Summary

This study tests whether a rapid form of brain stimulation (accelerated TMS) can improve hand function in people with focal hand dystonia, a condition that causes muscle cramps during tasks like writing. Twenty-one adults will receive four TMS sessions in one day, and researchers will track changes in writing and brain scans over 20 weeks. The goal is to ease symptoms and understand how TMS affects the brain.
