Ultrasound therapy uses high-frequency sound waves to produce heat that can reduce pain. It may be used to treat conditions such as musculoskeletal injuries, arthritis and fibromyalgia.

Typically performed during physical therapy, occupational therapy or manipulation therapy, ultrasound therapy provides deep heat to the affected tissues. It may help:

• Stimulate healing without causing irritation
• Speed metabolism and improve circulation
• Break up and soften scar tissue and adhesions
• Reduce chronic inflammation or swelling
• Reduce irritation to nerve roots
• Enhance the body’s natural healing process

Ultrasound therapy is generally safe. However, it does carry some risks, such as the potential for burns. Patients are advised to consult with their physician before receiving therapeutic ultrasound. It is not recommended in some cases, such as over a pacemaker, near the abdomen of a pregnant woman, or over the skull, eyes, heart or reproductive organs. It is generally avoided in areas affected by cancer.

Therapeutic ultrasound differs from diagnostic ultrasound, which uses less-intense sound waves to create images of internal structures.
