Chris: The last couple of episodes, we've talked about quadruped and half kneeling. We're going to keep the theme of positions for activities going with this one. So if you have someone that can't access quadruped or half kneeling, the thing to try oftentimes will be remove some of the gravity out of the situation and put them in sideline, for instance, to try to use the ground, use gravity, use the physics of the situation and the task to create the spaces that they may not have. So we're going to talk about. what the actual demands mechanically are of Sideline, what it produces, what it can create when it's used correctly, how your structure determines what you're going to see when you put someone there. And we'll talk about that and more on this week's episode of. All right, real quick before we get into this, the YouTube analytics bot let us know that many of you are not actually subscribed to the channel. So if you could go ahead and ⁓ subscribe to the channel. ⁓ you're one of the people also that's on Apple podcasts or Spotify, be really helpful if you could leave us a review, five star review. That would help us. That's what my Uber driver always tells me. goes, five stars, please. Bill: Hahaha Chris: Five stars. Okay. So getting into sideline, let's talk about what sideline actually represents. Let's maybe frame it from the perspective of what you or I might've used sideline for 10 years ago. What we use it for now. that game you got to get in the time machine in your head, put yourselves in shoes of Bill from, maybe 2008, like go back to like when, ⁓ yeah. Bill: ⁓ man, it's like I don't remember last week. Chris: really reach in. yeah, let's let's see. Let's get let's get into it. Let's talk about what it represents, where the thought process might come from, what's really happening, that type of thing. Bill: so if start with 2008, ⁓ probably thinking the lines ⁓ of unilateral activity. Right. And for some reason, like clamshells pop into my head. ⁓ That type of a of a scenario and probably more lower body driven, I think. ⁓ Then how would look at it today. Without concern. Chris: Mm-hmm. Yeah, I think it was just a matter of, yeah. Bill: without concern of whether somebody can actually acquire the actual sideline position. And this goes back to, so if I didn't rationalize whether they could even access the sideline position ⁓ and they couldn't, I'm immediately putting them in compensation land. And then I'm gonna ask them to perform an activity which could be useful in some position. but I'm putting them in a position where I'm already driving a compensatory strategy. Therefore, the effect of the intervention is compromised. And that becomes the biggest concern, I think. And probably didn't consider that a long time ago. Chris: Yeah, I think... I think the main reason, the main reason people would use it is just because it's an easy position for people to get into regardless of the situation that they have come into the door. So if they got a knee, they, yeah, it would stand on paper. I think people would expect that, right? They lay on their side, do their ⁓ shoulder external rotations, pinching the towel. They do their clam shells. They do their, ⁓ Bill: It seems to be. It seems to be. Right, right. ⁓ huh. Yeah. Yeah, don't pinch the towel. Don't pinch the towel. huh. Yeah, yeah, yeah. It's very, it's like the thought process is like, okay, it's unilateral. It's very isolative. I'm working on a muscle kind of a thing. Right? Yeah. Well, so when we say, when we say things like, like, people can't actually acquire this position, people go, well, they're laying on their side. Chris: They do their straight leg, hip, AB duction. Yeah. Yes. Yeah. And just an easier setup for a lot. What you would consider it be easier. Bill: And then the assumption is like, okay, that is now effective. And what we have to consider is like, okay, we have contact with the ground that's going to influence the actual behavior. And therefore, like the joint position that I'm actually using, the ground contacts, that is a requirement of this actually being an effective position. And if you don't consider that, then you just say, okay, you're in sideline. ⁓ It's like, well, but are you? Yeah. Chris: Right. So what, like real quick, what are the things that people, how are people going to present in sidelining and you know that they can't do it. They shouldn't be there. Bill: So one of the big issues with with laying on your side is we're orienting the, let's just think axial skeleton for right now, we're ending the axial skeleton on an orthogonal. So gravity is up and down. that requires, if I'm approximating an orthogonal, that requires some measure of internal rotation to actually access that position because it creates a shape. theoretically, if you have the capacity to, it would actually reinforce the internal rotation. And if you don't have internal rotation available to you, so if I don't have enough internal rotation, say in my hip joint, and I roll over to my side, well, that requires the hip to internally rotate, that requires the thorax to expand into your posterior. If I have a ground contact through the shoulder, I have to have a scapular position and an upper extremity position that would actually allow me to lie in sideline without a compensation. compensation. I accented the wrong syllable there. Solable, yes. ⁓ So I have to have some element of internal rotation available. If I don't, if I don't, so let's just look at hip and pelvis orientation. If I put somebody in Sideline that does not have access to internal rotation, I