What is RSI?
In simple medical terms R.S.I. (repetitive strain injury) is defined as a cumulative trauma disorder stemming from prolonged repetitive, forceful or awkward hand movements. we add to that poor posture and positioning of an out-of-shape worker, ill fitting furniture, and a badly designed keyboard. R.S.I. is part of the ‘Work Related Upper Limb Disorder’ (WRULD) family of conditions.
Causes of RSI
Fine hand movements, repeated hour after hour, day after day, thousands upon thousands of times, eventually strain the muscles and tendons of the forearms, wrists and fingers causing small tears. Injured muscles tend to contract, decreasing the range of motion necessary for stress-free work. The sheaths that cover delicate tendons run out of lubrication because they are not given time to rest, so the insulted tissues become painful.
Symptoms of RSI
- Stiffness, tingling, coldness, numbness or burning in the hands, wrists, fingers, forearms or elbows.
- Clumsiness or loss of strength and coordination in the hands.
- Pain that wakes you up at night and feeling a need to massage your hands, wrists, and arms.
Preventing RSI.
- Keep your wrists straight, in a neutral position.
- Use your whole arm and shoulder to move the mouse, not just the wrist.
Mouse Use Tips
- Mice should be held loosely. Imagine you are holding a small bird. You may not realise it, but gripping creates tension in the other fingers.
- Do not use the mouse for more than 45 minutes at a time. Set an alarm to remind you to take ‘mini breaks’.
- Use the desk for forearm support - allow at least 2-3 inches from edge of desk.
- Keep the mouse positioned within forearm reach. If the cord is not long enough, buy a cable extension or use a cordless type.
- Use a MouseBean®!
