I think I've found a scientifically-based system. It's based on anatomy, and uses pressure plates to establish how people move their weight when they stand and walk.
It might be a bit measurement based but that alone doesn't mean it's science-based. As far as I can see the author doesn't hold an academic degree and doesn't even think that it's important to have somebody with an academic degree recommend his method if you look at the testimonial page. I don't see references to published papers on the website.
Of course that doesn't mean that the knowledge in the book isn't useful. On the other hand it doesn't help with sanctioning treatment as evidence-based and getting them covered by mainstream medical providers.
As per a recent comment this thread is meant to voice contrarian opinions, that is anything this community tends not to agree with. Thus I ask you to post your contrarian views and upvote anything you do not agree with based on personal beliefs. Spam and trolling still needs to be downvoted.
