Ear and Neck Nerve Stimulation for Stroke Arm Recovery

This trial is testing a non-invasive treatment called transcutaneous vagus nerve stimulation (tVNS) to help people recover better after a stroke. Researchers want to compare two approaches: stimulating the vagus nerve through the ear or through the neck, both combined with targeted arm exercises. The goal is to see which approach helps improve arm function, thinking, and overall quality of life in people in the early recovery phase after stroke.

After a stroke, many people struggle with weakness and reduced function in their arms and hands, which affects their ability to do everyday tasks and work. Current rehabilitation methods help, but researchers believe that stimulating the vagus nerve—a major nerve in your body—might boost recovery by helping the brain heal better, especially when combined with exercise.
