ABSTRACT:
An apparatus and method of water therapy in which a person is buoyantly supported in a prone position on a top membrane of a waterbed mattress containing heated water. A water pump recirculates the water, which is drawn out of the mattress through outlets and associated piping and which is then reintroduced through inlets and associated piping as an array of water jets. Air is introduced by a valve in the water piping on the return side of the pump or by means of a separate air pump connected to air inlets leading into the mattress. Also disclosed are a distributor fitting for insertion into the mattress to mix air and water and a base and frame assembly for concealing the plumbing and air recirculation piping.
