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

contraindications for mobilization (8)

active disease
infection
advanced osteoporosis
articular hypermobility
fracture
acute inflammation
muscle guarding
joint replacement
