So, for DO's to have a place on ER, the producers would have to portray there uniqueness to even have a reason for such an addition to the ER cast. This uniqueness would of course be OMM....but is this a good thing? To the lay public watching the show, they may get the wrong impression that OMM is the only thing DO's do. A large percentage of DO's don't even use OMM. Is OMM even practical in the world of medicine today? A.T. Still created OMM as an alternative form of treatment at a time when mainstream medicine was subpar.
