Abstract: Disclosed is an orthopedic apparatus for effecting the manipulatively equivalent treatment of disorders of the skeletal system by using one's weight to stretch one's body. It comprises: a base having a rotary axle provided therewith; a body bearing board responsive to rotation of the rotary axle for inclining about the rotary axle, thereby raising or lowering one or the other end of the body bearing board; and a console for determining an oblique angle at which the body bearing board is inclined, selecting which direction the body bearing board is inclined, clockwise or counterclockwise, the length of time for which the body bearing board is kept inclined and determining other variables in operation. The body bearing board comprises a leg shaking section for holding the opposite legs of one's body and for shaking them horizontally, a longitudinal, parallel arrangement of rotatable rolls and a head holding section for holding the head of the patient lying on the body bearing board.
