Okay. Hip flexion is an ER measure. Spine flexion is an ER measure. Yes. So let's use, let's use traditional hip flexion here. So have you ever taken someone's leg into like full hip flexion and compressed their thigh against their belly? You think that's hip motion? No. What is it? What's moving when you do that? How do you get a, like literally how do you get somebody's thigh to compress against their chest? Because in school, they told you that the hip joint has 120 degrees of traditional flexion, right?

Right.

Yeah.

So look at the foot representations and look at where your hips are positioned. You're going to go through because you're moving through space. You have to have some ER to move, but generally speaking, it's going to keep you biased more towards a middle representation. The more lateral you would step up, the more middle you would be. So don't forget about that.

Right, so probably outwards, outside.

Does that make sense?

It might be. So let's think about this, though. So let's consider the mechanics prior to the injury. Are they the ones that set them up for the injury? So you're going to have to make a judgment, right? You're going to have to say that I like this better. You get the videos of the guys, like the view from behind on the mound. And something as simple as looking at their drag mark, you know, and you look at the shape of the drag mark and you go, oh, he's hanging in onto his ER too long. And then he comes in, he starts complaining about medial elbow pain. And now you got the association, you go, okay. So then you take him through the process and then you're shooting the video and you see that drag mark start to straighten out and you go, okay, now I got the IR back. That might be one of those favorable things that you're gonna make a comparison to. I would just be really careful as to what kind of a judgment you're making with the pre-video saying that these are supposedly the ideal mechanics. Maybe from a performance standpoint, but it also might be a demonstration of their inability to manage their superpowers. So that becomes a money muscle in this regard when we're trying to untwist the tibia.

Yeah, because they can keep the bar level, but I just noticed now that they're twisting somewhere else to keep the level without orienting the whole body.

You're still putting force into the ground. The question is how you're accomplishing that because it takes relative motions to get to the position of pronation. You have to look at everything in a sequence. So to get the medial heel and first met head down to do that, I have to have a subtalar joint in the ankle-foot that allows that to happen so I can actually access that position from a relative position of ER to IR. If I stay supinated, I'm still putting force into the ground. It's just going to be a less than ideal situation. So if I get a runner that comes into the purple room and they've got a history of a fifth metatarsal fracture, you want to know why that happens? That's a focal load on the fifth metatarsal for somebody that could not capture a foot position with normal relative motions. So if they're in a much later representation of propulsion and they're trying to put force into the ground, they're trying to slow themselves down to put force into the ground. They're still going to do it. They're just going to use a much less desirable compensatory strategy. So again, that's a pelvis that's moving as a single unit into that anterior rotation to push down into the ground. But the foot that you're pushing down into the ground with, again, less than ideal distribution of force. It becomes a focal load, right? So maybe the focal load goes all the way up into a hip joint.

How many times you measured them?

Hanging my head into the steering wheel every day. Yes, absolutely. Some days you get those presentations that don't have a lot of stuff added on. It's very rare in my world. For instance, I had a patient that came in yesterday, and when I asked when this started, he said 1983. That's a long time. It's not like a guy who said two weeks ago he was deadlifting and tweaked his back. Those are the guys that are pretty easy to work with. When it's 1983, I was a junior in high school in 1983, and it's been really fun. But again, the representation you had was not an end-game representation. All you needed to do was make sure he went back on the opposing direction, and you immediately get the change. The nice thing is it's usually a very simple kind of representation. It's like, oh, I just need to move you back on that foot. So you do that offset squatting thing, and they go, that's all I need to do. And you go, yeah. Then they ask, what are we going to do with the rest of the appointment? Well, we can just socialize if you want. That's exactly how it went.

You're reducing the natural yielding that's associated by adding stiffness. It doesn't mean that you won't get a yield. It just means that you added some stiffness, okay, externally. And then that was.

The time aspect. I'm not sure what you're asking me. Like this.

Not as stiff.

Well, I don't know if they answered everything, but I hope it was useful. Okay.

It was fun to play around applying your model to what I saw. But one thing I was curious about: one of my lab partners was doing the scratch behind test, and I saw the head deviate towards the involved arm. My idea was when the spine rotates that way, it's compression, but this is like external rotation. Is it am I getting my cervical motion?

Sorry to hear that. It's okay. It's okay. It's your foundation. Always remember that it's a foundation that you build upon. It's an analogy for you to make comparisons with. So, so there's value there. There's value, but just understand that there's more than one filter.

Right, and even in the Olympic weightlifting example, it seems like if you look at the hip, it's squeezing inward, so it's more right, and there's a new sacrum. So that even seems like an example where it's just you have to look more approximately to see what's happening, right?

