Left posterior lower cervical, which would be related to another area, upper dorsal rostrum.

What kind of a foot are you actually looking at?

Okay. Don't change the relationship at all between your hips and your pelvis and just tip over on the left side to your elbow. Stop right there. Put your left leg on the ground. No, no, no. Keep it bent. Just drop it down to the ground. So that's the same ER you just had, right?

So you don't roll over your big toe. Okay, then you have to be on the outside edge of your foot, right?

Yeah, OK. So the difference relates to conservation of momentum. This is the physical principle. If I don't release, I alter the momentum. So when you throw a ball, you project the ball in a direction, and the ball pushes back against you. But because you're bigger, the ball keeps going in that direction because the amount of velocity acquired from the throw must be maintained for conservation of momentum. Momentum is always conserved. So if I throw a medicine ball, the recent medicine ball goes in that direction really fast is because I'm moving in the opposite direction very little, but I am moving in that direction. So it will stop me. So if I do a medicine ball throw into a wall, as I release the ball, I get pushed back to a certain degree. That creates an overcoming connective tissue behavior because it's pushing back against me and I'm resisting. If I fake it, I am prolonging the deceleration of myself, which means that I will elongate the connective tissues to dampen and slow down. Do you see the difference?

It has to, because the space is going to have to close. If the space was open, they wouldn't have to move any farther. They would already be expanded. They would be taking up that space.

If you just got a wall on in two big spaces on either side, you're on one space and then they still have that big open space. So if you can create an isolated area, that might be helpful. That might be helpful.

So this is the difference between force application and the demonstration of velocity in any kind of throw. If we were talking about a javelin, baseball, or anything else people throw, the point is there's a point of maximum force that propagates energy into the implement, and then there's the release. After release, there's no more force application; the force application is reduced. When walking across the ground, at the point of maximum force, your force is maximum when you're in the most loaded position with ground contact. As you push off, the force is much less than at maximum force, and velocity is higher. So force would be reduced, and you would go in the opposite direction, technically speaking.

So she was late on the right side.

No, you're so close though. You're so close. It is a representation of ER, but it's a late representation of ER. So that's the leg action. So again, planar thinking screws the whole show. Because people say the leg is behind you. And so they'll say, well, the hip is extended. It's like, no, it's not. It's actually rotated, which is that ER measure. So abduction as you're walking. As the leg is behind you and your toe is on the ground, your heel is up. That's a late representation of propulsion. That's actually an ER representation. The pelvis had to change shape into ER.

I figured when you, when you said 70s and box squats, I figured, right?

OK. OK. All right. So now, so how can we take similar concepts so we don't have to take them out of sideline? But we know the high obliques it is out because of the elbow position in the high obliques it. It's going to push them right back where they started, which is what I do not want to do. What's the easiest way to change the activity, to give me the capacity to change, Teya, you're gonna say it out loud for me, you're just gonna mimic on the screen there.

There's too much potential for interference in regards to the pelvic orientation. It's like, okay, here you go. The people that would get accused of tight quads, right? They never have heel to butt prone, but they could have heel to butt supine. You see the difference. So I'm looking at the capabilities of the knee itself. I don't want to make a judgment call on muscle orientation as far as the limiting factor. It ends up creating an ineffective representation and people make bad choices as to what needs to be done.

Well, you have to get an axial skeleton that can recapture relative motions. You have to restore the relative motion at the shoulder. You have to identify the hand position so you know what position the elbow is in, so you know which way to twist it. It's not as clean and simple as 'oh, you just do this exercise.' You have to understand what you're trying to recreate. So the simple answer is you have to get your AP expansion so you have relative motions available at the shoulder, but then you have to understand where you came from. If you're oriented into ER, if you have a proximal humeral orientation into ER, you have to IR that first. Otherwise, you don't have access to any elbow position or hand position. You can go after elbows and hands right away with the understanding that you have a shoulder that's probably going to kick them right back out into that same orientation if you're trying to control a symptom. So if somebody comes in with elbow pain and they can't do anything because the elbow is so uncomfortable, we might do something at the elbow that would alleviate a symptom to allow us to do another activity proximal to distal first from a strategy standpoint, because it's a matter of selecting activities that would reduce the concentric orientation that got you into that position in the first place.

Yeah.

OK. So what direction is the right glenoid pointing?

