Correct. Yeah. So, when you think about the anterior orientation. Okay. So let's just look at the pelvis for a sec. You've got five segments in the lumbar spine. Fair? Yeah. Okay. It doesn't all orient to the same degree at the same time. It's sequential. So if we're a wide ISA with anti-orientation, it goes pelvis, L5, L4, L3, L2, L1 in that sequence. The greater the degree of compression, the greater the degree of anti-orientation, the sequential loss of spine motion will occur as well. So when you have somebody that has like one of those magnified measures, it's like 45 degrees of hip IR. Okay, that's a lot, right? That's somebody that still has a spine that can move in some of those segments. When you have the reduction of both ER and IR, which is a lot of anterior, posterior compression, a lot of anti-orientation, all of that spine motion starts to disappear. This is where you get the people that come in and you measure them and they're like 20, 10, like 20 ER, 10 IR kind of thing. Do you understand?
