In this case, in the seat 10, the rail coupling part 16 provided in the seat 10 is fitted into the rail 2 to perform rail motion. Of course, the seat 10 is paraplegic patients sit down. In case of paraplegic patients, it is impossible to push the seat 10 using the lower body so that the seat 10 is forced to move forward and backward by borrowing the power of the electric motor 3. During this process, the muscles of the lower body are contracted and relaxed repeatedly, which helps in rehabilitation.

Here, the seat 10 is connected to the front and rear movement by the electric motor 3 and the gear connection, etc., and various known methods are applicable.

In addition, the seat 10 is a seat of the user who is a paraplegic patient as shown in Figures 2a and 2b, the seat 10 is the seat 11, the hips of the user; and the user's movement It is configured to include; a backrest (12) hingedly connected to the pedestal 11 so as to freely adjust the inclination angle according to the state.
