You asked: Where should you not use ultrasound therapy?

Near the eyes: Damage to the retina or lens may result if ultrasound is used near the eyes. Areas around the heart: It is suggested that ultrasound may alter the electrical signals around your heart. If you have a pacemaker, ultrasound may interfere with its normal function.

What area ultrasound should not be used to treat?

Therapeutic ultrasound is not used for problems near a pregnant woman’s womb because it could put the pregnancy at risk. It’s also generally not used over the spine, eyes, pacemakers, other implants, and areas with active infections.

Can ultrasound therapy be harmful?

It has the potential to produce harm if the heat is left in the same place too long. If, while being treated, you feel discomfort, alert your PT right away. One potential risk with therapeutic ultrasound is that the rapid pressure changes during cavitation could cause a “microplosion” and damage cellular activity.

Can ultrasound therapy be used on the neck?

Conclusions: Therapeutic ultrasound is frequently used in the treatment of LBP and neck pain and is often combined with other physiotherapeutic modalities.

What are some contraindications for ultrasound?


  • ESWL – Infection, stone burden greater than 2.5 cm; coagulopathies, untreated hypertension, pregnancy-ESWL.
  • MRgUS – Cardiac pacemaker or other implantable devices.
  • Ultrasound diathermy – Bone fracture, malignancy, arteriosclerosis, application to eye, spine, active infection, or ischemic tissues.

Why is ultrasound used in physical therapy?

The sound waves, or ultrasound rays, penetrate within the body generating heat increasing blood flow, and relaxing muscles and connective tissues thereby reducing pain and muscle spasms. The stimulation of these tissues in this way encourages repair and can greatly reduce the healing time of certain injuries.

Can I use ultrasound on my knee?

Ultrasound, commonly used to image the inside of the body through soundwaves, can also be used at higher intensities to relieve pain,2 promote healing, and reduce swelling. Clinicians currently use ultrasound therapy for knee pain, treating it for several minutes a few times a week in the office.

What are the side effects of ultrasound?

Unlike some other scans, such as CT scans, ultrasound scans don’t involve exposure to radiation. External and internal ultrasound scans don’t have any side effects and are generally painless, although you may experience some discomfort as the probe is pressed over your skin or inserted into your body.

Can ultrasound aggravate an injury?

Ultrasound and the stage of injury

A reduction in pain and tenderness and increased muscle strength in DOMS has been reported [50], but this has not been confirmed by other workers [51]. There is evidence that thermal doses of ultrasound in DOMS can aggravate pain and stiffness [52].

Does ultrasound have radiation?

Ultrasound imaging is extremely safe and does not use radiation. Ultrasound scanning gives a clear picture of soft tissues that do not show up well on x-ray images. Ultrasound is the preferred imaging modality for the diagnosis and monitoring of pregnant women and their unborn babies.

Can ultrasound relax muscles?

“The deep heat generated by ultrasound can relax tense or strained muscles, minimizing muscle spasms and shortened muscles often associated with tension or injury.” Ultrasound therapy, along with range of motion exercises, can increase range of motion and help conditions such as osteoarthritis and phantom limb pain.

Does ultrasound help with inflammation?

Ultrasound (US) therapy is used to reduce pain and inflammation and to accelerate healing after soft tissue injury.

Does ultrasound show muscle damage?

An ultrasound of the same muscle injury will show individual fibers of the muscle and injury changes. Both MRI and ultrasound will detect large muscle injuries and tears. Ultrasound is best used for discovering and diagnosing muscle micro-tears and chronic conditions.

When should you not use ultrasound?

Cancer: Since ultrasound may increase cellular activity, it should not be used over cancerous areas of the body as this is thought to increase chances of metastasis.

How does ultrasound work in physiotherapy?

Ultrasound therapy causes mechanical vibrations, from high frequency sound waves, on skin and soft tissue via an aqueous solution (Gel). A gel is applied either to the applicator head or to the skin, which helps the sound waves to evenly penetrate the skin.

Can ultrasound therapy break up scar tissue?

One of the many benefits of ultrasound therapy is breaking up scar tissue caused by injuries or surgery. Scar tissue can cause pain and restrict joint movement. Ultrasound helps by using high-frequency sound waves to break the fibres of the scar tissue down into smaller fragments.
