Effects of obesity and foot arch height on gait mechanics: A cross-sectional study

Fig 2

Group mean ankle and knee joint moments for the right leg.

We plotted the internal ankle plantar-flexion moment (A-1, C-1), internal ankle eversion moment (A-2, C-2), internal knee extension moment (B-1, D-1), and internal knee abduction moment (B-2, D-2) over the stance phase of walking at preferred walking speed (PWS, A-B) and pedestrian standard walking speed, 1.25 m/s (SWS, C-D). Black lines represent the non-obese group, while red lines represent the obese group. Dashed lines represent the normal arch group, while solid lines represent the lower arch group.
