I start doing this right oblique and I can keep shoving that right oblique forward. I have space that I can do that. I can lose all of my internal rotation by shoving you all the way forward.

All right. So I was in my head, and I get a little bit confused about the difference between more that kind of flatter oblique turn from like the left side versus up and over to the right side. And yes, I guess I was just kind of wondering if you can kind of clarify that difference.

Yeah, sure, absolutely. It's fairly straightforward. So both are defending against an internal force that's trying to turn you. That's the one thing that you have to recognize is that both strategies, they're going to be idiosyncratic, so it's going to be a structurally driven decision. But again, both are defending against the same force. So this is an internally driven force that's trying to knock you off your feet to your left. Again, we don't really have a choice in that regard unless your internal organs are flip-flopped and then it goes the other way. Again, it's just a bias. All right. And so when we were talking about, so I have to have some way to manage something that's trying to push me this way. The way I was describing it is if you're standing in a really strong current in a river and that river is trying to knock you off your feet to your left, what would you do? Well, you would turn into the current.

Gotcha.

So that's all this is is just a strategy. Okay. And then how tall are you? I'm 62. Okay. So you're taller than me. So it stands to reason that my strategy and your strategy would be somewhat different just because of our physical structure, correct?

62.

Okay. So you're taller than me. So it stands to reason that my strategy in your strategy would be somewhat different just because of our physical structure, correct?

Right.

So you're going to turn differently than I am. And that's all we're talking about. So what we want to do is we want to represent the extremes, knowing full well that there is an infinite number of possibilities in between those two extremes. So one extreme would be for me to just take this and then just turn it, actually just turn it like that. And so this is going to be a very flat kind of a turn. But what that does is it gets the paddle in the water out in front of you, basically. That's what it does. So it pushes that sucker forward like that.

And would that be kind of similar to if it was like a posterior or lower compressive?

Yeah. So that's representative of a later propulsive strategy. Later propulsive strategy. Absolutely. Yeah. Because I got to push it out there. I got to get a way to turn. I have to create a term. And so when you think about late propulsion, so what late propulsion does is it turns the sacrum away. So if I need to turn the sacrum into the current, so to speak, I got to push it out there. So what's the best way to do that? Well, under certain circumstances, it's going to be use a late propulsive strategy, which is why you see a lot of people in that that late propulsive strategy. Okay. Now, there's another way that I can do that. Instead of grabbing in with the posterior lower down here, I grab right there where my middle finger is. If I do that, what happens is this side goes up. You see it? See how it goes up? Right. Okay. And so it goes up, but it still turns the sacrum. I still achieve my goal of turning the sacrum to the right. To the right. Yeah. And so that's the difference. But again, these are different representations of muscle activity in regards to how the pelvis is going to behave. So I still get my turn, right? But now you can see that I'm tilting the sacrum on much more oblique axis, which is why I just call it a right oblique orientation. So you see the difference in the two? Yeah. Yeah. And so if you look at some of the differences, when you see somebody in the flatter turns, because I'm using this posterior, this lower aspect of the musculature down so low, I'm going to see these people. So these are the people that lose early hip flexion. These are people with a lousy straight leg raise. These are people with that lack internal rotation. This guy is still going to lose internal rotation by traditional measures, but chances are he's going to have a better straight leg raise and he's going to have early hip flexion.

And then the right side, we probably have a loss of some of the ER measures.

Greg, because I'm tipping up and over this right hand side here. So I'm tipping up and over. So I'm going to lose my ER. I think that's just, and I've just been given this profile view. So if I push up and over and I push that hip forward, look at all this musculature that changes its orientation from ER to IR.

Correct. So now that you have the two extremes in your head, the thing that you have to recognize is how many possibilities are in between the two.

But the rules are the same, right? So as long as you understand the two extremes, it's kind of like looking at a wide ISA archetype and a narrow ISA archetype—those are the two extremes. Everybody's in between there, right? And every once in a while, you're going to get those really outlier people who are way out on one side. It makes it slam dunk easy: 'Oh, this is going to be, you know, you get one of those people with the gigantically wide ISAs that can't close it at all.' And you go, 'Okay, I know exactly what to do here.' Then you go to the other extreme and get the person who walks in and you can get your thumbs between their ribs. But again, that's all we're looking at here: defense against a force. That's what it is—it's a force being driven against you at all times.

Gotcha. I guess my follow-up to that is like, let's say if in terms of the flattered turning with the left going forward versus the oblique going over to the side, how would maybe my early interventions? What can you do without it?

Well, context makes everything easy because we can say in this representation, we have this, and then we can actually give a demonstration of the rules. So just gotcha.

So I guess a really common presentation I think of a couple of people out in the clinic right now, where they all have like that bilateral posterior compression, and then they have a little bit of like that right oblique curve right there. So at least my interpretation of the moment is to go bottom up to make sure they can get enough hip flexion.

Yeah, nothing really. So I mean, again, these are the people that if they're super on the table and you take one of their lower extremities and you try to move it, it's like right away you feel that resistance just kicking in against you. And you're going like, uh-oh, okay. We've got a lot of times you have somebody that's sort of like this end game representation where all the posterior lower is concentrically oriented. And if you don't manage that first, you don't have a whole lot of space to work with. Gotcha.

Yeah. And then how, so let's say once that's, let's say we have someone that doesn't have that severe of that posterior compressive strategy, but they're more of that kind of oblique turn to that, to that right side. I guess I kind of struggle with picturing how we're changing the forces to create the helical angle back without just pushing further back towards the left side.

Well, you might. See, that's the thing. This is why we're talking about, when we talk about extremes versus a progressive degree of difference. The general rule is I have to move you back on the same axis that pushed you there. So if the axis is here, then I have to bring you back on that axis. If the axis is here, I have to bring you back on that axis, right? Because it's the entire pelvis that's orienting in that direction. So if I try, okay, so here's what's going to happen, okay? So if I'm going to right oblique, and I try to push you back on this side, what's going to happen? If I try to push you straight back on the left, what's going to happen?

The whole thing would just orient over the best.

So here's one of these things. I got here with relative movement.

Right. Yeah. Cause the whole thing did it.

I got here with relative speed.

Gotcha.

Right. Okay. So, what I need to do then is move you back on the same axis that they got here. So I need to do that. Okay. Right. Which is why right foot lead kind of activities on those oblique people is I'm going to push you back into the left.

And so what I feel like for the most part of the effort to make this just happen would be pressure from your right side pushing you back. I hope so. I don't know how else you're going to do it. Yeah, I guess you have to create that compression on the front to get that expansion on the backside.

Yeah, I have exactly right. Exactly right. I have to push back into the left. Again, like I said, this is typically going to be like your, if you're in a staggered stance, it's a right foot lead. If you're in a split stance, it's a right foot lead.

And then, how are we doing on time? We've got four minutes. So then I've kind of been doing almost a cookie cutter thing. Because I kept thinking in my head, it was like a posterior compressive strategy on that left side that was pushing up and over. And I'm ready to clear that up on a coaches and coffee call. And Alex, I remember, had asked that question. But then I guess, then the other thing would have to really be looking at the person's foot to make sure like what part of the gate cycle they're kind of biased towards to get them out of it to really see that change or could you at first?
