I'm not biased. I look forward to OMM and deciding for myself its value. I have a totally open mind and know several very respectable physicians who have used it successfully. I hope that it proves itself to be a useful tool in med school. However, I also like to see the science behind any touted treatment plan, and so far, OMM has yet to produce. This is why I don't blame MD students who don't buy into it.
I personally did not apply to DO schools because of the OMM aspect. Even though my stats are a little on the low side, I had connections at an MD school that I had a pretty good shot at getting into, yet chose not to apply because I feel that an osteopathic medical school is where I belong. VCOM-CC specifically. The DO philosophy aligns perfectly with everything I've ever believed concerning today's healthcare and the direction it should be going. If OMM turns out to be a way of providing better care for my patients, then that's icing on the cake, but it's not currently the center of my appreciation for osteopathic medicine.
Any medical student, MD or DO, is by nature a student of science, and should not only expect, but also demand, that the backbones of their profession be able to stand the rigors of scientific testing. For DO's, that includes OMM. Unfortunately, other than anecdotal evidence, I have yet to see solid proof of why or how it works. That's not to say it won't present itself in the future, but until then, I have no problem giving a pass to those who view it with a wary eye.
