I don’t think it is valid to draw a comparison between non surgical treatments of adult scoliosis and creation science. (Almost sounds like a debating tactic that a creation scientist would use, shame on you

)
If someone asks “How do we know the earth is 4.5 billion years old” we can reply with tons and tons of hard scientific evidence.
If someone asks “How do we know you can not correct an adult scoliotic curve without surgery”, well, so far, all I’ve seen is Linda’s one page explanation and Karen’s french paper. Can we do better than that?
The rest of the world pursue conservative treatments (read SOSORT) while here in the states it is primarily surgery. Are the Europeans idiots? Are they gullible? Do they lack good scientific education? I dunno, maybe.
I’m sorry, but when you say
It sure sounds good, but without the evidence, it is no more than a faith statement.
Now, I could give you evidence from SOSORT papers that contradict what you say. We could rip the papers apart for not being rigorous enough. But critiquing the other view without substantiating your own does not necessarily prove anything (another creation science tactic I might add - I know this gets your goat when I say it too

hope you read it with a smile on your face).
Even Lori Dolan, Ms Evidence based medicine herself says
I have read a lot of the literature coming out of Europe concerning physical therapy and bracing. I commend the dedication of these clinicians to conservative treatment and I look forward to reading results of large-scale controlled trials from their institutions. We need as many people as possible working on this question in order to build a solid body of evidence.
She doesn’t say they are wasting their time. It is a little more toned down than the No Way No How response people get here. I still have to go with my “Not likely, but good luck”.
