A CAT for the mouse

Repetitive strain injury (RSI) is a common affliction amongst computer users that spend long hours in front of the computer. Pain in the wrists, hands and shoulders are not uncommon symptoms and if left untreated may result in serious ligament and muscular injury. Prevention is the better method of cure in these cases and with this in mind, a German inventor has designed CAT, an ergonomic lever that supports the wrist.
A CAT for the mouse
Potential sufferers from Repetitive Strain Injury (RSI) are offered an ergonomic product that may provide prevention which in this case is far more important than cure. RSI can effectively injure and permanently disable workers that are subject to repetitive tasks if proper precautions are not taken into consideration.

CAT, the name given to the design that provides ergonomic support to computer users consists of three simplistic parts. The base, placed on the floor, the stem which is inserted into the base, and the rest pad, which supports the wrist. It has been designed to support the wrist of computer users when working at the computer for extended periods of time. Because of its swivel-spring loaded design, the CAT allows the freedom of movement needed when operating the mouse and/or key pad, whilst simultaneously providing support for the limb and hence considerably reducing the risk of RSI.

CAT offers an annoyance-free concept that imparts total manoeuvrability to users and is as such, a viable form of support for those users that utilize programs requiring accurate movement of either mouse or graphic pen such as CAD designers. The CAT is also adjustable, having a telescopic shaft that can be changed in length to fit comfortably with people of all sizes thus maximizing its effectiveness in preventing RSI. Additionally, the CAT system may be used for both arms providing the computer user with absolute comfort.

As a sign of this simple innovation's significance, it has been awarded the silver medal in the International Geneva Inventor's Exhibition in 1999
