- Data are mean ± standard deviation or median (interquartile range)
-
RDIST the root-mean-square (RMS) distance of COP, TOTEX the total excursion of COP, MVELO the mean velocity of COP, AREA-SD standard deviation area of COP, FR no supporting structure, LT light touch of the index finger to a supporting structure (to touch in force < 1 N), DO dependence on a supporting structure for stabilization as desired]
- Significant differences between the young and elderly groups are indicated by asterisks (***p < 0.017). Significant differences between the FR and LT conditions are indicated by daggers (†
p < 0.05, †††
p < 0.017). Significant differences between the FR and DO conditions are indicated by double daggers (‡‡
p < 0.025, ‡‡‡
p < 0.017). Significant differences between the LT and DO conditions are indicated by section signs (§§§
p < 0.017)
