Abstract:
1. A method of measuring a person's joint performance and simultaneously measuring sincerity of effort comprising: providing a movable member to be moved by a single movement of one or more joints of the person; rapidly varying the resistance to movement of the member at least once during the single movement; measuring the force applied to the moveable member by the person during at least the single movement, recording the resistance applied to the movable member; inputting the resistance applied and the measured force applied into a means for calculating the correlation between the measured force applied to the movable member during the single movement and the resistance to movement of the movable member; and outputting a coefficient of correlation indicative of the correlation between the measured force applied to the movable member during the single movement and the resistance to movement of the movable member, wherein the coefficient of correlation provides an indication of the human's sincerity of effort in moving the movable member.
