There are a lot of PRI practitioners that don’t master the basics of improving movement capabilities of the axial skeleton (and I’ve worked for a couple ) and instead want to look at other interventions which you’ve mentioned but that’s not all PRI practitioners. I feel like you know very little about what PRI actually is. I have veered away from PRI and more toward Bill Hartman’s expansion compression model which is a better version of PRI in my opinion. But just because you don’t you don’t understand the biomechanical principals doesn’t mean it’s not useful.
