NCT ID NCT07162311

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study tests whether a gentle electrical brain stimulation device, used at home, can reduce chronic pain in people with rheumatoid arthritis whose inflammation is already well-controlled. Thirty-four participants will either receive real or sham stimulation over several sessions. The goal is to see if this non-invasive approach can improve pain, function, and quality of life without extra drugs.

What this could mean

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

Active substance

transcranial direct current stimulation (tDCS) device

What this could lead to

If it works, this could offer a safe, non-drug option to manage chronic pain in rheumatoid arthritis patients, reducing reliance on painkillers.

What could go wrong

This is a small early-stage trial with only 34 people, so results may not apply widely. The effect may be small or no better than a placebo, and home use could lead to inconsistent dosing.
