I use it pretty much daily - but about 3 - 5 minutes. I hang without any shoes or boots on, and it works fine for me, but others need a boot or shoe. When I was having a serious back problem before the fusion, it really helped. Sort of like a chiropractic adjustment on your own.

After the fusion, I OK'd it with my PT and MD, and they said fine. It certainly gives one a stretch in a different direction. I think it does no harm, and perhaps some good. I do some "curls" while upside down. I hang fully upside down - that is - the only thing touching is my feet, everything else is loose and free. It taakes a bit to get used to, and to feel comfortable by oneself, At the beginning, I only went over a bit, and had my wife near me.

As far as returning to a stand up position and controlling one's tilt, it is a matter of getting the right balance - the pivot point has several adjustments - and using body weight (mostly the position of your arms - up and down) to control tilt.

When my son with the profound developmental disability was young, he was on a program where we used "suspended inverted roataion - SIR" regularly. Not only was he upside down, we swung him in large circles, etc. This did amazing things to reduce his extreme (at that time) hyperactivity and inability to process stimuli.
