Fig. 4
The change in transverse-plane angular momentum (ΔHz) for each gait phase during A, B straight-line gait, and C, D turns. Positive ΔHz is leftward in the direction of the turn. The left panel A, C provides average ΔHz 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
