Hi all

I'm looking for an article published in 1992 JAPMA Vol 82, issue 1 by Phillips and Lidtke.

Can anyone provide me with a PDF?

Thanks in advance

Was that their paper on identifying the 3 dimensional orientation of the STJ axis? I don't have the paper any more, but back in around 1994 myself and a colleague developed some software to solve all the equations- it ran in DOS, and with the processing power back then took about 10 minutes to solve.

P.S. there was an error in one of their equations, but I can't recall which one. Maybe you'll spot it for yourself. The bigger problem was that their system required lots of goniometric measurements, with lots of error for each one, I abandoned it for my PhD as it was just too time consuming.

 

I guess so! I was just going through some older powerpoints and found this one. Haven't read it, but was wondering what they did.
Thanks already for the info! I can imagine things changed since then...

cheers

If memory serves, they basically set up a Cartesian co-ordinate system on the foot using skin markings and then looked at the displacement of a number of bisections relative to the co-ordinate system as the STJ was put through planal movements. There were two papers in the series (the first was by Phillips and Phillips- I think), the first paper lacked the transverse plane projection, the second paper by Daryl and Roy incorporated Kirby's technique to include transverse plane. The skin movement was a real pain as the co-ordinate system distorted. Daryl did develop a measuring instrument which was quite a useful tool for the purposes, but I never owned one and had to make do with various size trachtographs. If only I could have grown the extra hands required to manipulate the foot and take the measurements at the same time!
