Abstract: A simple and easy-to-use therapeutic device comprises a pair of spaced arm supports for supporting the arms of the patient. The patient pushes the arms laterally against the arm supports to self-stabilize the shoulder girdle complex and horizontally load the sternoclavicular joints. Controlled movements of the head, neck, shoulder, and/or hip are made effective to create self-participatory healing of various portions of the spinal column by inducing synovial lubrication of the vertebrae. The patient's body can be positioned in different postures for isolating different parts of the spinal column for re-education, including a sitting position on a chair, a kneeling position, and a saddle position on a saddle seat. A head rest prevents or minimizes compensations by the body, and further isolates the movements of the body to promote more effective re-education of specific portions of the spinal column. The device is simple in structure and easy to manufacture.
