Hydrotherapy is a therapeutic approach in the aquatic environment. The water facilitates freedom of movement, promoting improved range of motion and functional strength. Performing exercise in therapeutic temperature waters (29-32 degrees) favors the thermal effect that changes the muscle tone and reduces pain, promoting well-being. Ease of movement grants relaxation and muscle stretching and reduces stiffness. The water brings buoyancy and lightness, which combined with the water movement resistance, helps to increase muscle strength and endurance.
