Abstract: There is disclosed herein a method for quantifying a user's motor skills. The method comprises the steps of voluntarily moving a motion sensing member for at least a part of one cycle, the cycle comprising movement in a first direction and a return direction, measuring at least one of regularity of the movement of the member and mean angular velocity of the member. The method may be performed simultaneously with two members. Further, the members may be actuated by various body parts including a finger, a hand, or a shoulder. The data generated by the movement of the motion sensor may be stored as modulated carrier frequency in order to perform the method in locations remote from laboratories or computing facilities.
