Abstract: An apparatus for the practice of ambulation comprises a suspension member for suspending a patient, a weight sensor for detecting a weight applied to the suspension member, an air cylinder or motor for producing a predetermined suspension force to be conveyed to the suspension member, a horizontal arm for supporting the suspension member, and a rotation axle for rotating the horizontal arm and the suspension member so that the patient who is suspended by the suspension member can be trained in walking in accordance with a predetermined suspension force which is proportional to a weight detected by the weight sensor.
