  1. In total, we identified 3 outlier trials in 3 response variables (i.e. perceived difficulty, prosthesis-side peak braking force, intact-side peak hip power). However, the inclusion/exclusion of these identified outlier trials did not affect the significance of our results (below), so we did not exclude any trials. Because these outlier trials were not outliers in any other response variable, the removal of identified outliers may remove valuable information from this study as a whole
