NCT ID NCT04442321
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a treatment for tennis elbow (lateral epicondylalgia) using ultrasound-guided percutaneous electrical stimulation (PENS) on the radial nerve, combined with exercise. Sixty adults with confirmed tennis elbow were split into two groups: one received real PENS plus exercise, the other a sham (fake) PENS plus exercise. The goal was to see if the real treatment reduced pain and disability better than the sham.

What this could lead to
If it works, this could offer a new, non-surgical way to ease pain and improve function in people with tennis elbow.
