Choosing the Right Mouse

The average computer user reaches for the mouse multiple times each hour throughout the course of the day. Improper mouse positioning can lead to pain and even injury in the wrist and arm. Take the time to evaluate your mouse usage. These five guidelines can help protect you as you use your computer mouse.

1. Optimize your mouse location. This is one of the most important solutions for comfortable mouse use. When using a mouse, you need to sit in a natural position, with arms relaxed at your side and your mousing hand raised only slightly higher than your elbow. This placement normally requires a separate mouse platform. If using a flat platform, this will place the mouse approximately one to two inches above the number pad on a normal size keyboard. Using a downward sloping platform, place it to the side of your keyboard, as closely at it will fit. Never reach up to a desk or out to the side for your mouse.

2. Hold your mouse loosely in your hand. In addition to the correct position, remember to use a light touch with your mouse. Gripping too tightly will cause strain in your arm and hand.

3. Move your mouse from the elbow, not from the wrist. The wrist should be held in a straight line with your arm, minimizing wrist movement. Any bending of the wrist can trigger tendon damage. All mouse movement should require the movement of the entire lower arm, pivoting only at the elbow. Be sure you don't restrict arm movement through improper arm rests or hand pads.

4. Protect your wrists from surface pressure. Whether typing or using a mouse, your wrists need to remain free of surface contact pressure. Instead, the base of your palms should bear the weight of your hands to keep pressure off the carpal tunnel area in the wrist.

5. Consider the shape of your mouse. A mouse that properly fits your hand can reduce wrist extension. Take the time to handle and use several different ergonomic mice. The best mouse size and shape for you is one that promotes good wrist position and encourages movement from the elbow.

The advances in ergonomics allow people to minimize the strain caused by extended computer use. As computer operation becomes more and more dependent on the mouse, users need to learn how to protect themselves from improper placement or posture. A good mouse will encourage correct posture and hand position, eliminating pressure to the wrist. Finding the best ergonomic ergonomic mouse for your hand shape and size can lower your risk of pain and injury.
