ABSTRACT:
An apparatus for effecting spinal traction on a patient includes a tub containing liquid in which a patient, buoyantly supported by a floatation device, can float in a generally upright position in a state of buoyant equilibrium. The level of the liquid in the tub can be varied, which effects a variation on a traction force acting on the patient as the floatation device seeks new positions of buoyant equilibrium in response to the change in liquid level. The traction force may be generated by one or more weighted devices worn on the body of the patient or by a harness attached to the patient and secured within the tub to resist upward movement of the patient when the liquid level rises in the tub. The liquid level within the tub is varied by a liquid level varying apparatus associated with the tub which operates generally by displacing a volume of liquid within the tub to vary the level of the liquid by an amount corresponding to the volume of displaced liquid. A method for effecting spinal traction includes floating a patient in a vessel of water, applying a body-tensioning force to the patient's body, and raising and lowering the level of liquid in the vessel to effect variations in the body-tensioning force as the patient's floating body seeks a new position of buoyant equilibrium.
