Plantar Pressure analysis

[Zahra Safaeepour]

Hi every body,
We are collecting plantar pressure Data with Inshoe plantar measurement system(NOVEL). Walk way is about 8 meters and according to the data procedure, at least three trials is acceptable . does any body know if each trial should be done separatedly or we can collect data continiously.
In case of separeted trials , should sensors be recalibrated for each trial?
Thank you

Re: Plantar Pressure analysis

Zahra, the suggestion to collect 3 to 5 repeated trials applies to the barefoot measurements when walking over the pressure distribution platform. For in-shoe measurements, you should collect something like (or at least) 10 steps in one trial or several trials, depending on your walkway length (and subjects' step length). If you don't change the shoe condition, i.e. tighten the shoe strings or anything like that, then you would not have to recalibrate (i.e. 'zero') between trials.
I hope this helps. Good luck/success,
Dieter...

Hi
Thank you for useful remarks,
As the walk way is not long enough then we have to collect data in three trials (3 steps per each trial),
Thank you for recalibration hint, I was so confused with it.
My other question is about computing COP using plantar pressure inshoe. Novel software gives 2 components of COF(x,y), but I dont know how to report it?
-can I report it as COP(x,y)?

Re: Plantar Pressure analysis

Hi,

I have a similar question. Have you got to solve calculating COP(x,y) from the COF(x,y) data? The plantar pressure system that we use in the experiments gives COF but not COP. Greatly appreciate if you could share any hint..
