Gait Parameters. (A) Pressure Profiles. The insole data provide information about the pressure applied at the heel and front-foot and are used to normalize the gait-cycle. The solid blue line indicates the right heel sensor, which starts and ends the gait-cycle once a personalized threshold is crossed. The dotted red line is used to calculate the toe-off event of the right foot using the toe-sensor. (B) Gait adaptation. ND corresponds to non-delayed trials, HD to a mismatch of a half step-cycle, and FD to a full step-cycle. A sinusoidal function (red line) was fitted to the data (y-axis: stride time deviation, x-axis: delay), showing that the variation of stride time deviation is weakly systematic. Participants tend to walk slower for trials that are neither temporally nor spatially congruent. Grey lines in the background represent each individual’s data. (C) The violin plots indicate the distribution of the participants’ mean stride time (MST) for three baselines (BPre, BPost, and familiarization) and the intervention (Interv.) session. Participants’ MST did not significantly change across different blocks. (D) Stride time coefficient of variation (CVST) for three baselines and the intervention block. While the CVST seems to be higher in intervention, no significant difference was observed across blocks
