When hearing the term ultrasound, most people will immediately jump to its utilization as an imaging technique in diagnostics or pregnancy. In fact, according to one study out of England, ultrasound was the second-most prevalent imaging test ordered with 9.51 million ultrasounds performed in a single year. While its use in diagnostics is exceptional, the technique also serves as a commonly used therapeutic modality in recovery and rehabilitative settings. Interestingly, the use of ultrasound therapy as a treatment has been around for decades dating back to the1930s, and has helped millions of individuals in their recovery process. While technology has evolved and evidence-based research on the modality has expanded, knowledge relating to both indications and contradictions has grown exponentially. Follow along as we break down the safe use of Ultrasound Therapy and review some of our favorite devices on the market today.
Ultrasound therapy is generally considered both safe and therapeutic when used properly and for the appropriate indications. Suitable application involves choosing the correct intensity, frequency, and duration that aligns with your specific treatment goals and using the device according to the manufacturer’s recommendations. It is important that overexposure to any one location is avoided, as this can increase the risk of burns on the skin surface and can even cause internal bleeding and scarring in extreme cases. Note these complications are rare and can be avoided entirely with proper use.

When using thermal settings, ultrasound therapy will create a mild heat mimicking a warm massage-like sensation for users. In certain cases, you may feel some light tingling or vibrations as the ultrasound waves pass through the tissues, but this is generally a quite pleasant experience.

With proper application, side effects should not occur with ultrasound. That said, if the intensity is too high, minor pain or discomfort may occur - this can be mitigated with a reduction in intensity. As mentioned earlier, burns or other injuries can occur if the device is kept over a specific area for a prolonged period or if the settings are inappropriately set.
While this modality is considered safe for most patient populations, there are certain individuals who should avoid ultrasound therapy. Contraindications for use include individuals during pregnancy, those with implants or pacemakers, near or over open wounds, and around the eyes or genitals. In addition, ultrasound should be avoided over active infections and malignancies as well as over unstable fractures.

Besides ultrasound therapy, shockwave therapy also sends specific wavelengths into the tissues to promote therapeutic change. While there may be some crossover, the therapies differ in both their mode of delivery as well as the specific conditions they treat.
Shockwave therapy is better suited for conditions that may benefit from tissue stimulation whereas ultrasound helps with the deep heating of tissues. Each is appropriate for specific populations and acuities therefore we recommend consulting with your medical team to determine which may be most appropriate for you.
Ultrasound therapy is a safe and effective therapeutic modality that can be used to reduce pain, improve circulation, enhance deep heating, and promote tissue healing. Appropriate use is essential and ensuring your device is both properly maintained and of high quality is key to reaping the desired benefits.
