Postural instability is a commonly encountered problem in elderly population. In a large number of persons this can be attributed to the physiological changes associated with aging. To investigate the changes in postural stability with aging this study was conducted in 64 healthy volunteers aged eight to seventy years using dynamic posturography. Three tests, namely sensory organization test, limits of stability and rhythmic weight shift which included a total of ten parameters were done. Of these, equilibrium score, strategy score, reaction time, movement velocity and on axis velocity showed statistically significant deterioration with progression of age. Disturbances in postural stability were detected from the fourth decade onwards in the population studied. This instability was not related to any disease process and possibly reflects the process of aging. Adequate precautionary measures should be taken by elderly persons to avoid the possible adverse consequences of postural instability.
姿势不稳是老年人群中常见的问题。在大量人群中，这可归因于与衰老相关的生理变化。为了研究姿势稳定性随衰老的变化，本研究使用动态姿势描记法对64名年龄在8至70岁的健康志愿者进行了调查。进行了三项测试，即感觉组织测试、稳定性极限和节律性体重转移，共包括十个参数。其中，平衡分数、策略分数、反应时间、运动速度和轴向速度随年龄增长显示出统计学上的显著恶化。在所研究的人群中，从第四个十年开始就检测到姿势稳定性的干扰。这种不稳定性与任何疾病过程无关，可能反映了衰老过程。老年人应采取适当的预防措施，以避免姿势不稳可能带来的不良后果。
