The Open-knee chest helps back the baby out of the pelvic brim and start again in a better position.
- In pregnancy? Only for breech babies!
- In Labor? Only for jammed babies in labor, not for babies still floating!

Sometimes a posterior or asynclitic baby is jammed in the brim of the pelvis stalling progress. Penny Simkin, physical therapist, childbirth educator and doula, teaches us the Open Knee-Chest correctly.
Penny asks, "Wouldn't it be nice to back the baby up and start over?"
What is the Open Knee-Chest position for Labor?
The Open knee-chest position is a maternal position. It is not about making the knees wide apart.
Open knee-chest is an inversion (person's bottom is higher than their head) which opens the angle of the symphysis away from the spine, making the entrance to the pelvis larger front to back. Lovely. Contractions can then rotate the baby.
When to do an Open Knee-Chest
Open knee-chest can be used in
- Pregnancy to help reposition a breech presenting baby, and in
- Labor to help reposition a head down baby whose head is inadvertantly locked in the brim or midpelvis.
In Pregnancy, this position was used to help breeches flip to become head down. It worked fairly well. See details below.
In Labor, its used with contractions that are strong and rather close. The birthing mother is working hard and it seems that the baby just can't rotate and can't descend.
The indications may be
- Back labor without progress
- Strong contractions without progress, even without back labor
- Pain in the pelvic girdle (so it could be hip pain or one-sided pain) in labor
- No pain but no progress either yet there are regular contractions. They may be strong but they aren't getting stronger and closer together.
- A known posterior or asynclitic position without progress
- Baby stuck in the brim, the pelvic inlet
- Baby stuck at the ischial spines, the mid pelvis.
When not to do an Open Knee-Chest:
:Don't do Open Knee-Chest when the head down baby is NOT engaged and floating!
Don't do inversions for women at risk of stroke, who have high blood pressure which warrants medical supervision.
How to do the Open Knee-Chest position
There is a level of commitment to make this technique work. The birthing woman should be told that this is an effective position but requires she be in this position for about 40 minutes (sometimes less). This allows the spaces between the contractions to let the baby back up about 1 centimeter and let's the contractions have a chance to rotate the baby to a better position.
This is why the mother is in this position through and between contractions.
The mother gets into the Open-knee chest for 40 minutes during active labor
To make it easier, a helper can sit in front of the mother so she can brace her shoulders on the helpers ankles!
Some doulas and midwives suggest the Open Knee Chest for a stall in a labor for which the baby is high. Ask your care provider if there is any reason you wouldn't want to be upside down in the inversion or Open Knee Chest, such as abundant amniotic fluid and a loose abdominal tone which could risk a baby flipping breech. Uterine contractions will help prevent such a flip, and help the baby rotate to a left occiput transverse (left occiput lateral for UK, Aus, and NZ readers) position. The baby can then tuck his or her chin (flex, flexion) and engage more easily.
The Open Knee Chest means the knees are away from your pubic bone.
The "Open" doesn't mean that your knees are far apart. They are simply hip width apart.
"Open" means there is a wider distance from your spine to your pubic bone! Your knees are as far apart as your shoulders are, so not very far apart. In this photo, Physical Therapist and DONA founding mother, Penny Simkin shows us the correct way to do the Open Knee Chest position.
You can use a Rebozo like reigns around the mother's THIGHS to support her weight while she rests in this position and lets the baby reposition. The rebozo is NOT on the abdomen or the baby. It is wrapped on the thighs to hold some of mom's weight. (Right.)
Before doing an Open knee-chest:
Is baby engaged? Do engagement actvities first.
Balance before Gravity- do the sidelying release!
Next, after doing the Open knee-chest:
Follow this challenging inversion by a shower, perhaps, bending the knees and leaning forward, resting the arms on the wall of the shower. Or,
lean and rest your upper body on a dresser while your knees are slightly bent and you can sway your hips to relax your muscles.
