hope this time it will work!

Dear Colleagues

I hope you will be willing and able to comment on this one. It's a kind of
follow-up to a discussion started by Richard Baker some time ago.

In my work as a biomechanics advisor/engineer I was asked to review a novel
technology that will enable the measurement of the 3 components of GF Forces
at numerous points on the foot, simultaneously, continuously and accuratelyThe big question is: so what? Is the extra information realy important? The
company claims they can put a 50 sensor insole in a shoe measuring 3d forces
at high speed in a very low cost (300$). Will it help in diagnosing
orthopedic diseases? Will it solve any real clinical or research problem?
Will it help in designing orthotics or prosthetics? And how about a force
plate with 2000 sensors? And if you think it will be helpful is there a
minimal number of sensors needed for practical use?

I want to further focus my question: I am especially interested in actual
clinical research and/or publications on the subject. And if possible not
just in CP and prosthetics/orthotics. I don't remember seeing any such workI know from my own experience and others, like Dr. Davis from the CCF, that
the extra data offered by such a system is very promising but I never saw
an actual work, for example using simulations. I'll be very grateful for any
information on this subject.

Thank you and Happy New Year to all
