Left: Boxplots of the step length symmetry index for each participant and condition during the incremental shuttle walk test. A step length symmetry index of 1 corresponds to perfectly symmetric step lengths, while values greater than 1 indicate longer steps with the prosthesis. Right: The estimated changes in absolute step length asymmetry caused by each condition for each mobility group based on the best-fit LMM. More negative values indicate better symmetry improvements, and error bars indicate 95% confidence intervals.
