MOTION ANALYSIS: ONE VERSUS TWO STRIDE ANALYSES

Abstract

The purpose of this study was to analyze two consecutive strides and compare results of gait and posture between the first stride, second stride and mean of the two strides. Two strides were filmed and digitized for 36 children at both 100m and 900m on three separate occasions. Head and trunk f1exion, stride length, stride rate and double support time were recorded. No significant differences were found between the first, second and mean of the two strides for trunk! head flexion and stride length. Differences were recorded between the first and second stride in stride rate and double support time, although neither stride was significantly different from the mean of the two strides. It was concluded that only one stride need to be digitized for an accurate representation of posture and gait.
