Isokinetic principle and its clinical application in orthopaedic rehabilitation

Isokinetic training, as a technique of orthopaedic rehabilitation, is a new and valuable method in evaluation of muscle function and in training muscle strength. It has higher accuracy and reproducibility in evaluation of muscle function. When isokinetic training of muscle strength is done, kinetic velocity is fixed beforehand in the dynamic instrument so that the resistance matches the actual force applied by the individual. The resistance maintains the maximum throughout the range of motion and produces the greatest muscle strength. As a result, the isokinetic muscle strength is effective and safe in the orthopaedic rehabilitation.
