Hello  Ponmathi

I used to work with patients with pelvic floor dysfunction, but as I was a nurse not a physiotherapist, this is a little beyond my knowledge level, but is an interesting topic. I hope there is something relevant here for you:

This might be useful but I have not been able to access the full text:

Hi Mary,

Thank you so much for your interest and these articles are verymuch informative.

Pelvic floor stability depends on: 1- healthyt stable collagen chasias of the pelvic organs and the pelvic floor second stratum with its condensations (the pelvic ligaments). 2- healty intact internal urethral sphincter (IUS),, internal anal sphincter (IAS), healthy intact vagina and heathy intact pelvic ligaments.3- intact reactive nerve supply ( afferent somatic, CNS nerve centres, intact thoraco-lumbar alpha sympathetic nerves).

If sacroiliac joint dysfunction is a part of injury to one of those factors or leads to injury of one or more of them then this leads to pelvic floor dysfunction.

I hope my efforts to explain the relation is successfu.
