Ultrasound is an electrotherapy. The ultrasound head in the hand-piece puts out vibrational waves. When placed on the body with some gel for contact these vibrational waves enter the body oscilating the cells. This micro-massage can be set to different depths and for varying times. Treatment can be varied dependent on area, depth of structure, acute/chronic injury. It is most suited to ligament and tendon damage.
Ultrasound equipment is sanitised between patients.
