Could soundwaves heal diabetic foot ulcers faster?
NCT ID NCT05380544
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This pilot study tests whether high-power soundwaves (shockwave therapy) can help heal diabetic foot ulcers faster. 77 participants will receive either high-dose, low-dose, or sham (fake) treatment over three sessions in one week. Researchers will track healing and quality of life for six months to see if this approach is worth studying further.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Extracorporeal shockwave therapy (ESWT) - high-power soundwaves delivered to the ulcer
- What this could lead to
- If it works, this could point toward a new, non-invasive way to help diabetic foot ulcers heal faster and reduce amputations.
- What could go wrong
- This is a small pilot study testing feasibility, not effectiveness. The ideal dose is unknown, and results may not confirm benefit.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * At least one unhealed diabetic foot ulcer below the level of the medial malleoli that has been present for more than 4 weeks * Absolute toe pressure greater than or equal to 50mmHg or an Ankle Pressure Brachial Index (ABPI) equal to or greater than 0.7(24, 25) * Capacity to consent to participate in the trial and given written informed consent * Willing to be randomised to either sham, low-dose or high-dose ESWT * Willing to consent to photography of the index DFU * Willing to comply with the follow up schedule Exclusion Criteria: * Interdigital index ulcer. This is because the ESWT delivery paddle does not fit between digits. * Currently on or planned treatment for osteomyelitis. * Currently taking any therapeutic anticoagulation medications. This includes novel oral anticoagulants, therapeutic doses of heparin and vitamin-K antagonists. This is a contraindication to ESWT. * Diagnosis of malignancy in the treatment area or haematological, disseminated or lymphatic malignancy. This is a contraindication to ESWT. * All who are pregnant, trying to conceive or breastfeeding. This is a contraindication to ESWT. * Active participants in other trials that may conflict with the study outcomes, for example any other wound care trials.
