Brain zaps may restore movement in chronic stroke patients
NCT ID NCT07073248
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a non-invasive brain stimulation technique called intermittent theta burst stimulation (iTBS) can improve arm and leg movement in people who had a stroke more than six months ago. 48 participants will receive either real or sham stimulation over 15 sessions in 5 weeks. Researchers will also use brain scans to see if the stimulation changes brain structure and function.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Intermittent Theta Burst Stimulation (iTBS) – a non-invasive brain stimulation device
- What this could lead to
- If it works, this could offer a new, non-invasive way to improve arm and leg movement in people who have had a stroke, even years later.
- What could go wrong
- This is a small, early-stage study (48 people) testing a device, not a drug. The benefits may be modest or not last long, and results may not apply to all stroke survivors.
