Like we've got a definition of like we use a pronated foot, right? We've got a definition of that. But what's happened is that every foot that has a low arch has been branded as a pronated foot, which implies that if I call every foot that has a low arch pronated, that it's using the same strategy, which it's not.

I would do everything that I could to promote the appropriate shape changes, the muscle activity that would reduce that position and then tell them to go to sleep. Do you know how hard it is to follow instructions when you're asleep?

That's a sign for me that, yes.

But everything that starts out electronic always becomes analog.

Yes.

You jump off a box you land on the ground and you stick it in.

Okay, you need to get some, because what it sounds like, it sounds like you just got a ton of concentric muscle orientation. Soft tissue is gonna help calm that down. So if you don't have anybody to work on them, you're gonna have to roll them around. You're gonna have to use the ground, all of your little soft tissue-y tools and stuff like that to calm some of that muscle activity down, right? You gotta create a gradient for space. You don't have any space. Right. Okay? Got it. If you could probably use like a split squat comparison for like a before and after on lower, right? To make sure you're getting foot contacts, knee position, hip position, pelvis orientation, okay?

Okay, make the cone skinnier just in general. So from the skinny end to the fat end, it doesn't get as fat. Okay. That's the re-expansion. That's the re-expansion of the connective tissue behavior. So I can't deform it. I can't deform it. There's not enough differential between the compressed representation and the expanded representation to reach peak velocity. So they're two stiff. So one is too much time and one is too stiff. You see the difference in the two.

Now, we've messed around with that kind of stuff. Okay. Here's what I used to do back in the olden days before you were born. Actually, this is like a very early 1.0 kind of an experiment. So you remember back in the olden days when I did like 77 tests in my assessment? You've heard me tell that story? Yes. Yeah. So what we used to do, because we had a lot of time on our hands when we first opened, you know, because you got like, you know, eight people coming in and so you got a lot of time. We used to do the assessment and then I would run them through a dynamic warmup. So they got tired and then I would remeasure. Okay. And you, you would definitely see the deficits start to show up. And it would be different depending like certain types of athletes like our soccer players were much better conditioned than most folks that would come in. And so they wouldn't change much. They would have limitations that were associated with their typical training and their typical sport. But the people that were not regular athletes nor well conditioned, the deficits would show up. And so you could see that because I did a talk. It's probably still available on DVD actually in 2008. And I brought up this concept of fatigue because this stuff is in the research. The way it shows up in the research is they talk about instability. Right. And again, you can look it up. All you got to do is look at ankle instability, core instability. I'll talk about that a little bit too. What is that? The cool one? Honestly, Matt, I've never seen it well-defined, so I don't use that term. Hip, you'll see hip, and they'll talk about spine directly a lot of times. But what they'll do is they'll, they do make comparisons, like they'll do like single leg landings or something like that, and they'll do it in a rested and fatigued state, and they'll show the differences. And the reason that the differences show up is because you've altered the capacity for strategies, right? You've limited the strategies that were available. And so the equivalent perturbation throws you off your center, right? Too much greater degree. So it takes longer for you to come back to a controlled position or you can't recapture it. So it's all there, like I said, but I don't think that anybody would look at it from the exact same perspective that we talk about. But still like, it's a, it's apparent. I don't think it's a, I don't think it's a mystery, but again, it wouldn't be perceived the same way.

And then that's where the iterative changes would be seen upwards. Yes, sir. Yeah.

Okay. That would have made the assessment much more easy.

Yeah.

Yep.

So it's the arm movement.

So between the manubrium and the sternum, there's a little synchondrosis, right? We call that the angle of Lewis. One of these days, I'm going to get an arcade or a synchondrosis named after me. We'll try to figure that one out. Because whoever Lewis was, I don't know. How does he get that? Anyway, the point is, when you think about the compensatory strategies that are associated with the compression, I don't know if you remember the slide. You've seen this slide because I showed it when you were in the purple room, where you see the delineation of segments where the compressive strategies are layered on. So we have DR and we have upper DR, right? We have sternum and then we have manubrium compression. And so there's a line that delineates the manubrium from the sternum that goes straight through the thorax and it kind of hits about T4. What a coincidence. And then from a structural reductionist perspective, they have to call things things. So they go, oh, you have T4 syndrome, which I don't know what that means. You'll have a sequence of events that would be associated with that area that would potentially restrict motion. So you mentioned that the guy's got limited neck motion. He's had a compressive injury in the cervical spine. He's getting symptoms similar to what would be associated with the diagnosis of thoracic outlet. So what do you think he's getting compressed?

Okay. Is that where the wide ISA came from when they went forward on the run? Let me ask you this. I'm hopefully going to make this a little simpler. If they go back on the right, time. Forget I said anything. Here we go. Wide ISA archetype, full relative motions. They start to make their first move, which is the movement on the oblique axis. Left side goes up. They're now on the oblique axis. What is the orientation of the sacrum?

Am I in the purple room?

I got a lot of ER that's going on right there. That posterior lateral elbow. You see it.

I was just making sure that it's one of the things that you have to recognize over time. That you just never knew what the options were. So if I talk about ERs and IRs, okay, to most people, they're gonna see turns. They're gonna see ER turns out, IR turns in. And I would say that ER goes up, IR goes down. Oh, I didn't know that was an option. Yes it is. But that changes the perspective a little bit now. When you start to look at somebody and you say, 'Oh, this is turned out. This is turned in.' It's like, wait a minute. If I have a compressive force, guess what? That's the superimposition of internal rotation. Right? And so you have to account for that. But see, if you never knew that that was part of the option that's going to take place during an internal rotation and an external rotation.

At the knee for pelvis.

Potentially. Depends on where you are. Think about this. If I'm doing an OBERS test and they don't have any internal rotation, it's because the fluid content is medial to where I'm measuring or posterior, depending on the limitation of the test. So let me use a traditional hip extension. Okay. Why doesn't the leg come back? And people say, well, you've got muscle activity on the front side. Yes. But it's the fluid pressure moving posteriorly. It's the fluid volume rather, moving posteriorly that creates the interference to the movement. It's not the muscles. Muscles are just keeping it in a certain space. It's like when you lift weights and stuff, you're stacking weights on a column of compressed water.

I'm not sure I understand.

So as you move through the excursion of the split squat, you move from an ER bias at the top of the split squat to an IR bias at the bottom of the split squat. That requires a shape change. So the pelvis has to change its shape and the muscles have to change their orientation as you move through space. Otherwise the joints don't change position. And then all you feel is tension associated with the connective tissue.

Okay.

Yep.

Absorbing.

Okay. Where would you capture the greatest degree of relative motion in an early representation, a middle representation, or a late representation?

Okay, now I understand what ground contact you are trying to use to create the change.

So just to be clear on this, when I'm getting that distilled proximal from that early representation and then reinforcing, although it's a fake med ball, so I am going into internal rotation, but it's still a distilled proximal force coming back on the fake throw, isn't it?

Somebody else was going to say something.
