- Original description
This study is a single-blinded, randomized control study that aims to recruit 48 participants. Participants will be "randomized" into one of the study arms of the study: active stimulation to GPi, active stimulation to DN, or sham stimulation. The purpose of the study is to look into the effects of LIFUS in patients with cervical dystonia. The participation will include seven study visits, at least 24 hours apart. All study visits will take place at TWH. The first visit is a screening visit. Visits 2-6 will be on consecutive days. Visit 7 will be a week from Visit 6 or from your last day of LIFUS, whichever comes first.Read full original descriptionShow less
