prevent loss. 

 
 

Medical 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 bad work habits. 
To reduce the risk of discomfort and injury, follow the precautions below: 

 

Stand, stretch, and move around several times every hour. 

 

Switch hands while performing tasks. Use shortcut keys to avoid repetitive or awkward mouse 
movements. 

 

Relax your shoulders and keep your elbows at your sides.  Adjust the position of the keyboard 
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 experience continual discomfort or numbness in your hands, wrists, arms, shoulders, neck or back 
while typing, you are advised to consult a qualified medical professional.
