So the test is going to be done with the patient's supine.
We're going to apply a very gentle, directed force through the angle of the ilium sacrum
joint.
We're testing the movement of ilium on sacrum.
In the fluid dynamics standpoint, we're testing the slickum in the area.
Remember Neil talked about slickum in his lecture?
What happens if we get sticky, but not sticky?
It's not a good deal.
Sticky equals inflammation.
Slicky good.
Sticky no good.
Right?
So we're looking for a stiff squish test here.
So you have to consider the patient, their sex, their age.
Childbearing females are going to have the steepest angle, about 45 degrees as we put
our palms over the ASIS and slowly glide posterior medial to see how that glides.
And again, this is a very, very slow motion, right?
This is a fluid dynamic structure.
This is a frictionless joint, just like the sacrum, just like the keyloid.
We don't want to have it really fast and shove on, right?
We go up slow, take up the slack, let the pressure gradient change as I move it, and
that's what I'm feeling here.
It's a viscoelastic structure that we're moving here.
I'm just feeling for that joint play to tell me is one side stiff.
The side that is stiff is the side of dysfunction.
Now as we get into the muscle energy phase here coming up after lunch, we'll use that
squish test, but it may change after we correct the pew.
So we'll repeat this a bunch of times.
We don't name anything until we correct the pew.
Then we can start naming stuff, but until we get that midline dysfunction corrected,
we don't know who's really the problem, okay?
So let's just have a body here real quick so you can visually see what this looks like.
So in a male, how stiff would the angle be?
Yes, a child, right?
So you have to take into consideration what the angle is going to be.
Can we finish me?
Yes.
I'll go stand up for a second.
Oh, no.
This thing slides around me.
We're on a slider.
Is that good?
Sure.
I just want to know if you want me to get it from the side or...
Well, I'm just hanging on this side.
I think we're good.
Okay.
Yeah.
All right.
You've got the explanation on there.
Okay.
So again, this is where we've got that stereognosis thing.
Interior spines.
There's one.
There's one.
Okay.
So move the patient towards you and save your back.
Okay.
So I'm going to come in here and get my body lined up here.
And again, one at a time, I'm going to apply a posterior medial gentle force and see if
that ileo-sacral motion moves.
Eleum on sacrum.
Come in here, apply a very gentle motion and say, gee, is that...
It's different as it starts to give.
Again, my motion is posterior medial.
Let it relax.
So the hands are doing slightly different things.
This one's going on that angle.
And this hand is going on...
Not about that angle.
Very gently.
You're just engaging it.
Because remember, there's fluid between the ileum and the sacrum sitting here.
So you're trying to see if you can bump them into each other.
If they're stuck together, there won't be nowhere to go with it.
But you have to go slowly because if you pounce on any joint in the body, it will stiffen.
It's job.
So you have to go really slowly to feel the bump.
Okay.
Is the fluid compressible?
No.
That's what we've got here, right?
But there is motion here.
I just have to go slow, not overcome the resistance.
If I come in here and just jam on it like that, I'm not a clue what that just did.
It's going to make that side pop up, but that's what's going to happen.
If I move fast and jerky, that's going to jam it.
It's a false test.
So I compare one side to the other.
My elbow out here.
There's my oblique force coming in here to posterior, posterior medial.
Get on it.
I'm right here.
Pump.
Glide it back, see what it does, and then compare left to right.
Okay?
See, push one and then hit the other.
Yeah.
Yeah.
Compare the glide on one side, let it release.
Compare the glide on the other side, let it release.
Do you not have any counter-pressure on the other hand?
Nope.
Because if I did, I would disqualify the test.
Because if I get over and I start pushing, it's not moving.
It's pushing, but it's not moving.
What's going to happen over here?
It's going to raise up.
That's my stiff side.
So we're looking at that quality of slick on one side compared to the other.
So we'll come around and put our hands on your hands so you can feel how much pressure
is really needed to do this.
Not a lot.
Very little.
Okay?
Now what?
Nothing's right up there.
