Zapping the brain to reconnect with muscles after stroke

This study looks at how the brain talks to muscles in people who have had a stroke. Researchers will use gentle, non-invasive brain stimulation and measure brain and muscle activity while participants squeeze a device with their weak hand. The goal is to see if this stimulation can improve communication between the brain and muscles and help with hand control. About 20 people who had a stroke at least 6 months ago will take part in a single 3-hour visit.
