The purpose of this study is to determine how the control of covariates (height, weight, and walking speed) affects the changes in gait performance and gait variability in walking of 9-year-old children and young adults in their 20s. It is to understand how age affects actual gait performance and variability regardless of physical condition. Thirteen male 9-year-old children (9.43±0.19) and 13 young adults (21.69±1.60) living in the community, a total of 26 participants participated in this study. Participants wore 7D IMU sensors on both feet and walked for 6 minutes. From the data measured through the 6-minute walk, the gait performance variables was calculated as the average value of measured gait parameters. Gait variability was calculated by defining CV values of the measured gait parameters. As a result of performing ANCOVA controlled by a covariate in the gait performance comparison, there was no difference in performance between children and young adults, and there was a difference in gait variability in gait cycles (s), cadence (step/min), and stride length (m). This shows that children"s gait shows high variability due to lack of physical condition and gait speed as well as muscle strength and muscle nerve control ability compared to adults, and that gait regulation process is highly likely to be incomplete. This conclusion suggests that gait variability should be a factor in determining effective gait characteristics in children"s gait studies.
