Abstract
A method and device for self-applying natural traction to the lower spinal region with an elongate generally vertical frame contoured to fit the backrest portion of a furniture piece having a seat, the frame having an upwardly extending portion with a pulley system mounted thereon at a substantial level above the backrest. A cable is trained around the pulley system and a removable belt attached to one end of the cable is adapted to be secured around the lower thoracic region of the user. The other end of the cable is free and is passed through a releasable gripper device mounted on the frame to hang therebelow. The frame is first placed on the backrest of the furniture piece such that the pulley system and free end of the cable overlie the seat. Then a seated position in the chair is taken and the belt is snugly secured around the lower thoracic area of the body. By grasping the free end of the cable and pulling it downwardly, the buttocks are raised vertically such that the weight of the body is substantially wholly supported by the belt and the forces of gravity apply a natural traction to the lower spinal vertebra.
