Clinical Validation of DystoniaNet Deep Learning Platform for Diagnosis of Isolated Dystonia

Who May Qualify: 1. Males and females of diverse racial and ethnic backgrounds, with age across the lifespan; 2. Patients will have at least one of the forms of dystonia, including focal dystonia (e.g., laryngeal, cervical, oromandibular, blepharospasm, focal hand, musicians), segmental dystonia, or generalized dystonia; 3. Patients will have other movement disorders (Parkinson's disease, essential tremor, dyskinesia, myoclonus) and other non-neurological conditions (tic disorders, torticollis, ulnar nerve entrapments, temporomandibular disorders, dysphonia) that mimic dystonic symptoms. Who Should NOT Join This Trial: 1. Patients who are incapable of giving willing to sign a consent form; 2.
