  1. aCoefficient of variation (CV) is calculated as the ratio of the standard deviation to the mean. bPVF BW : peak vertical ground reaction force adjusted for body weight change; CSOM: client-specific outcome measures; EDA: electrodermal activity.
  2. Descriptive data are represented as mean (SD).cThe 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.