The Olympics are one of the greatest representations of the influence of physical structure. You take the best high jumper and have him stand next to the best shot putter—totally different worlds. Both human, both with the same body parts, but different physical structures. Therefore, the way they apply forces into the ground are going to be different. The outcomes are obviously going to be different, their connective tissue behaviors are going to be different, and so you have to account for this. It's like, 'I've got a high jumper who needs a tremendous amount of internal rotation into the ground over a very short period of time, but he needs to access that internal rotation slightly in front of his center of gravity.' Now take the center of gravity of the shot putter: he's going to use a lot more orientation to apply that force into the ground because he's got a longer period of time to apply that force to the ground. His force needs to be a lot—his peak force is going to be very, very high. You see the differences when you say, 'How do you progress somebody?' You know, with a black and white answer, Bill. Unfortunately, it's rarely that. But it is principle-based. You just have to recognize what the principles are. Again, this is why the generic program concept doesn't work—you apply the same program to two different people, why do you get two different outcomes? Because the starting conditions were different, and therefore the outcomes will be different. That's the thing you have to recognize. So you fall back on basic principles. We can use the two extremes: what kind of an archetype are we looking at? What kind of configuration do they have in the relationships between the thorax and the pelvis in regards to circumference? Because that determines how easily they're able to move their center of gravity upward and downward. It's going to tell you how long they spend on the ground, how big their medio-lateral propulsive representation is. A wide ISA individual has a much broader duration and physical space to apply forces to the ground, whereas a narrow individual does not. That's why when you see tall, slender folks come into the clinic with painful situations, they're trying to apply forces into the ground in an external rotation representation because they spend more time in that space—because their physical structure says, 'Guess what, you're going to spend more time in that space no matter what you do.' And so that becomes the difficulty.

It's just numbness. Yeah. Okay. So if it's just, if it's just here, then you've got a hand to wrist orientation. It doesn't mean you have to clean. You, you have to ignore this. It just means that it might be more local here. Whereas up here, you've got the shape change where the, where the, uh, the nerve comes, comes through the cubital tunnel there, right? So again, you might have two different representations here. You're going to have to clarify the hand position and then the humerus elbow position in both cases. And you may have to do the same thing. I don't know. But the thing I want you to recognize is where do you have the biggest differential might be where you spend more of your time. So this is a bony band. This is a bony band here. This is, this could just be like a relationship of, of hand pronation to the, to the wrist orientation.

Okay. And then you're measuring hip deflection and they've got 75 degrees of hip flexion. Okay. That means they have a very limited space that you can actually access. If you do any exercise outside of that range, you have to assume a compensatory strategy to get there. So I have to select an activity that is in that space. When I take an effective breath, not a compensatory breath, that's going to promote the expansive strategy throughout the axial skeleton and into the extremity based on the contact of the distal aspect of that extremity. Okay, so I'm putting them in a space where they can expand, where they do have relative motion, because they don't have to use a compensation to find ER.

I'm trying to clarify the terminology regarding distributed versus local forces. There's clearly a force magnitude effect—for example, when using the same body weight in a bilateral squat versus a single leg squat, I'm loading roughly double the weight on my single leg. But if we were to equate the loads, how would I describe the difference in overcoming and yielding behaviors between the single leg and double leg squat?

Okay. So like top half is painful, bottom half is not kind of thing?

Why do they stop?

I can help you. I can help you. This is going to be real simple, crazy simple. You ready?

No, that's the depression you're thinking of. This is the sideline version where you're going to bring the scap off the thorax and then as you drive expansion, that's going to help. You're literally manually creating the DR space to allow that to expand under those circumstances. That's a great place to start from a manual perspective. So here's the thing. Have you manipulated yet?

Force is in IR, velocity is in ER. OK, you see it? Yeah. If I tighten the bow string and I push them more towards force, OK, and there's no spring back, they are already yielding. This is the difference between, it's like the people that walk in with the so-called valgus representation, they could be very, very strong. They just tend to be less explosive because they don't demonstrate velocity because it's very difficult for them to move towards ER.

So, do you get adaptations in regards to the collagen content of connective tissues when you load it repeatedly over time?

So if I push there, you see where I'm at? Okay, here's the axis of rotation right there. If I push that in.

There you go. Problem solved. Awesome. What do I have to do to make a varus?

People think they do. They think they're entitled to certain things. They think they deserve certain things and you don't get anything. Trust me. And if you look at it like that, you're going to do really well. But understand it's a habit and it's a process. Like every time, every time money comes into your life, keep it.

Correct. Yeah. So ultimately the goal is to be in the rack position without the hands being open, right? Or without like arching excessively. You don't want to see a bunch of compensations. You want to see somebody that's actually got a useful representation of a rack position. So your strategy, your thought process, is useful. You just have to be really, really careful about how much force you're driving. Because again, you take somebody past a threshold and right away, you're gonna squeeze. They're gonna compromise.
