Dear somasimple, off course you are an open mind or you never loss your time with such discussion. First of all I don´t use any one of this méthodes (maybe something of Busquet...), second I don´t believe in wonderful méthodes who solves everything or every cases. What I mean is that kind of therapies (manual therapy in general) comes or from medical doctors or from the so called "Alternative Medicines" (ostheopat.,chirop, etc...) and in this second group is not normal to use the cientific méthode, controlled studies, etc. So for many years a lot of "thécniques" are developed only in clinical basis. That not means it does not work, only never been study as they should because many of the praticioners simply used because it works...
About the knowlegde for all community, normaly the authors of the thécniques (father of the child) made books, manuals and courses. (A good business I must say, but its the same with all authors).
Publishing to prove anything so became important in last 20 years with the Evidence-Based theory, in the 50 before publishing are only good for authors and his curriculum, and remember that "alternative people" are good because solve problems not because write scientific articles, his curriculum are made in clinical field.
Sorry about so long post, but I like you understand that I want too, good studies in all fields of our practice that proven everything we do, but it does mean that things that are not proven yet are not good. besides don´t exist any study that prove they are a waste of time

Best regards
