  1. Values are mean ± standard deviation. Gait direction is the difference of right quiet (RQ) and left quiet (LQ) to the baseline setting. All other parameters are RQ and LQ relative to the baseline setting. The p-values of the statistical analysis (ANOVA) are given in the right table section. The factors volume (v), side (s), the interaction volume*pitch (v*p), side*pitch (s*p), side*volume (s*v), and volume*pitch*side (v*p*s) were analyzed. The level of significance was set at α = 0.05. Significant differences are marked with a*
