Ultrasound therapy works by:


Increasing blood flow- The thermal energy from the ultrasound waves dilates blood vessels, which increases the delivery of oxygen and nutrients to cells.
Improving tissue healing- The sound waves cause cells in the tissue to vibrate, which speeds up healing.
Reducing inflammation- The heating effect of the ultrasound can help reduce chronic inflammation.
Improving lymph flow- The ultrasound helps tissue fluids flow better, which allows more white blood cells to pass through the tissues to help fight infections
