How to Treat Forearm Fatigue From Using a Mouse
Computers are prevalent and people spend a lot of time typing and using a mouse. A computer mouse is operated by the flexor and extensor muscles in the forearm. Fatigue and pain are commonly caused by excessive use of these devices. Although a minimal amount of force is required, these muscles require endurance to perform small movements over a long period of time.

Choose a computer mouse that comfortably fits in the palm of your hand. A mouse that is too large or too small can cause muscles to fatigue more quickly.

Design an ergonomically correct workstation. Sit in an adjustable-height chair and place the computer mouse on a stable surface. Adjust the height of the chair, until your elbows are bent at approximately 90 degrees and wrists are in a neutral, straight position. Place the mouse next to the keyboard to minimize reaching.

Stretch your forearm muscles several times each day. Place your right arm straight out in front of you with your palm facing the ceiling. Take your left hand and gently bend the right wrist, so that your fingers are pointing toward the floor. Hold this stretch for 10 seconds. Turn your right arm over, so your palm is facing the floor. Use your left hand to bend your wrist, so that your fingers point toward the floor and hold this stretch for 10 seconds. Repeat on the left side.

Take a five minute break every hour during computer use, to allow the forearm muscles to rest. If possible, rotate job activities, so that computer work is alternated with other tasks.
