Official title
Pathophysiological Insights Into STN DBS for Primary Cervical Dystonia
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this research study is to determine the physical brain changes in people with cervical dystonia after deep brain stimulation (DBS) surgery and as compared to healthy controls. We will do this by measuring your body's response to transcranial magnetic stimulation (TMS) before and/or after DBS surgery. TMS is a non-invasive procedure during which you sit in a chair that looks like one you would find at the dentist's office. A nerve stimulator is placed on the wrist of the right hand to stimulate the median nerve; the intensity of the nerve stimulator is gradually increased until the right thumb begins to twitch. A magnetic coil is placed on the scalp on one side of the head, overlying the brain's motor cortex, to stimulate the brain's output to the muscles in the opposite hand. If you are a control subject, and therefore will not/have not have DBS surgery, we will measure the body's response to TMS for comparison purposes. We expect that the electrical differences in the brain may be related to the physical benefits some patients with primary cervical dystonia receive from DBS surgery.
