Fig. 1. A lateral view of the left hindlimb skeleton and pelvis of an adult emu with representative mid-shaft cross-sections for the femur and tibiotarsus (TBT). The gauge positions in the cross-sections and at the femur and TBT mid-shafts are indicated with black rectangles. On the hindlimb skeleton, the gauge position for the medial TBT is indicated by a hatched rectangle on the lateral surface. The kinematic markers analyzed are indicated with black circles and are as follows: the ischium, hip, knee, ankle, tarsometatarsal-phalangeal joint (TMP), and the distal end of the middle toe.
