Hydrotherapy is different from swimming as it involves special exercises. The water temperature is usually 33–36ºC, which is warmer than a typical swimming pool. At CPCAP we use The Halliwick Swimming Method, which is based on scientific principles of hydrostatics, hydrodynamics and body mechanics for hydrotherapy. It was developed by James McMillan in 1949. The principles behind the swimming method can be applied to all people regardless of age or mental or physical ability.
