abstract="BACKGROUND: Aging, being a natural process, involves many functional and structural changes within the body. Identifying the age-related postural changes will provide  insight into the role of aging on postural control during locomotion. The aim of  this study was to identify age-related postural changes during a transitional task  under different conditions. <br><br>METHODS: Sixty healthy females divided into three age  groups: A (50-60 y/o), B (60-70 y/o), and C (70-80 y/o). The transitional task was  measured by two force platforms. The procedure consisted of three phases: quiet  standing, transfer onto a second platform, and quiet standing on the second  platform. Four different conditions were applied: unperturbed transfer, obstacle  crossing, step-up, and step-down. Double-support time, transit time, and stability  time before and after the step task were analyzed. <br><br>RESULTS: The transit time was  longer by 30% for subjects over 70 y/o. The double-support time was longer by 11%  among adults 60-70 y/o, while in people over 70 y/o it was longer by almost 50%  compared to the 50-60 y/o subjects. The stability time before the transitional task  was longer by 17% among adults over 60 y/o compared to middle-age subjects. The  stability times before and after the transitional task were longer for adults in the  50-60 y/o category. <br><br>CONCLUSION: The proposed procedure is adequate for assessing  age-related changes in postural control while undergoing a transitional task. An  analysis of the double-support time and stability time before and after the step  task enabled the detection of early signs of balance changes in middle-age adults. Independent of age, the transitional task parameters changed with the increasing  difficulty of the tasks.<p /> <p>Language: en</p>",
