Mouse arm and repetitive strain injuries

Mouse arm is a condition caused by long-term work with a computer and a mouse.

What are mouse arm and repetitive strain injuries?

The concepts mouse arm and repetitive strain injuries cover any condition that can develop in connection with repeated movements, over-stretching, vibration, applied pressure, sedentary work or awkward working positions. Repeatedly straining the muscles, ligaments, tendons and nerves is the cause of many different conditions that affect the shoulders, arms, wrists and hands. When you work with a traditional computer mouse, you hold the forearm and wrist in a position that deviates from the norm. Adjusting your work posture as well as varying the type of mouse can minimise the discomfort in the mouse-using arm to some degree.
