Figure 3.

A, Vertical ground reaction forces and, B, mean difference curve of the braced and nonbraced conditions. A, Mean ensemble waveforms plotted over the stance phase of walking for mean vertical ground reaction force normalized to body weight for both the braced and nonbraced conditions. B, Corresponding pairwise comparison functions and associated 95% CIs (gray bands) indicating the mean differences between the braced and nonbraced conditions. Differences between conditions exist when the 95% CIs do not overlap zero.
