Subjects Needed for Focal Dystonia Research

The Non-invasive Neuromodulation Laboratory at the University of Minnesota is conducting a research study titled: Multimodal Assessment of Neurophysiology in Focal Dystonia. The purpose of the study is to use magnetic resonance imaging (MRI) and transcranial magnetic stimulation (TMS) to determine the structure and excitability of the brain between healthy subjects and those diagnosed spasmodic dysphonia or a focal dystonia to gain a better understanding of the cause of the disorder. TMS is a safe, non-invasive, painless procedure which allows researchers to measure the excitability of portions of the brain.


  • Ages 21-75
  • Symptoms of spasmodic dysphonia or a focal dystonia
  • No history of seizure within the last two years
  • Participation includes two sessions lasting 2-3 hrs.
  • At the completion of the study you will be paid $200
