Figure 6

Dependence of the asymmetry index (AI) of the vGRF distribution at the metatarsal heads of the left and right foot (respectively, A and B) and at the heel of the left and right foot (respectively, C and D) on trunk inclination during linear (LIN), counter-clockwise (CCW) and clockwise (CW) trajectories. In the abscissa, larger negative values (average ± standard error, SE) of AI represent an increase in vGRF on the lateral part of the relevant foot region. In the ordinate, positive or negative values (average ± SE) represent respectively inclination towards right or left side. See text for explanation.
