About the trial

What the trial wants to find out

This study aims to investigate the impact of accelerated transcranial magnetic stimulation (TMS) on brain function and behavior in patients with focal hand dystonia. Previous research demonstrated that individualized TMS improved dystonic behavior after one session. Building on this, the current study administers four TMS sessions in a day, with assessments conducted in four weeks, twelve weeks, and 20 weeks after each session. The research involves 8 in-person and 6 virtual visits focused on functional MRI brain scans and writing behavior analysis. The potential risk of seizures from TMS is mitigated through careful screening, adhering to safety guidelines. The study's main benefit is enhancing dystonic behavior and deepening the understanding of brain changes caused by TMS in focal hand dystonia, paving the way for further advancements in clinical therapy for this condition.
