Ultrasonic waves (sound waves of a high frequency) are produced by means of mechanical vibration of the metal treatment head of the ultrasound machine. The treatment head is moved over the surface of the skin in the area of the injury. When sound waves come into contact with air, waves dissipate, so a special ultrasound gel is used on the skin to ensure maximal contact between the treatment head and the surface of the skin.
As the ultrasound waves pass into the skin, they cause a vibration of the surrounding tissues. This increased vibration leads to the production of heat within the tissue. In most cases this cannot be felt by the patient themselves. This increase in temperature may cause an increase in the flexibility of ligaments, tendons, scar tissue and fibrous joint capsules. In addition, heating may also help to ease muscle spasm and pain and promote the healing process.
We use it for swollen discs, torn muscles, sore muscles, nerve irritation and joint problems. It is also used as a preparatory therapy for adjustment or Graston therapy.
