Spinal Root: C5

Muscles Innervated:
    Supraspinatus *
    Infraspinatous *
    Rhomboids
    biceps brachii *
    brachioradialis *
    deltoid   *
    extensor carpi radialis longus *

* Please note, that these muscles along cannot differentiate a C5 radiculopathy from a C6 radiculopathy. We are unsure if this is true of the Rhomboids as well.
