Abstract: A traction assembly for placing a human body in traction under the inclined weight of the body for medical or therapeutic reasons. The major trunk portion of the body is supported on a movable platform. The body extremities, including the head and the ankles, are fixed relative to a frame. The platform is movable relative to the frame under the influence of gravity when the frame is placed at an inclination. The degree of traction placed on the body is dependent upon the weight of the body and the inclination of the frame with respect to a horizontal orientation. The frame can be reciprocated between first and second positions to place the body in gentle oscillating traction.
