Hydrotherapy
The therapeutic use of water — including pools, whirlpools, and aquatic exercise — to facilitate rehabilitation of musculoskeletal, neurological, and pain conditions.
Full Definition
Hydrotherapy encompasses a range of water-based interventions used in physical medicine and rehabilitation, exploiting buoyancy, hydrostatic pressure, and thermal properties to reduce pain, improve range of motion, and support early weight-bearing. It is frequently prescribed post-orthopedic surgery or for patients with neurological deficits for whom land-based exercise is contraindicated or too demanding. Aquatic therapy pools used in PM&R settings are typically maintained at therapeutic temperatures (between 33–36 °C). Editors should note that 'hydrotherapy' and 'aquatic therapy' are often used interchangeably in clinical documentation, though some style guides distinguish them. The term is always lowercase unless beginning a sentence.
Usage
Usage note: Do not capitalise mid-sentence. Distinguish from 'balneotherapy,' which typically refers to mineral-water immersion for dermatological or rheumatological purposes rather than active exercise-based rehabilitation.
