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.
In the hand, it innervates the thenar eminence and the first two lumbrical muscles.
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.

DISCUSSION: Forty specimens were selected to study the lumbrical muscles in hand of its origin, insertion and innervation.
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.
The co-ordination of extension of the PIP with simultaneous flexion of the MCP is known to be underpinned by the action of the hand lumbrical muscles (4).
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.
