Ultrasound is a machine that produces high frequency sound waves that are transmitted into the body via a sound head or probe. The sound waves travel deep into the body generating a gentle soothing heat.
The probe of the ultrasound machine generates a high frequency sound wave. The physical therapist applies a gel to the skin, which helps the sound waves to be transmitted into the body more efficiently. Using a gentle circular motion with the probe the therapist then moves the sound head over the area to be treated. The treatment lasts between 5 to 10 minutes depending upon the size of the area to be treated. We also use the ultrasound to push an anti-inflammatory medication through the skin.
As the sound head moves over the surface of the skin, the sound waves penetrate the body, creating heat. The heat in turn creates vasodilation. Vasodilation is an enlarging of the blood vessels, serve to bring nutrient and oxygen rich blood to the injured area to speed up the healing process.