will do one of two things. I will orient the pelvis further into anterior orientation, which is a substitution for internal rotation. Chris: Syllable. Bill: Or I will drive an ER compensatory strategy to try to make a space that would allow me to ⁓ access the position without internal rotation. So if we were to looking ⁓ at a lumbar spine, ⁓ the IR compensation would be an increase in that lumbar curvature anteriorly. So ⁓ legacy traditional perspective would be it would increase the lower doses. Right. If I'm using an ER compensatory strategy, I would see the bend in the opposite direction. So this would be like a rounding of the lumbar spine pelvis kind of tucked under as it were. And so if I put somebody inside lying in that position, I can immediately identify whether that internal rotation exists. Because if I don't see a magnification of the IR, I don't see a magnification of the ER then it's highly likely that that actually might be a useful position. Chris: Right. So, and let's talk about that a little bit. The use of the position, what we're using the position for, I think pretty simply is looking for a sort of systemic shape change, putting yourself in a position that allows for, if there was a lot of anterior, posterior compression, which we're dealing with with a lot of compensation, it allows the gravity and the actual position of the floor to allow that AP expansion. Bill: Uh huh. Uh huh. Yes. Yes. Yeah, there's a great study on this actually. ⁓ And I believe the lead author is Takashima. And so what they did is they put markers on the thorax. ⁓ I believe it was sternum zyphoid umbilicus. Don't quote me on that. I think that's right. And so what they did is they put people in different positions. They basically just rolled them into different positions. And when you see somebody in supine, Chris: I think so. Bill: you see the anterior-posterior compression. So you think about like gravity pushing down on the rib cage. And so if I push A to P, so I'm on the ground, so there's my posterior pressure, I gravity as my anterior pressure, and I spread out, literally spread out sideways, right? And that can reinforce that anterior-posterior compression if it pre-exists. And then they roll people to their sides, same markers, and you see this immediate anterior-posterior expansion. which is usually favorable to recapturing relative motions. So that gives me the space that reduces the anterior posterior compression that would be associated with all that anterior posterior muscle activity. And so that makes it a very favorable position to work in when I'm trying to recapture relative motion. Chris: Yeah, and it just gives you a greater potential starting point. So you have more, you have more just from a physics potential and kinetic energies. Bill: Absolutely. Yeah. Reduced pressure, immediately reduced pressure. I now have space for movement. So again, very useful. Yeah. Chris: Yeah. So that's, that's the reality of what it's used, should be used for what we reconsider that you're using it for. think that maybe hitting on some specific examples, I have a couple in mind just because I just worked with a new person who we were struggling with sideline just because it kind of hurt. was sort of pointy. Anytime someone's got, anytime someone's got a, anytime someone's got a, an Ilium point, like a hip pointer feeling or like their greater trochanter hurts or. Bill: ⁓ huh. Yeah! ⁓ yeah. Yeah, yeah, yeah, yeah, yeah. Chris: They feel like a pinch in their shoulder or their rib cage feels very pinchy on the side. Those are all indications to you as a coach, as an observer. Another one is like a knee that can't contact the ground even though they're laying on their side. Bill: Correct. Right. So this is big, this is big, because everything that you're explaining is a representation of somebody that does not change shape as we described, right? So the reason that the trochanter feels heavy and pointy, if you will, is because as they do attempt to roll to their side, they still have the antipresitive compression which spreads them out sideways. And so then the prominence, they're literally balancing on the point of the... Chris: Yeah. Bill: the greater trochanter versus able to access the internal rotation in the hip. So right away you're thinking, okay, I got somebody that's probably not going to be able to access this position effectively. You mentioned knee contact. So a lack of a knee contact. So think about being in hook lying, rolling to your side. So the ground contacts represent the access to the shape that will allow the superposition of the internal rotation. when they're laying on their side. And so ⁓ I will have extremity shapes and positions that don't allow those effective ground contacts. If I don't have those, once again, don't have the right shape change, can't superimpose the internal rotation that I actually need to effectively lay on my side. So like they'll complain about like shoulder pain, they'll complain about the hip pain. And then you as the coach are working to access ⁓ a greater trochanter, I do want a contact there. I just don't want that to be the isolated contact in that circumstance. If I spread that out between a lateral knee contact and a trochanter, now I do have effective ground contacts. I have a distributed load ⁓ through that extremity. Chances are, if I do have those effective contacts, I have the pelvic shape change that would be associated with the anterior-posterior expansion that I do for intramortation, which means I now have an ilium. that can move from an ER to an IR position and