Therapeutic Ultrasound uses high frequency sound waves that penetrate deep into tissues. Therapeutic ultrasound can be either thermal for a heating effect, or non-thermal (mechanical effect)for acute inflammation. Usually very little or no sensation of heat is felt by the patient.
Therapeutic ultrasound is very effective for treating:
Muscle contractures/scar tissue formation
Tendon and ligament injuries
Therapeutic ultrasound works by:
Breaking down scar tissue
Improving circulation (increases tissue vascularity which helps speed healing)
Decreasing pain due to the reduction of the inflammatory injury response and tissue swelling
Increasing tissue extensibility
Creating a deep heat within muscles to reduce muscle spasm and pain. This is also effective for preparing tissues for manual therapy techniques.
