Neck pain| wrist dorsiflexion
Patients with neck pain may present with wrist symptoms and have difficulty with making a fist and picking the wrist up so that the back of the wrist is toward the face. This may be related to pain, spasm or tightness of the muscles that perform this movement.
The main muscles that perform wrist extension (dorsiflexion) are:
- extensor carpi radialis longus supplied by the radial nerve (C5, C6)
- extensor carpi radialis brevis supplied by the posterior interosseous branch of the radial nerve (C6, C7)
- extensor carpi ulnaris supplied by the posterior interosseous branch of the radial nerve (C7, C8)
- extensor digitorum supplied by the posterior interosseous branch of the radial nerve (C7, C8)
