Fig. 3: Results from 7-meter Timed Up and Go Tests with respect to diary-documented motor states.

a The results of 1917 half-hourly performed 7-meter Timed Up and Go Tests (TUGT) in 51 patients with Parkinson’s disease with respect to Off, On without dyskinesia and On with dyskinesia as documented in the patient diary (left hand side, yellow colour) and observer diary (right-hand side, green colour). b Illustrates absolute variances during the 7-m TUGT in respective motor states. c Displays relatives variances after individual normalization of measured 7-m TUGT times to the mean time achieved by a patient in the respective motor state. Single dots indicate mean values for individual patients, black bars and whiskers represent medians ± interquartile ranges for the entire cohort. *P < 0.05, **P < 0.01 and ****P < 0.0001 from Kruskal–Wallis tests with Dunn–Bonferroni post-hoc tests, corrected for multiple comparisons. ^##P < 0.01 from Mann–Whitney test. 1 (a), 7 (b) and 11 (c) data points are not shown to allow for proper scaling of the graphs.
