Managing your Muscles
Moving a Mouse
Cup your hand, gently, so as not to over work the PALMARIS LONGUS MUSCLE, around the mouse and completely relax your fingers and whole arm. The mouse should be smaller than your hand, and quite low. It should be just big enough so that the weight of palm rests on the mouse, with the middle finger resting on the mouse buttons. The buttons should not be so sensitive that resting on them causes them to depress. The mouse should be moved using the weight of the palm. Don't actually "hold" onto the mouse with fingers, especially avoid holding with the thumb and little finger. Ideally you should relax the fingers such that the thumb and little finger aren't even touching the sides of the mouse. This position allows you to "hold" the mouse without stagnant muscle tension, simply by the weight of the hand.
Move the mouse from the shoulder and elbow, not the wrist. This approach ensures that you use the large fatigue resistant muscles in your shoulders and upper arm, instead of the tiny muscles in your hand or forearm. This method takes some practice and may feel difficult at first. Patience.... Patience.....so you don't become a patient!
