Aging causes a progressive worsening in postural balance, affecting functional independence and increasing the risk of falls.
The aim of the study was to evaluate the effect of aging on the static balance in women from 50-years to 89-years of age.
This was a cross-sectional study, with 400 irregularly active women were evaluated and grouped by age: Group 6 decade (age 50 to 59) ‒ 58 participants; Group 7 decade (age 60 to 69) ‒ 214 participants; Group 8 decade (age 70 to 79) ‒ 92 participants; Group 9 decade (age 80 to 89) ‒ 36 participants. Postural balance was evaluated using a portable force platform in a standard standing position, with Eyes Open (EO) and Eyes Closed (EC).
In the two measurement conditions, the elderly women in Group 9 decade presented mediolateral displacement and range, and mean velocity greater than the women's values in Groups 6 and 7 decade. In the EO e EC situation, the displacement was higher in the elderly Group 9 decade compared to younger groups. Group 8 has a mean velocity greater than Group 6 decade in the EO situation.
Posturography showed a decline in postural balance with advancing age, suggesting that the 9 decade of life is a borderline age to this detriment due to an increase in postural instability.
衰老导致姿势平衡逐渐恶化，影响功能独立性，并增加跌倒风险。
本研究旨在评估女性从 50 岁到 89 岁年龄增长对静态平衡的影响。
这是一项横断面研究，共评估了 400 名非规律运动的女性，并按年龄分组：60 岁组（年龄 50 至 59 岁）-58 名参与者；70 岁组（年龄 60 至 69 岁）-214 名参与者；80 岁组（年龄 70 至 79 岁）-92 名参与者；90 岁组（年龄 80 至 89 岁）-36 名参与者。使用便携式力平台在标准站立位置评估姿势平衡，睁眼（EO）和闭眼（EC）两种状态。
在两种测量条件下，90 岁组的老年女性在中侧向位移和范围以及平均速度方面均大于 60 岁和 70 岁组的女性。在 EO 和 EC 情况下，90 岁组老年人的位移高于年轻组。在 EO 情况下，80 岁组的平均速度大于 60 岁组。
姿势描记术显示，随着年龄的增长，姿势平衡能力下降，这表明 90 岁是一个容易出现姿势不稳定的临界年龄，会导致这种损害。
