In-Shoe Pressure Measurement and Foot Orthosis Research: A Giant Leap
Forward or a Step Too Far?

Simon K. Spooner, David K. Smith, and Kevin A. Kirby
J Am Podiatr Med Assoc 2010;100 518-529
Quote:
Foot orthoses are believed to exert their therapeutic effect on the human locomotor apparatus by altering the location, magnitude, and temporal patterns of ground reaction forces acting on the plantar foot during weightbearing activities. In-shoe pressure-measurement systems are increasingly being used by clinicians and researchers to assess kinetic changes at the foot-orthosis interface to better understand the function of foot orthoses and to derive more efficacious treatments for many painful foot and lower-extremity abnormalities. This article explores how the inherent three-dimensional surface topography and load-deformation characteristics of foot orthoses may challenge the validity, reliability, and clinical usefulness of the data obtained from in-shoe pressure-measurement systems in the context of foot orthotic therapy and research. The inability of in-shoe pressure-measurement systems to measure shearing forces beneath the foot, the required bending of the flat two-dimensional sensor insole to fit the pressure insole to the three-dimensional curves of the orthosis, the subsequent unbending of the sensor insole to display it on a computer monitor, and variations in the load-deformation characteristics of orthoses are all sources of potential error in examination of the kinetic effects of foot orthoses. Consequently, caution is required when interpreting the results of orthotic research that has used in-shoe pressure insole technology. The limitations of the technology should also be given due respect when in-shoe pressure measurement is used to make clinical decisions and prescribe custom foot orthoses for patients

Look forward to it. This paper was spawned by the Arena.

Not sure if this is normally the done thing but Congrats to you three,Simon, Dave and Kevin.

I learnt more about vectors reading this in a single read than most of my reading combined or things became much much clearer which ever way I look at.

Not that my option counts for much, but anyone wanting to understand more about GRF Vectors it´s a must read.

As well as asking some questions which I´m sure will be discussed a lot.

Thanks, Mike. Any questions ask away... I'd also like to take this opportunity to thank my co-conspirators: Dave and Kevin for their time and effort in taking this paper from the germ of an idea into the publication it became. We just need to lean on Smith so that we eventually get the follow-up written.

Good morning all, the difference between "force impulse", which is the 'integral of force with respect to time' and "force integral", p.519, 3rd line

Congratulations to David Smith for what I believe is his first published paper in a peer-reviewed podiatric publication. Good job Dave!!

Looking forward to co-authoring many more papers/publications with Dr. Spooner in the future.

I have uploaded the paper for those who want to have a look at it on my private website. http://www.box.net/shared/z9vvdj6lt8

You may e-mail me privately for the password.

1st Question Why did you not introduce the term Orthotic Reaction Force (ORF )into the discussion.

There will be more but as I was reading the 1st 2 pages

I was expecting something like - The authors believe that once an orthoses has been introduced and eccepted that Bower´s (2)definition of how an orthoses works - GRF´s are modified point of application and line of action of GRF´s, this reaction force should be referred to as an Orthotic reaction force.

The reason I ask is because I usually refer to ORF´s would it be better not to ?

More Questions to come about direction of GRF.

thanks, mark
Yep that was eagle eyed of you Mark!!

Remembering that it was quite a whil,e over a year ago I think, that we finished that paper, I wrote that bit but I can't explain that odd one off the top of my head so I'll put it down to a missed typo, e.g. I might have meant 'impulse or integral' meaning either depending on which term you prefer or I might have meant 'force impulse and pressure integral' so that it read better than repeating impulse. I could look back at some drafts and see if that gives a clue, if I still have them.

Here is a link to an excellent explanation of the principles of integration of force impulse and momentum http://spiff.rit.edu/classes/phys311...e/impulse.html

Many thanks to Simon for forcing me to write the paper and to Kevin for his input and encouragement. I do have some half done papers and a couple that need formatting so I'll try and find the time to get to them or even write something new.
You never know I might have 2 papers published before my 80th birthday.

Regards Dave Smith

Thanks Messrs Spooner, Smith, and Kirby, read it 2 1/2 times if you average out how many times i read each sentence.
The first 3 pages should be compulsory reading for all podiatrists.
I was getting all depressed but, like an American movie, the ending gave me hope, mark




One day I'd like a paragraph in an article in a peer reviewed journal to begin, "Conley ........"
