Zapping a nerve in the ear might ease lingering lyme disease symptoms

NCT ID NCT04938687

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This pilot study tested a device called RAVANS that delivers mild electrical pulses to a nerve in the ear, aiming to reduce symptoms of post-treatment Lyme disease syndrome (PTLDS). Fifteen adults with PTLDS received either real or sham stimulation. The main goal was to see if the treatment could lower symptom scores on a detailed questionnaire. Because this is a very small early study, the results are preliminary and need confirmation in larger trials.

What this could mean

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

Active substance

respiratory-gated auricular vagal afferent nerve stimulation (RAVANS) device

What this could lead to

If it works, this could point toward a drug-free way to manage lingering Lyme symptoms like fatigue and pain.

What could go wrong

This is a very small pilot study with only 15 people, so results may not apply widely. The device is experimental and may not provide meaningful relief.
