The basic articulations:
- Flexion and Extension
- Supination and Pronation
The Elbow CAR (controlled articular rotation):
- Take the arm along side the body and stabilize the humerus (upper arm)
- Fully lengthen the arm to find elbow extension at the end range.
- While at end range extension, rotate the forearm (radius) so the thumb of the hand is pointing towards the midline of the body for pronation.
- Maintain pronation and slowly take the elbow into flexion.
- While at end range flexion, rotate the forearm (radius) so the thumb of the hand is pointing away from the midline of the body to supinate the elbow joint.
- Maintain supination and move back into elbow extension.
- Rotate the forearm (radius) for pronation again and repeat.
- Avoid moving the humerus (upper arm)
- Always express current end ranges
- Repeat again or in the opposite direction if desired
