This study aims to apply a non-invasive brain stimulation technology called repetitive Transcranial Magnetic Stimulation (rTMS) in patients with focal hand dystonia (FHD). The goal of the study is to identify which cortical target (premotor cortex (PMC) or primary somatosensory cortex (PSC)) will show benefit after active rTMS compared to sham rTMS. A secondary goal of the study is to understand if 10 Hz rTMS can show behavioral benefit compared to sham rTMS. The study will evaluate rTMS response using measures if writing on a sensor tablet, examiner and patient dystonia rating scales and brain imaging scan (functional MRI) to understand brain changes after rTMS. Safety measures include adherence to TMS guidelines and thorough medical screening to prevent seizures.
