Abstract: Objective:To explore any changes with age in the center of plantar pressure among normal people after walking.Methods:Fifty healthy subjects were divided into a young group and an elderly group, each of 25. Gait descriptors were collected for each subject using a model AL-600 gait and balance training and evaluation apparatus. The gait descriptors were the center of pressure displacement (COPD), and the COPD in the medial-lateral (COPD-X) and anterior-posterior (COPD-Y) directions before and after 10 and 15 minutes of walking.Results:The average COPD, COPD-X and COPD-Y of the elderly group increased after both 10 and 15 minutes of walking, but among the young group increases were observed only after 15 minutes. The average COPD, COPD-X and COPD-Y of the elderly group were always significantly larger than the young group′s averages.Conclusions:Gait stability among the elderly decreases after as little as 10 minutes of walking, but among the young decreases are observed only after 15 minutes.
