Shockwave therapy may ease stubborn achilles pain
NCT ID NCT07685509
First seen Jul 06, 2026 · Last updated Jul 07, 2026 · Updated 1 time
Summary
This study tests whether adding shockwave therapy to a tailored exercise program reduces pain and improves function in people with Achilles tendon pain. Two hundred adults with pain in the mid-portion or insertion of the tendon will be randomly assigned to exercise alone or exercise plus six shockwave sessions. The trial also examines changes in tendon blood flow and immune cells, aiming to understand why some cases persist.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- radial shockwave therapy
- What this could lead to
- If it works, this could provide a better treatment option for persistent Achilles tendon pain, potentially reducing the need for surgery.
- What could go wrong
- This is a mid-sized trial, and the added benefit of shockwave over exercise alone may be small or absent. Results may not apply to all types of tendon pain.
