Statistical analysis
For our statistical analysis, we compared the average step length, stance, and swing time SI values at five different time points: baseline (BL), early adaptation (EA), late adaptation (LA), early post-adaptation (EP), and late post-adaptation (LP). BL, LA, and LP correspond to the average SI values during the last ten strides of baseline, the final adaptation trial, and the tenth minute of post-adaptation, respectively. EA and EP refer to the first ten strides of the adaptation and post-adaptation periods. We checked the normality of all dependent variables using a Shapiro-Wilk test. Data was considered as an outlier if the value was more than two standard deviations away from the group mean. To assess SI differences between and within groups at the specified time points, we implemented a 3 × 5 mixed ANOVA. Significant between-group interactions underwent follow-up simple effects tests using one-way ANOVAs. We used follow-up one-way repeated measures ANOVAs and paired comparisons to determine specific within-group time point differences. We set the significance threshold at p < 0.05 with a Bonferroni correction for simple comparison tests. The researchers and the participants were not blinded for this initial study.
