Zapping the brain or spine to ease stubborn pain: which works best?
NCT ID NCT02817880
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested three types of non-invasive brain or spinal stimulation (tDCS, rTMS, and tsDCS) to see which best reduces pain in people with algoneurodystrophy, a chronic pain condition. 36 adults who had pain for over a year and didn't respond to drugs took part. The goal was to compare how well each method eases pain and improves quality of life.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
brain and spinal stimulation devices (tDCS, rTMS, tsDCS)
What this could lead to
If successful, this could point toward a non-drug option for managing long-term pain in algoneurodystrophy.
What could go wrong
This is a small, completed study with only 36 participants, so results may not apply widely. The effects may be modest or temporary.
