Can zapping the brain boost stroke recovery?
NCT ID NCT07433972
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study will test whether mild electrical brain stimulation, combined with physical therapy, changes brain activity in people who had a stroke. Sixty participants will receive either direct or alternating current stimulation during rehab sessions. Researchers will measure blood oxygen levels in the brain to see if the stimulation helps recovery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- transcranial electrical stimulation (tDCS and tACS)
- What this could lead to
- If successful, this could reveal how brain stimulation enhances rehabilitation after stroke, potentially guiding future therapies.
- What could go wrong
- This is an early-stage observational study with no treatment outcome measured yet. Results may not lead to direct clinical benefits.
