She is weight bearing.

My point is that you're looking at somebody that probably has the upper levels that are getting the compressive strategy superimposed. So you've got somebody that's getting a compressed manubrium and a compressed upper DR, because that would affect neck range of motion. That's going to affect the nerve's ability to slide through tissue. So any number of symptoms that would be associated with that are probably associated with the fact that they've got the uppermost aspect of the actual skeletal system compressed.

Let me ask you this. I'm hopefully going to make this a little simpler. If they go back on the right, okay. 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?

Yeah.

And you have medial triceps. So you think about the, so now take all that musculature and put it on a knee and then look at the position of the knee under that circumstance.

Well, again, it's like, what is your exposure? How do you relate what your findings are to whatever thought process is in your head? It's like looking at a straight leg raising and going, 'Oh, you have tight hamstrings.' You're blaming that because that's the classic representation. And that's what they'll teach you in physical therapy school. They're going to blame a structure. And then you get stuff like, 'I'm just going to static stretch a structure and that should help.' And then it doesn't help, and then you wonder what's going on.

Okay.

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. 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.

Okay.

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. 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 all you feel is tension associated with the connective tissue.

That's interesting. Matt. So here you go, boss. Here you go. You're standing on the ground. You look down between your feet and there's a green dot on the floor. So your feet make a square. You understand? Okay. That green dot is your center of gravity. Right. And so every time you take a step, that green dot is going to have to move with you. And then where you place the load is going to control how far and how fast that dot moves into different directions. So under normal circumstances, your center of gravity moves like an S curve on the ground. Like if you were to shoot a beam of light straight down at the ground, right? Okay. And you're walking around the ground, it forms an S curve. But if you put a load in there, that S curve is going to start to change shape. Okay, so you're going to get a delay on the left side and you're going to get a lot of almost a horizontal representation of IR. So it's going to sort of create a limping S curve. But that's what you want under the circumstance because you're trying to promote a certain shape. You're trying to promote a certain muscular behavior. You follow? Yeah, yeah. The way that green dot moves tells you the response to the position and to the load. Yeah. But this is also why you have to get the magnitude of load correct because too much weight and you're going to stick yourself way over on one side and you're never going to capture the element that you want. So if I give you a strongman style suitcase carry, right? They're not concerned about capturing ERs and IRs. They're concerned about the most load that they can carry, right? Okay. But put it in one hand for them. And you see the kind of lean over, and then they'll even throw the other arm up this way, right? As a counterbalance and all that kind of stuff. You understand what I'm saying? It's like the load is literally dragging along the outside of their leg because it's so heavy and they can't. So that's somebody that can't shift their center of gravity away. You just created a massive downforce into that leg and then you picked up almost the other foot, like the right foot when it's on the ground is very, very light on the ground, the left foot becomes super, super heavy on the ground. That's the exact opposite of what we're talking about because the magnitude of load took them outside of their base of support. And so they have to create a counter position that gives them enough counterweight to offset that load. You see it?

Okay, so hang on a second, boss. If I lay you on your back, where are your guts? They're posterior. They're laying on your back, right? They're actually promoting the potential for a delay strategy into the table, aren't they? Awesome. If I stand you up, where do they go? Down and forward.

Yield.

OK. That is correct. Because, again, that's that. But now we say why. Why is that the better place? OK. How do I typically describe it? As in regards to ERs and IRs, do you know?

OK, so if the ischium is, let me back up. If somebody's standing up and you see their rear foot is everted, you might need to put it under the ischium to put pressure on the lateral aspect of the ischium to move them towards internal rotation. OK. If you're trying to drive an early internal rotation from the femur to the pelvis, then it needs to be under the trochanter. Do you see the difference?

Yeah.

Yeah.

So you have two starting conditions that are absolutely different. There is only one of them that would turn on a more vertical axis, which we would call a flat turn. A wide ISA does not turn on a flat turn. It turns on an oblique axis by design. The flat turn would be exclusive to the narrow ISA representation because the helical axis is more vertical. They turn on a much flatter representation.

I think my road there might have been a little bit long, but I guess once you realize it helps.

Okay, real simple. So right now you can feel your heel, you can feel your first and your fifth metatarsal head, and you can feel your toes on the floor, correct? Okay, cool. All I want you to do is raise your heel off the floor. Now you feel first and fifth metatarsal heads, and then you feel your toes.

Yeah.

Okay. So I just, I guess it got me thinking about whether that strategy was correct to go along with another strategy that I wanted to employ, but I wanted to see if I was going the right direction.

Good morning. Happy Thursday. I have neuro coffee in hand and it is perfect. And that is really good too.

Yeah. It's a very shallow, quantitative appreciation.

Yeah. No, just help her with the Luca tape.

Who's the better bench presser?

I don't know if that was clear, but this is a big deal in regards to when you're training athletes and this is why they have to play their sport to prepare for their sport. That is because the sport is a very specific environment, and through the contextual elements, the affordances that are in the environment allow us to make determinations and make predictions specifically. That's why nothing in the gym is as specific as the sport in and of itself. Because everything that I do in the gym has a higher degree of predictability under most circumstances.

It's too easy. Yeah, medial heel and ball of big toe. Okay, what else? I'd say the left posterior sacrum.

Right.

Yeah, I imagine.
