You sound angry PsychMD, maybe your hostility towards new medical techniques stems from a troubled childhood...

Or maybe you are just mad that you didn't make it into a DO school yourself and subconsciously know that your education was lacking.
All poking fun aside I don't intend to change your mind PsychMD, but maybe you will think twice next time before being so rigid.
The interesting dilemma for cranio-sacral treatments is that they cannot undergo a double blind study. The practitioner would know that they were giving a sham technique thus resulting in a bias error. Imagine if new surgery techniques had to undergo such a study, I doubt anyone would want to volunteer for a double blind cardiac cath.
I have watched as OMT has relieved headaches, backaches, and vertigo. I have even seen someone regain repressed memories and have an emotional breakthrough right on the OMM table. These things I have seen even in my impressionable third year, with "zero" experience. They are interesting to me and as such I intend to explore them further.
Good luck to the "Psychiatrist in Training"
