  • Re: Noraxon EMG Systems

    While I have not used it personally, our lab has a Noraxon for EMG and
    data collection. It has proved to be **Extremely** troublesome. It has
    involved our determining the calibration - there was a gain factor which
    was not known, our sending several parts back to Finland many times and
    lots of figuring out what was in the black box. I know that one of my
    colleagues went to the company's booth at more than one conference and
    said that he would stand at their booth and tell everyone to not buy
    their system until they came to our lab to determine what was wrong with
    it. They came - but they couldn't solve it. This happened more than
    once. We have collected some good data with it, but more often than not
    it will be fine one day, then without touching anything it the receiver
    will be overloaded or signals will be junk the following day. If I
    understand correctly, the company in the U.S. knows nothing (or next to
    nothing) about the hardware in the system. I would approach the purchase
    with extreme caution. Good luck.
