During an anterior tilt, how does the ASIS move?

An anterior tilt rotates the pelvis forward in the sagittal plane, so the anterior superior iliac spine moves forward (anteriorly) and downward (inferiorly). This forward rotation increases lumbar lordosis and is produced by hip flexor activity pulling the pelvis forward. If the pelvis tilted the other way (posterior tilt), the ASIS would move backward (posteriorly) and upward (superiorly), not forward and down.
