It supplies sensation to the dorsoulnar aspect of the wrist and hand and to the dorsal surface of the last two digits.

Since unreliable, uncooperative, or disoriented patients may render the physical examination results inaccurate or equivocal, a more objective means of validating the aforementioned clinical sign is desirable. Jabre⁵ recently reported a method measuring nerve conduction in the dorsal cutaneous ulnar nerve that accomplishes this purpose. Concurrently we developed a similar technique, and . . .
