During a posterior tilt, how does the ASIS move?

When the pelvis tilts backward (posterior tilt), the whole front of the pelvis rocks upward and back. The ASIS is on the front edge of the ilium, so as the pelvis rotates posteriorly, that point moves toward the back (posteriorly) and upward (superiorly). This backward rocking also tends to flatten the lower back. In contrast, tilting forward would push the ASIS forward and downward.
