Your goal is to produce IR. If you're pushing into the ground, walking across the ground, you will produce IR. How then becomes the question mark? Are you going to do it with ER structures? If you're doing it with ER structures, you've got to bend stuff. Right.

So keep going, right? Until the connective tissue no longer has any more yielding capabilities. Take it to the end of the yield, you have to concentrate on muscle and you're at the end of the connective tissue behaviors. The only thing you can do at that point is start squeezing.

Yes. Now you understand the difference of putting somebody's foot up on a box versus just elevating the heel. That would be a great strategy. And that might be like the answer, right? If you put the foot up on a box in a reduced gravity situation, that's essentially what you're doing—taking gravity away from the foot. What does the foot look like? If the foot shape gets better, then you don't have to actually do the mobilization.

Where you want it. The funny spot. Yeah, like somewhere. It's a technical term for those of you that don't understand. It's the funny spot. Yeah, no, but it is. It is. It's absolute. It's absolute. So think about this, Cameron. Here's the rules, right? Yeah. There has to be a place that absorbs the energy. There has to be a place that that that it's released, right? Yeah. The shapes determine what direction everything goes. Right. And so that's, that's always been the goal is like, I got to make sure I get the shapes right so that the energy goes in the right direction. It goes to the right places where I can distribute it, utilize it, and then redirect it.

Because you look at what is preventing, so I need that calcaneus to move into a traditionally everted representation. Right. Relative to the starting conditions. I don't want it to be excessive and that kind of thing. Right. Cause I can create a compensatory strategy. That's kind of what you're doing. I'm sorry. That's what your friend's doing. With that bunion representation is you're creating this orientation. So it looks like you're getting this rear foot eversion when the reality is it's like, you still have a subtalar joint that it's in an ER representation and you would just IR the entire foot up to the first metatarsal. Okay.

Yeah. They look a little different. You have to appreciate the turn that's taking place. So, go back to your hamstring representation. Think about the seated variation of a hamstring exercise and what that would look like. You're creating tibial internal rotation as the knee bends. Do the same thing in the arm.

So there's a relationship there that the tibia is going to move in a very specific direction. But it also means that the fibula has to move in the opposing direction to make sure that I get the right shape so that all the fluid stuff goes in the right direction. So the energy that's going through that fluid goes in the right direction.

That's why you can't use them as the same measure because they don't, right? Yeah.

Even though you've never done it before. I'll do this exercise. People will love it. I'll have no clue. But I'll do that.'

So he's got an ERD orientation at the proximal hip that you took away. So that reduces the need for the anti-orientation. You gave him true IR. Instead of an anti-orientation for IR, you gave him relative motion IR. So he was superimposing, he was now capable of superimposing the IR on the ER, okay? You untwist the knee, right? You reduce the load on the medial aspect of the knee as he is starting to try to load that foot with the crossover into the cut. You gave him legit IRs, when he needed higher force production into the ground versus orientation and downward compression through the bones themselves. So the hip was a compressive strategy that is magnified. The knee was a compressive strategy that was magnified by the forces of the cut. You gave him the capacity to distribute load by restoring relative motions in the knee.

But you wouldn't do that. You wouldn't do that first thing walking into the purple room. You would have to create a gradient first. See, there's your problem. So this is the problem that's associated with a lot of these people that are very, very compressed is that they just don't have a gradient form movement to exist in the first place.

Good morning. Happy Tuesday. I have neuro-coffee in hand and it is perfect. All right. A very busy Tuesday coming up. We're going to dig straight into today's Q&A. This is a question with Ian. This is actually an extension of a discussion that we had where we were talking about knees. And then that led us into a foot representation as we're pushing into the ground and how we would see a bunion evolve under certain archetypical situations. And then that led us back to the knee a little bit and a little bit of pelvis as well in regards to these force producing positions. One of the biggest errors that we tend to make that results in some of these negative secondary consequences like bunions, knee injuries and such is trying to produce force through an externally rotated representation. In an ideal world, we want to have situations where we don't have rotations taking place as we're producing our maximum force. So if I grab my pelvis over here, so if we're gonna talk about a force producing pelvis situation, we're gonna have the IR representation of the pelvis because there's no rotation going through the pelvis. That allows us to produce maximum force without a dissipation of energy. Same thing through a knee, same thing through a foot. It is only when we are not doing that where we're actually pushing through these ER representations where we get these negative secondary consequences. So Ian, thank you so much for this question. Truly appreciate it. It's gonna help a lot of people. Everybody have an outstanding Tuesday and we'll see you tomorrow.

Okay, so this goes back to Zach's question at the very beginning of the call where we're talking about the differential between the distal radius and the proximal radius. It's like you kind of get the same thing. It's like, yeah, I'm squeezing my knees together, but am I just increasing the differential between the proximal hip and the distal femur? If I have too much external rotation approximately, you're not gonna get the internal rotation into the pelvis. It's not gonna happen. But you can attend to this. You can actually see it happen in people that cannot internally rotate. Like you watch them at the hip, you can watch their hips as you put something between their knees and you'll see them externally rotate. You'll see them try to rock their pelvis back into posterior orientation right away. Just shut it down and start over.
