Magnetic zaps to the brain aim to restore arm movement in stroke survivors
NCT ID NCT05535504
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a magnetic device (rTMS) placed on the scalp could help people who had a stroke regain movement in their arm. The trial planned to include 60 adults with recent ischemic stroke. However, the study was terminated early, so the results are not complete.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- repetitive transcranial magnetic stimulation (rTMS) device
- What this could lead to
- If it had worked, this could point toward a non-invasive way to improve arm function after a stroke.
- What could go wrong
- The trial was terminated early, so we don't have clear evidence it works. It was also a small study with only 60 participants.
