- Flexion - Decreases joint
- Extension - increase joint angle
- hyperextension- excessive extension beyond normal range
Rotation: Turning of bone around its own axis. Rotates to and from medial point.

- Lateral Rotation - Away form Midline
Special Movements: Most are specific to actual joints and there directions.
