1. For use with a walking surface and left and right feet, a device for measuring human ambulation comprising:
- (a) a left foot sensor capable of sensing when the left foot is in contact with the walking surface, the left foot sensor being activated when such contact occurs;
(b) a right foot sensor capable of sensing when the right foot is in contact with the walking surface, the right foot sensor being activated when such contact occurs;
(c) a processor having an algorithm to create an ambulation index reflective of a quantitative analysis of human ambulation;
(d) left transmission means for indicating to the processor when the left foot sensor is activated;
(e) right transmission means for indicating to the processor when the right foot sensor is activated; and
(f) output means to output the ambulation index from the processor.

Abstract
A device comprising a system of switches and sensors placed inside a person'"'"'s footgear which send positional information through wireless telemetry from a transmitter to a receiver. This positional information is entered into a computer and processed according to prestored algorithms, yielding a non-dimensional ambulation index. This invention also comprises a method for calculating the non-dimensional ambulation index.
