Fig. 4

Location of the cluster markers, pointed landmarks and landmark markers. The marker configuration is a combination of that proposed by the kinematic Rizzoli foot model [43, 44] and the kinetic foot model of Bruening et al. [45]. The figure key differentiates between markers used to define the anatomical model in the static pose, markers used to track the segments’ motion in the gait trials, and markers used for both. Hidden medial markers (i.e., ST and MM) are indicated in parentheses behind their lateral counterparts. The full descriptions of the abbreviations (landmarks) are provided in Table 2.
