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.
