<p>A hydrotherapy method and apparatus (100) for discharging water stream through a rigid conduit (130) while concurrently translating the conduit discharge orifice along a nonlinear path (114) describing an area. The conduit (130) is comprised of a supply section (132) and discharge section (136) having an axis misaligned with the supply section axis for discharging a stream in a direction tending to rotate the conduit (130) around the supply section axis. Frictional loading of the conduit (130), attributable to suction produced by the supply water jet (151), is mitigated by providing a passageway which permits the suction to draw tub water (120) into a cavity (154) for entrainment by the water jet (151) for discharge through the conduit (130).</p> |