that will trickle up into the thorax. And then I get my anterior posterior expansion. I'm no longer laying directly on the humeral head, right? And I have the ⁓ scapular and humeral position that will actually allow me to lay in sideline. Chris: Okay, so those are some of the considerations to make about using, what the position might be used for, what the things that you're gonna use to audit that position. say they don't have any of those symptoms or feelings and you see that the knee is resting on the ground, there's sort of a fullness to their right, the bottom side of their thorax as it sits into the floor. ⁓ There isn't any sort of, you don't see like a shrugging of the shoulder to try to get it out of the way. Bill: Correct. So that's a cervical spine compensation for the lack of internal rotation, just like we talked about with the lumbar spine. Chris: Yeah. And then, before we get into, cause I want to get into where it fits in terms of programming and when we would use it in relation to the two things we've already talked about quadruped and half kneeling, because we can just refer to those really easily from the last episodes. Let's talk about what other considerations need to be made, if any, for the wide and narrow spectrum of archetypes. we do, are wide, different considerations for wides versus narrows. Bill: Sure, sure. Okay. Well, we always have the anterior-posterior compression to be concerned with. So if I have a wide ISA that would typically be biased towards internal rotation and we had access to relative motions, what you're going to see is you're going to see a structure that can sideline in a more orthogonal position. So this is a greater degree of bend in the hip, greater degree of bend in the knee and still capture those contacts. So now we're sitting on a chair. We tip the chair back all the way to the ground. And then we roll it to its side. so that's going to be ⁓ more accessible for your wide ISAs. Your narrow ISAs are going to be biased more towards ER. So they're not going to capture that orthogonal position to the same degree that I would see in the wide ISA. The simple solution there is we would use the hook lying representation rolling to the side to be more effective for the narrow ISA. So this is, we're dropping the hip out of that orthogonal angle. We're dropping it below that orthogonal. And then that would allow them to capture the lateral knee contact, greater trochanter scapular position in a little bit lesser degree of the internal rotation that the wide ISA would be able to access. Chris: Yeah. Right. So we'll get into that. We'll get into that transitionary sort of perspective, the three quarters position, the transition between hook line or supine to sideline in the next section here. But I wanted to take a second to the, we've gotten comments before about how you and I sort of talk funny and it might not be as easy for a general audience to follow. And we're okay with that. Bill: Mm-hmm. Right. Correct. ⁓ Chris: And we want, I wanted to address that a little bit here. This stuff, we're, we're trying to work with practitioners to make them into the best possible practitioner they can be. And that's going to take a certain type of practitioner that wants to be challenged, can, a perception of their own inadequacies with a lot of this stuff. Like we've all experienced and they want to put themselves in a position to really have to like learn this stuff. So If you want to dig deeper into any of the things that we're talking about, and the last part of this conversation has been useful to you or provocative to you at all, then going to the UHP network that we've created and also taking some of the courses that we've, that you and I have developed to teach principles and concepts of this stuff, to teach the assessment approach. Like that stuff is available now through the UHP network, through education.uhp.network as well. And we have a bundle going where you can get both courses for a discount. So if that's interesting to you, then please check that stuff out. And there's my little ad spiel there. Hashtag ad. Okay. ⁓ Also, you know, the other two episodes, like if you want to take, if you want to take a second and go watch, or you want to pause here and you want to go watch the quadruped and half kneeling episode, that'll be good. Cause we're going to reference it now. So you can kind of come into it with some momentum, but Bill: There you go. Chris: thinking about it from the perspective of when we should use this position, when we shouldn't use this position, what to do if we're trying to get into this position. I think we've already hit on a couple of examples that we can elaborate on. Let's talk about first where this would even fit in someone's activity program or intervention sequence. Bill: So when the goal is to require relative movement, that is, if we just think about like frontside mechanics, if you will. So this is my ability to, ⁓ if I was just walking, if I took a step forward, I land my foot on the ground and then that. that internal rotation superimposes on that shape. So the initial shape is an external rotation shape. I land on the ground, there's my downforce, internal rotation is downforce. And so I can accumulate that with relative motion. That allows me to absorb energy, that allows me to distribute that energy effectively over a broad area. And so ⁓ relative motion sort of lives in that space. And so when we're using sideline, the reason that those contacts become so important, so we talked about the knee and the trochanter and then the scapular and upper