  • Placement of centroids on foot

    I was hoping that someone could help solve my problem. I am trying to
    measure maximum toe clearance in a gait study. My problem is that if I
    place the centroid, for automatic digitizing with PEAK, on the toe, it
    will do one of two things. The first one that I have noticed deals with
    the centroid rubbing on the ground and eventually falling off the toe.
    The second one is that the subjects realize that there is a problem with
    the centroid rubbing on the ground so they adjust there walking to avoid
    the problem.

    I avoided this the first time by not using centroids and manually
    digitizing fixed points on the foot. This method did give acceptable
    results but took hours to accomplish. I hope that I, with your help, can
    solve this small problem.

    Thank You,
