The hook serves as a site of attachment of several structures including the flexor digiti
minimi, opponens digiti
minimi, pisiohamate ligaments, and distal portion of the transverse carpal ligament.
1% amplitude reduction of the fifth compound muscle action potential compared with the first during a train of supramaximal nerve stimulations at 3 Hz in the left abductor digiti
minimi and right deltoid strongly suggests dysfunction of the NMJ.
1314 The deep motor branch of the ulnar nerve then innervates the hypothenar muscles (abductor digiti
minimi, flexor digiti
minimi, and opponens digiti
minimi), lumbricale muscles to D4 and D5, and the ulnar intrinsics including the dorsal and palmar interassei and adductor pollicis.

There was weakness of the lumbrical muscles of all 4 fingers, as well as, of the abductor digiti
minimi in his left hand.

In the repetitive stimulation of the abductor digiti
minimi, a continuous pathological decrement was noted with a stimulation frequency of 3 Hz, while a 300% increase in amplitude was found at 50 Hz for 4 s (Figure 1).

The following muscles and functions were tested when possible, and an average integer was reported per patient for hand and/or foot function: hand grip, opponens pollicis (opposes thumb), abductor pollicis brevis (abducts the thumb), adductor pollicis (adducts the thumb), opponens digiti
minimi (opposes the little finger), abductor digiti
minimi (abducts the little finger), third palmar interossei (adducts the little finger), foot dorsiflexion and plantar flexion.
