The study compared body-sway characteristics of 380 young adults, 342 generally healthy elderly without disequilibrium disorders, and a group of 33 elderly with disequilibrium disorders. Center of foot pressure (COP) was measured for 1 min. using an Anima's stabilometer G5500 with a data sampling frequency of 20 Hz. Four high reliability measures were used to evaluate body sway (unit time sway, front-back sway, and a left-right sway, and high frequency band power). Unit time sway, left-right sway, and high frequency band power were significantly larger for the group of elderly with disequilibrium disorders, and smaller for the healthy elderly people and young adults, in that order. Front-back sway was significantly larger in the elderly with disequilibrium disorders and healthy elderly than in young adults. The elderly with disequilibrium disorders had a larger and faster sway than young adults as well as the healthy elderly, particularly in the left-right direction. It appears aging was specifically associated with larger influence on the front-back sway.
本研究比较了 380 名年轻成年人、342 名无平衡障碍的一般健康老年人和 33 名有平衡障碍的老年人的身体摆动特征。使用 Anima 的 G5500 稳定计，以 20 Hz 的数据采样频率测量了 1 分钟的足底压力 (COP)。使用了四个高可靠性指标来评估身体摆动（单位时间摆动、前后摆动和左右摆动以及高频带宽功率）。有平衡障碍的老年人的单位时间摆动、左右摆动和高频带宽功率明显较大，而健康老年人和年轻成年人的摆动则较小。前后摆动在有平衡障碍的老年人和健康老年人中明显大于年轻人。有平衡障碍的老年人的摆动幅度和速度比年轻人以及健康老年人都要大，尤其是在左右方向。似乎衰老与前后摆动的影响更大有关。
