Fig. 3. Graphical comparisons of cross-sectional planar analyses of femoral strain distributions calculated for five time increments (% of contact) during representative walking for (A) individual pc05, (B) individual pc03 and (C) individual pc07. Time increments (% of contact) correspond to those plotted in Fig. 2. The centroid of each section is indicated by the black dot. Thin lines indicate contours of strain magnitude (all spaced at 100 µ). Peak strains calculated for these steps are labeled on the sections at either 30% or 50% depending on the individual. Compressive strains are shaded gray. The neutral axis (NA) of bending (strain=0 µ) is indicated by the red line (strain contour) separating compressive and tensile strains. Strain gauge locations are indicated by the black bars around the cortex of the femoral cross-sections. Anatomical directions are labeled in A and reflect the anatomical AP and DV axes illustrated in Fig. 2B.
