Why The Mouse Causes RSI and How Keyboard Shortcuts Can Help

Why that pesky mouse causes so much trouble ...

"For several reasons, the mouse is the worst offender when it comes to computing injury. Repetitive Strain Injury occurs as a result of the cummulative effect of seemingly small actions carried out over a long period of time, eventually leading to unbearable strain on the muscles.

Many people develop RSI in their mouse hand. The mouse causes the extensors to tighten in order to hold the fingers slightly above the mouse buttons. The slight but constant tension causes a cummulative injury effect. The constant movement back and forth from the mouse to the keyboard can also lead to severe elbow pain. The position of dorsiflexion (holding the mouse with your wrist bent upwards) is another cause of RSI."    (Continued via The Ergonomenon)    [Ergonomics Resources]
