It is a field of research dedicated to understanding and augmenting rehabilitation through the application of Robotic Devices. Rehabilitation robotics includes development of robotic devices tailored for assisting different sensorimotor functions (e.g. arm, hand, leg, ankle, development of different schemes of assisting therapeutic training, and assessment of sensorimotor performance (ability to move) of patient; here, robots are used mainly as therapy aids instead of assistive devices. Rehabilitation using robotics is generally well tolerated by patients and has been found to be an effective adjunct to therapy in individuals suffering from motor impairments, especially due to stroke.

Formally called Hydropathy and also called water cure, Hydrotherapy is a part of alternative medicine (particularly naturopathy), occupational therapy and physiotherapy, that involves the use of water for pain relief and treatment. The term encompasses a broad range of approaches and therapeutic methods that take advantage of the physical properties of water such as temperature and pressure, for therapeutic purposes, to stimulate blood circulation and treat the symptoms of certain diseases.
