What is therapeutic ultrasound?
Therapeutic ultrasound as a treatment modality that has been used by therapists over the last 50 years to treat soft tissue injuries. Ultrasonic waves (sound waves of a high frequency) are produced by means of mechanical vibration of the metal treatment head of the ultrasound machine. This treatment head is then moved over the surface of the skin in the region of the injury. When sound waves come into contact with air it causes a dissipation of the waves, and so a special ultrasound gel is placed on the skin to ensure maximal contact between the treatment head and the surface of the skin.
