It is great that Jessie has been doing so well with her Schroth. I believe Beanstalk's daughter has also been doing very well under the guidance of Joanna Slup
You are (as far as we know) the only SSO members who have been to her, and both of you have given very favourable reports about her, which is very encouraging. She is certified by the Schroth clinics, continues to update her knowledge, and her clinic is regulated so patients are protected should something go wrong - this all sounds good to me!
My post here was in reference to adults who are suffering with pain, rather than children. There are a lot more options available to adults with chronic pain - and the three weeks I spent on the programme in Oswestry did include intensive physio, hydrotherapy, pilates, and yoga with an emphasis on building core stability and strength, as well as a lot of education about a variety of issues.
As you say, I don't believe anything like this exists for children, which is a terrible shame. For adults like CurvyClaire though, who have stable curves but are living with chronic pain, things are available on the NHS, and I do think it would be worth looking at these first in case help can be had for free before considering paying thousands of pounds privately.
