What does therapeutic ultrasound do in physical therapy f gas regulations


Stable cavitation is desired when your physical therapist is applying ultrasound to your body. Unstable cavitation can be dangerous to your body’s tissues, and your physical therapist will ensure that this does not occur during the application of ultrasound. How Does Ultrasound Work?

Inside your PT’s ultrasound unit is a small crystal. When an electrical charge is applied to this crystal, it vibrates rapidly, creating piezoelectric waves. These waves are emitted from the ultrasound sound head as ultrasound waves. The ultrasound wave then enters into your injured tissues during application of the modality. This increases blood flow and caviation, leading to the theorized benefits of the treatment. How Is Ultrasound Applied?

Ultrasound is performed with a machine that has an ultrasound transducer (sound head). A small amount of gel is applied to the particular body part; then your physical therapist slowly moves the sound head in a small circular direction on your body. The therapist may change various settings on the ultrasound unit to control the depth of penetration of the ultrasound waves or change the intensity of the ultrasound. Different settings are used in various stages of healing.

Your physical therapist may use ultrasound gel combined with a topical medication to help treat inflammation around soft tissue in the body. This process is called phonophoresis. While there is some evidence that ultrasound waves help deliver the medicated gel to the injured tissues, most published studies indicate that this treatment may be ineffective. Contraindications to Using Ultrasound

While you are receiving an ultrasound treatment, you will most likely not feel anything happening, except perhaps a slight warming sensation or tingling around the area being treated. If the ultrasound sound head is left in place on your skin and not moved in a circular direction, you may experience pain. If this occurs, tell your physical therapist right away. Common Injuries Treated with Ultrasound

Generally speaking, any soft-tissue injury in the body may be a candidate for ultrasound therapy. Your PT may use ultrasound for low back pain, neck pain, rotator cuff tears, knee meniscus tears, or ankle sprains. Ultrasound for Chronic Pain

There is some evidence that if you have chronic pain, you may benefit from ultrasound treatments. It is thought that the ultrasound waves help improve tissue extensibility and circulation, leading to increased mobility and, ultimately, decreased pain. Ultrasound may not work for everyone, but it is worth a try if you have chronic, unremitting pain. Some people may argue that the benefit of ultrasound for chronic pain is due to the placebo effect. But, if if gives you relief then it is the right treatment for you. Caution During Ultrasound

If you are going to physical therapy and are getting an ultrasound, you should know that many studies have found that ultrasound offers little benefit to the overall outcome of physical therapy. For example, if you have low back pain, ultrasound treatments have been shown to offer very little benefit. In fact, ultrasound received a grade of "C" (no benefit demonstrated) for knee pain, low back pain and neck pain in a series of papers published in Physical Therapy Journal in 2001. The evidence leads many to wonder if ultrasound really helps you in physical therapy.

A 2014 study in the American Journal of Physical Medicine and Rehabilitation examined the effect of ultrasound on pain and function in patients with knee osteoarthritis. The researchers found no difference in knee function and pain with rehab using ultrasound, no ultrasound, and sham (fake) ultrasound. So if you PT is providing ultrasound for you, one must question if it is really necessary as part of your overall rehab program.

Many people argue that ultrasound can have a negative effect on your physical therapy by needlessly prolonging your care. Ultrasound is a passive treatment. In other words, you can’t provide the treatment yourself; you are simply a passive receiver of the ultrasound. If your PT uses ultrasound during your to treatment, make sure you are engaged in an active exercise progrma to help improve your functional mobility. Exercise and active involvement should always be the main components of your rehab program. A Word from Verywell

Your physical therapist may use ultrasound to help improve your condition. If so, be sure to ask about the need for ultrasound. Also, be sure that you are also performing an active self-care exercise program in the PT clinic and at home. If you are actively engaged in your rehabilitation, you can ensure that you have a safe and rapid recovery back to normal function.
