1. A method for analyzing motion of a foot of a person relative to a surface, comprising steps of:

  • (a) using an accelerometer that does not require compression forces thereon to sense acceleration to sense an acceleration of the foot and to provide a signal indicative of the acceleration of the foot;

    (b) providing the signal from the accelerometer to a signal processor; and

    (c) using the signal processor to analyze the signal to determine a moment that the foot leaves the surface during a footstep taken by the person.
