Abstract
The purpose of this investigation was to determine the validity and reliability of a new attachment designed to facilitate the measurement of bilateral contractions using a Kin-Com isokinetic dynamometer. Through a series of experiments the Kin-Com and attachment were tested for efficacy of lever-arm movement velocity and force measurements for both unilateral and bilateral conditions. Valid measurements were obtained for unilateral and bilateral force application, as well as lever-arm movement time and velocity. Practical implications of this experiment include the ability to obtain bilateral and unilateral measurements with one attachment without having to change the test set-up for each limb, thereby decreasing the time spent in patient set-up. Additionally, a practitioner or researcher could assess function of bilateral limb movements and make comparisons to unilateral movements. These comparisons can be used to measure the bilateral deficit that can be increased or decreased with resistance training to suit the needs of the individual.
