Therapeutic ultrasound for acute ankle sprains in chiropractic

July 8, 2013 | 0 Comments

Hi, guys. This is Marco Abanico with Chiropractic Television.

Therapeutic ultrasound is a commonly used treatment for a variety of musculoskeletal conditions.  Ankle sprains are among the most commonly seen sport-related injuries and proper acute management can significantly improve the rate of healing and return to activity.  A major goal during the acute stage of healing is to control pain and inflammation.  The delivery of therapeutic ultrasound to an acutely sprained ankle can reduce pain and swelling while facilitating tissue healing.

What is therapeutic ultrasound?

Unlike diagnostic ultrasound that produces an image of something inside the body, therapeutic ultrasound consists of the application of high-frequency mechanical vibrations created by the conversion of electrical energy to sound waves.  Therapeutic ultrasound is typically applied at a frequency of either 1 or 3 MHz, depending on the depth of the target tissue.  Lower frequency, such as 1 MHz, targets deeper tissue, like a deep thigh muscle, while higher frequency, such as 3 MHz, is absorbed more superficially, like on the Achilles tendon.

What are the effects of therapeutic ultrasound?

Therapeutic effects of ultrasound are typically divided into thermal and nonthermal effects.  Nonthermal effects are those that are thought to be therapeutic in the acute stages of healing and include increased fluid movement in the area, increased protein synthesis, and improved blood flow.  These effects lead to reduced pain and swelling, and improved tissue healing.  The application is simple, consisting of placing a water-based gel on the skin, and then moving the sound head in small circles over the target area.

Therapeutic ultrasound for acute ankle sprains

A sprained ankle occurs when ligaments that stabilize the ankle are stretched or torn, resulting in acute pain, swelling, and loss of function.  Since the ligaments in the ankle are very superficial, your chiropractor may apply non-thermal, 3 MHz ultrasound over and around the damaged ligaments.  Treatment time varies but usually falls between five and 10 minutes per treatment, during which the patient feels nothing more than the movement of the applicator against the skin.

Is therapeutic ultrasound the right treatment?

While there is some controversy in the research regarding the benefits of therapeutic ultrasound for acute ankle sprains, the procedure is generally safe and effective on patients.  Make sure to tell your chiropractor of any conditions that may be contraindications for ultrasound, including metal implants, pregnancy, decreased sensory perception, cancer, or circulatory impairments.  In most cases, the application of non-thermal ultrasound to an acutely sprained ankle can reduce pain, shorten healing time, and get you back on track to normal activity.
