If there is evidence of moderate or severe ulnar neuropathy, or the patient has bilateral symptoms, or the referring physician requested both hands, perform on the contralateral side the following: the ulnar (s), dorsal ulnar (s) and ulnar (m) to ADM and 1st DI with f-waves.
Needle Examination
Perform needle exam on the symptomatic limb. Test the minimum of one muscle innervated by the C5, C6, C7, C8 and T1 spinal roots as well as the FDI, ADM and the ulnar nerve innervated forearm muscles. If the ulnar innervated muscles are abnormal, the examination should include non ulnar C8/medial cord/lower trunk muscles, to exclude brachial plexopathy and cervical paraspinals to exclude radiculopathy.
