Abstract

Human gait demonstrates stride-to-stride variability. This study quantifies the minimum number of cycles which are required to obtain a precise representation of a subject's gait during a testing session. Ninety-two clinical studies from 72 subjects were evaluated. Two levels of error were considered. At least seven gait cycles are needed to obtain temporal-distance data which is low in precision, whereas at least 22 gait cycles are needed to obtain more precise data.
