NCT ID NCT07432841

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests a non-invasive brain stimulation technique called HD-tDCS for people with chronic pain that hasn't improved with other treatments. 144 participants will be randomly assigned to receive either real (anodal or cathodal) or sham (placebo) stimulation over five sessions in one week. The goal is to see if personalized targeting of a brain region involved in pain processing can reduce pain and improve daily functioning, with follow-ups at 3 weeks and 3 months.

What this could mean

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

Active substance

High-Definition transcranial Direct Current Stimulation (HD-tDCS)

What this could lead to

If it works, this could offer a non-drug option to reduce chronic pain by targeting specific brain areas with personalized stimulation.

What could go wrong

This is an early-phase study with only 144 participants. The effect may be small or temporary, and not everyone may benefit. Risks include mild discomfort or skin irritation from the electrodes.
