Can zapping the brain restore hand function after a stroke?
NCT ID NCT07605039
First seen Jun 24, 2026 · Last updated Jun 24, 2026
Summary
This study tests whether a gentle electrical brain stimulation technique called tDCS, combined with hand exercises, can improve hand movement in people who had a stroke. Fifty-six participants will receive either real or sham tDCS for 20 sessions over four weeks. MRI scans will look at brain changes, and hand function will be measured before, after, and at six months.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
transcranial direct current stimulation (tDCS) device
What this could lead to
If it works, this could point toward a non-drug way to improve hand movement after stroke, using brain stimulation and exercise.
What could go wrong
This is a small, early-stage study (56 people) testing a device, not a drug. Results may not apply to all stroke survivors, and the benefit may be modest or absent.
