  • need telemetered footswitch system

    Fellow biomech-l folks:

    A colleague wants to measure foot switch or ankle goniometric data during
    walking. She is looking for onset of fatigue, and is looking for 'foot drop'
    - either as a change in ankle angle (if using goniometry) or as a change in
    the timing between initial contact and foot flat (if using foot switches).
    She does NOT want to use a treadmill - thus, the system needs to be untethered
    (either telemetered or collect for a time, then download data). She needs to
    be able to collect for at least 30 minutes before downloading, but at a fairly
    low sampling rate (tens or hundreds of samples per second, not thousands).

    And, of course, the budget for this project is very limited. So, my question
    for the group:

    1) Do you know of (or own) a system that can do this?
    2) Who makes it? If it is home made, would you share the plans/schematics?
    3) If you represent the company, would you lend or lease this equipment for a
    short period of time?

    Replies will be summarized and posted. Thanks in advance.

    Marc
