Incorrect computer usage may lead to carpal tunnel syndrome, tendonitis, tenosynovitis 
or other musculoskeletal disorders. The following symptoms may appear in the hands, 
wrists, arms, shoulders, neck or back:

•    numbness, or a burning or tingling sensation

•    aching, soreness or tenderness

•    pain, swelling or throbbing

•    stiffness or tightness

•    coldness or weakness

If you have these symptoms, or any other recurring or persistent discomfort and/or pain 
related to computer use, consult a physician immediately and inform your company’s 
health and safety department.

The following section provides tips for more comfortable computer use.
