Needle vs light: which zaps shoulder pain best?

NCT ID NCT07695792

First seen Jul 10, 2026 · Last updated Jul 17, 2026 · Updated 1 time

Summary

This study tests whether two types of percutaneous electrolysis (simple or multifilar) or laser therapy better relieve pain and improve shoulder movement in people with supraspinatus tendinopathy, a common cause of shoulder pain. Participants receive one treatment session and are evaluated before, right after, 24 hours, and one week later. The goal is to find which technique offers faster and longer-lasting relief.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
percutaneous electrolysis (simple or multifilar) and laser therapy
What this could lead to
If one method proves superior, it could offer a more effective, non-surgical option for treating chronic shoulder tendon pain.
What could go wrong
This is a small, early-stage trial with only 60 participants, so results may not apply broadly. The invasive electrolysis procedure carries minor risks like pain or infection.
