Ergonomic Mouse

There are several different methods by which a normal mouse can become an ergonomic mouse. Keeping the unit below desk level will lower the chances of developing carpal tunnel syndrome and will help to keep the shoulder joint at a relaxed position. Also, placing it within the horizontal Neutral Reach Zone (the area easily reachable by the hand while the upper arm neutrally hangs by the side) will minimize flexion and abduction of the shoulder and wrist joints.

A larger mouse, compared to one that fits easily within the palm of the hand, can do a lot of harm and can flex the hand beyond the comfortable point. Past mouse designs practically force the user to madly grip the sides of the unit with the thumb and little finger. These disastrous designs can cause undue strain and pressure within the hand and wrist bones, tendons and muscles.

A truly ergonomic mouse is meant to be utilized symmetrically and can be switched from one hand to another at any sign of discomfort. It is thus important to include space on either side of the keyboard for the mouse, or to have a keyboard holder that includes an adjustable side mouse rest. Some ergonomic mice include contoured palm rests and can be adjusted to a number of different hand sizes.

When to Buy an Ergonomic Mouse

Ideally, an ergonomic mouse should be purchased the first time a computer area is set up. However, one should be bought at the first sign of stress to the tendonous structures of the hand and wrist. If you observe poor practices in a fellow employee (including improper extension and flexion in the wrist), you may want to consider purchasing an ergonomic mouse tool for him at the earliest moment possible.
