M. Extensor Carpi Radialis Longus
Literature
- Position
- 30% on line from lateral epicondyle to Proc. styloideus radii
- Orientation
- Parallel to the radius
- Signal check
- Wrist extension and radial deviation.
- Crosstalk from
- brachioradialis · extensor digitorum
- MVC test
- Seated or kneeling in front of a bench with the forearm resting on a stable support.
- Fixation
- Forearm fully supported; wrist free to work against the resistance.
- Resistance
- Manual resistance, a barbell or a cable/belt against the wrist or hand.
