The UPDRS is a clinician-based scale used to assess the longitudinal course of PD. Two of the six sections were assessed (Part II, Activities of Daily Living (ADL); Part III, Motor Examination). Both consist of a number of items (ADL, 13 items; Motor Exam., 17 items), and each item has a choice of 5 responses that are numerically scored 0-4, with 0 as the least severe response and 4 as the most severe response. ADL final score is a sum of the 13 items and may have a value between 0 (no impairment of overall activities) and 52 (severe impairment of overall activities). LTT, long-term treatment.
