Abstract
Abstract A hydrotherapy apparatus includes a frame mounted on caster rollers and carrying a subject-supporting platform has drain openings and raised side borders with longitudinal slots. Springcounterbalanced housings containing distributor manifolds are vertically movable through the slots between raised and retracted positions and have discharge openings in their inner walls. Nozzles are supported by the manifolds in registry with the discharge openings. A crank-operated mechanism effects the raising and lowering of the housings. An extension tray is located at an end of the platform and is movable between retracted and extended positions.