If she's dealing with pain related issues, under many of those circumstances, those are going to be at one of the extreme ends. So it's going to be an extreme expansion, which is high tension, or it's going to be extreme compression, which is where she's closing off the space. So when you're looking at the scapula based stuff where she's having that discomfort, is she pushed forward or is she expanding into that space? And then that's your call. Okay. And so that might be where you start to reestablish. I need to get her to turn in that direction to create the expansion because what she's doing with that scapula, and this is pretty common. You'll see like the almost the inferior angle of the scapula when you have somebody that's Goliath is that it's almost like it's pushing down on a shelf of a rib. So now you have an idea: oh, we got to move that back. Okay. So that's a delay strategy on that side. That's why I need to drive expansion. So that's a turn in that direction. So when we talk about propulsive phases, she's probably got to capture an earlier propulsive strategy.

It should. People waste it, but people waste it because they think that they automatically get tomorrow.

So whenever there's a change in acceleration, there's a change. So acceleration is defined as a change in velocity. So if I have a change in acceleration, so if acceleration is increasing and it will increase either positively or negatively. So what people call deceleration is just a negative acceleration, that's an increase in acceleration. And so as I have my biggest space, my biggest expansion is where the velocity is demonstrated to be greatest.

So let me show you where max, where max is. Okay. So as you step forward with the left side, so it's still on the backside. No. So yes. Yes. So, so this foot is just about to hit the ground. So your left foot is just about to strike the ground. So I'm stepping forward. So my sacrum is facing the right. I am creating the delay on the right side so this leg can get out. As soon as this foot starts to hit the ground, I have to start to make the turn. But here's when we talked about the interrotation wave that goes up your body rather violently. I'm going to be in this position. So this is a new position. So this is, this is where you see this, this violent jolt. Again, if you watch, if you watch the throwing in slow motion, you can see the jolt of the body, right? And so they're hitting this point. So this is where the sacrum has to stop moving. The only way that I can do that is to create a new tained position with internal rotation. So for a split second, So think about this, as I'm about to lean on my left foot, sacrum's facing the right. As I hit max propulsion in the direction that I'm gonna be throwing, boom, it locks it in. It locks it into this internally rotated position. This is internal rotation. This is forced downward. This is a nutated sacrum. No movement occurring at all. Because if I'm moving, I dampen, and then no force goes into the ball, or a limited force goes into the ball and I don't throw as hard, okay? So I go from right facing, dead center, interrotation, and then it follows through. You see it? So for you to be an effective bowler, you're going to have to be able to hit all three positions. This is how you figure out what to do from an exercise standpoint, because if you break your throw down, you can see where your limitation is. So if my limitation if my limitation is at max propulsion. So if I'm soft or I dampen through that middle phase, I know I need to do exercises that hold me in this position, high force production, very symmetrical in regards to the exercises. So this would be a situation where a deadlift would be very, very useful or jumping activities would be very, very useful with a symmetrical stance, because this is where I need the highest force production. If I need to create the delay to allow the throwing arm to come through, then I just got to select activities that are turning the sacrum to the left in this early propulsive strategy. So now I'm using a split stance with my with my front foot on a ramp to create this delay representation on the left side. So again, what you have to understand though, is you have to understand what you're throwing mechanics represent, where the limitation may be, and then you select your exercises appropriately. Does that help you?

That makes sense.

Yeah.

It probably was like, yeah. Exactly. Now. But there's a great test retest for you to let you know that you're making a favorable change when you do. If she's wide and she's compressed AP, we're going to try to rely on some gravity here to try to create some of this expansion. The simplest, easiest thing to do is to put her on her side. The minute you put it on her side, gravity pushes down, and the side of her that is closest to the ground is going to get compressed into the ground. And what that does is it creates a spread anterior to posterior. There's good research on this—it's like, all you got to do is lay somebody on their side and they get bigger front to back. So that's advantageous. Now, she's going to be flattened out front to back, so she's got a lot of muscle activity on the front side, she's got a lot of muscle activity on the backside, and there's nothing on the sides to squeeze her in, which is one of the reasons why we want to put her on her side. Now we want to start with some gentle, and these are not full rolls. This is just getting her to start to roll forward and back through a small excursion on her side in the most relaxed manner possible. What you do is you put her on her side, you support her head on whatever you got—air pads or whatever—and you want to make sure that the head and the neck and the axial skeleton is in a nice straight line. So she's rolling around her long axis of her axial skeleton. We're just talking about small excursions. So this is lazy. It's slow. It's boring. And I would put it on the level of being meditative. If you can kind of promote it in that manner, then it becomes useful to a lot of people because chances are, sounds like she's carrying a little bit of anxiety associated with what's happened over the last year. She's got her husband that she has to be a little concerned about. So again, that's going to be demonstrated physically as well.

