The extensor carpi radialis longus is a wrist extensor that is innervated by the radial nerve, [2] [3] from spinal roots C6 and C7. [4] All other major extensor muscles in the superficial layer of the posterior compartment (the extensor digitorum , extensor carpi radialis brevis , extensor carpi ulnaris , and extensor digiti minimi ) are ...
This study also suggests minimizing wrist extension through appropriate body posture at the workstation that may help to reduce carpal tunnel pressure. [30] A review of the literature has found evidence supporting the use of exercise and/or rest breaks in reducing musculoskeletal discomfort during computer work. [31]
It is an extensor, and an abductor of the hand at the wrist joint. That is, it serves to manipulate the wrist so that the fingers moves away from the palm. The muscle, like all extensors of the forearm, can be strengthened by exercise that resist its extension; Reverse wrist curls with dumbbells can be performed.

Exposure to wrist extension or flexion at work increases the risk of CTS by 2.0 times. [55] As of 2023 [update] , a systematic review of studies looking at the relationship between CTS and computer use has found current studies to be inconclusive and contradictory, due to poor study methods and confounding variables not being accounted for.
Wrist drop is a medical condition in which the wrist and the fingers cannot extend at the metacarpophalangeal joints. The wrist remains partially flexed due to an opposing action of flexor muscles of the forearm. As a result, the extensor muscles in the posterior compartment remain paralyzed.
The wrist curl is a weight training exercise for developing the wrist flexor muscles, the muscles in the front of the forearm. [1] It is therefore an isolation exercise. Ideally, it should be done in combination with the "reverse wrist curl" (also called wrist extension) which works out the muscles comprising the back of the forearms, [1] to ensure equal development of the wrist flexor and ...
