There is a lot of debate regarding the use of wrist rests
for computer users who perform intensive keying for extended periods. Contact between the
wrists and wrist rests of any design if too frequent or heavy can cause problems due to
excessive pressure on the delicate tendons on the underside of the wrist, and has been
known to result in Carpel Tunnel Syndrome and tenosynovitis (inflammation of the sheath
surrounding tendons). This may be what has led people to believe that wrist rests should
not be used. In general, wrist rest should be used only for resting the wrist when not
keying. If wrist rest is used on the workstation , then it should:
- allow the wrists to be in a neutral position and not bending
up or down.
- have a thickness about the same as the front of the keyboard
or the mouse.
- not have sharp edges and be padded and provide stable
support.