So in most cases, like I said, I wouldn't give the suitcase dead left to the accountant that's never played a sport and doesn't know how to move, because again, his system is going to be defensive under those circumstances, and he's just going to try to prevent motion. So I got to put him in a place where I've reduced as many of the forces possible on him to allow him to be successful. So again, I lay him down, I reorient gravity, I take it out of the equation, and then I can teach him some sort of movement vocabulary is what I call it, is basically I have to provide him cues so he can start to feel different things that allow him to sense when he is moving because chances are he doesn't have that where my my athlete or my chronic exerciser that's been exposed to many different things, I'll have to do is say, hey, do this. And they immediately know what I mean. So, so there's a little bit of experience that plays into this. And there's a little bit of an understanding of what the probabilities are. And that's, that's what experience provides. It's like, it's like, think about it. It's like, you've worked with a thousand different people. You get all these different presentations, but then you start to see these, these things show up where that sort of guide your thought process. Whereas if you only saw 10 people, you wouldn't be able to make those same judgments. Does that make sense? Yeah, no, that all makes a lot of sense. It's a very great answer, but because we're dealing with a very gray situation because there's so many unknowns. So one of the things that I do as I'm talking to my clients is I just ask them, I say, what sports did you play in school? Like, you know, it sounds like, sounds like conversation to them, but literally what I'm doing is I'm trying to figure out what is their, what are their movement capabilities? What have they been exposed to? What do, what will they understand? You know, and then maybe I can speak their language a little bit. So if I had like a, if I had a jujitsu player come in and he's talking about like, I got this hip thing. And then, so then I can go, it's like, oh, you know, when you do that, you always notice that you kind of hip escape really easily to one side. And then you try to go to the other side and you can't do it. He goes, yeah, it's like, okay. So that's literally what we're talking about. So now I can take his jujitsu and I can make it one of his exercises. And I say, I need you to practice your hip escape to the opposite side. And then that teaches him to create all of these different strategies through the pelvis and through the hip. And so now that helps me select what I want to do for him because it's meaningful to him. And it's useful at the same time, but he understands it. Okay. So a lot of this is just kind of relating to the individual and getting an understanding. Now, I think he said all that. Okay. I fail a lot. Okay. Cause I always try, I always try to hit the home run. If I can give somebody one exercise that addresses three different concerns, I will try to do that first. Okay. Again, it takes someone that's more coordinated than somebody that isn't. So, so like I said, again, I pick on the 45 year old account and that's never played a sport cause it's kind of easy to do. So under those circumstances, I tend to not give them the most complex of exercises. But if I have an athlete that comes in, it's like, Hey, we're going to go in the gym and we're going to mess around with some, some cable activities. Whereas with the accountant, you know, he's laying on his back or he's laying on his side or I'm teaching him how to roll like literally teaching, teaching somebody how to roll, you know, because they, they don't have that capacity based on their physical shape. So, so does that help you at all?

So let's talk about that. As people move through space, they go through expansion and compression strategies. We want a representation of what that looks like. Because we're short on time, I'll direct you to a few things on Udemy. Go through some breakdowns. I did an extensive half-kneeling video and we've done split stance activities. From those, you should see that there's a bias toward expansion and external rotation in certain positions, and internal rotation and compression in others. There's a visual representation of these. Take that concept and apply it to your coaching eye. When you see someone in a split squat with one hip higher than the other, they're not acquiring internal rotation. Your program must include activities that capture internal rotation in that position. Modify ipsilateral versus contralateral loading, foot elevation, rear foot elevation. Move them off the sagittal plane for side-to-side motion. There's a difference between backward and crossover sled drags for different pelvic orientations. Consider this. Understand where external and internal rotations should appear, and you can do much. It takes practice—you'll make mistakes, as will I. Don't hurt people. Always do safe experiments. Apply an intervention, see what happens. If you do it correctly and they have adaptability, they should change quickly, and you can see the difference. Always have a comparator. Complex movements are great because you can see improvement. You just need a representation of what you're looking at, what it means to you, then apply an intervention and observe.

Okay, so someone who struggles with compressive strategies posteriorly at both C6, C7 and at the top part of the sacrum of the sacrum. For management strategies and they've kind of got tightness all the way down the right side of their back as well. What would you suggest is the top priority when working with someone who's got like this down the wall.

The client I have right after her is a second player or second content story strategy. He is a big guy with a wide ISA and definitely in obese categories. And he has a big belly kind of thing.

Well, I wouldn't go that way. 16% is kind of an attitude. It's a belief system. It's an attitude versus the truth. It's a lifestyle. Yeah. The 16% lifestyle, that we do said, Dave. That's funny. So there are no norms in regards to movement. None. There are averages, which is what we compare things to. Norms are like your normal movement and my normal movement are different because we are different people. We have different structure. And therefore our movement will be idiosratic because our capabilities are idiosyncratic. We use comparative averages. So we have a point of reference for comparison. Chasing an average for a superhuman may not be the best solution.
