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).
In the hand, it innervates all the small muscles except for the thenar eminence and the first two lumbricals
With change in balance of power, the lumbrical
tends to pull the profundus distally as it shortens the lateral band.
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.
El nervio mediano inerva el oponente y el abductor corto del pulgar, el primer y segundo lumbrical
y parte del flexor corto del pulgar.
The American Society of Plastic and Reconstructive Surgeons recommends surgical release in the following situations (6): (1) failed or incomplete conservative therapy; (2) motor weakness or thenar atrophy; (3) lumbrical
pattern symptoms (occur when the metacarpophalangeal joints are held at 90 degrees, eg, driving, letter writing, holding a magazine, pinching, using a small tool); (4) severe pattern on electrical studies (not defined); (5) space-occupying lesions requiring excision; (6) acute carpal tunnel syndrome with symptoms lasting longer than 6 to 8 hours; and (7) progressive or severe symptoms lasting longer than 12 months.
The intrinsic muscles included the lumbrical
(LUM), palmar interosseus, and dorsal interosseus (INT).
These include segmental sensory conduction study across the carpal tunnel by median stimulation at midpalm, difference between the median motor latency to the second lumbrical
and the ulnar motor latency to the interossei muscles.

The lateral branch supplies the three thenar muscles and subdivides into proper palmar digital nerves supplying the lateral 1 and % fingers and the 1st lumbrical
