Shockwave therapy may boost recovery from achilles pain, small study suggests
NCT ID NCT05702918
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether adding low-energy shockwave therapy to a 12-week exercise program helps people with Achilles tendinopathy more than exercise alone. Forty-seven adults with pain and swelling in one Achilles tendon were randomly assigned to either exercise plus shockwave or exercise only. Researchers used ultrasound images and a pain-and-function questionnaire to track changes over 26 weeks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- focused extracorporeal shock wave therapy and a 12-week resistance training exercise protocol
- What this could lead to
- If successful, this could point toward a standard non-surgical treatment plan that improves pain and function in people with Achilles tendinopathy.
- What could go wrong
- This is a small, completed study with only 47 participants. Results may not apply to everyone, and the treatments may not work better than exercise alone.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * the patient shows symptoms of Achilles tendinopathy (pain, swelling and dysfunction in the area of Achilles tendon), which at least partially limit his quality of life during normal or sporting activities, * the patient is in the age group of 18-60 years, * the patient has difficulties in only one lower limb; the second, asymptomatic limb will be considered the reference, * the patient is not aware of any mechanical damage to the tendon in symptomatic limb in the past (e.g. partial or complete rupture as a result of an injury), * the patient has not undergone any treatment aimed at AS in the last 3 months (surgery, corticoid application, plasma therapy, shock waves, physiotherapy, etc.), objective US examination of AS shows structural changes (expansion, neovascularization, focal hypoechoic areas, etc.). Exclusion Criteria: * patient has been diagnosed with a rheumatic disease or a disease of the central nervous system * patient has any condition which is contraindication for ESWT application * patient is aware of mechanical damage to the Achilles tendon as a result of an injury in the past.
