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.
It is widely claimed that an ergonomic keyboard may reduce muscle strain and reduce risk of carpal tunnel syndrome or other kinds of repetitive strain injury. [ 4 ] [ 27 ] [ 28 ] [ 29 ] With respect to "split" keyboards, quality studies that demonstrate injury reductions are lacking, with the exception of physically split keyboards which have ...
The use of a keyboard may cause serious injury (such as carpal tunnel syndrome or other repetitive strain injuries) to the hands, wrists, arms, neck or back. [19] The risks of injuries can be reduced by taking frequent short breaks to get up and walk around a couple of times every hour.

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 ...
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]
The use of any keyboard may cause serious injury (that is, carpal tunnel syndrome or other repetitive strain injury) to hands, wrists, arms, neck or back. [47] The risks of injuries can be reduced by taking frequent short breaks to get up and walk around a couple of times every hour.
A repetitive strain injury (RSI) is an injury to part of the musculoskeletal or nervous system caused by repetitive use, vibrations, compression or long periods in a fixed position. [1] Other common names include repetitive stress injury , repetitive stress disorders , cumulative trauma disorders ( CTDs ), and overuse syndrome .
