Statistical analysis was performed using IBM SPSS Statistics for Windows (Version 22.0). Data were presented as mean ± standard deviation. Descriptive statistics were calculated for all outcome measures. Mean differences within the groups in the functional tests and stabilometric outcomes were estimated using paired sample t-tests, while mean differences between the groups in these variables were estimated using repeated measures analysis of variance. Differences were considered significant at p < 0.05. To determine the magnitude of the interactions between time and group, the effect size or µ2 was calculated as described by Cohen (1998) and interpreted as small (> 0.01 and < 0.06), moderate (≥ 0.06 and < 0.14) or large (≥ 0.14).
