Line graph showing symmetry ratio in percentage of baseline across four conditions: NW, AVF-1, No AVF-1, AVF-2, and No AVF-2. Data for stance time (purple), push off force (red), and plantarflexion (cyan) hover around target values with variability. Green zone indicates target range. — Evolution of symmetry ratios $δ_{S T}$ , $δ_{POF}$ and $δ_{APL}$ during AVF on ST, POF and APL respectively. The symmetry ratio was averaged every 10% of each phase for each participant, before taking the mean over all participants. NW: Natural walking. AVF: augmented feedback. n is the number of participants used in the analysis. The error bar is the standard deviation of the mean.
