Figure 1

Test-retest repeatability of each of the eight anatomical regions of the foot (A). Intraclass correlation coefficients (ICC) obtained from 50 consecutive steps performed under each trajectory (linear; CW, clockwise; CCW, counter-clockwise) for the 4 output variables (peak force, B; peak pressure, C; contact area, D; stance duration, E). In the bottom insets, the grey foot is the right foot; this is the Foot-In for CW, and the Foot-Out for CCW. ICC values are obtained from the average of left and right foot in the case of linear trajectory, and Foot-In or Foot-Out in the case of CW and CCW. Each colour corresponds to a range of ICC value equal to ± 0.02 around the depicted mean value. L, lateral region of foot; M, medial region of foot.
