Fig. 3

The average global X-axis force (F_x,avg) for each gait phase during A, B straight-line gait, and C, D turns. Negative F_x,avg is leftward in the direction of the turn. The left panel A, C provides average F_x,avg for each gait phase, each trial, and each participant. In the right panel B, D, each circle indicates the average value for each participant across multiple trials and the bar represents the across-participant (group) averages. Horizontal lines with p-values indicate statistically significant differences between gait phases at the group level, those in gray are significant differences that were not related to the hypotheses
