The medical problem associated with computer-related work is carpal tunnel syndrome (CTS). CTS is a stress-related injury caused by repetitive movement of joints, especially the wrist, and can lead to numerous musculoskeletal problems.
For example, Keir et al. suggest breaking up the repetitive action of using a computer mouse with other tasks because mouse use was shown to increase carpal tunnel pressure. This study also suggests minimizing wrist extension through appropriate body posture at the workstation that may help to reduce carpal tunnel pressure. [30]
RSIs are assessed using a number of objective clinical measures. These include effort-based tests such as grip and pinch strength, diagnostic tests such as Finkelstein's test for De Quervain's tendinitis, Phalen's contortion, Tinel's percussion for carpal tunnel syndrome, and nerve conduction velocity tests that show nerve compression in the wrist.
In general, ergonomic keyboards are designed to keep the user's arms and wrists in a near-neutral position, which means the slant angle (the lateral rotation angle for the keys in each half relative to the axis of the home row in a conventional keyboard) is approximately 10 to 12.5°, the slope (the angle of the keytop surfaces starting from the front edge closer to the user towards the top of ...
Carpal tunnel syndrome (CTS) is a nerve compression syndrome associated with the collected signs and symptoms of compression of the median nerve at the carpal tunnel in the wrist. Carpal tunnel syndrome usually has no known cause, but there are environmental and medical risk factors associated with the condition. [1] [6] CTS can affect both wrists.

A computer mouse (plural mice, also mouses) [nb 1] is a hand-held pointing device that detects two-dimensional motion relative to a surface
A mouse and mousepad. A mousepad or mousemat is a surface for placing and moving a computer mouse.A mousepad enhances the usability of the mouse compared to using a mouse directly on a table by providing a surface to allow it to measure movement accurately and without jitter.
Advocates of endoscopic carpal tunnel release cite less palmar scarring and ulnar “pillar” pain, rapid and complete return of strength, and return to work and activities at least 2 weeks sooner than for open release. Some studies comparing open and endoscopic carpal tunnel release found no significant differences in function.
