Method and apparatus for inducing and detecting ankle torsion
A force applied to the foot of a patient causes the foot to rotate inwardly. After measuring the rotational displacement of the foot inwardly as the function of the applied force, the force is removed and the displacement of the foot is measured again. Next, a force is applied to the foot of the patient that causes the foot to rotate outwardly. After measuring the rotational displacement of the foot outwardly as a function of the applied force, the force is removed and the displacement of the foot is measured again. The displacements versus applied forces are plotted on a Cartesian coordinate system to produce a hysteresis curve. The data obtained and the hysteresis curve produced therefrom provides a quantitative measure of the motion quality and motion quantity of the foot and its corresponding ankle and is subject to detailed analytic and medical analysis.
