Pelvic Floor Dyssynergia – What Are The Treatment Options? Overview The pelvic floor muscles present in the lower abdomen play an essential role in helping an individual eliminate stool. Most people do this without giving it a second though, as their muscles work in coordination.

It is called pelvic floor dyssynergia and it makes it difficult for a person to have a bowel movement.
