ABSTRACT
Isokinetic dynamometry is used extensively for rehabilitation and the assessment of muscle strength by measuring joint moment during constant angular velocity isolated joint movements. Isokinetic dynamometers are electromechanical devices that control angular velocity and are fitted with torque transducers but it is important to understand their operating principles for the accurate assessment of joint moment. This chapter explains the biomechanical basis of isokinetic dynamometry and the main factors that affect the measurements including joint and dynamometer axes alignment and subject positioning. Recommendations for appropriate experimental procedures, data collection and processing techniques and reporting of an isokinetic study are also included.
