摘要:
Systems and methods for providing traction to the lower back, where in one embodiment, a lumbar traction device has a back support, a base and a movable support structure connected between the base and the underside of the back support. The support structure enables the back support to move with respect to the base. When a user lies on the lumbar traction device, the user's weight causes the back support to move with respect to the base to apply tension to the user's back. The back support may have two separate portions on which the upper and lower back rest. The two portions of the back support move in opposite directions to provide traction on the back.
