To miniaturize the device, facilitate the carrying, make the device attachable to a bed, and perform a rehabilitation without worrying about the circumstances by a method wherein the other end of a belt wherein an operation ring is provided at one end, and a dog is provided in the vicinity of the other end in a manner to leave an attaching location, is fixed to a take-up pulley, and a rewinding is started when the dog location is detected.
For example, a foot 11 which is an affected part, is engaged with an operation ring 2, and a rehabilitation range of the foot 11, e.g. a vertical movement width L is determined. Then, a dog 4 is fixed onto a belt 3 at a location which is away from a sensor 9 by a dimension L. A switch is turned on under a state wherein the foot 11 is naturally placed on a bedding, and a motor 8 is turned, and the belt 3 is taken up. Thus, the foot 11 is lifted, and when the foot 11 is lifted by the dimension L, the dog 4 is detected by the sensor 9. By the detection, the motor 8 reverses, and the belt 3 is rewound, and the foot 11 returns on the bedding. Thus, the device is made compact, can be used while being attached to a bed, and the carrying is facilitated as well.
