Brain Stimulation to Improve Hand Movement After Stroke

This trial is testing whether high-frequency repetitive transcranial magnetic stimulation (rTMS)—a non-invasive procedure that uses magnetic pulses to stimulate the brain—can help people with severe upper limb weakness after stroke. Researchers will use detailed brain mapping to see whether this treatment can activate nerve pathways that may have been dormant after the stroke. The study focuses on patients who have not shown nerve activity using standard testing, even though their brain may still have the capability to regain some function.

Most stroke recovery research has focused on people with mild-to-moderate arm weakness, leaving a major gap in understanding how to help those with severe hand paralysis. This medication or treatment may work by temporarily boosting brain activity and revealing or awakening nerve pathways that appear 'silent' on standard tests, offering hope for a group of patients who have been largely left out of research.
