The Psoas (so-as) muscle is one of the most functional and crucial muscles our body has when it comes to movement in everyday life, and especially during pregnancy and postpartum. It is the deepest foundational core muscle to our bodies. The Psoas is attached to and down your vertebrae, then through your pelvis and end at the top of your femur bone.
With the Psoas, we are able to bend at our hips in flexion, but it also keeps our trunk and spine stable during any other type of movement. Most importantly in relation to birth, the psoas helps to keep our pelvis open and free to move in the way our body needs, it stabilizes. If your psoas is tight or short, it could tilt your pelvis forward, if your psoas is stretched too far or weak, your pelvis could be tilted backwards, causing low back and leg pain. In either situation, it can become a snowball effect in pregnancy, and could possibly lead to a C-section if a doctor does not feel your pelvis is in the right place to get the baby through the birth canal.
