Higher voltage nerve zap may ease chronic migraine

NCT ID NCT07500558

First seen Jun 24, 2026 · Last updated Jun 24, 2026

Summary

This study tests whether using a higher voltage during a nerve-blocking procedure (pulsed radiofrequency) can better relieve pain in people with chronic migraine who haven't responded to at least two preventive medications. One hundred participants will be randomly assigned to receive either standard or higher-voltage treatment, guided by ultrasound. The main goal is to see if more people get at least 50% pain reduction with the higher voltage.

What this could mean

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

Active substance

pulsed radiofrequency (standard or higher voltage) applied to the sphenopalatine ganglion

What this could lead to

If it works, this could offer a better, longer-lasting pain relief option for people with chronic migraine who haven't responded to medications.

What could go wrong

This is a small, early-stage trial (100 people) comparing two similar procedures. The higher voltage may not provide extra benefit and could cause discomfort or rare nerve issues.
