Abstract: During rehabilitation of extensor mechanism dysfunction, a successful transition from isometrics to isokinetics is essential. As discussed in the literature, previous protocols made a direct transition from isometrics to isokinetics or isotonics. An alternative route may be taken with the patient by placing him or her on the isotonic mode of the Kinetic Communicator. The isotonic mode is a transitional step in the rehabilitation protocol which offers several advantages such as freely accelerating and decelerating movement, slower speeds, and the ability to be able to progress speed and force. The isotonic mode uses a patient feedback system joined with preset eccentric and concentric force settings to develop increased quadriceps control. The protocol can be gradually progressed with patient tolerance, and increased speeds can be attained to make an easy transition to higher-speed isokinetics. The isotonic mode is most successful with tension and friction type injuries, as presented in two case studies.
