Locomotion is an essential component of independence and well-being at old age. Performance deficits in the gait of older adults most often become evident on multisurface and varying terrains. Research results substantiate that falls occur in everyday movement situations that are characterized by instability. A test track, the Multisurface Obstacle Test for Older Adults (MSOT), was developed to diagnose individual performance. The 10-m track consists of different obstacles and varying surfaces, which represent everyday movement situations in a compact way. Twenty-nine untrained, healthy older adults (11 men, 18 women) were tested on three different days at 1-week intervals in a testetest design by the same conductor. Mean age of the participants was 68.85.3years with a mean body mass index of 24.42.5kg/m2. The measured outcome variable was the required time (seconds) on the MSOT. The feasibility for the tested sample of untrained older adults was very good. The MSOT was undertaken safely by the participants, and no falls occurred. The range of the mean for time was between 8.121.53s and 9.001.62s. Regarding intertrial reliability, mean differences (MD) of 3.39 to 5.52% and coefficients of variation (CV) of 2.72 to 4.19% between the first and second trials and MD of 0.69 to 0.85% and CV of 2.57 to 4.54% over the three test sessions were observed. The correlation coefficients between the sessions were .9298. There were significant differences (p<.05) between the first and second trials of each session and between the first and second sessions. The smallest detectable differences (SDD) revealed that a small improvement is enough to detect changes in performance in the MSOT. Selecting tasks from real-life situations of older adults contributes to substantiate practical usability of the MSOT. The measured time on the MSOT showed high relative and absolute reliability in the target group of older adults between 60 and 80years.
