Hydrotherapy
The therapeutic use of water—exploiting its buoyancy, resistance, and thermodynamic properties—to facilitate movement, pain relief, and cardiovascular exercise in rehabilitation.
Full Definition
Hydrotherapy (also termed aquatic therapy or aquatic physiotherapy) uses the physical properties of water—buoyancy reducing effective body weight, hydrostatic pressure aiding venous return, and viscosity providing resistance—to enable exercise that may not be feasible on land. It is applied in musculoskeletal rehabilitation, neurological rehabilitation, and pediatric settings. Editors should note that 'hydrotherapy' is one word with no hyphen and that 'aquatic therapy' is the preferred term in some professional associations. The two terms may be used interchangeably unless a jurisdiction-specific or institutional style preference applies.
Usage
Usage note: One word, no hyphen. 'Aquatic physiotherapy' is preferred in some UK and Australian contexts; confirm house style. Do not use 'water therapy' in formal clinical documents.
