What is a hydropool?

A hydropool (short for hydrotherapy pool) uses physical water properties such a temperature and pressure to allow essential physiotherapy to be carried out in a relaxed and safe environment. The water is usually kept at 33-36°C to keep users warm and comfortable while also providing the optimum temperature for the stretching of muscles.
 
Hydropools also include light and sound systems to provide a rich sensory (and often interactive), experience. Ambient room lighting, underwater lighting and shape/pattern projection is used to provide visual stimulation, while underwater speakers and a surround sound system provide auditory stimulation. Floating switches and voice commands can be used to interact with the pool and room, allowing for reward-based activities or simply encouraging independence.
