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
AP radius @ superior RU J improves…
elbow extension
why does AP radius @ superior RU J improve extension?
concave surface moving on a convex – so the movement of the lever is in the same direction to the glide
AP radius @ inferior RU J improves…
supination
AP radius @ inferior RU J improves supination because…
convex surface moving on a concave – so the movement of the lever is in the opposite movement to the glide
PA radius @ inferior RU J improves….
pronation
PA radius @ inferior RU J improves pronation because…
convex surface moving on a concave – so the movement of the lever is in the opposite movement to the glide
AP radoiocarpal improves… & why?
Wrist flexion - convex surface moving on a concave – so the movement of the lever is in the opposite movement to the glide
PA radoiocarpal improves… & why?
Wrist extension - convex surface moving on a concave – so the movement of the lever is in the opposite movement to the glide
Lateral glide RCJ improves… & why?
Ulnar Deviation - convex surface moving on a concave – so the movement of the lever is in the opposite movement to the glide
Medial glide RCJ improves… & why?
Radial Deviation - convex surface moving on a concave – so the movement of the lever is in the opposite movement to the glide
AP mid carpal improves… & why?
Wrist flexion - convex surface moving on a concave – so the movement of the lever is in the opposite movement to the glide
PA mid carpal improves… & why?
Wrist extension - convex surface moving on a concave – so the movement of the lever is in the opposite movement to the glide
AP MCP improves… & why?
Finger extension – convex surface moving on a concave – so the movement of the lever is in the opposite movement to the glide
PA MCP improves… & why?
Finger flexion – convex surface moving on a concave – so the movement of the lever is in the opposite movement to the glide
AP CMC improves… & why?
CMC Extension. Moving concave surface on convex so movement of joint is in same direction as lever arm.
PA CMC improves… & why?
CMC Flexion. Moving concave surface on convex so movement of joint is in same direction as lever arm.
A/P distal phalanx @ interphalangeal joint improves… & why?
Finger extension – convex surface moving on a concave – so the movement of the lever is in the opposite movement to the glide
PA distal phalanx @ interphalangeal joint improves… & why?
Finger flexion – convex surface moving on a concave – so the movement of the lever is in the opposite movement to the glide
