Can you use ultrasound on Achilles tendonitis?

Can you use ultrasound on Achilles tendonitis?

Some of the pathological processes which occur in Achilles tendinopathy can be identified by ultrasound, which may also be used to direct local treatment. Pain in the hindfoot and heel is common.

Can ultrasound detect Achilles?

However, the diagnosis of an Achilles tendon rupture is not always clear clinically. Physical examination maneuvers to assess for a tendon injury can be limited by pain and soft tissue swelling. Ultrasound has been shown to be very sensitive in detecting an Achilles tendon rupture.

What is normal thickness of Achilles tendon?

Normal anatomic structures seen consistently included the Achilles tendon, the musculotendinous junction, the retrocalcaneal bursa, and the calcaneal tendon insertion site. The normal range of tendon thickness was 4-9 mm (mean, 6.2 mm).

What is the difference between thermal and nonthermal ultrasound?

Nonthermal effects are those usually associated with cavitation and its associated effects. Thermal effects are those due to heating and are accepted as including increased metabolic activity and blood flow and an analgesic effect on nerves. An additional claim is increased collagen extensibility.

What does an ultrasound show Achilles?

An Achilles tendon ultrasound will allow your doctor to visualise the underlying anatomic structures as well as their quality, with the ability to quickly formulate as diagnosis and determine the severity of the injury.

How do you measure Achilles tendon thickness?

The thickness of the Achilles tendons was measured in the transverse plane at the level of the medial malleolus. True tendon thickness was evaluated and it was defined as thickness perpendicular to the greatest width of the tendon. For each participant, the Achilles tendons were measured by two operators.

What does a thickened Achilles tendon indicate?

Achilles tendinosis: Gradual thickening of the Achilles tendon, due to aging or overuse. Despite the thickening, the tendon is weakened and prone to further injury or rupture. Achilles tendinopathy: A general term for tendinitis or tendinosis affecting the Achilles tendon.

What is non thermal ultrasound?

Nonthermal levels of ultrasound are reported to modulate membrane properties, alter cellular proliferation, and produce increases in proteins associated with inflammation and injury repair.

What is the difference between 1mhz and 3mhz ultrasound?

Therefore, 1-MHz continuous ultrasound, with a half-value depth of approximately 2.3 cm, is frequently used to treat deep tissues that are approximately 2.3 to 5 cm deep. With its smaller half-value depth, 3-MHz ultrasound is frequently used to heat tissues that are more superficial, from 0.8 to 1.6 cm deep.

What are the indications and contraindications of 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.

Does tendonitis show up on ultrasound?

The ultrasound can easily detect the swelling and inflammation of tendinitis or the chronic degenerative changes of tendinosis.

How is tendon stiffness measured?

The ratio of the force response to the displacement of the muscle-tendon complex gave a measure of the stiffness of the total complex. An adaptation of the method of Morgan (1977) allowed the stiffness to be separated into two components the stiffness of the muscle fibres and the stiffness of the tendon.

When is non thermal ultrasound used?

Is 1 MHz stronger than 3mhz?

3 MHz should be used when the tissues targeted are within 2.5 cm. [8] 3 MHz is a much more efficient frequency in regards to heating because it heats roughly 3x faster than 1 MHz. [3] 1 MHz should be used when wanting to affect deeper tissues. That would be considered up to 5 cm deep.
