in order to prove something, placebos have to be used. Not only do you assess response compared to placebo but you need to compare side effects to placebos.
While sounding promising, we do not know what potentially harmful effects there are.

I know mommd. My point is that using the procedure of injecting the spine with a placebo and inversion tilting the patient is unnecessary.

Find another way to test it. - we all know this procedure is painful, to say the least.
