Table 2.
Comparison between various indices of fallers and nonfallers at t1. Data are given under the form median [1st quartile–3rd quartile]. SD = standard deviation, D = fractal dimension. These indices are followed by a subscript labeling the time series from which it was obtained. Results of the TUG test are given in the last line. Significant differences are written in bold font.
