The accessory tendon attached to the base of the first metatarsal, and a tendinous slip inserted into the neighboring dorsal interosseous muscle
. Tendinous slips may also extend to the base of the third, fourth or fifth metatarsals, or the adductor hallucis muscle (Standring).
Manual muscle testing (MMT) at the initial examination revealed the following muscle strengths on the left side: deltoid, 0; biceps brachii, 0; triceps brachii, 2; wrist flexor muscles, 3; wrist extensor muscles, 3; lumbrical muscles of the hand, 4; and interosseous muscle
Superficial recording electrodes were placed over APB (at 8 cm distance from the stimulus site), second lumbrical muscle (at 10 cm distance from stimulus site), and second interosseous muscle
(at 10 cm distance from stimulus site).
Preoperative electromyography of the flexor carpi ulnaris, abductor digiti minimi, and first interosseous muscle
was done in all patients.
There have been reports that interosseous muscle
atrophy results from the pain caused by MCPJ involvement, reflex inhibition after the pain, and non-use of the hand.

As it runs through the anatomic snuffbox, it enters the palm between the two heads of the first dorsal interosseous muscle
and then between the heads of the adductor pollicis muscle dividing into the princeps pollicis artery and the deep palmar arch.

(1975) investigated the discharge rates of the first dorsal interosseous muscle
and found that synchronisation was greater in weightlifters than control participants.
