Damn, that video has 5 million views! I thought it was pretty creative, albeit intentionally a bit goofy.
My school wasn't old-model sublux heavy...and that was 20 years ago. I think much of the BOOPer stuff is based on a combo of some older chiros out there who haven't taken the time to update on the science (and therefore is a dying breed), along with the fact that it's simply easier (and quicker) to use that model when talking to patients. Does that make it right? No, but at least the patient comes away with some conceptualization of what their chiro is doing. I think all practitioners simplify things to some degree when explaining a treatment or disease or drug or whatever to patients.
When a patient says to me that something is "out" and "needs to be put back in", honestly I use my judgement as to the level of comprehension I think that patient is capable of. I frequently will respond something like "well, that's not really how it works, but as long as we're getting you better..." or whatever.
If you think about it, I'm sure you guys can think of some short-cuts and dumb-downs you use to explain things to your patients.
