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, 4.
Therefore, particularly in severe cases with CTS, motor axons innervating lumbrical muscles tend to be less traumatized.
The comparative evaluation of the recordings from the second lumbrical muscles for median distal motor latencies and ulnar distal motor latencies obtained from the interosseous muscles is another technique assessing the sensitivity of motor NCS.
There was weakness of the lumbrical muscles of all 4 fingers, as well as, of the abductor digiti minimi in his left hand.
Once past the metacarpophalangeal joint, the extensor tendon is divided into three bands, the central portion which receives some of the fibers from lumbrical muscles, that goes to insert on the proximal interphalangeal joint capsule at the base of the second phalanx.

In this study the effectiveness of motor imagery training in facilitating activation of the hand lumbrical muscles in post-stroke hemiparesis was explored.
Carpal tunnel syndrome due to gouty infiltration of lumbrical muscles and flexor tendon.
Furthermore, interosseous and lumbrical muscles contribute to metacarpophalangeal flexion (Landsmeer & Long, 1965), thus generating force not accounted for by electrodes placed on the forearm.
Wide resection of the tumor was accompanied by disarticulation of the carpometacarpal (CMC) joint, osteotomy of the proximal second metacarpal bone, disarticulation of the second metacarpophalangeal (MCP) joint, resection of the tendons and neurovascular bundles of the thumb and index finger, and resection of both the first dorsal interosseous and lumbrical muscles. Concurrently, the thumb was reconstructed by pollicization of the remaining index finger, and the skin defect was covered with a skin graft.
INTRODUCTION: The lumbrical muscle is so named because it resembles the shape, size and color of an earthworm.
