If I have sufficient compression and expansion, I will always have a gradient that will keep me within a certain range. So you said homeostasis. So let's use that as a representation. Okay. If we were looking at blood pressure, what would be average, average, not normal, but average blood pressure?

Okay. Make it mechanical. You know you've got a neurologic insult.

It's an ear and foot. He gets enough weight over the foot to push it down. But again, he's doing it. He might even be using his neck to drive this. It's way up.

No.

Perfect. So which way is dorsal rostral facing?

Okay. Um, so would you say that, because the posterior side is like a parachute basically on an era? Yeah.

Yeah. It's down force. We have to put pressure down somewhere. That's what you're trying to do.

Does that make sense?

Obviously she's not based on her jump, but you have connective tissue behaviors that are also in play here. Given enough time, a deadlift is really slow compared to the counter movement and a counter movement jump. So you may have a situation where she can't go from the yield, which is the energy storing position to the energy releasing position.

There are no generals. There's no general. Everything has a specific effect. We might not know what it is. And it might be affecting a number of things, but each one of those things is responding very specifically. There is no general. There are broad, so we can encompass a number of things. But general doesn't really make much sense. Again, all these vague representations are not helpful to anyone. And then they wonder why people are confused. And just because something's been around and the jargon-laden stuff that just gets perpetuated, because nobody's challenging it, they're not using reasoning skills to go, wait a minute, what does that even mean? It's not helpful. But do you see what I'm saying though? It's like all of those activities have a utility. What you need is a better representative model so you can say, oh, under this circumstance, this would be a useful choice, or maybe a better choice under certain circumstances.

So how do you know how far in one direction you would? Let's just say side to side. What would be your distinguishing characteristic to tell you that you're really pushed over to one side?

Cause they're not rolling that way yet. So we can't turn that way. Right? I'm creating the potential. So I'm creating the relative position of the pelvis where I can capture relative motions. Gotcha. Okay. You follow?

Yeah, so now I'm gonna get this hard twist into ER here, right? As I go forward, I'm gonna get farther and farther forward. This is gonna ER, ER, ER more. This will twist in opposition as far as it can until it can't. Okay, so I got ER here, IR here, until I get far enough forward where I can no longer twist the femur. And so the whole femur has to follow me into ER. And now I'm way forward. Do you see the difference in the center of gravity?

It may not yield. I mean, you're putting tension on it, right? So you will have a sensory input, but you don't always get it. Sometimes you have to hold it there for a really long time and maybe you'll get it, right? So you have stress relaxation in the connective tissues.

I'm listening, absorbing. I'm going to go back to Luke's question from the very beginning.

OK. So then you're way ahead of the game. So if you know what the limitation is based on where somebody has concentric muscle activity, and then all you have to do is apply it to any dynamic movement and you would expect it to either create the limitation or it would allow movement to occur, right? So if somebody is squatting, and you see some deviation from what you have in your head as what would be a passable squat, then you can ask yourself, it's like, well, why would they do that? Right? And so if you have somebody that, all you say to them on this online assessment, you say, I wanna see you squat and see how deep you can go with your feet flat on the floor. And so here's what they do. They spread their feet apart really, really wide. They point their toes out and then they squat down and they get to about parallel. What's that representation mean to you?

Correct. I mean, if that's the representation, if that's the key performance indicator that we're going to monitor, so we're going to say, I need to maximize the external rotation, then anything that you do that's bilateral symmetrical has the lesser opportunity to create external rotation because it's going to be compressive on both sides. And so when I work on split orientations, so staggered stances, split orientations, that actually allows rotation to occur. Bilateral symmetrical exercises by design stop rotation. So they are for max propulsion. So when we go back to our propulsive phases, those exercises are designed to increase the force output at max propulsion. The other exercises that we do are to maintain the external rotation field that allows us to turn because that's why you do split stance activities in the first place is because they actually allow turning to take place. So all your chops and your lifts, your half kneeling and all those exercises that you do with the split orientation are designed to preserve external rotation.

What did you just do?

It definitely did.

Yeah.

Thank you. Yeah. Because you feel so stuck post-op sometimes and it's almost like when you're with a patient, it's overwhelming and especially when they're emotional. She'll get so emotional and frustrated with where she's at that I'm trying to do a lot of gentle things.

Let's first move down and forward on the left.

I actually have two different representations. The first one's kind of quick. I just thought it was interesting. So both are female basketball players. One of them's just been getting some bilateral kind of patella tendinopathy symptoms, which are pretty common. But talking to the athletic trainer, he said that she was diagnosed previously with patella alta. Like the patella is riding up higher than normal. I thought that was kind of interesting. The way I interpret that, and kind of based on how she presents too, is kind of concentric orientation of the VL and RECFAM pulling everything out into ER.

What do you mean like doing my job?

So what do you do with someone that can't? Because you remember my.

I'm trying to reach out to them, not trying to move forward.

So is that?

I'll make sure to let him know that.

Cool with that? Absolutely. Thanks so much. Did you have another question, Robbie? I did. Okay. My bad. No worries. You're good. So I think he said in the earlier video, when we're talking about the pelvis and this whole like shape change stuff is super new to me, but because before I used to just want to try to get their pelvis as a unit to rotate in the back swing and that didn't work out well. So it's been much more successful sort of encouraging the shape change, but you said that the left side of the pelvis moves more forward than the right side in his back swing. Is that correct?

All right. That's all in the setup, right? Yeah. Good morning. Happy Friday. I have neuro coffee in hand and it is perfect. Today is the unlearning day of the intensive. So this is the day of pain and anguish and struggle that everybody enjoys so much. We're really looking forward to that. We have a lot to do before that happens. A quick housekeeping item: The applications for the intensive 19 are probably closing today. I think I'm one or two applications away from our target number. So if you're going to fill out those applications and send them in, please do so quickly. I think we're going to decide on that by August 4th, and we'll let you know whether you've made it in. Remember, there's only eight people that can get in. We have to keep it tight and intensive. Digging in today's Q&A is with Peter. Peter asked a great foundational question. Essentially, we're going to break down the squat from a late, middle, and early representation and look at how the center of gravity actually moves during each phase. This is a great foundational question for people who are still a little confused about how the late and early representations shift the center of gravity as we move through space. Peter, great question. Thank you so much for asking it. The podcast will be up on Sunday, probably a little late because we have the intensive on Sunday morning, but it will be up sometime Sunday afternoon. Everybody have an outstanding weekend and I'll see you next week.
