Therapeutic ultrasound is a modality that has been used by Physiotherapists since the 1940’s. Ultrasound is applied using the head of an ultrasound probe that is placed in direct contact with your skin via a transmission coupling gel. Therapeutic ultrasound has been shown to cause in increase in:
-local blood flow
-scar tissue breakdown
How can Ultrasound help you?
The effect of ultrasound via an increase in local blood flow can be used to help reduce local swelling and chronic inflammation, and according to some studies, promotes bone fracture healing. The intensity or power density of the ultrasound can be adjusted depending on the desired effect. A greater power density (measured in Watt/cm2) is often used in cases when scar tissues breakdown is the goal.
Ultrasound can also be use to achieve phonophoresis. This is a non-invasive way of administering medications to tissues below the skin, perfect for patients who are uncomfortable with injections. With this technique,the ultrasonic energy forces the medication used substances delivered in this way.
The most common conditions treated with ultrasound includes soft tissue injuries such as tendonitis (or tendinitis), non-acute join swelling and muscle spasm. Most muscle and ligament injuries can benefit from therapeutic ultrasound.
