Oh, Mark Morningstar's Tornado Suit? I'd be interested to see independent peer reviewed studies of that too, if you can find any
I'm a bit wary of anyone connected to the CLEAR Institute as they do make bold claims and (in the past but maybe not so much now) would focus on how awful and terrible spinal fusion surgery is, rather than giving decent evidence that their own treatment works. I'm very open to reading decent research and studies on all of these nonsurgical techniques though, as obviously it would be wonderful to have an effective treatment that doesn't involve surgery.
As far as bracing goes I personally think that the high-profile Milwaukee can be very effective in some cases - however it's just not tolerable for most people to wear for years on end. I wore plaster bodycasts (during winter months) and Milwaukees (during summer months) for eight years - both treatments which some doctors have claimed are "barbaric", but they held my progressive infantile idiopathic double curve in the high 60s/40s for most of those eight years. These were definitely effective treatments in my case, but they're not at all pleasant. It's really good that people are continuing to attempt to design better braces!
