The ulnar muscles should not be examined in isolation from other muscles. In particular, several key muscles with C8/T1, lower-trunk, medial-cord innervation should be examined, especially the abductor pollicis brevis (a thenar muscle typically involved with carpal tunnel syndrome, the major compressive median nerve neuropathy) and the median-innervated long thumb and index finger flexors.
