The Unified Dyskinesia Rating Scale captures the essential features of dyskinesia in Parkinson’s disease within a single scale, including patient perceptions, time factors, anatomical distribution, objective impairment, severity, and disability. The scale addresses the issues clinically pertinent to physicians dealing with dyskinesia in clinical and research settings as well as the issues clinically pertinent to patients experiencing dyskinesia.