extremity position, the expanded representation of the pelvis and thorax and the anterior posterior dimension, those are spaces that allow us to absorb that energy. Because what actually happens then, the next thing that would happen would be the system would naturally compress under those circumstances. That's a normal... response, we wouldn't want to land in that compressed position because that would indicate that we don't have access to the ability to superimpose internal rotation and external rotation that affects our ability to absorb energy. And so now we get stagnation of that mechanical energy that passes through our body and that can result in movement limitations that could result in pain that could result in load on structure. And so what we're doing is we're trying to put people into a reduced gravity situation. to teach the system to, again, superimpose that internal rotation on external rotation gradually. And so we take the gravity out of the situation by taking them off the vertical, we put them on the horizontal relative too, and then we can again gradually ⁓ re-educate, if you will, the system to not overuse ⁓ a great deal of muscle activity because they don't have to, because they're not upright. ⁓ We don't have the gravitational load from the superior aspect of the system anymore. We can maintain some measure of that expansion that allows them to gradually ⁓ absorb energy and the internal rotation versus putting somebody right up and putting load on top of them, ⁓ which is going to compromise the ability to require that relative motion. Chris: Yeah. So the, the lack of ability to get in the quadruped or the half kneeling position is there was you're watching the response from when you load the system. And if, if there isn't this able ability to distribute the load sort of up and down and energy kind of goes down and out and flattens laterally if in a way, if you will. Bill: Right. Right. Yeah. Yeah. Chris: instead of being able to have the space to push force straight down and then absorb force and just have this sort of elevator up and down action of energy. Bill: Yeah, there's also an article on Quadruped on the network that breaks it down sequentially and shows the compensatory strategies that would be associated with the failure of that position. Yeah. Chris: Yes. Yeah. And we touched on them. We touched on pretty much all of them, I believe in that episode as well. yeah, the big ones. ⁓ Bill is from Indiana. If anyone hasn't picked that up yet, the big ones. So we talked about the... So we haven't really, we didn't really hit necessarily on the prerequisites of, we just talked about a bit about having enough internal rotation to get into that position. Bill: ⁓ the bigans. Yeah, yeah, yeah, yeah. Bigans. Yeah, yeah, sorry. Correct. Correct. Chris: The, what would you know when someone's walking through the door, you see, you're measuring them on a table, you're watching them say, do a split squat. How would you know that this person's not going to succeed in half kneeling or sorry, in sideline? Bill: ⁓ so we have, we have relative position change as we're, as we're descending into the split squat. Let's, let's, let's focus on the lead leg, especially because that's going to like the descent in the, in the split squat is the acquisition of inter rotation superimposed on the extra rotation. So we start in this big yard space. So like I said before, it's kind like taking a step forward as I descend, I have to be able to. Chris: Mm-hmm. Bill: secure a foot position that can absorb the inter rotation. have to have a tibia that can internally rotate relative to the femur. ⁓ That would also indicate the ability to superimpose IR and then I have a pelvis shape that would be IR. So if I did a perfect split squat ⁓ at the greatest level of descent, it would show that orthogonal IR position. And so if I was going to use that and I saw deviations away from midline of the lead side knee. So that's the expression of the magnification of ER because I do not have the ability to superimpose IR. If I see an anti-orientation or I see the ⁓ lead knee moving towards midline, that's an IR compensation that indicates you have a substitution for the IR. So if I put somebody in a split squat, I see any of these deviations, the acquisition of sideline then could be compromised. Chris: Okay. I think we should talk about what do we do. So say we go, we run the experiment. We're trying to put the person in front of us into sideline. One of the things, all of the things that we mentioned as being visual representations, their perceptual representations of not being able to acquire the position. How do we, how do we work back from that in order to try to transition to like you had mentioned hook line rolling over into, into, so maybe we talk about this space between hook line and sideline that we can use like a three quarters position. Bill: Yeah, okay. you were to gradually, let's go from hook line and we're going to go right sideline, right? So, if I was to gradually move the lower extremity away from midline, move the upper extremity away from midline simultaneously as if to roll to the right, the advantage of ⁓ stopping in the three quarter position is I'm still in that ER bias. Chris: Yeah. Bill: but I can gradually load the internal rotation. So just think about ⁓ just, and this is actually the same sequence of propulsion that we would talk about if somebody was walking, right? I'm always gonna move into that yard space first. I'm gonna slowly descend the center of gravity as I do so, and I'm gonna acquire this internal