Abstract
An apparatus operable in cooperation with a bed having a top surface and opposite head and foot ends for applying traction to a patient's lower back, including a lower sheet extending from the head end lengthwise to the foot end, said sheet including excess length at the head end of said bed, pulling means for pulling said lower sheet lengthwise toward the foot end of said bed, and an upper sheet having one end fixedly attached to said head end of said bed and extending lengthwise about halfway to said foot end, said upper sheet positioned above and lying on said lower sheet said pulling means adapted to periodically pull said lower sheet lengthwise in the foot end direction a predetermined distance, wherein movement of the lower sheet with the patient's buttocks and legs lying thereon effects a frictional pull in the foot end direction on said buttocks and legs, and wherein the weight of the patient's upper body on the fixed upper sheet effects a frictional resistance in the opposite direction on the patient's upper body, thus producing a tension in said lower sheet and a traction to the patient's lower back intermediate said upper body and buttocks.
