  • Joint Motion Device

    Hello Bio-Netters:

    First of all, I have changed positions from Baylor College of Medicine in
    Houston to Baylor Univerity Medical Center in Dallas. My new address, phone
    numbers and e-mail are listed below.

    Secondly, is anyone aware of a comercial device which will measure the six
    degrees-of-freedom of a joint. For example the knee joint. Is there a
    product that you can strap across the knee and it give you the 3 axes of
    rotation and the translationx about those axes, simultaneously. I am talking
    about for live humans during various activities (walking, stair climbing,
    jogging, etc.) I am aware of the 3-D magnetic trackers and the instrumented
    spatial likage devices. But software needs to be written to make the
    rotations and translations make sense for the jont coordinate system. Before
    I waste my time writing the software for one of these 3-dimensional systems,
    I want to make sure that there is nothing already out there which is
    comercially available.

    Thank you and Seasons Greetings!!!!!!!!!!!!!!!!!!!!