rotation. So what we can use is we just take a segment of that rolling motion that would end up. in a full sideline position. And so I use this three quarter position. So I use the left side to move me into this yard space to the right. And then I can gradually acquire the inter rotation. So it's just a, it's just like a baby step in between the, the soup pine position and the sideline position. And so we call that a three quarter, three quarter sideline. And again, this slows the process of the acquisition of the IR where I am less likely to have to rely on that compensatory internal rotation or compensatory external rotation because I will gradually acquire the ground contacts that slows the system moving into it. And then that allows me to absorb the energy gradually that I would be using to actually roll into my right side. Chris: Right. And this is, this is a position, this would be a positional consideration as a transition. It's very possible that you try this and it won't work. This is how a lot of this works. We're giving, we're giving concepts. We're speaking conceptually. It's not that it's not a direct try. If sideline doesn't work, three quarters is going to work. That may not be true. What all the other, yeah. And that's what I was going to get into. Yeah. Bill: Yeah. Yes. No, because I still have muscle activity that influences the ability to change. Did I jump on your idea? Chris: Yeah, no, but we can get like if you want to if you want to talk about I was going to mention bony shape change that is has to be required and then the muscle activity that's probably in the way. So we can just mention if you want to just get into those. Bill: Yeah. Yeah. Yeah. Yeah, like, yeah, like, like it use the frame of reference, like some people say, ⁓ I have a right leg that's shorter than my left leg kind of a thing. Right. Well, that's associated, that's associated with the pressure that would be, we'll use the extremity as the example. That would be just a reference that there's more pressure on that extremity than, the other. And this happens naturally as we walk. It's like, we, we, we walk like like shocks and struts, right? So I absorb energy, the system compresses, there's a storage of energy in the connective tissues, bones being connective tissues. So they will yield. And then ⁓ there is a ⁓ elongation that is the energy release. And so if my movement strategy is such that I continuously put more pressure on one side, I will see the compressed shape. Well, that increases the differential. within the bones and it makes it more difficult for us to acquire these ground contacts. And that would be associated with an increase in muscle activity that constrains the shape change that we would normally see. So instead of having this nice little shock-strap behavior, I have compressed, compressed, compressed, compressed. And that again, that's associated with the shape change and that becomes interference to me acquiring these ground contacts. so position, great, useful, but... by running the experiment and saying, what can you do in these circumstances? It also points us in the direction of like, oh, I have too much muscle activity in this area that is constraining the shape that I actually need to acquire the position. And then that targets, like, where do I need to spend time before I do this activity to alleviate that muscle activity, allow the shape change to occur that will allow me to acquire the position. Chris: Right. Cause the ideal scenario would be to choose an activity that is as close to their eventual goal as possible and have that be the answer for whatever compensation you're trying to manage. What the reality, yeah, the reality is you're probably going to have to keep stepping back through these, what most we consider developmentally sequenced activities. So you would go, if you're standing and you're on two feet, you do a split stance, you go to half kneeling, you go to oblique sit, you go to sideline, you go to quadruped, you go to Bill: Right, right. Yeah, we just have to respect where they're starting. Chris: whatever, whatever you need to do. But the thing that I think the step that a lot of people aren't considering or they are, but from a very general and not focused or strategic sense is the muscle activity piece and the bony shape change piece. So people will blindly use foam rollers to try to get muscles to relax, right? And they'll just rub on things in all different directions and hope for the best. you, and sometimes it does, and it's working. I think it's working despite what. Bill: Sure, sure. Well, sometimes it works. Chris: your intentions are in lot of cases. it's the targeted nature and the strategic input of trying to take a bend out of a femur where you're addressing the proximal end of the femur differently from the distal end of the femur. taking that same concept, using that concept on the tibia, like the segment of the lower leg, and then using that concept on the foot. It's being able to understand that. So the best example An indication of that would be like a knee that can't lay flat on the ground when you're in sideline. Or like we had mentioned, the greater trochanter that feels very pointy. Like these are all indications of bones that are twisted and not able to change shape to acquire the sideline position. And what is potentially in the way there is muscle activity of posterior lower hip, of proximal femur, of distal femur. It's VM, VL, ⁓ Bill: Yes. Right. Yes. Chris: any sort of piriformis, gemelli brothers in the posterior lower, like all of these things can be influenced in