Abstract
The effect of gravity should be considered when using isokinetic devices to measure human movement performance. In most isokinetic dynamometers gravity compensation is controlled by software through a gravity correction option. However in some complex research protocols the dynamometer signal acquisition and processing capability is not adequate to effectively synchronize or process a wide range of captured signals. Therefore when the force/torque signals from a commonly used dynamometer such as KIN-COM® are interfaced into a signal processing workstation such as AMLAB®, it is necessary to further process the received raw signals for gravity correction. The aim of this study was to evaluate the effectiveness of an AMLAB®-based instrument designed for gravity compensation of raw torque signals acquired from a KIN-COM® dynamometer. To check the accuracy of weight compensation within the AMLAB® environment, torque signals produced by a known weight during a 180-degree range of KIN-COM® lever arm movement were compared with and without weight compensation. The results indicated that this technique is an accurate means for weight compensation when raw torque signals from a KIN-COM® dynamometer are interfaced to an AMLAB® workstation.
