Should birthers wrap their abdominals postpartum?
There is a lot of talk on the internet about abdominal corsets and binders, which leaves us with the question: should birthers bind their bellies postpartum?
Let’s look at this from an orthopaedic perspective:
When dealing with an ankle sprain or torn ACL, it is a no brainer to wrap, tape or brace the injured tissues to give enough external support for the joint to prevent excessive accessory movement and support the surrounding tissues while the ligaments and muscles heal from the injury and restore function with adequate load transfer.
Now, let’s translate this to the postpartum core:
- We know that:· 100% of pregnant folks will get a diastasis rectus abdominus (DRA) in their third trimester as measured by an enlarged inter recti distance (Mota et al 2014)
- Some people also stretch through the abdominal muscles (Brauman 2008)
- Muscles that are lengthened loose contractile strength as seen on the length tension curve as their maximum force generated decreases (Gordon 1966)
- 45% of birthing folks experience low back pain (LBP) and Pelvic girdle pain (PGP) during pregnancy and 25% postpartum (Wu et al 2004)
- Transversus Abdominis (TvA) is inhibited or delayed during and after low back pain is experienced (Hodges et al 2003)
- Multifidus (MF) is delayed on the painful side of the LBP group (MacDonald et al 2009)
- PGP causes poor synchronization of the deep system (Lee D 2011), especially in PFM and TvA (Bo et al 2009)
- The pelvic floor is stretched and/or torn during a vaginal delivery (Sleep et al 1984)
- 100% of birthing people with a laparoscopic surgery had a DRA (Parker et al 2009)
- Spontaneus healing of a DRA (looking at the inter-recti distance) only occurs in the first 8 weeks post partum, beyond that intervention is needed (Coldron et al 2008)
So it stands to reason that just as cultures around the world have used abdominal binding for centuries, modern day birthers should consider using The Ab System to help restore function to the abdominal wall postpartum.
Remember that an external support to the healing tissues is only temporary and needs to be coupled with restorative exercises to rebuild the internal system.
The following is a list of research we refer to in our work
We are constantly updating this page as newer research is released.
Please note, the studies below include gendered language. At bellies inc., we know that there are gestational experiences by those who do not identify as pregnant women and we hope to one day be able to include studies that reflect this experience.
