Not going to be here for ever, so I wanted to start listing these:
Members do not see these Ads. Sign Up.
Tick boxes on the "prescription forms" that labs provide which state something along the lines of: shell material- flexible; semi-flexible; rigid.
Cobblers, trouser-taters and a bit more bollox. Meaningless none-sense. Unfortunately, the tail has been allowed to wag the dog for too long here.
"arch fill"? Minimal; Moderate; Maximal? - you got to be kidding me.
And obviously: "Lab's discretion".

Many of my customers fill nothing out and simply write "Steven, call me".

On top of my list are people that have closed and locked their small minds with their rigid beliefs whether it be biomechanics or any other subject.
Building a belief system is akin to building a sand castle on the beach. Sand can be added or removed just as knowledge to a particular belief can be added or discarded.
The sand castle is open to change; change for the better, change based on the evidence of the current time.
It is when the sand castle is built not with sand but with bricks and mortar does it stay resistant to change. Its fortified walls prevent new ideas from coming within so the old ideas within the castle can be safe and protected.
I like what Craig Payne writes frequently, "I go where the evidence takes me". It is that kind of thinking that allows us to always continue to build and reshape our sand castles.

When a client asks for an identical pair of orthotics to their 10yr old ones that have worn down and no longer represent any known device. hahahaha.
God love the Lab that dealt with the returns and adaptations! They were so patient. -
Steven,
Isn't there something between these two dichotomies. The important thing is to be flexible, but not easily blown over with the latest "evidence." Evidence is cumulative, and of course it is important that one consider whether the new evidence really negates the old evidence. That is why the most important part of any article is the methodology section. And of course it is important that the reader not accept the conclusions that the author has made, but instead really analyze the data presented to see if they come up with the same conclusion.
An important example is all the discussion about the movement of the MTJ, and how many axes there are. Much of the discussion on this forum has been more like the seven blind men discovering what the elephant is and making their models. Yes the elephant can be modeled as a spear, but it can also be modeled as a snake, a tree-trunk, etc. Everyone takes their favorite researcher or author and then builds their little castle around that author and protects it from attack, instead of trying to see if the two castles can be merged into a larger castle that can hold all the evidence, and with the realization that there is more evidence to come.
While Simon may be correct in his lamentation about the quality scale of arch fill tick boxes, as well as other tick boxes, he himself also creates a gap in that he rarely tries to make quantitative clinical measurements. So without quantitative clinical measurements, how does he expect to fill in a quantitative lab order form. He's got to start becoming part of the quanitative clinical and laboratory solution, not just keep throwing rocks at the old guard.
As you remember from the 'old' days at CCPM, all students were taught to make their own orthotics. Such is a rare bird today, to find a clinician who makes his/her patient's orthotics themselves. However, if you really want to learn orthotic prescription techniques (note I did not say learn biomechanics because biomechanics is a lot more than just make inserts for shoes), then make the orthotics yourselves, and welcome every opportunity you get to fix a pair of orthotics as another learning experience.

My favorite Ad (from Apple):
“Here's to the crazy ones. The misfits. The rebels. The troublemakers. The round pegs in the square holes. The ones who see things differently. They're not fond of rules. And they have no respect for the status quo. You can quote them, disagree with them, glorify or vilify them. About the only thing you can't do is ignore them. Because they change things. They push the human race forward. And while some may see them as the crazy ones, we see genius. Because the people who are crazy enough to think they can change the world, are the ones who do.”

Hi Simon,
I am at the moment working on designing a prescription form with my partner.
Would prefer if labs stated the specific material grades that were flexible, semi flexible, or rigid?
alternatively,
As I understand many podiatrists prefer to distinguish variously rigid grades of polypropylene and Eva by their colour instead of their specific material number or trade name.
kind regards,
Dean -

Simon, you're missing your opportunity to "quantify" your Rx -

Things that annoy me, part 2: people attempting to flog their dead horses on Podiatry Arena. Stop spamming these pages with your junk Dennis Kiper.
No dead horses here and certainly not junk. Science based technology predicated on principles of physics. You should take some science classes Simon Spooner or maybe you're trying to come up with a new model for foot orthoses based on more NON-SCIENTIFIC TECHNOLOGY. -

Thanks Simon,
I assume you will know this but just for anyone else who does not, the reason the high arches will be more rigid than the low arches is because of the :
"increased area polar moment of inertia that a high arc has over low arch."
furthermore it is important to note that as a person chooses a different cross section of a known arch shape to determine rigidity about, they will get a different rigidity due to the different polar moment of inertia of that cross section.
This effectively makes net rigidity very difficult to calculate unless you use finite element analysis.
I suspect the overwhelming majority of podiatrists depend on rules of thumb to determine the designs for their patients' orthosis.
As for the thickness, many modern orthotic fabrication process allow for varying thicknesses of material throughout the orthotic. The exact material thickness can be specified by the podiatrist or may vary along the cross section.
Would the best solution be to provide a supplementary datasheet that could be downloaded which quantifies properties of the materials to be selected by the check boxes?
Best regards,

We also have four levels of medial arch fill: minimal, decreased, standard, increased. Customers know from experience how these relative levels of fill will influence the shape of their orthoses. It is important to educate customers and for them to ask for advice if they aren't clear on lab standards and options. It doesn't take too long to gain practical knowledge in orthotic Rx writing.
