To confirm the relative and absolute reliabilities of 3 tests: the 5-m Walk Test (5 MWT), Timed Up & Go Test (TUG), and 10-m Walk Test with Obstacles (10 MWT-OB), 18 outpatients with Parkinsonʼs disease were assessed using them. These 2 types of reliability were calculated using the intraclass correlation coefficient (ICC) and Bland-Altman analysis, respectively. The ICCs for 5 MWT, TUG, and 10 MWT-OB were 0.97, 0.94, 0.89,respectively. There was no systematic error for 5 MWT or TUG, and the minimum detectable changes were 0.6 and 1.8 seconds, respectively. In contrast, there were fixed errors for 10 MWT-OB, and the range of allowable error was 0.1 to 2.9 seconds. Thus,5MWTand TUG were highly reliable to assess patients with Parkinsonʼs disease, whereas the relative reliability of 10 MWT-OB was sufficient, but its absolute reliability was insufficient, as there were fixed errors, and second measurement values walking speeds tended to be higher than the first ones.
