Ultrasound is a therapeutic modality in which a wand is used to direct high-frequency sound waves into an injured tissue. These sound waves vibrate through the tissues being treated, resulting in a localized heating response.
This increase in temperature functions to improve blood circulation, break down scar tissue, and drive inflammation away from the site of injury. These effects facilitate healing by promoting the development of new connective tissue, at the site of injury, while simultaneously reducing pain levels.
The ability of ultrasound to reduce scar tissue can be further accelerated through the use of instrument assisted soft tissue mobilization (IASTM) and therapeutic exercises/stretches.
