What is Therapeutic Ultrasound?

It is a form of MECHANICAL energy or a deep heating modality. Mechanical vibration at increasing frequencies is known as sound energy. The normal human sound range is from 16Hz to something approaching 15-20,000 Hz (in children and young adults). Beyond this upper limit, the mechanical vibration is known as ULTRASOUND. The frequencies used in therapy are typically between 1.0 and 3.0 MHz (1MHz = 1 million cycles per second). *1.0 MHz penetrates deeper into the tissue than 3.0 MHz.

Ultrasound is applied using a round-headed wand that is put in direct contact with the patient’s skin. Ultrasound gel must be used on all surfaces of the head in order to allow the transmission of the ultrasonic waves which cannot travel through air.
