lsokinetic Evaluation of Tibial Rotation: Assessment of a Stabilization Technique*.
The purpose of this study was to present a wide range of normative data on maximum active tibial rotation utilizing isokinetic resistance and a relatively new stabilization technique. Both legs of 25 healthy adult male subjects were tested at 30, 60, 120, and 180 degrees per second of angular velocity. Data were collected on total range of motion, component internal/external range of motion (via two different methods), joint position at peak torque production, peak torque production, and torque production as a percentage of body weight. The effect of weight and leg length on peak torque production and total range of motion was also determined. In light of recent studies which have shown the need for specific rotational rehabilitation for rotatory knee instabilities, this study serves to present normative data for practical use in either the clinical or research setting.
