  • 3D GF forces - are they actually useful?

    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
