ABSTRACT:
To characterize the gait of a subject, a treadmill having a movable support surface is provided with multiple transducers mounted beneath the movable support surface. The subject performs locomotion on the movable surface. The computer accepts a series of signals from each transducer and identifies the occurrence of heel-strike and toe-off. The computer identifies the subject's activity as walking or as running. The computer identifies two non-contiguous groups of transducers that are measuring a force greater than zero associated with the two feet and calculates quantities related to the forces exerted by each foot during each phase of walking or running.
