Ultrasound machines are a treatment modality 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 also be adjusted to use waves that will decrease inflammation.
Ultrasound is the best form of heat treatment for soft tissue injuries. It is used to treat joint and muscle sprains, bursitis, and tendonitis.
Ultrasound treatment is used to:
relieve pain and inflammation
reduce muscle spasms and
increase range of motion
Ultrasound makes high frequency sound waves. The sound waves vibrate tissues deep inside the injured area. This creates heat that draws more blood into the tissues. The tissues then respond to healing nutrients brought in by the blood and the repair process begins.
Treatment is given with a soundhead that is moved gently in strokes or circles over the injured area. It lasts just a few minutes. The procedure may be performed with the soundhead alone or combined with a topical anti-inflammatory drug or gel.
