Age-related changes in postural control in older women: transitional tasks in step initiation

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