  • measure of step lenght

    Dear Biomech-L readers,
    I would like measure the successive step lengths over 100 and more strides
    of healthy and hemiparetic gait in our rehabilitation unit. Therefor I'm
    looking for a small device, which measures the maximum distance between
    both legs and is fixed at the ankles. I think about ultra sonics or
    electrical conductive elastomere. The data should be transferred by a
    radiotransmitter or collected in a memory card data logger.
    I would be grateful if someone could help me with manufacurers or
    supplierers (including fax/ohone number if possible).
    The data will be used to evaluate the long time success of our gait
    training in the neurological rehabilitation of stroke patients.
    A other need is the information about 100% working foot switche - products
    to estimate the heel-on and toe-off contact in rehabilitation. Becouse
    the patients touch the ground with other points of his/her foot soles
    as this a healthy person does, we have difficulties. There are some
    comments about this ? I will collect the answers and return all to the
    Many thanks
