Brain Stimulation to Improve Hand Movement After Stroke

This trial is testing a new type of brain stimulation called multisite high-definition transcranial direct current stimulation (HD-tDCS) to help stroke survivors regain arm and hand function. Unlike older brain stimulation methods that target just one area of the brain, this new approach targets multiple connected regions of the brain at once, based on each person's unique brain scans and injury pattern. The goal is to help the brain rewire itself and recover better motor control.

After a stroke, people often struggle to regain arm and hand movement because their brain needs to reorganize and form new pathways. Traditional brain stimulation treatments focus on only one brain region, but research shows that targeting multiple connected brain areas at the same time may be much more effective at promoting recovery.
