To turn them to the left.

Yes.

So you're going to get the ER-ing of the ulna, the ER representation of the radius all at the same time. Basically what's going to happen is, if you use the ulna sort of like as a midline and take that space that goes from ulna to the lateral epicondyle and just compress all that forward, that's kind of what you're looking at.

This is going to come down to intention. If you had an Olympic weightlifter, you have to access a vertical position. There's a depth they must reach to get under the bar. Under that circumstance, you can't force somebody into a position they do not have access to. Hip structure becomes a problem, and orientation becomes part of the problem. There's going to be toe-out and ER orientation. You can superimpose the IR, but that's pure execution. You have to take that into account. Just like when teaching the lifts, you have to consider your expectations for reacquiring movement and make accommodations. It's just to whatever degree within that context. Performance shows you the limitation. You know that some lifters will never be able to squat with anything less than a massive amount of toe-out because they're trying to acquire a position with a specific physical structure that won't allow certain things to happen. The greater your capacity to access the ideal puts you on the Olympic team versus just being someone who likes to do the lifts.

OK. That's when you do it. And that's when it's successful. So when I need the ER representation, when I need the ER representation of the lower extremity, okay. So if I have a compressed extremity, that's an extremity that has more IR compression, right? It's some more downward compression. It's like, if I have to alleviate that, you just did the activity that's going to provide you the solution. Good morning. Happy Tuesday. I have neuro coffee in hand and it is perfect. All right. Already a productive week. It's only Tuesday. So let's take straight into this Q&A. This is with Dante. Dante had a question in regards to connected tissue behaviors and how those influence activities such as rolling. And while we use rolling to such levels of effectiveness, we have to consider the fact that we've got a position where we're altering gravity. So that's going to immediately change the influence of internal forces, external forces, and our response to those. And so right away, we get a tuning down of muscle activity that we typically are going to be trying to influence to restore relative motions. We have altered the internal forces, so the direction that those take place have also been altered. We also have the pressure of the ground and the associated gravity pushing down, which is going to influence our motor output. Take into consideration the fact that all of your guts are falling towards the ground. That's going to promote some shape change. So we get a really big bang when we're talking about these rolling activities. The one you select is going to depend on what the needs are of the individual, obviously. But we've got a lot of potential influences here with rolling activities in regards to what type of an output that we're going to get. So Dante, thank you so much for asking this question. Everybody have an outstanding Tuesday and I will see you tomorrow. Go ahead, Dante.

And you know, if you don't let the kid fall down, scrape his knee, get a little dirty every once in a while, he's not going to know that it's going to be okay.

OK, so you're not wrong in regards to just manipulation of the magnitude of load, but you also have to take into consideration the rate at which you're going to perform this activity if you're trying to emphasize an element of the connective tissue behavior.

Good. So I have a question about the knee and the propulsive cycle of the knee of what it does during a squat. And also what it does when you're checking the heel to butt measurement, if there's a difference between those two.

Yes, yes. There's a little bit of a difference in the application for sure. Because when you do the reverse hyper, you just don't have the ability to drive as much proximal to distal force. So it doesn't go through. With the back extension, element because of the foot plate you're able to deliver more more force under that circumstance for sure right so what do you think is the if you were to if you were to hold them

Okay. And she's got to make a left hand turn.

Please.

The easiest way in the whole wide world that everybody does at some point in time if they're a human being.

Okay. So look at your feet on the ground. You've got a lot of that bony bend towards the ground. Right. Okay. So if we were going to do an oblique sit, we would want to put pressure on your ischium to bend it back underneath you because it's bent out. You see it? Yeah. So again, you just think about like, how would I want to... So if I wanted to bring a foot back to where it was actually squared calcaneus to the ground, I have to push from the outside edge of that heel towards the medial aspect to square it up. Same thing with the ischium under that circumstances. I got to put pressure on the lateral aspect of the ischium to push it towards a normal representation of that, that ischium. Okay. Cause the ischium is bent. The ischium is bent just like the heel is. Now, do you understand the placement?

Yeah, the backwards step two. I didn't get as good a result with that, but when I went to the lateral, the sideways one, I got a much better result. Now, would that be indicative that I don't have the room in front of me, but I do have the room further? Quite past year. Yeah.

So let's be really particular about the stepping we're using here. Michelle has a chop, a squat variation, a carry variation, and now we're giving her a sled drag. If I want to be coherent with everything we've talked about, how do I want Michelle to step when she's dragging the sled and moving in the posterior direction? What step would reinforce her compensation, and what step would help us capture the foot cues?

Well, you're both. You're both. Okay. So inhalation and exhalation are always happening at the same time. Okay. So you're either partially full, partially empty, but there's always air in you and there's always a deficit of air. Fair enough. Okay. You're always inhaled and exhaled. But now if I say blow out all your air and breathe in 75% of your lung capacity, you are now biased towards an inhale. Does that make sense?

And again, it's like, are there times where we don't have the four points? Absolutely. But you're not using relative motion at that point in time. So as you propel off of your foot, where you're in the latest of late phase propulsion, you're going to lose the fifth metatarsal. You're going to lose the fifth toe. Your weight's going to go to the first metatarsal and the big toe, but I got news for you. I'm going to deadlift at that part out. You do not have relative motion at that point.

