Shockwave Therapy for Achilles Tendinopathy: Benefits, Evidence & Risks

What is Achilles tendinopathy?

The Achilles tendon connects the calf muscles to the heel bone. Tendinopathy can cause pain, stiffness and reduced tolerance of activities such as walking, running or jumping.

The distinction matters when planning exercises and discussing treatment. A programme suited to one presentation may need adapting for another.

Why start with rehabilitation?

Progressive strengthening is a central part of treatment. The starting load, movement range and progression should reflect your symptoms and physical capacity.

Activity adjustments can help make the programme manageable. Complete prolonged rest is usually not the long-term solution.

Recovery commonly takes several months. A course of treatment is not a promise that the tendon will be fully recovered in twelve weeks.

What is shockwave therapy?

Extracorporeal shockwave therapy, or ESWT, delivers mechanical pressure or acoustic waves through the skin using a handheld applicator. It does not involve an electrical shock or an incision.

Radial and focused treatments use different delivery methods. Ask which is proposed and why it is appropriate for your presentation.

How effective is it?

Results vary. NICE describes the evidence for effectiveness in Achilles tendinopathy as inconsistent and limited in quality and quantity. This is not a blanket endorsement of reliable pain relief.

Evidence also needs to match the type of tendon problem and treatment used. A randomised trial published in 2025 found that adding radial shockwave to exercise and education for insertional Achilles tendinopathy did not improve outcomes compared with sham treatment at six or twelve weeks.

When might it be considered?

Shockwave may be discussed when symptoms remain troublesome despite an appropriate rehabilitation programme. Review the diagnosis, exercise plan and goals first.

If offered, agree what benefit you hope to achieve, how progress will be measured and when to review the plan. Further sessions should follow a reasoned discussion rather than an automatic extension of treatment.

What happens during treatment?

Gel is applied and an applicator is placed over the treatment area. The delivery can be uncomfortable; tell the clinician so settings can be adjusted.

Courses often involve several appointments, but the number and spacing should be explained before you start. Rehabilitation remains important.

Does everyone need an ultrasound scan?

Imaging may help answer a particular clinical question, such as concern about a tear. Ask whether a scan is needed and what the assessment and treatment fees include.

What are the risks and suitability checks?

Possible effects include temporary pain, redness, bruising, swelling or altered sensation. There is also a small risk of tendon rupture or damage to surrounding tissues.

Tell your clinician about all medicines, recent injections, previous tendon tears, pregnancy, blood-clotting problems, infection and implanted devices. These can affect suitability.

Do not stop prescribed medicines yourself. Ask for individual advice about pain relief and aftercare.

What should you do afterwards?

Follow the agreed limits on running, jumping and other demanding activity. Even if pain temporarily improves, do not use that as a reason to test the tendon with a hard session.

Return gradually using your rehabilitation plan. Contact the clinic about significant or persistent worsening.
