Studies have demonstrated that adjusting the pregnant women appears to relax the pelvic floor muscles at rest. As there were no changes seen when they adjusted the non-pregnant comparison group, this finding in the pregnant women appears to be an effect unique to pregnancy.
The pelvic floor muscles are known to have active roles in pregnancy and childbirth, as well as in spinal stabilisation. When the pelvic floor muscles are stressed over time, health issues like incontinence and vaginal prolapses can come up.
We know these are problems with massive emotional, physical, social and financial costs across the world and a significant cause of stress for these women.
For a woman in labour, the ability to relax pelvic floor muscles (as well as contract them) to allow the baby to move through the birth canal is important, especially as the baby crowns.
The primary findings of this study are incredibly encouraging, especially given the fact that quantitatively assessing the effect of spinal adjustment on pelvic floor muscle function has not previously been done.
