PVF_{BW} |
3.9 (2.2) | 3.6 (1.8) | 4.0 (3.2) | 0.19 (0.82) |

CSOM | 11.3 (16.3) | 5.7 (12.1) | 3.9 (10.5) | 0.94 (0.34) |

EDA | 15.6 (14.4) | 11.4 (12.7) | 10.7 (8.6) | 16.76 (< 0.001) |

^{a}Coefficient of variation (CV) is calculated as the ratio of the standard deviation
to the mean. ^{b}*PVF*_{BW}: peak vertical ground reaction force adjusted for body weight change; *CSOM*: client-specific outcome measures; *EDA*: electrodermal activity.

Descriptive data are represented as mean (SD).^{c}The mean CV were considered not variable at each time point, when time did not exert
a significant effect with P-value higher than 0.05.
