Ultrasound has been around since the 1940s and has various uses from diagnostic to therapeutic. Therapeutic ultrasound is used by chiropractors, physical therapist, medical doctors and even hospitals. Therapeutic use involves using an electronic device with an attached wand that is glided over the skin of the injured region. This wand sends high frequency sound waves into the underlying tissue to provoke or stimulate the tissue for various purposes. The main therapeutic value of ultrasound is for it’s ability to apply deep heat to the underlying tissue for tissue relaxation, increasing blood flow, and the breaking up of scar tissue. Often, patients will not feel anything during the treatment other than a subtle warming sensation as the wand glides over the skin. The results of treatment are often determined by observing the patient’s overall symptoms between the treatment and their next visit.
