What Is Ultrasound Therapy?

If you have been treated by a physical therapist or chiropractor for pain, you may have had an ultrasound treatment. It is a common modality used in the initial stages of treatment for sports injuries, soft-tissue injuries from accidents or pain from arthritis and other joint diseases. Ultrasound can be used for both joint and muscle pain. The effectiveness of ultrasound treatments can vary from patient to patient.

Identification

An ultrasound machine consists of a console where the intensity of the treatment can be adjusted by the therapist. Attached to the machine is a rounded probe that is rubbed on top of the skin to deliver the ultrasound treatment.

Function

An ultrasound machine produces high-frequency sound waves (too high for human ears to hear) that are transferred to your body through the probe. The sound waves travel deep into your tissues and muscles and create a sensation of tingling or gentle heat.

Process

First, a hypoallergenic gel is placed on the skin to create a friction-free surface. Your therapist may also combine anti-inflammatory medication with the gel. The sound waves force the medication into the tissues to reduce pain and inflammation.

Benefits

The sound waves created by the ultrasound treatment make your tissues vibrate, which creates heat. Heat can encourage the blood vessels to dilate, which brings blood, oxygen and nutrients to the area. Increased blood flow can also remove waste products produced by the cells.

Uses

Patients who have ultrasound treatments may experience relief from pain, decreased inflammation, fewer muscle spasms and, in some cases, improved range of motion.
