Because he's wide, do I start him in... early and extended angles and then move him into IR.

With the ladder drill, the heel to toe contact occurs later because you'll pick up more from the first metatarsal head.

That might be a useful strategy because then you're seeing where they have to apply the greatest amount of force and then that might be where you want to train them to not have to use the orientation so they can manage the pressures. All right, that would be associated with the force.

So the gradient of gravity would be denser. Like if you were laying flat and your feet were closer to the black hole, your feet would get elongated first. It's like watching Wiley Coyote on Bugs Bunny Roadrunner when they chop off the cliff and his body goes down, his neck gets really long, but his head stays and then it snaps down. They'd be like that.

He didn't give way in the left posterior pelvis under any circumstance here. It's still pushing forward harder than it is on the right. The spine above it is twisting. That's what makes it look like the left, like people say the pelvis is facing the left now. Well, technically speaking, it is facing the left because the spine twisted in that direction. This is still right turn. It's still a right turn in the pelvis. Like the orientation of the pelvis is to keep facing the right. That's the problem. He's running into this because the pelvis still wants to go right. The spine is trying to twist to the left so he can stay straight ahead.

Yeah.

Okay.

Yeah, because she's not capturing all the medial stuff. Now she can still push down into the ground, so this is the thing you have to be careful of. This is stuff we talk about all the time. It's like, remember, IR is going down. It's downforce. So if she can't capture a true medial representation of the extremity, she will still push into the ground. She's going to orient her pelvis forward. She's going to take an ERD foot and jam it into the ground, but the tibia is not going to follow. So she's still in this late representation of tibial ER trying to push down into the ground. That's bad news, right? She never captured the IR position. So that's what I would be working on with her. Yeah, so you capture, you get the early tibial IR first and then you teach her to hold on to her ground contacts and push up into medial so she can push down into the ground.

Yeah, I have done that.

And so what our measures then reflect is they tell us what shape you are. They tell you the physical shape. So I know where you are in the propulsive cycle.

You're welcome.

So the apex is the most relatively IR part of it. So in terms of like some concentric muscle activity, like so I'm asking this question is I'm thinking like you see someone with back pain and walk-ins and they have like crazy twisted dyslotymia and just like an easy way to access like an eccentric orientation to just make them feel better. Yeah, we're in that situation where I'd be going, like if I want to do some just general manual like to be closer to the apex.

And so that's a short arc role. You're just driving it. So you're fixing the humerus against your chest as you're doing globalization. You move the scapula into the position that allows the dorsal rostral to expand posteriorly where you have taken the scapula away from that space. And so then the side closest to the table would be a later representation. The side that you're manipulating is going to be the delayed side.

So that, in that situation, you're like, burritoing it.

Yes, so there'd be expansion in the opposing direction. Therefore, compression would increase where you brought your hands closer together. This is a two-dimensional representation of a four-dimensional problem.

No.

Well, it depends on what you're doing. Do you know the fastest way to improve your top speed sprinting? Sprint. Do you know the fastest way to improve your vertical jump? Jump. It's specific. It's 100% specific to what you're doing. High jumpers do thousands and thousands and thousands of jumps. And if you've ever looked at like their Achilles tendon on their jumping leg, it's ridiculous how adaptive that sucker is. They get this big honk and thick Achilles tendon on one side just from doing a bunch of jumps, like thousands of jumps over a period of years, right? And so they optimize the stiffness and the ability to store and release energy in the longer tendons that store the most. That's a pure adaptation from the activity itself. It's always the fastest way. If you want to increase throwing speed, throw. If you want to jump higher, jump. Now, there is supplementary training that you can do to enhance those things to whatever degree you are adaptable, but that's typically the fastest way to do it.

Well, walking up the stairs, right?

Okay.

I love that. OK. So gravity works. Right. So I land and there's this force that's coming up into the leg, right? I'm in this ER representation approximately, but I'm starting to put force into the ground, which means I have to have a turn inward, right? The connective tissues are starting to absorb energy. And so that's like compressing a spring, isn't it? And so if you look at the, the twisty stuff in the femur, I got this perfect little spring mechanism going on Donna. OK, so that distal femur is going to start to absorb the internal rotation before the proximal femur does, doesn't it? You see it? OK, cool. OK, where are we going next?

Ian, you're doing Frieberg's laws, right? It's side bending and rotation to the same side in the cervical spine. Is that right? Yes, sir. Okay. I thought so. Yeah. They're not the same shape though. The facets are not the same shape. So if you look at C3-4 and you compare that to C6-7, the facets are not the same shape. In fact, the concave to convex nature of those facets is actually different, which is why the lower cervical spine has to ER to create a rotation in that direction. And then the upper cervical spine is actually gonna look a little bit different. It's gonna be more of like that's what you're calling a side bend. It's not a side bend. It's all rotation, but understand that the rotations are created a little bit differently.

Yeah.

So what that does is it starts to twist the femur into internal rotation, which pushes internal rotation into the pelvis. So what I did is I put you in an external rotation space and I started to superimpose internal rotation on top of it.

And then where do I need her to go though?

He shifts to the left first.

In that situation.

Yeah.

Yes, yes, yes. You do have other elements of this, such as the width of the Achilles, the amount of tension on the Achilles. You can see the asymmetry in somebody that would be more ERD on one side, where the center of gravity is further forward and there's less weight on the calcaneus on that side and you'll see the increased tension through the Achilles which will give the appearance of a narrow wing, right, because as you pull the Achilles long it will narrow and therefore its attachment on the calcaneus will narrow as well. So that's also in play. And so if you had somebody that is maybe not as far forward, they've got a little bit more of the anterior orientation of the entire foot where the arch is really, really low, but they're not fully loading the forefoot like some people do. You'll see a wider representation as well. So there's a lot of stuff that can give you a visual representation of that. The position of the fat pad plays into this as well. You get somebody that is very, very ERD, not a lot of weight on the heel, the fat pad's not going to spread out nearly as much. And so you've got a lot of stuff going on there that can give you the appearance. The cool thing about the calcaneus is that you can grab it and you can compress the soft tissue around it. And so you can actually feel some of the turn, especially when you get somebody that's got the really hard ER twist. The foot's so ERD they've got a lot of concentric muscle activity in the bottom of the foot, so the arch is very, very high. You can feel the turn when you grab the calcaneus. So there's nothing wrong with doing that back in the olden days when we used to draw lines on the calcaneus and then try to draw a line on the midline of the calf.

I guess early.

Okay? All right. No, again, I just want you to see where these representations take place. Okay? So if I have the capacity to move the hip through the excursion of what would be traditional flexion, the pelvis has to be able to change its shape. It has to be able to access an ER position and the IR position for me to have that full excursion. It's not just the hip joint like pivoting in the acetabulum. It's like, if you don't get the shape change that's associated approximately, you don't have that range of motion. It stops. Like literally it stops moving. And so again, that's, I think that's the question that you're asking. It's like, it's like to throw out a number at you. I don't know how valuable it would be. But you, what you would do is again, this is where the averages are actually useful. It's like, I can make a comparison, but then I have to understand it's like, where am I measuring this? Right? So if you measure hip internal rotation with the hip bent 90 degrees.
