Your hands - together with your wrists - help you do a remarkable variety of tasks. From playing the piano to cooking dinner or hammering a nail, your hands respond daily to various commands that ask for feats of strength and dexterity. To put it simply, your hands are literally extensions of your brain. More of your brain is reserved for controlling hand movements then for controlling any other part of your body. You use your hands all day, everyday, both at home and at work. Yet in doing all of these things that they do everyday, your hands and wrists are prone to accidents and injuries.
