Sound waves could ease chronic leg swelling
NCT ID NCT07626645
First seen Jun 27, 2026 · Last updated Sep 16, 2026 · Updated 2 times
Summary
This study tests whether a device that delivers sound waves (shock wave therapy) can help reduce leg swelling and improve quality of life in people with lower limb lymphedema. Thirty-six adults who are already using standard care will either get real or fake (sham) treatments twice a week for five sessions. Researchers will measure changes in leg volume, skin thickness, pain, and function.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Extracorporeal shock wave therapy (ESWT) using a device that delivers sound waves to the leg
- What this could lead to
- If it works, this could offer a new, non-invasive way to reduce leg swelling and improve comfort for people with lymphedema who still have symptoms despite standard care.
- What could go wrong
- This is a small, early-stage trial with only 36 people, so results may not apply to everyone. The treatment is added to standard care, so any benefit may be modest.
