I➜The Unified Parkinson's Disease Rating Scale, abbreviated UPDRS is a scoring system widely used for the clinical evaluation of Parkinson's disease (PD). Its 42 items are evaluated by interview and clinical observation. Clinicians and researchers alike use the UPDRS and the motor section in particular to follow the progression of a person's Parkinson's disease. Scientific researchers use it to measure benefits from a given therapy in a more unified and accepted rating system. Neurologists also use it in clinical practice to follow the progression of their patients' symptoms in a more objective manner.
A total of 199 points are possible (199 represents the worst disability and 0 no disability).

Note: Hoehn and Yahr Scale and Schwab and England Activities of Daily Living Scale are not included in our online tool.
