The most important ulnar hand muscles to test are the first dorsal interosseous muscle and the abductor digiti minimi (abductor digiti quinti). In the forearm, the flexor digitorum profundus of the fourth and fifth digits (which flexes the distal phalanges of those fingers) and the flexor carpi ulnaris (which controls flexion at the wrist in the ulnar direction) are valuable to examine.
