Brief Summary:
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.
Detailed Description:
The primary objective of this study is to develop rTMS for FHD. The focus is to assess whether stimulating the PMC or PSC will show greater improvement in writing behavior. This research builds upon prior studies that have demonstrated improvement in behavior after rTMS to PMC and PSC. The study includes five sequential visits:
* Visit 1 behavior writing measures and dystonia rating scales.
* Visit 2 includes task-based functional MRI brain scans to develop cortical target for rTMS sessions.
* Visits 3, 4, and 5: FHD participants receive 10 Hz rTMS to PMC, PSC and sham rTMS to PMC in a cross over design with at minimum one week of washout between sessions. Participants complete behavior writing measures and rating scales on same day before and after each TMS session and an fMRI after each TMS session. Up to 5 Healthy Volunteers were recruited to help develop the TMS visits.
