The best remedy for a pointing device injury is rest. Take breaks every 15-20 minutes and change position frequently when working. Make sure that your pointing device is positioned correctly. Your pointer should be at the same level of your keyboard and within easy reach. This level should allow you to work with your arms close by your sides, your elbow at approximately 100 to 110 degree angle, and your wrists in a straight or neutral position.
Wide keyboards result in the pointer being positioned further out to the side.
A mouse bridge can be used to position your mouse or trackball closer to you if you do not need to use your keypad. Some users have found that switching the pointing device from the right side to the left side of the keyboard allows them to use it with their arm in a more relaxed position. This allows them to place the device closer to their center front by avoiding positioning to the outside of the keypad on the right. Give yourself time to get used to switching hands. If you use a mouse and are experiencing shoulder pain, try switching to a trackball.
