Abstract
An active human limb manipulation device utilizes a frame to which a carriage is slidably mounted for vertical movement. A sub-carriage is movably mounted to the carriage for horizontal movement and carries the limb of a patient along a predetermined path. Both carriage and sub-carriage are powered by a pair of rodless cylinders which are controlled by a computer control system which simulates normal walking movement so as to strengthen and stretch the limbs of a patient who otherwise lacks the strength and muscle tone associated with normal limb movement. The cylinders have yokes which are fixed to the carriage and sub-carriage and retained in position on the cylinders by a magnetic attraction. When the patient's resistance to movement reaches a predetermined level, the yoke will break the magnetic bonds with the cylinder piston so as to avoid overstressing the limbs of the patient. The yoke may be supplied with an electromagnet so that the magnetic attraction can be closely controlled.
