The study will be an open-label, prospective study. Patients with a diagnosis of cervical dystonia will undergo 4 weeks of baseline evaluation, followed by a 12-week treatment period. Subjects will be evaluated in-clinic every 4 weeks. Standardized assessments will be performed at these visits. Data will also be collected from wearable IMUs (inertial measurement units) and analyzed for improvements in involuntary, repetitive movements and postures.
