This is really good news! The more doctors and qualified researchers devote their time to creating good studies, hopefully Schroth will be taken much more seriously by medics in the future and it will be seen as a suitable treatment to try for those with moderate curves or who are on the cusp of surgery. I'm glad that other nonsurgical treatments such as the work done by SEAS and side-shifting too, though I had it direct from Min Mehta that side-shift alone will not permanently correct a surgical-sized curve. I'd like to see more work done on torso rotation too.
We desperately need more doctors and medical facilities to take all this seriously, as there are only a few individual, officially Schroth qualified physiotherapists in the UK and as such official Schroth therapy can be hard to access, and they are mostly working as individuals within their own tiny private physio practices.
It is actually a myth that Schroth has long been a standard treatment for scoliosis in European countries. Schroth is available if you know to track it down, but again it can be hard to access. There are 3-4 clinics in Germany but even there, the country in which it was devised, it is seen by the medical establishment as very much a "fringe" treatment. Aggressive bracing is much more of a standard treatment there.
Anyway, this is fascinating stuff - thanks for posting it!
