Wrist Analysis
The top three ergonomic errors that put the hurt into work:
1. 89% of people hold the mouse wrong
Ergonomic error: bending your wrist while clutching the mouse and holding your arm too far away from your body.
Fix it: keep your wrist straight and grip the mouse gently. Hold your arm close, with your elbow bent 90 degrees.

2. 88% of people have poor typing technique
Ergonomic error: pressing your wrists on the wrist rest and striking the keys with too much force.
Fix it: reach the keys by moving your arms instead of stretching your fingers or bending your wrists. Type quietly to reduce finger force.

3. 84% of people set their keyboard wrong
Ergonomic error: setting your keyboard too high.
Fix it: set your keyboard tray at elbow height. If the keyboard is on your desk, adjust your chair so your elbows are even with the top of your desk.
