Physical Activity, Gravity Helps Birth Process
A large search of the literature recently concluded that being upright and walking around during the first stages of labor makes the whole birthing process easier, and leads to less reliance on epidurals for delivery.
Is this any surprise?
When mothers allow gravity to assist in the birthing process, this allows the baby to shift itself into the lesser pelvis, into the pelvic inlet. Then, because there is a rush of the hormone relaxin, the loose ligaments of the pelvic rim relax, and gives more room for the baby’s head to start crowning.
Here’s a side view of a pelvis while standing. There’s not a lot of room to start out! Fortunately, there’s gravity and the relaxin hormone:
Side view of the pelvic inlet and outlet
Looking down, this is a view of the trip out of the belly, through the pelvis. We might need to loosen some of those ligaments to get through. Chiropractic care will help keep the pelvis straight, with no torsion, no tight muscles.
The pelvic inlet.
Here’s the view from the bottom-up. That pointy tailbone (coccyx) is actually pretty flexible, where there’s relaxin in the system. With those cross-hairs, it kind of looks like it’s shaped like a baby’s skull. Do you want to push that out with the help of gravity and a loose pelvis, or would you like to be laying down?
the pelvic outlet
Oh no! the mother is laying on her back, trying to push a large, roundish shape through the pelvic inlet and outlet. She’s got to push UP and over the sacrum because she’s on her back with legs in stirrups. Only she can’t push because they gave her an epidural. Get the vacuum out!
Laying on your back, trying to push out a watermelon.
As you can see, the mother has a mechanical advantage to push the baby out if she is somewhat upright, in a squat to help push out the baby. If she’s on her back, there’s a bumpy ride ahead for the baby with a pelvis that is squished down, making the pelvic inlet and outlet smaller.

Great pictoral view of the pelvic canal. It is amazing how so many medical professionals could overlook the obvious benifits of the assistance of gravity and still rely on stir ups. It seems that when we mess with nature too much, that it has a tendency to bring about the opposite effect. It makes me wonder how many unnecessary irreversible birth trauma’s have occured due to not utilizing the simple biomechanical benefits of gravity. Good post Dr. Lloyd.
I agree with Dr. Trent. And, to answer his question, “too many to count!”
I’m a chiro student studying OBGYN. Thanks much, makes sense.
For those who don’t know, when you go to chiropractic college, you take many of the same classes that medical students take, including obstetrics and gynecology (OGGYN.) In the context of chiropractic practice, it’s important to understand OBGYN for a well-rounded and balanced understanding of how the body works, and it provides a differential diagnosis for when a patient comes in with low back pain that may or may not arise from the organs contained within the pelvis.
