Often after an injury or surgery, a patient’s sensitivity to pain is increased while weight bearing is limited, which restricts his/her activities on land. In water the effects of gravity are reduced and functional activity and motion can occur. The properties of water allow for a patient to exercise in a relative “low or no impact” environment that provides more comfortable movement and enhanced range of motion. Water supports the body, reduces joint stress, and provides resistance to movement in a truly unique manner. Patients can improve mobility, strength, and function rapidly during the healing process, with the comfort of a warm, relaxing, therapeutic environment.
