They keep the arm in an unnatural pronounced state – causing the bones in the forearm to twist and place pressure on nerves and muscles in the arm, wrist and hand. Rtotating your hand flat with a regular mouse causes you to internally rotate your shoulder, increasing the tension there. Also keeping your hand constantly resting on the underside of the wrist places unnecessary stress and pressure on muscles and nerves which can lead to; Repetitive Strain Injuries Carpel Tunnel Syndrome Posture problems Neck and Shoulder pain and even trigger head aches! The VertErgo™ mouse keeps the arm in a neutral, relaxed position allowing free blood flow and not causing any discomfort. You will notice the difference immediately!
