What causes the pelvis to tilt forward during pregnancy?

Rick Olderman
Physical Therapy
It's important to understand that the pelvis can develop an anterior pelvic tilt (position that results from tilting forward of the pelvis, usually due to weight of fetus during pregnancy) even if the muscles in the front of the pelvis don't tighten up. In about 10 percent of people I treat, I've seen the pelvis just "fall" into an anterior tilt due to poor abdominal control and perhaps lumbar spine hypermobility (excessive joint movement).

Standing with straightened, or locked, knees pitches the pelvis into an anterior pelvic tilt. This posture promotes further back extension, in the form of an increased lumbar lordosis (natural inward curve of the lumbar and cervical spine), which causes back pain.
