Ergonomic guidelines
Research suggests that physical discomfort and injury to nerves, tendons, and muscles may be related to repetitive motion, an improperly set up work area, incorrect body posture, and poor work habits.
To reduce the risk of injury, follow these precautions:
•Stand, stretch, and move around several times every hour.
•Switch hands while performing tasks. Use shortcut keys on the keyboard to avoid repetitive or awkward mouse movements.
•Relax your shoulders and keep your elbows at your sides.
•Adjust the keyboard’s position so that you don’t have to stretch to reach it.
•Adjust your position so that you don’t have to bend your wrists to type. Avoid placing your wrists on a sharp edge.
•If you feel discomfort or numbness in your hands, wrists, arms, shoulders, neck, or back while typing, consult a qualified medical professional.
