Can magnetic pulses boost shock wave therapy for tennis elbow?
NCT ID NCT07802938
First seen Sep 03, 2026 · Last updated Sep 04, 2026 · Updated 1 time
Summary
This trial tests whether adding pulsed electromagnetic field therapy (PEMF) to standard shock wave therapy eases pain and improves function in adults with tennis elbow, a condition causing pain on the outer side of the elbow. About 70 people with symptoms lasting at least 3 months will receive either shock wave therapy plus active PEMF or shock wave therapy plus a sham PEMF device, once a week for 5 weeks. Researchers will measure pain, grip strength, and tendon appearance on ultrasound before treatment, right after the 5 weeks, and again 3 months later.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Pulsed electromagnetic field therapy (PEMF) added to extracorporeal shock wave therapy (ESWT)
- What this could lead to
- If it works, adding PEMF to shock wave therapy could offer a drug-free way to reduce pain and improve grip strength in people with tennis elbow.
- What could go wrong
- This is a small, early-stage trial, and the sham control means some improvement may come from placebo. The added benefit of PEMF may turn out to be small or absent.
