Good morning. Happy Monday. I have neuro coffee in hand and it is perfect. All right. Had a pretty good weekend. Actually revamped the office a little bit. Rewire nice things, got it kind of looking the way I want it to look. Almost, almost getting there. So I feel pretty good about things. I'm going to dig straight into today's Q&A. This is with Alex. So Alex's question pertains to some shape change concepts. And so it started with the foot. When we talk about different shape changes, we talk about pelvis, we talk about thorax and things, but can we apply the same concepts to the foot? And the reality is, yes, we can. In fact, there are already mobilizations and manipulations and such that are actually quite effective. I think that what was lacking in regards to the explanation and the reasoning in the past is that there just wasn't an effective model upon which we could base our thought processes and come up with a logical and reasonable presentation as to when these things are most effective. And I think once we do that with an effective model, then we become much more influential with our application of manual therapies. And so that's kind of the direction that we went here. We were looking at some examples as to how we would actually apply this and like in what context we would apply this for the most effective result. So thank you Alex for asking a great question that's going to help a lot of people. Everybody have an outstanding Monday and I will see you tomorrow. All right Alex, thank you for your patience.

Good morning. Greetings. In the same way that you can lie on the side, push on their pelvis and roll them forward and back to get AP expansion, I figured it's relatively easy if you're holding someone's foot to do something similar - just apply pressure in such a way as they move that you would get the AP expansion in the foot. I'm just not sure what it is. Perhaps you've covered this already.

Oh, wait a minute. So hang on. So you're trying to use a foot to create AP in the pelvis?

No, sorry. Literally just like AP expansion in the foot with my hands.

Applying.

Yes.

Yes. That's my question. I would agree.

I would agree too. I just don't know what it is.

Okay. So where would you have this anterior posterior expansion in the pelvis at what point in a propulsive phase would you expect to have the greatest AP expansion?

Early. So what does an early foot look like? I mean, a plantar-flexed, first ray, sort of Taylor position. Let me grab the foot. So yeah. See the groove made to put your thumb right there? You've ever done a cuboid on a foot? Same position.

So it's going to look like that, correct? All right, so I can take the foot and turn it like this so that I'm looking at the bottom of the foot.

You see the groove? That was made to put your thumb right there. See it? You ever do a cuboid on a foot? Yeah, same position.

Yep, that's what it is.

It's like a cuboid position.

So you can do the cuboid whip. Could you also, I mean, I assume you can also just apply some pressure. Tell them to breathe it out.

Absolutely.

Tell them to breathe it out.

Yep. Absolutely. You can. Absolutely.

You can do bias or pressure to the entire foot.

I'm trying to create a shape. So it's like, where do I have to put the pressure to create the shape that I want, right?

So that, in that situation, you're like, burritoing it.

Yes. So you're creating an ER shape. You don't want a flattened representation of a mid-foot. You have to create the curve. You're going to close those spaces in. You have an axis of rotation in the fifth ray and an axis of rotation in the first ray. Then you're going to close that space together. The thumb fits in there. Then it's just a matter of being coherent with extremity position to allow the ER shape.

So I mean, what I potentially get a greater benefit if I'm just trying to create like the AP expansion of getting them to like lie on that same side hip on their side, just like literally have them be in that position.

To get the AP? Yes. Potentially, yes. Or could I hold that foot position and, like, tug on their leg and guide them into a roll?

Would that be of any benefit?

You had me at tug on that leg, actually.

Stop there?

Well, I didn't say stop there, but you had me there because that's actually one of the all-time great strategies that is underappreciated. If you do it on the correct leg at the correct time. Okay, that's the question. Did they teach you how to pull on somebody's leg in school? You cut out for a second. I missed the great answer. I'm going to restate the question. They taught you how to pull on somebody's leg?

Yes.

When did they say to do it? What's the presentation? What's the presentation with that technique is successful?
