improves…
retraction and full ROM at GH joint
AP clavicle @ ACJ improves…
retraction and full ROM at GH joint
why do a AP clavicle at SCJ?
because clavicle glides posteriorly during retraction
and need full movement at pectoral girdle to allow full movement at GHJ
no concave convex rule
why do a AP clavicle at ACJ?
because clavicle glides posteriorly during retraction
and need full movement at pectoral girdle to allow full movement at GHJ
no concave convex rule
AP humerus improves…
GH flexion
Why does AP humerus improve GH flexion?
convex surface moving on a concave – so the movement of the lever is in the opposite movement to the glide
PA humerus improves
GH extension
Why does PA humerus improve GH extension?
convex surface moving on a concave – so the movement of the lever is in the opposite movement to the glide
Longitudinal glide GHJ improves…
abduction
Why does longitudinal glide improve GH abduction?
because in normal movement, HoH is pulled inferiorly by the rotator cuff to keep the joint stable. Concave convex still applies.
Lateral glide of humerus improves…
capsular stiffness
why does lateral glide of humerus improve capsular stiffness?
causes capsule to stretch into plastic range
Longitudinal glide of elbow improves…
elbow flexion
why does Longitudinal glide of elbow improve flexion?
concave surface moving on a convex – so the movement of the lever is in the same direction to the glide