Oh, sweet. Do you do the... A little bit of that. Yeah. Just when you start walking, you can feel the difference after I've done it. Yeah, yeah. You'll most likely have a little bit more internal rotation on the lead leg. Yeah. Fun fact: I've seen Saturday Night Fever 150 times. True story. It's one of the greatest movies ever made.

Yes.

Yeah, exactly. So you have to be in a position that would promote that. So if you have a hip that's resting in an extreme ER representation, do you think you're going to make that bony change that you want?

I just wanted to get a clearer understanding on the open versus closed kinetic chain. And because I know, I know.

Okay, so if you perform an intervention and you think you coached it well and you think that they understand what you want and you get the appropriate cues, then you would have to do something else. And that's just kind of logical, right? So, and again, that's the difficulty at first. This is where experience and repetition comes into play. So if you're, let's just say you're seeing your very first client. Okay. First client ever. And then a couple of years later, you're seeing your 500th client. Which one do you think you're going to do better with? Right, because you've got more repetition, you've had more exposures. And so your understanding of what's possible and then what provides the best influence in most circumstances is just you're just more refined in your intentions, your understanding. And then you'll know better whether they're understanding what you want as well. And you'll still screw up. We always do, right? Because nobody's always perfect at this. But the point is, there's an element of experience that goes along with this. It would be really nice if there was a cookbook that says, rule number one, to know if you're doing everything correctly. Rule number two, and there's certain things that we can say that are principled. I need to get the correct inputs to get the right output. But it's going to take some time for you to understand whether you're doing everything to the best of your capabilities. And then as you learn, those capabilities will improve as well. So a lot of questions that people have are associated with time. Hey, Taya, can I pick on you for just a second? So were we talking about heel to butt measures and stuff last time? And I said, after you do the 500, you're probably going to get pretty good at identifying what you're looking at. It was something like that, wasn't it? Like we were talking about, how do you know when you have the Patella moving laterally? It's like, well, do it 500 times and then compare each one to the next one. And that's how you're going to gain some experience. And so your questions and this is kind of along those lines. It's like, number one, do the best you can do, understand the things that you can execute, pay attention and do a lot of them, right? And that's where your confidence will grow. That's where your understanding will grow. And then as you do that, you will shift probabilities in your favor. You will always have failures. But the failures will teach you a lot if you pay attention. But see, that's why this is hard. We can talk like it's easy, but it's always hard.

I think that's what we're building.

The word 'easy' is always problematic because when you say something is easier, you get the person who walks in and it's not actually easy. You need to consider the position of the center of gravity—whether it's forward or back—and the direction in which it's moving up or down. So if the center of gravity is down and forward, with 'down' meaning internal rotation, you have to push into the ground much harder. The question becomes how you achieve this. You can't just look at the archetype; you must consider the relative size of the thorax to the pelvis and the starting conditions of the proximal limb connection. For example, if you have a very wide pelvis and a small thorax, and your center of gravity moves down and in and forward, you'll need a large inward turn, resulting in a different knee structure. If you try to avoid that position with a different axial structure, your strategy might change, such as using a varus approach to push the center of gravity more forward and less down, keeping you more upright and causing more external rotation from proximal to distal, leading to what you might call a varus representation. Thus, two individuals with the same archetype might use different strategies based on their axial skeleton configuration because one requires more downforce than the other.

But now I'm trying to think of what will make for a thicker or more flaky cupcake, I guess it's because I'm trying to think of how magnitude of force, sorry, the components of force, which I don't know yet what are the seven. I need to go do my own work on that, but how direction, duration, frequency, variability, right? Yeah, I am. I have the rate of coding to acquire all that information. Could you, but could you go over that a little bit for me here? Which part? Like the seven ones, just so I can.

That would be a refrigerator turn, wouldn't it?

So you have to consider the parameters of the activity now, right? So you have to say, okay, how much load do I have? And then what am I constraining with my attachment to the sled? So pulling a sled with your right hand handle versus taking a strap and putting it around the pelvis are not the same thing, right? So you're immediately constraining the thorax. So you're reducing relative motion in the thorax by having them hold on to the handle. It doesn't make it wrong. Just means that I know that I'm intentionally constraining it. I'm actually moving them towards a stronger middle representation because I'm taking away the turn that they would have available if I just attached them to sled with the hip belt, right? So I should expect that I would get more thorax activity. So again, I would expect that I'm going to have that load. Now, I can manipulate the degree with which I'm going to produce that IR by load. So the heavier the load is, the more I'm going to push them down into the ground as they're moving sideways. If your intention is to increase the relative movement, then typically I do not constrain the upper extremities for that reason. Because I want to create the turning capability through the thorax and drive it down into the ground as I push off the right foot like you were talking about, but I also want to create the delay strategy as I'm stepping out and bringing the foot over top.

Yeah. So once you get some movement that you want, can I tell them to just pick the arm up off me and hold that position?

Yes.

The real kicker here is the ability to apply force downward. And to do that without a compensation requires access to internal rotation. Depending on how you determine whether your client has that capability, that's entirely up to you. Some people can throw people down on a table and understand how to measure on the table; I don't think it's necessary, first and foremost. But there are certain activities that might allow you to determine this, for instance, like watching somebody perform a step up would allow you to identify the excursion of a hip joint that must move through internal rotation to be able to do so. But anyway, that's going to be the number one thing that you're going to make sure that you represent when you're bringing somebody to stand. Otherwise they will be using a compensatory strategy. If you know that and you understand how to manage it, then more power to you. I think there's a lot more options under those circumstances.