a specific direction with a specific type of pressure to alleviate, almost take the parking brake off in a way to allow the bones to rotate and move that will let you acquire the position. Bill: Adductor Magnus is a big N. Yeah. Yeah. Correct. Yeah. Yeah, just think about, just think about like, let's just pick on a muscle for a sec. So if I have a concentric line or adductor magnus, so that would actually move my center of gravity over that leg. And then there's, there's our, our downforce through that extremity for me to actually move my, my. lower extremity away from midline to actually capture these contacts. So if I was just rolling over to the right side and I was leading with that right leg, it's like, if I can't move that leg away from midline, the chances of me capturing that contact are slim to none. And so in those circumstances, now if I can reduce the concentric orientation of the muscle and I can start to see that leg now moving away from midline, it's like, well, there's my indication that I have actually... ⁓ influence the shape of the extremity sufficiently that will allow me to capture that ground contact. So we can be very targeted with our use of any kind of manual or mechanical technique. Chris: Yeah, and And that's, there's a presence of mind to a lot of these topics that we're talking about right now because Bill is very deep in the process of writing and creating the programming and interventions courses that will be part of the curriculum of learning this and being certified in this model. So, and that's something that, like I had mentioned is, are things that people, practitioners consider and have always considered, but maybe not in this targeted strategic way. And then in this order, cause it's, Bill: Right. Right. Right. Chris: And the way that we're expressing it, the goal of what Bill has been trying to do is always create this level of coherence between all of these things so that everything is just everything else. And once you address the twist in the foot and the muscle activity there, it's going to be a very similar presentation to what you're looking at in the tibia and the femur and the pelvis and the thorax. And then knowing what's... Yeah, exactly. Yeah. Bill: Right. Yeah. Yeah, yeah, yeah. People don't need to change what they do. They're already doing great stuff. They're already doing great stuff. But we can be a little bit more influential by understanding the representation more clearly because that provides us effective targets for our influence. Chris: Yeah, many of you have the tools already, especially if you're right out of PT school, you have all these tools that you just learned. They're all fresh. It's possible that you could be very effective as soon as you're out of school. Exactly. Bill: ⁓ absolutely. Yeah, yeah. But where and the when, the where and the when is the big challenge because they didn't give you a clear framework of sequencing of level of interference in certain circumstances. So we have to define those circumstances much more clearly so we understand them. And then we say, well, okay, well, what is the influence on this representation? Well, if this is the influence on that representation and it's expressing a limitation in capacity, It's like there is very specific targeting that we can use to provide a more favorable influence. Chris: Yeah, I think that this model learning this model really helps with the where and the when but I one of the most important things I think it helps with the ⁓ shit what do I do now? Like you've tried everything you've used all your tools pulling out everything that you got in your in deep in the bag of tools you got and it's still not working and you're bashing your head into the wall. Bill: Yeah. Yeah, yeah. Yeah. Well, it's when we fail, when we fail and everybody does, I fail, everybody fails. ⁓ But it's not necessarily a failure of the ⁓ technique. It could just be the wrong place at the wrong time. Or not enough. Dosage becomes ⁓ a big deal here, right? Because Chris: or not enough. Yeah. Bill: If you start to see a favorable change ⁓ through whatever you're applying, ⁓ it could just be that you don't need to do the next thing. You just need to do a little bit more of what you just did. Right. But we need a framework that allows us to help make those decisions as to what happened. So I have a presentation I identify, I intervene, I reassess, and I say, well, what happened? And then I can decide based on the outcome of the intervention. It's like, okay, that was good. I need a little bit more of that. And so it's like, so then the next thing you do is I do a little bit more of that. If I continue to get a favorable change, keep doing what you're doing until that favorable change is arrested. Then I need to go to the next intervention. Chris: Yeah. Okay. So I would pose a question to the audience, hoping that some people will comment. If you've ever had someone that you've used sideline with and you still could not manage the position without some sort of compensation coming up, even after intervention, they always seem to revert. Talk about in the comments, let us know what you did and what you tried to do. And maybe if, maybe if this episode helped you maybe. understand why that might have happened, leave us a comment below. And then next time we're going to get into taking this position and then what do we do with it? And then the next possible position might be you go up to an elbow or to an oblique, high oblique sit. And I think that's what we're going to get into on the next episode. So stay tuned for next time.
