Abstract: A submersive therapy apparatus which includes a tub filled with an aqueous solution adapted to provide physiotherapy and drug treatment to the body or body parts of a patient, such as the hands, arms, feet or knees, such aqueous environment containing a medicated fluid and/or other liquid medium. An array of stationary ultrasonic acoustic transducers are arrayed within the walls of the tub which are connected to movable ultrasound heads. The ultrasound heads are exposed on the surface of the inner tub walls to concentrate ultrasound energy on a body part target area. Additionally and alternatively to the delivery of ultrasound energy, rows of electrodes and coils are arranged around all sides of the inner walls or panels of the tub in alternating positive or negative polarities to deliver an electric current and/or provide an electromagnetic field.
