Yeah, I know.

And so the left side has to, for me to have a delay on the downside, the left side still has to stay ahead of the right as I'm rolling back into that position.

OK, so what would happen?

Probably not because he can't.

inhaled position.

Did you see me? Look at me. So her spaces are here, right? They're not in front of her.

So connective tissues are rate producers, right? By their stiffness or their yielding capabilities, right? So the overcoming is a stiffer representation and the yielding is the giving way, the storage of energy. Okay.

Yes, yes, yes.

Yeah, yeah, yeah. So it just depends on the intent of the activity. If you're just driving yield, you would just stop there and allow for that yield to kind of, that time.

I've seen that in some beginners. Their head looks like they're a chicken or something. I mean, they're really through.

Hey guys, welcome back to the QB Docs Podcast. Dusty is here with me. This is Doc Drew, but Bill, we'd love to pick your brain on your model. We'll start with your model here first. And we've been diving into this thing the last few months and there's a wide ISA and a narrow ISA and some things that happen off of either even a wider narrow, but I think one thing that we're really getting caught up on is how compressed is compressed, right? Like from a continuum of compression, because we see compression at different areas of the body. And based on what I say you are, you're going to present a little bit differently. What does that continuum look like? What are some of your key performance indicators that are telling you how compressed someone actually is?

Everybody references him now, right? It's a requirement. If you use the word model, you have to use the quote from George Box.

Okay. You see it? Okay. That'll be one I have to re-listen to, but I'm standing up.

So the femur is going to give you the representation of the bow, right? But she has a bowstring that's going to go straight down from the pelvis toward the foot to keep the IR inside of her base of support, right? She's got to produce it somewhere, okay? So there's going to be muscle activity that's going to create the bowstring. Is there? So let me back up. If she swayed forward a little bit, do you think she has a rectus strategy going on?

Yes.

I would have more external rotation on the left, more internal rotation on the right at the hit.

Okay, so with that right oblique where he's got that left side and he's stroking up as you've indicated there, that's going to be indicative that he's lost external rotation. I'm trying to equate this to the hip orientation. He's preserved his ER initially, but lost it as he's gone further into the repetition, then lost some degree of internal rotation with it, or not really, both.

Right. So I didn't know what the answer was already. That's good. I appreciate it. I figured if you've done this like 17 or 20 times by now,

Fast for a 65 year old retired nurse with crappy feet and a meniscus injury. Okay. Yeah. You understand?

Yeah.

This is an inhaled representation of the scapula. The scapula is going to tilt down, and then you'll get dorsal rostral expansion, which will turn the glenoid. This is an external rotation representation. Now, where's my pelvis? I want to show you how the pelvis does the same thing. So you know that would be external rotation, right? Do the exact same thing with the scapula. As the arm swings backwards, the scapula will do that. You'll get an external rotation representation there, which will create an expansion. Let's make it simple with the left arm swing. As I swing the arms backwards, the scapula will turn relative to the humerus. It will look like the external rotation nomination would be the same representation at the shoulder. It's not turning outward; it's actually turning the other way relative to the humerus.

Well, maybe he can't yet because he can't put force into the ground because he's expanded on the left side. But I can teach him how to put pressure through the ischial tuberosity on that side, which is an internal rotation representation, which is forced down into the ground. I can teach him to capture a foot position and I can actually approximate that foot into the ground as he's doing his little activity. And guess what? I'm teaching him to coordinate pressure into the ground. Wow. Wow. Wow. I can't guarantee that he'll be able to walk, but imagine if he could control himself in a seated position where he can shift his weight around and actually make that side useful, but you're going to have to use the unaffected side to help you do that.

So, in this case, I was biasing you towards that inhaled position. Your pump handle would essentially be up. For the pump handle to go down in that circumstance, your arms would have to move.

Right. Right.

Awesome. Awesome.

The arm does not weigh nearly as much as the leg does, and you measure the arm in a little bit different place under most circumstances unless you're sneaky and you know where to measure, and you know where to measure the ERs and IRs differently, okay? And so it doesn't turn the thorax as much as the pelvis turned when you were making your measurements. So this is one of these dirty little things that the table makes a great constraint, but you got to understand how you're moving on the table when it happens. Because again, when you have all these asymmetrical measures and you see this one measure where both sides look exactly the same, they're not the same. It's like you arrived at those measures differently. So that's why you have to account for in every measure you have to understand what can be contributing to the change.

Yes, yes, yes. So you dampen it, so you dampen it and it just spreads out, right? All that, all the force spreads out through the system and then you teach them to dampen those forces. So if I had somebody that, I don't know, was having trouble with like a decelerator kind of an activity, right? And I want to teach them to yield and absorb that more effectively. That would be one of those strategies that you could use. I'm just going to pull you into your cut and then hold it and stick just like if you're landing a jump and stick kind of a situation.

So let's go back to Kyle's question. We can actually use the press as a diagnostic, right? We have a comparator now. Let's say that Manuel is working with somebody on their overhead press and he sees this gigantic anterior translation of the cervical spine in the head as this person is trying to finish the press. That's going to be a rather aggressive position of internal rotation to finish the press. But it might be indicative of the fact that they started from a deficit of dorsal rostral expansion. They don't have full dorsal rostral expansion. Therefore, the IR element would get further exaggerated. So now you have a comparator. So if I want to reduce that, then you say, 'Okay, do your overhead press.' And then you do something that you say, 'This activity is going to improve dorsal rostral expansion.' And then you have them overhead press again. And then you have a comparator. So now Kyle has another test for shoulder mobility or neck, right? Because they work together. And so again, that's just knowing what your table tests are going to show you. What position of the scapulae are you going to be in? How is that going to put pressure against the dorsal rostral thorax? What is the end result of that motion in regards to its bias toward ER and IR? Right? So eventually, we should just be training people, right? Because that's where they're going to be demonstrating these things anyway. Got it. Does that make sense?

Yeah.

Yeah, and I put that up on my board because it was one of my daily sayings. And then somebody came along and put right between model, they put super. Oh. That changes everything.
