I don't know. We had a girl that made a pretty significant change in about four weeks. If you break a bone, Michelle, how long does it take to heal? Yeah, it's true. It's a good point. It doesn't take that long, right? You just need enough stress over time. Okay, so let me ask you this. So I got braces on, right? You can move a tooth pretty darn fast. That's very true, yeah. So when you look at a dry cadaver as a representation of human behavior, that's a misrepresentation that is in a normal dynamic human. So again, it just gets misrepresented as to what is possible. Good morning. Happy Friday. I have neuro coffee in hand and it is perfect. Okay. It's a good morning. We woke up this morning to check the box scores. Josh Limblom, our boy at the Brewers, got his first win of the season, seven strikeouts. So a very solid appearance there. Also I've mentioned Lomo, Logan Morrison, A pinch hit, one for one, so very, very exciting for both of our guys at the Bruce, by the way, you gotta check out Lomo's Instagram, it's Lomo Graham. If you're a fan of coffee, baseball, and personality, so check him out. We're going to lead into the weekend with a really good question that I think will be helpful for a lot of people. It comes from Mikhail from Russia. So that's very exciting to have somebody send a question all the way from Russia. It's a really good one. So here we go. If someone is standing on their left leg and the other leg has the hip and knee flex to 90 degrees, and you see the standing leg turn into excessive external rotation and also abduct an extended shaman you for thinking in the imaginary planes, but that's okay. Why is that? And then what do you do with this? So this is really, really useful because it's very similar to my load propulsion test that I teach at the Intensive, and it's also going to have some similarities to the Gillett test. So if you're one of those people that uses those motion palpation tests as if you're evaluating the secret iliac joint, excuse me. This will also be helpful for you, but let's describe sort of what we should see under these circumstances and then What you're seeing and then we'll say well, okay, what do we what do we do with this? How do we improve this situation? And so what we want to think about is So we're starting from a standing position, so we're not propelling ourselves forward, but we're sort of in this middle range of propulsion. So we're going to create a little bit of a delayed strategy where we're probably going to be a little bit more inhaled by us, a little bit more ER'd, and a little bit of counter-neutation. So we're going to create a yielding strategy on this posterior aspect of the pelvis, because if we're not propelling ourselves forward, we're going to create a delay strategy here in the pelvis. If you recall, in this first early phase of hip flexion, we're still going to be in that ER bias, but as we approach 90 degrees, we're going to move towards an IR bias. So as the foot breaks the ground, and this would be our advancing leg if we were walking, We're going to create a bigger delayed strategy. So we're still going to be concerted at yielding on this standing leg. So we're going to be starting in ER. But as we break that 60 degrees or so of hip flexion, we're going to start moving towards IR on both sides. So this leg will be slowly advancing forward towards that really strong middle range of propulsion in the stance leg. And this leg is going to be approaching 90 degrees of deflection, which we also know is going to be IR. So what we should see is the pelvis moving from a slightly ER position to an IR position. So we're going to see some mutation of the sacrum under these circumstances. And we're going to be approaching that IR position. And so if you've ever worked with kids and you have to do A marches or A skips and you'll see all sorts of sort of mobility issues or substitutions and you'll see them turning into or away from their hips or you'll see some side bending, these are the kids that can't really create this IR position of the pelvis where where they have to have a constant or pelvic diaphragm and they can capture this internal rotation, which is the really strong propulsive positions. And so again, this is why this position becomes very, very useful. Because when you start to see these substitutions, you know you've got somebody that cannot capture this internally rotated position. As we take the hip past 90 degrees, we're gonna re-er under both circumstances. So now I'm gonna move this hip towards a later propulsive strategy. And I'm gonna have this hip moving towards an early propulsive strategy. So now I'm gonna create a delay on the lifting side leg. So as I break this 90 degrees and this goes into a deeper hip flexion, now I'm gonna see this moving into a much more erred position on this side. So that's what should happen. So I should see the ER, the IR, and the ER strategy of this normal propulsive phase. But what you're seeing, Mikhail, is you're seeing that very, very early representation of this external rotation on the standing or the support side leg. So you have something that's moving into the later propulsive strategy too soon. And so that's why you're seeing this really, really strong ER position when we know that we should be approaching IR under those circumstances. Now, so the question is, it's like, okay, so what's going on over here? Am I seeing an anti-orientation? Probably not, because the anti-orientation will actually steal my ability to yarn this hip. So again, most likely we're just seeing this later propulsive strategy too soon. So what do we do about it? Well, it just so happens that we've been talking about this during the week.
