Ultrasound Therapy Physiotherapy

Therapeutic ultrasound is a modality that has been used by physiotherapists since the 1940s. 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 increases in:

• healing rates
• tissue relaxation
• tissue heating
• 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, promote 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 where scar tissue breakdown is the goal.

Ultrasound can also be used 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 through the skin. Cortisone, used to reduce inflammation, is one of the more commonly used substances delivered in this way.

The most common conditions treated with ultrasound include soft tissue injuries such as tendonitis (or tendinitis if you prefer), non-acute joint swelling and muscle spasm. Most muscle and ligament injuries can benefit from therapeutic ultrasound.

What is an Ultrasound Dose?

A typical ultrasound treatment will take from 3-5 minutes. In cases where scar tissue breakdown is the goal, this treatment time can be much longer. During the treatment the head of the ultrasound probe is kept in constant motion. If kept in constant motion, the patient should feel no discomfort at all.

Some conditions treated with ultrasound include tendonitis (or tendinitis if you prefer), non-acute joint swelling and muscle spasm.
