Water can be excellent environment for patients who have difficulty with weight bearing activities due to arthritis, recent fracture, sprain/strains, or excessive weight.
By exercising in water, vasodilation of blood vessels occurs. This will increase blood flow to the injury site, which results in increased oxygen and nutrient delivery as well as waste product removal. All of which will promote the healing process.
Another benefit of aquatic therapy is the added resistance that the patient experiences while in the pool for therapy. Air resistance is much less than water resistance, so patients in water use many more muscles and have stronger muscle contractions than they would by exercising on land. Other beneficial attributes associated with water physical therapy include, increased range of motion, improved balance and coordination, normalization of muscle tone, protection of joints during exercise, and reduction of stress.
