A traction device utilizes a harness connected to the body of a patient, such as the head or hips. The harness is connected by a clip to a tether which passes through a ratchet pulley connected to a first end of a spring chamber. A second end of the spring chamber is connected to a support. As tension is applied to the tether, the ratchet pulley incrementally applies traction to the patient as a first spring housed within the spring chamber deflects with the application of force.
