  • Motion Analysis on the Mac

    Dear BIOMCH-L readers:

    We are starting a new orthopaedic biomechanics research laboratory at San
    Francisco General Hospital. One equipment item we are considering to purchase is

    a cinegraphic motion analysis system for either 2-D or 3-D studies. I wanted to
    ask BIOMCH readers two questions related to this:

    1) do you know of any motion analysis systems which can be hooked up to a
    Macintosh computer (with a PowerPC chip and National Instruments A/D board)
    for data acquisition and control? The only one I have heard of is from a
    company called MacReflex. Do any BIOMCH readers have experience with this

    2) how many cameras are required for acquisition of 3-D kinematics? I have
    heard responses which vary from four cameras to more than six.

    I will post all responses. Thanks.
