Figure 2


Fig. 2. (A) Shifts in the orientation of the neutral axis (NA) of femoral bending at five time increments (% of contact) through the step for four individual cooters. Each data point represents the angle of the NA to the anatomical anteroposterior (AP) axis of the femur averaged over N=3–6 steps. (B) Schematic femur cross section illustrating NA orientation and shift. Strain gauge locations are indicated by the black bars around the cortex of the femoral cross-section. Solid red line is an NA with an orientation of 60°. Directions of bending are indicated with respect to the anatomical axes of the bone as described in the text, not in an absolute frame of reference. AP, bending about an NA running from the anatomical dorsal to ventral cortex; DV, bending about an NA running from the anatomical anterior to posterior cortex.
