Summary

This trial studies the effects of a type of brain stimulation on people with focal hand dystonia to improve behavior and understand brain changes from the treatment.

Who is the study for?
This trial is for adults over 18 with isolated focal hand dystonia, confirmed by a neurologist. Participants must be right-handed, able to give informed consent and literate. Excluded are those with other movement disorders or seizure history, recent drug use or certain treatments like TMS therapy, botulinum toxin injections, specific medications for dystonia symptoms, and recent hand therapy.
What is being tested?
The study tests accelerated transcranial magnetic stimulation (TMS) on patients with focal hand dystonia. It involves four TMS sessions in one day and assesses the impact on brain function and writing behavior immediately after, at two weeks and twelve weeks post-treatment using functional MRI scans.
What are the potential side effects?
While TMS is generally safe when following guidelines, the main potential side effect of concern is seizures; however, risks are minimized through careful participant screening and adherence to safety protocols.
