Hind limb specimen with bony landmark markers (gray circles) and marker triads (white circles at triangle vertices).

<p>Markers and marker triads are adhered along the pelvis and a single limb. The left hind limb was suspended to prevent obstruction of the right hind limb markers. The right hind limb was manipulated using the rigid extension (identified with a white arrow) attached to the metatarsal bones distal to the tarsus triad. Reflective markers can be seen at the stifle and anterior tibia, but these markers were not used in the current study.
