Hydrotherapy in physical therapy involves the use of water as a therapeutic medium to promote healing and improve physical function. Patients engage in exercises and activities in a controlled aquatic environment, typically a pool, under the guidance of a rehabilitation assistant. The buoyancy of water reduces the impact on joints, facilitating increased range of motion and muscle strength. The warmth of the water also promotes relaxation and alleviates pain. Hydrotherapy is particularly beneficial for conditions like arthritis, musculoskeletal injuries, and neurological disorders. It offers a unique and effective approach to rehabilitation, harnessing water's properties to enhance mobility and recovery.
