Dr. Simon Spooner just had an excellent article published in Podiatry Today Magazine on 3D Orthoses. I highly recommend it.

Good job Simon!

For the record, the pictures accompanying the article have nothing to do with me. If that's a Root orthosis you can call me Simon Van Spooner.

This headline caught my attention need to read the article later

And on a personal note, myself and others have been fighting that battle for the best part of two decades with regard to podiatric biomechanics... and are still banging into those defending the status quo with all their might (though less frequently now). Give it a couple of decades...
One of the other issues is that quite often the technology is in the wrong hands, i.e., those trying to make a quick buck, rather than with the deep thinkers and the knowledgeable with regard to foot orthoses in the clinical sense. Viz. a product comes to market that has no advantage over the existing technology, just manufactured in a different way.
For example, I got into a "discussion" on twitter last week when the article was published with someone promoting their business that is selling 3D printed foot orthoses. He claimed 3D printing was "a game changer" for the industry, I asked "in what way?". This is the response I got: "Durability, accuracy, mass customization, intrinsically change flexibility/torsion with one single material using geom. structures". Hmmm, questionable marketing response- I'm sure you'll all agree. Moreover these are the first things on your patient's mind when discussing their treatment options- not.
But when pressed, he admitted that at present 3D printing of foot orthoses was slower, more expensive and no more efficacious than existing manufacturing processes- I'm guessing that at least two of these factors are important to your patients.
So... I got bored of the marketing speak at that point and asked how they'd design a foot orthoses for an 18 stone professional rugby play with a mid-portion plantar fascial tear. Strangely enough, I got no response...

Simon,
Appreciate the insight and review of the technology, as this stands. Given the current limitations, where should technology be going, now? How can the technology best address design and manufacture issues to improve on the 3-D technology of today? Is there a future for integrating technologies e.g. F-scan analysis / Video Kinematic Studies etc. I am trying to figure out, I guess: what's your ideal vision & set up? -
I read an edition of JAPMA from 1960 today, in which there was an article where the author stated something like: "if you ask people what causes foot problems, people will answer "fallen arches" but anyone will tell of any number of individuals with the flatest of feet, yet who suffer from no problems"- something like that. Technology in terms of measuring things is great- we can measure 3D kinematics, 3D kinetics, but if we don't know what the significance of those measurements are to the patient in front of us... we might as well be talking in terms of "fallen arches" and using a Harris-Beath mat.Last edited: Dec 6, 2016 -

btw ... Kevin endorsed the concept of 'foot typing' a la Drs Scherer et al ( that's what Dennis stole first) -
-
Well, ok - lol it's a written record of fact that he did. Since Kevin carries a lot of gravitas in the field I don't dismiss this as lightly as you. I was always curious to know why Dr. Scherer abandoned the idea in favor of pathology specific orthosis. I will call him one day, to get the low down.
As for the reference, sorry no can do. All that material was trashed when I jumped across the Atlantic. -
And 30 seconds on the Google machine and you can find what you need ;-)

lol ... ok, grumpy pants. I can tell you're not interested. I was always curious to know if a similar foot-type might behave in a predictable pattern. Perhaps to know, for sure, we'd need the assessment tools we don't yet have. So: whatever, dude.
-
a) I'm not your "dude" b) you'll always be that funny little man, with ideas above his station trying to gain his degree in podiatry to me. :) Wind your neck in fella, and we might get somewhere.

lol ...too funny, dude. I got several Podiatry degrees 'above my station' but thanks for caring.

I don't know where you got the idea that I ever endorsed "foot typing" as per Paul Scherer and Jack Morris chapter in Ron Valmassy's book (Scherer PR, Morris JL. The Classification of Human Foot Types, Abnormal Foot Function, and Pathology. In: Valmassy RL. Clinical Biomechanics of the Lower Extremities. St. Louis: Mosby; 1996. p. 85-93).
Yes, both Dr. Scherer and Dr. Morris were professors of mine during my Biomechanics Fellowship, and yes, I also wrote a chapter, titled "Troubleshooting Orthoses", in Valmassy's book. However, Scherer and Morris's chapter and foot classification, which I was not aware of until it was first published 20 years ago, was in the exact opposite direction to what I was working toward at the time.
I have never endorsed Scherer and Morris's foot classification scheme either 20 years ago or at any time over the past two decades. I read it, I understood it, but don't like any concept that "pidgeon-holes" foot biomechanics for simplicity. I believe this type of "foot typing" approach leads to crude generalizations that aren't always true and relies on only externally measurable variables that are often not functionally significant.
In addition, I don't endorse Dr. Shavelson's foot classification scheme either, and never had.
Please, Dieter, or anyone else, before you claim I have endorsed or not endorsed a concept, check with me first.-

Sorry, but you did. I believe it was for the book review published in a magazine. If you really need it I can probably dig ot out sometime. Right now I don't have access to my library. -
Ya,

Good luck Dieter love. For the record: neither your "buddy" nor your "dude". Funny thing is, you'll always be "Dieter love" because the league of gentlemen said so... and that baseball cap just makes it more so. Bless your cotton gusset. You are not American, don't try to pretend to be.

Eric Fuller and I were, and still are, as they say, kindred spirits. Our collaboration over the years resulted, ultimately, in our chapter on Tissue Stress Theory that was published 3 years ago but was completely written 10 years ago (Fuller EA, Kirby KA: Subtalar joint equilibrium and tissue stress approach to biomechanical therapy of the foot and lower extremity. In Albert SF, Curran SA (eds): Biomechanics of the Lower Extremity: Theory and Practice, Volume 1. Bipedmed, LLC, Denver, 2013, pp. 205-264). I don't believe either of us like the idea of "foot classification" as proposed by Scherer and Morris or by Shavelson.
I believe you may want to speak to Eric Fuller about the origins of the term "pathology specific orthoses". He has an interesting story to tell about that one also. -

However, I might have said in one of my thousands of online comments over the past two decades on the various podiatry websites that I thought that my biomechanics professors' foot classification system may be helpful for some podiatrists. I really wouldn't call that an endorsement but rather an acknowledgement that some clinicians, those with a relatively poor knowledge of foot biomechanics and a relatively poor potential for further improvement in their knowledge, may be helped by anything that makes the complex topic of foot and lower extremity biomechanics more simple for them.
