Summary

This study tests whether a gentle electrical current applied to the brain (tACS) can improve hand movement in people who had a stroke more than 6 months ago. Researchers will use brain scans and EEG to see how the stimulation changes brain activity. 45 participants (including healthy volunteers) will receive two different stimulation frequencies and a placebo in random order.

What this could mean

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

Active substance: transcranial alternating current stimulation (tACS)
What this could lead to: If successful, this could point toward a new way to improve hand movement after stroke using brain stimulation.
What could go wrong: This is a small, early-phase study focused on understanding brain activity, not testing a treatment. The stimulation is short and may not produce lasting benefits.
