Abstract: A physical-rehabilitation and exercise apparatus designed to aid in rehabilitating disabled individuals, particularly stroke victims who have been partially paralyzed. The apparatus is defined by a frame structure having an adjustable seat which incorporates individually operable right and left arm-control actuators, and right and left leg-control actuators. The arm-control actuators together with the leg-control actuators are adjustably slidable so as to provide a reciprocal longitudinal action which is determined by the proper selection of valves within a hydraulic system that includes a plurality of cylinders, each being integrally formed as part of the respective arm and leg control actuators, whereby a series of sequential operations can be selected by the user to provide the necessary movement for exercising the disabled limb or limbs.
