Disease Duration (yrs, mean ± SD) UPDRS -- Score (points, mean ± SD) SSD Proportion of right answers (95% C.I.)
  Total I II III IV  
7.7 ± 4.1 36.7 ± 19.3 2.6 ± 1.7 15.7 ± 7.6 16.5 ± 6.0 6.3 ± 5.4 0.79 (0.75-0.83)*
  1. UPDRS, Unified Parkinson's Disease Rating Scale (scale maximum 199 points). Subscales in roman numerals: I, Mentation, behavior and mood (subscale maximum 16); II, Activities of daily living (52); III, Motor examination (108); IV, Complications of therapy (23). Higher scores denote increasing disability. SSD, somatosensory discrimination. Comparison with normal volunteers, 0.95 (0.93-0.96, 95% C.I.), unpaired, two-tailed t-test: * p < 0.001. SSD, somatosensory discrimination for object pairs above the critical threshold difference in the major axis of approximately 2 mm
