Bill Hartman's Weekly Q&A November 3, 2019 Podcast
Otherwise, you're going to probably end up in a little bit of a lawsuit because that's really intrusive. You're getting into some very personal area there. So what we're going to do is we're going to make an estimation of what that IPA is by all other numbers. So now let's go to the first half of that question. Does an IPA mean a narrow ISA? In general, from a structural standpoint, yes, they will be similar, but they should move in opposition during normal breathing. And so that's what we're talking about when we're talking about making an estimation of the infrapubic angle. So if I measure the ISA, the infraternal angle, my assumption is that I actually have a narrow infrapubic angle as well. However, if I identify a limitation in extremity range of motion, that would be indicative of somebody that does not have the full breathing excursion, which means that they have a compensatory strategy. So this is where we get into the two archetypes of the inhaled axial skeleton versus the exhale axial skeleton. So if I have somebody that measures with a wide ISA with a limited breathing strategy, then I know that I have an axial skeleton that's biased towards exhalation with an inhalation compensatory strategy at the ISA or vice versa, where I have the inhaled axial skeleton with a compensatory strategy at the ISA, which would be your narrows. So structurally, yes, they would match mechanically during breathing. They should move in opposition. And under certain circumstances of compensatory strategy, they will be matched again. But this is due to the restriction of the compensatory strategy. So Josh, I hope I answered that question for you.
