So if I have an arrow on the table, okay? Arrow on the table, the early Hippie R drops off, but late Hippie R might be magnified. So this is why you have to distinguish between the early and the late representation. So we're, and I know you know the answer to this because I remember you answered it on a video previously. If I compress the posterior aspect of the pelvis, where does the ER go?

The posterior aspect, you said?

I compressed the posterior aspect of the left side of the pelvis. Where does the ER go?

Away from the leg.

So what ER measure am I going to lose on the left side in a narrow ISA?

I guess early, but I'm just trying to see the difference.

That is the correct guess. Okay.

So what would be the difference with the white? Narrow and white on that left side?

So what are they going to maintain? What is the wide going to maintain because of the pelvic positions are different?

Yeah.

Okay. So what is it? What are they going to maintain?

We're talking about the left side, right?

Talking about the left side, correct. I think you... Early hip ER is one of the distinguishing characteristics that will help you clarify what you're looking at in regards to an archetype.

Okay.

The early hip ER drops off faster on the left in a narrow stance. It drops off faster on the right with a wide, early stance. So this is in front of the body. This is the ER measurement in front of the body. Your hip reduction measure is a late yard measure, right? So if I have an arrow on the table, first move, early hip ER drops off, but late hip ER might be magnified.

Yeah, yeah, yeah.

Reduction measure. Okay. Is a late hip ER measure, right? So if I have an arrow on the table, okay, arrow on the table, first move, early hip ER drops off, but late hip ER might be magnified.

Yes. Okay. I was confused because I was thinking about the turn of the spine, the lumbar spine, on the right. That's what got me because I was thinking technically. So the narrow would maintain its ER, while the wide would lose it. But no, I think I get it now. I have to think a little more about it, but I think I get it now.

You have to appreciate the orientation of the pelvis when they make that first move of the center of gravity.

You mean the flat and the oblique one?

Do you have a pelvis in front of you?

No, no, but I can visualize it.

Excellent. Okay. If I bring the Ilium closer to the femur, can you appreciate the fact that there's a change in muscle orientation?

Yeah.

Can you, so like just by bending the hip, Ilium closer to the femur, can you appreciate the fact that there's a change in muscle orientation?

Yes.

So, if you look at the fan-shaped representation that they always do of the gluteus medius, then as the hip moves, there's more of the gluteus medius that becomes an internal rotator of the femur.

Yeah.

Right. If that's the case, then I have to lose extra rotation.

Yeah. Okay.
