Evaluation of a Dynamometer for Measurement of Isometric and Isokinetic Torques
A modified version of the original Cybex II dynamometer with a temperature compensated strain gauge transducer has been evaluated. It was found that the calibration constant was dependent of the vertical load of the device. The ratio (k) between the applied and the recorded torque is angle independent during extension and k is equal to 1.18 and during flexion k is angle dependent and can be expressed as k = −.0008 θ + 1.208, where θ is the angle of flexion.
