Relationships of cranio-caudal/medio-lateral navicular displacements (NCC/NML) to forefoot to hindfoot (FFtoHF) rotations.

(a) Averages among participants with standard deviations for FFtoHF plantar/dorsiflexion, adduction/abduction and pronation/supination during the stance phase (SP). Corresponding ranges of motion are given in Table 2. The blue parts represent the absorption and the red parts the generation phases. (b), (e) Displacement-displacement diagrams of mean FFtoHF rotations versus mean NCC (b) and mean NML (e) with median cross-correlation coefficients for the whole stance phase (Xc), the absorption phase () and the generation phase () in the titles. (c), (f) Scatter plots of cross-correlation coefficients for the whole stance phase (Tot), the absorption phase (Abs) and the generation phase (Gen) from all participants for the relationships presented in rows 2 and 4. Large markers represent the medians. (d), (g) Distribution of the cross-correlation coefficients among the strong, moderate and weak classes (values given in Table 3).
