- abd/add: convex on concave
what motion to facil thumb flexion at 1st CMC?

ulnar dev
what motion to facil thumb ext at 1st CMC?

radial dev
what motion to facil thumb abd at 1st CMC?

dorsal glide
what motion to facil thumb add at 1st CMC?

volar glide
zero starting pos for hand

longitudinal axes thru metacarpals and adgacent phalanges are in a straight line
resting pos for hand

slight flexion in all joints
capsular pattern of hand

restricted in all dir, but moreso in flex
resting pos fo CMCs
- thumb midway btwn abd/add and flex/ext
- fingers midway btwn flex and ext
close packed pos for CMC jts
- thumb full opposition
- fingers full flexion
capsular pattern of CMC jts
- thumb: abd>ext
- fingers: equal limitation in all dir
MCP joint resting pos

slightly flexed
MCP close packed pos
- thumb: full opposition
- fingers: full flexion
- (same as at CMC jt)
MCP capsular pattern

flex>ext

slight flex
packed pos of IP jts

full ext
capsular pttern of IP jts

flex>ext
