The OCEAN underwater and whirling massage bath tub can treat the entire body or its parts with the application of a water stream underwater through the use of a jet or massage jet mounted on a hose. The massage has both thermal and mechanical effects. Muscles relax through the use of adequate bath and water stream temperature. The water stream pressure causes muscles to heat up, achieving both metabolic and neural effects. You can treat joint and muscle injuries, post-traumatic states, poor blood circulation in the extremities, obesity, ischialgia, and spastic and atonic polio.
