The MouseBean Hand Rest elevates the forearm to maintain a straight wrist. This reduces stress on the tendons where they run through the carpal tunnel. Overuse of the hand and fingers when the wrist is bent can lead to tenosynovitis (inflammation of the covering of the tendons), a painful condition affecting the forearm. Resting the forearm on the desktop can become increasingly uncomfortable. This mouse Hand Rest protects the delicate median nerve that runs through the carpal tunnel in the wrist. It does this by preventing the central part of the wrist from being pressed against a hard surface. The MouseBean Hand Rest supports the hand on the soft fleshy parts either side of the median nerve.
The MouseBean Hand Rest reduces tension and stress in the hand, arm, shoulder, neck and back. Because the heel of the hand is properly supported, the arm does not need to be elevated to move the mouse and this encourages upper arm mobility. Supporting the hand in this way also seems to reduce the need to grip the mouse too tightly. Constant tension in the forearm is a common cause of tenderness and burning sensations.
Psychological stress induced by pain due to bad posture and other factors, is an important issue in the workplace and the MouseBean Hand Rest can help to break the pain/stress cycle. The MouseBean Hand Rest allows the wrist to rotate into a comfortable position and can be used on either hand. The gently rounded base allows it to slide on and off the edge of a mousemat without snagging.
