95% Confidence Interval with Bonferroni adjustment for multiple comparisons. Analyses included repeated measures’ ANOVA with neutral as reference condition, and pairwise comparisons with Bonferroni confidence interval adjustment. BWS=Body Weight Support. Neutral setting indicates frame bar is placed at hip height.
