ABSTRACT:
An isokinetic exercise and monitoring machine for use in exercising and evaluating an individual's back muscles. A preferred embodiment (10) comprises a restraining means (33) for sandwiching the lower body half that is adjustably connected to a support frame (16); a restraining means (17) for sandwiching the upper body half, including means for pivoting the upper body restraining means (17) about the lower body restraining means (33) in response to the individual's movement generated by extension and flexion of his back muscles; a spring-loaded stop to prevent overtravel and excessive deceleration of the second restraining means (17) at the end of its rotational movement; means for vertically adjusting a platform upon which the individual stands so that the restraining means (17) and (33) engage his body appropriately; and wheels (57) and (58) attached to a support frame (16) to provide portability of the machine (10). The lever arm (13) of a dynamometer (11) attaches to a central point of the upper body restraining means (17) to prevent twisting of the lever arm (13) and problems caused thereby.
