This sucker is actually very durable and very, very strong under most circumstances until you take away its nutrition and then it starts to break down. And so over time then what we have is a situation where you have about a weakening of this posterior aspect of the disc. And so what I'm going to offer you Zach is that this whole situation starts with the disc becoming yielding strategy that we would normally use in early propulsion. So let me give you an example of how this looks in the thorax. So if I take a cross section of a thorax and I'm going to create a turn or I'm going to create a delay. So what you're looking at is you look at the small arrows on the posterior aspect of this thorax and that would represent a concept or yielding strategy that we use in the posterior aspect of the thorax is about taking a step forward or making a turn. So the yield creates a delay to allow the other side of the body to get ahead as if I was taking a step forward. Now if we look at what a disc protrusion looks like you will see this scary kind of similarity as to how this process is going to be initiated. And so all I have to do is have reduction in the resiliency of this posterior disc. And now I can create a greater degree of expansion on one side or the other. And so again, the disc becomes this fractal representation of a larger representation in the thorax or in the pelvis. And so because early propulsion requires that I have a yielding strategy on that side, what if I can't yield? And so under the circumstances of say an anterior orientation of the pelvis, I'm actually going to get a reduction in the yielding strategy. So what this would look like, Zach, is if I anteriorly orient the pelvis, I can't create this yield. So the yield is where I'm going to see this counter-neutation and an ER in this posterior aspect of the pelvis. So this is my delay strategy as this foot lands on the ground. So if I was looking at a foot, let me grab my foot here. What I have to have in this early propulsive strategy is a foot that looks like that. And so again, this is a delay strategy. So this is my early propulsive strategy, which creates the delay that allows the other side of the body to get ahead. And so, again, if I have an anterior orientation, that produces this posterior compressive strategy in the vertebral body. It's gonna reduce the blood flow to the disc or the diffusion to the disc, and then I get my breakdown. So now I start with my bulge, my protrusion, my herniation, my extrusion, or my sequestration, depending on the degree that this process is allowed to evolve.

And again, I would just think it would be the triceps, but you know, like you said, it could be internal rotation.

Okay. What do they have to do several times an hour? If they're wheelchair bound, they have to do certain things. Otherwise, they get a problem down there, right?

And so always working, always trying to evolve, but understand that you need to be patient and let some of this evolution take place. So hopefully that gives you a little bit of a framework as to how I see this whole model perspective. I try to recognize my limitations knowing full well that I am the greatest limitation on the evolution of how I model this complexity within the realm that I work or the world in general.

That muscle can be in constant orientation versus a muscle being in eccentric orientation prior. Are those going to adjust like how that blood flow gets to those areas?

Yeah, so Joey Burton is the skills coach for NBA professionals, Euro league players, college, high school. Basically, if you want to get better basketball in this area, you can see Joey. And so just that relationship, you know, people could say, well, if it's just dollars, right, they can spend money with Joey or they can spend money with me, or they could spend money with both of us and we could have this amazing product that you put out there, right? And so I think too often people get caught up in this like zero sum game. Somebody wins, somebody loses, right? And that's not how it works in most cases. It's about help.

Always make time for you, man. Thanks, man. All right.

Good morning. I was hoping you could offer some strategy input on something I'm struggling with, which is a bit of an end-game representation, where someone gets really strong like DR compression, and then the enlarging ERing of the lower thorax is someone just fighting to get ER. I think it happens mostly in wides where they get really, really wide, really, really big. So I assume that's when they're fighting to get a breath in. I have a hard time with them. Well, first, I assume the progression I'm trying to go in is getting that area to IR a little bit. Lying on the side would be beneficial. The issue I have there is sometimes the scapula gets so pinned that I have a hard time getting my fingers under the edge. And then as soon as they lie on the side, it goes, 'yep.' That's kind of the problem I'm running into. So I was wondering if you had any thoughts or inputs to assist me with this.

It would be hard pressed to get the leg into that position in IR. It's moving midline.

Yes, is that an early foot?

No, not in this case, because again, with the, like the toes are the giveaway, because again, you're looking at the concentric overcoming representation. So again, it's an attempt to maintain stiffness in the tissues and letting the load create the deformation to create the yielding action.

We're slowing down.

Yeah. Like I said, this is the hard part. It'd be really nice to be able to write the annual program and then have it follow it specifically and work perfectly every time. All right. All right.

Awesome. Can you see that I would be supporting it in a position where the muscles would not have to produce tension to hold that position? If I push back under any circumstance, what will happen to the airway? If you feel the head. No, like you said, you said push it back so it's normal, right? I don't want to do that, do I? What happens to the hyoid when I do that? It constricts and contracts. Well, it flattens and it moves up, right? So I'd be compressing the airway and to your posterior. Is that what I want to do? No. I want the hyoid in a lower position. I want the airway open. If I have a lot of anti-orientation at the thorax and my head goes back to the table, I'm bending the airway backwards and making a smaller space. If I lift my head up away from the table, the airway is going to open and I'm going to support them in a position where the muscles are approximated but don't have to produce tension.

Knee orientation that it cannot even do 90 degrees.

Obsidian.

Oh man. Was I alive then?

So box landings, right?

The best compensators are the best, right? But again, get some old video, just prior to where he got hurt, and look at his position at release. That will give you an idea of some of the limitations you're seeing. For example, if you see a head whip—lefties are notorious for a head whip—that means he lacks dorsal rostral expansion when moving toward layback. He's already compressed forward, so he has to throw his head to the right as he releases the ball due to excessive dorsal rostral compression. Do you have someone doing manual therapy on him?

Okay, so you have to look at this in two ways. All right. So think about, there are two ways to slow somebody down. So internal rotation (IR) in general is slower than external rotation (ER). The highest velocity will be demonstrated in external rotation. If I just prolong the IR, then I have extended the duration of the slowest phase, which has to take away time from something else. Okay, there's a fixed amount of time, right? So from one end of the cone to the other end of the other cone is the entire time. If I extend the IR in the middle, I have to take away time that I use to demonstrate the ER. So I don't have enough time to reach peak velocity. Okay, so the duration matters. Force application, remember the seven components of force, right? So how long? Okay, all right. The other one, if I bias you too much towards the IR, if I stiffen the connective tissues, the breadth of the cone then is lost. So you've taken away the breadth. Okay, so there's a skinny end of the cone and a fat end of the cone. 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.

I don't know that anybody would have that perspective directly, Matt. 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 eye-fast 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, cause we had a lot of time on our hands when we first opened, you know, cause 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 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.

The rear foot goes into IR and stays in IR. If you scooted across that really, really fast, there would be no shape change, right? There's no time to deform it. If I have a rear foot that's in ER and I have a bunion where I are bunion. So they scooted all the way across the foot. They went from back to front really, really fast. And then they hit the forefoot and they slow down.

Gotcha.

No. Okay. So down and back and then, okay. So why sort of exists?

I'm struggling with saws. Yeah.

Yeah. Or you, or you do a drop that she has to decelerate that, you know, like, like literally she's in a high box position. You hold the ball up above her. She has to catch it and slow it down. yield into the box, right?

Is there a bend in the sternum? So again, is there a place to bend in the sternum?

Because you're, I'm going to give you partial credit for putting it under the right side. You can be one step better.

We're thinking in comparison between the two.

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