Computerized exercise, physical therapy, or rehabilitation apparatus with improved features

摘要

A computerized exercise, physical therapy, or rehabilitation apparatus with improved features. The computerized exercise apparatus permits concentric and eccentric isokinetic exercise by a user where apparatus calibration is accurately determined before exercise to compensate for the user selected force application device, the push assembly, if used, and environmental factors; where hydraulic flow can be accurately controlled by use of an alternating current dither circuit; where multiple user force application devices, a push assembly, and a detachably connectable operator support are available for a myriad of exercises; and where the instantaneous forces measured during user exercise are displayed to the user in such a novel way so as to motivate the user to maximize their exercise efforts and thereby obtain increased personal benefit.
