During rotation of the pelvis to the right or left, which statement describes the ASIS positions?

When the pelvis rotates, the ASIS landmarks no longer line up in the same horizontal plane. The rotation occurs around a vertical axis, so the ASIS on the side toward which you rotate moves forward while the opposite ASIS moves backward. This creates a clear anterior-posterior relationship between the two ASISs, rather than them being aligned or being at different vertical heights. Vertical position doesn’t change with this rotation, so describing one ASIS as anterior to the other best reflects what happens during right or left pelvic rotation.
