Good morning. Happy Monday. I have neural coffee in hand and it is perfect. All right. Quick housekeeping item. Applications for the Intensive 17 are still open but they will be closing this evening. So if you've been waiting or you've been thoughtfully filling out your responses, please do so in a timely manner because we're going to close this down this evening. We have to get started on the blind reads of the applications to select our eight people by, I believe, Friday. So we'll get that done for you. But again, please be timely with your applications. Digging into today's Q&A, this was Zach. Zach was on a coffee and coaches conference call last week and he actually brought a case to the call. And we actually have a representation of this where we're talking through someone's representation of where their center of gravity is based on a static standing representation. Does this give us all of our information that we need? Absolutely not. But it does provide us indications. It does provide us clues. And then we have to correlate these things with if we do table tasks or if we do dynamic movements. We want to make sure that we correlate that. But there's a lot of information that you can glean from someone's position in space. And so we kind of break that down. So this would be very useful for many of you who might be in an environment where you don't do table tests, and you have to rely on some visual representation. So thank you, Zach, for bringing this. If you'd like to participate in a 15-minute consultation, please go to AskBillHartman at gmail.com. AskBillHartman at gmail.com. Please put '15-minute consultation' in the subject line so I don't delete it. Include your question in the email if you will. We'll arrange that at our mutual convenience. Everybody have an outstanding Monday. Happy intensive week. Intensive starts this Thursday and we will see you tomorrow.

SPEAKER_06 1:57–2:52
So first question is about getting an idea of where he is in space. Some of the most limited measures I've taken to date are about five to 10 degrees of hip internal rotation bilaterally. The right shoulder was five degrees of internal rotation. Even his external rotation was less than 80 degrees on either shoulder. The hip external rotations were up around 50 on the right and 40 on the left. Shoulder flexion was below 50, at 45 on both sides. The first question that came to mind is that as a narrow, he would go forward on the left first and then start to head right, with the right side getting pulled down. I feel like I've seen you have his feet in the picture. I don't have his feet.

Hang on a second. Can you blow that up?
SPEAKER_06 2:58–2:59
Where do you want?
SPEAKER_03 3:00–3:10
Slide down so I can get as close to his feet as possible because you can kind of see where his ankles are. Ah, there we go. Awesome. Perfect. Okay. Golden.

So like getting pushed to the right and that right side's turning out.

SPEAKER_03 3:17–3:39
Socket it okay, so go back up to the shoulder for a second. It's like blown out with everything. Yeah, just slide up now. You're fine. What did he do with this pet monkey? You know the pet monkey that he had hanging on his left shoulder when he walked in the door. What did he do? Did he set it down or something?

SPEAKER_03 3:47–3:53
OK. So what direction is the right glenoid pointing?

SPEAKER_06 3:53–4:01
The right glenoid would be pointing outwards, like into more of an ER orientation.

SPEAKER_03 4:01–4:11
Up. ER is up. Right. So, it's up and out. Would you agree? Yes. Okay. What way do you think his right acetabulum face?

SPEAKER_05 4:13–4:13
Same thing.
SPEAKER_03 4:14–4:39
Exactly. The same thing. So he has a massive amount of orientation here. This is, and you can see it, and he's got the perfect shirt on, cool logo and all, but you see the draping of the shirt is telling you where his anchor is and then what direction he is literally moving to the greatest degree.

SPEAKER_06 4:39–4:42
Can you elaborate what you mean by like the anchor?

SPEAKER_03 4:43–5:27
Okay, so you see his left wrist is holding his shirt down, and then he is pulling his shirt in the opposite direction. You see the draping? Yes. So he's kind of pinning his arm against his left hip, right? Because his monkey pulled it down before he got into the room. You see it? You see how everything's just moving up into the right? Yes. Yeah. So he bumped into, he literally bumped into his hip and he had to turn it up and out to keep moving to the right. Gotcha. So I guess in the old school, they would say, man, he's got a really long left leg.

SPEAKER_01 5:32–5:32
Right?
SPEAKER_06 5:33–6:07
Yeah. So I feel like with narrows, I have seen people with less limited range of motion, but it looks like they've started to get pulled down on the right, which up until now, my interpretation was kind of like those two things would be directly correlated. And like the more limited your range of motion gets, the further you've gone along, the right side should get pulled down. Super limited, but it doesn't look like that right side's getting pulled down as hard as some people I've seen in the past. So I'm thinking there's some sort of mismatch in the way I'm thinking about that.

SPEAKER_03 6:08–6:14
Okay. Why would you get pulled down? What would be the reasoning behind getting pulled down?

Just like the concentric orientation and the right posterior lower now.

SPEAKER_03 6:22–6:30
No, no, no, no. Not a description of how. What I want to know is why would you even use that as a strategy?

I guess I'm not sure why this might happen, but I'm thinking like, if the right.

Hang on. So let's follow his shirt. Let's just keep shoving him to the right.

SPEAKER_06 6:46–6:55
So that's kind of what I was thinking. Like if he's continuing to go up into the right, like eventually he needs to get that foot back and that leg back to the ground just to put force into the ground.

SPEAKER_03 6:56–6:59
He can only turn his leg out so far before he runs out of strategy here.

So is the down in IR orientation?

SPEAKER_03 7:06–7:33
The down is the IR, right? He's going to figure out a way to go down, right? So I can anteriorly orient, but I only have so much of that. I can side bend, you know, by traditional terminology, but I only have so much of that, right? Eventually I have to pull back down to stay inside of my base of support, right? Is he doing that yet?
