There have certainly been a lot of discussions on the validity of certain therapies and articles and doctors, etc... Here's a comic I came across about article language. I'll admit to at least five of these. The last one is particularly appropriate for scoliosis research.

As a side note, if you are in grad school, or have ever been in grad, or will ever be in grad school, you need to check out PhD comics. It's not really an overstatement to say that it helped me get through grad school. So funny and so true.
