Through years of testing we have discovered a unique posture for the fingers, thumb and palm that is not only great for rapid target acquisition, but also allows maximum muscle and tendon variation throughout point and click operations. Variation is only one of the keys. We also found that when the hand is placed in this balanced posture, local hand muscles come into play. This minimizes the need for flexor muscles that are connected to the fingers through the carpal tunnel. Reduction of carpal tunnel activity is the key to preventing carpal tunnel syndrome.
