Abstract
[Purpose] Focusing on the frequency of going out, this study investigated whether the 3-meter zig-zag walking test (3ZW) is a useful index for assessing the gait ability needed by the elderly for going out. [Subjects and Methods] The subjects were 30 elderly persons aged 65 years or over who were regularly visiting a medical facility. The subjects were classified into two groups, based on their going out frequencies, and logistic regression analysis was conducted using their results in the 3ZW, timed up-and-go test (TUG), and 10-m walking test (10WT) as independent variables. In addition, using the walking speeds of the two groups, the most statistically valid 3ZW cut-off value was determined from the receiver operating characteristic curve (ROC). [Results] The 3ZW was determined to be a variable affecting the frequency of going out. The cut-off value for the 3ZW was judged from the ROC to be 11.1 s. [Conclusion] The results suggest that the gait ability needed for going out can be judged using the cut-off value as a boundary.
