osteokinematic and arthrokinematic joint motions

### sternoclavicular

elevation/depression --

convex: clavicle

concave: sternum

[opposite direction]

protraction/retraction --

convex: sternum

concave: clavicle

[same direction]

### proximal radioulnar (similar to proximal tibiofibular)

convex: radius

concave: ulna

[opposite direction]

### prox and distal IP joints of digits 2-5

convex: the more proximal phalange

concave: the more distal phalange

[same direction]

### proximal tibiofibular (similar to proximal radioulnar)

convex: tibia

concave: fibula

[same direction]

### distal tibiofibular (similar to distal radioulnar)

convex: fibula

concave: tibia

[opposite direction]

### subtalar

(anterior and middle sections)

convex: talus

convex: calcaneus

[same direction]

(posterior sections) -- where calcaneus is rounded

convex: calcaneus

concave: talus

[opposite direction]

### IP joints of toes

convex: the more proximal phalange

concave: the more distal phalange

[same direction]

convex-concave rule:

with convex on concave, roll and glide occur in the ________ direction.

convex-concave rule:

- with CONVEX on concave, roll and glide occur in the OPPOSITE direction

- mobilizing force should be applied in the opposite direction of bone movement

###
convex-concave rule:

with concave on convex, roll and glide occur in the ________ direction

convex-concave rule:

- with CONCAVE on convex, roll and glide occur in the SAME direction

- mobilizing force should be applied in the same direction of bone movement

### indications for mobilization (3)

restricted joint mobility

restricted accessory motion

desired neurophysiological effects
