  1. Values are means ± standard deviations or percentages. P-values were calculated using unpaired t-tests or χ2 tests by gender
  2. FoF: fear of falling, 5CS: five-chair-stand test; tandem test: tandem stand test, CV: coefficient of variation, AC: autocorrelation coefficient, VT: vertical, ML: mediolateral, AP: anteroposterior, HR: harmonic ratio
