From what everyone else has posted, and if you have read that thread that I linked to in my earlier post, the info is pretty much covered.
IF the cord is wrapped around causing the inability to turn, then the inversion techniques will work well. What they can do is use gravity to float the baby; then when you quickly turn upright again, and all the amniotic fluid whooshes by Mackenzie, it can slip that cord right off of her!
If its not the cord and the baby is just stuck in the pelvis somehow, then inversion techniques can help float the baby up out of the pelvis to give her an opportunity to reposition herself.
But I do really like the stair trick (or something else on your hands and knees - like coffee table to floor or chair or something lower) instead of the ironing board trick; simply because getting on an inclined ironing board on your back and then getting off is a heck of a lot more difficult than being on your hands and knees! Plus you can right yourself quicker (with supervision please) so that the amniotic fluid can really whoosh by the baby. That "whoosh" is a highly technical term, btw. :LOL
Chiropractic will help anatomically to relieve uterine constraint caused by a misaligned pelvis or lumbar spine or tightened ligaments, and it will also help neurologically by positively affecting the neural messages from your brain to your baby and back again, which affects all functions of your body and Mackenzie's body, including hormonal balance.
Any more questions, fire away.
