A flexible mat having a plurality of protruding members and a plurality of apertures is agitated by pressure pulsation in a stream of highly turbulent mixture of water/air which is applied to the back surface of the mat. As pressure pulses swell and subside in alternation, the protruding members are caused to manipulate the user's body producing a stimulating, therapeutic massage effect. Simultaneously, the water/air mixture is forced through the apertures of the mat producing a turbulent bath having a high proportion of air bubble content which further manipulates and massages the user's body. A pulsator mechanism, particularly adapted for use with the flexible mat, is comprised of a cylindrical housing in which a centrally mounted shaft driven by a paddle-wheel type impeller turns a rotor cylinder causing apertures in the rotor cylinder to align and misalign in alternation with a matching hole pattern on an adjacent fixed plate, thereby causing, in rapid alternation, interruption and reinstatement of water flow to produce tbhe pulsation of pressure which is required to agitate the flexible mat. An air inlet in the vicinity of the rotor cylinder and fixed plate allows air to be entrapped in the water, thereby producing the water/air mixture. Deliberately induced mechanical vibration of the pulsator is transmitted directly to the enclosure which supports the flexible mat thereby further enhancing the desired massage effect.
