Ultrasound machines are a treatment modality used by health care professionals that utilize high or low frequency sound waves. These sound waves are transmitted to the surrounding tissue and vasculature. They penetrate the muscles to cause deep tissue/muscle warming. This promotes tissue relaxation and therefore is useful in treating muscle tightness and spasms. The warming effect of the sound waves also cause vessel vasodilatation and increase circulation to the area that assists in healing. The frequency on the machine can be adjusted to use waves that will decrease inflammation.
Therapeutic Ultrasound has been used in rehabilitation for many years and has a proved track record. It is widely used in sports related injuries or any trauma affecting the soft tissues.
