The Windlass Mechanism


hey team how you doing this video I’m gonna look at feet particularly a mechanism of the foot called the windows mechanism now this is a really important mechanism of the foot and if you’re a bit grossed out by feet as some people are stick with this because there’s loads of important information here in fact this is the first of a number of Q&A videos that I’m going to be doing as a result of a few comments on Facebook comments on YouTube where people have asked me to elaborate in what I’ve already said about the windlass mechanism in previous posts previous videos where I’ve just kind of mentioned it in passing this time we’re going to get right into it so let’s have a look so let’s deal with a big question first what is the windlass mechanism so the windlass mechanism is a function of the foot which allows it to be everything from a very adaptive structure with lots of movement allowing us to adapt to landing on different surfaces and have that ability to dissipate load nicely

Vitamin D


hi everybody dr mike here in this video i want to take a look at vitamin d [Music] so remember vitamin d is one of the four fat-soluble vitamins d e k and a and a vitamin is a nutrient that we require in very small amounts that we cannot produce ourself but we need it for normal growth and development vitamin d being a fat soluble vitamin what that means is it can be stored within our body because the cells of our body are surrounded by fatty layers and it allows for the movement of this vitamin into those cells easily and therefore easy to be stored water-soluble vitamins however they often get excreted from the body quite quickly that’s one of the major differences so when we look at vitamin d first thing you need to be aware of is that the main way that we get vitamin d is through uv exposure or our exposure to sunlight so this is going to be the first step

The MOSI Archies


Hi everyone craig payne here i just want to talk to you about a little trick that i’ve developed with these things. These are the Archie’s thongs. Now we call these thongs in Australia, jandals in new zealand and flip-flops in the rest of the world, but these come with an arch support built into them and we sell them like hot cakes in the clinic pretty much everyone who tries them on likes them. The problem is with any arch support or any or even in these or in the orthotic. If that arch support pushes right where the subtalar joint axis happens to be that they can actually be uncomfortable or even worse, if the subtotal joint axis is very medial, the actual arch support area is on the lateral side of that joint axis and there’s actually a Pronatory moment at the subtalar joint, so that’s not exactly a desirable thing.

PodChatLive Episode 92 with Doug Richie [The Richie Brace]

Uh welcome everyone and uh. Thank you for joining us if you’re joining us live or what you’re listening after the fact, um we’re here on 29th of april 2021, recording episode, 92 of podca live and we’re super excited that uh dr doug richie, has joined us thanks for joining us, doug uh.

The abductory twist


Abductory twist. The abductory twist is the rapid media movement of the heel at the time of heel off if there are increased pronation moments occurring during the time of late mid stance this will prevent the subtalar joint from supinating as rapidly as it needs to and therefore also prevent the tibia from externally rotating as fast as it should. When combined with the pelvis which is externally rotating about the latest stance foot will create an increase in elastic strain energy within the transverse plane which will then be resolved into this abductory twist motion of the heel whipping medially at the time of heel off due to the frictional friction from the heel being suddenly released at the time of heel off here we see the abductory twist occurring in the left foot at the time there and this is caused by this combination of late midsstance pronation moments in combination with the transverse plane movements of the pelvis about the foot.
