这项研究比较了380名年轻人，342名一般健康的老年人没有不平衡障碍，和一组33名老年人不平衡障碍的身体摇摆特征。使用数据采样频率为20 Hz的Anima's stabilometer G5500测量足部压力中心（COP）1分钟。四个高可靠性的措施被用来评估身体摇摆（单位时间摇摆，前后摇摆，左右摇摆，和高频段功率）。单位时间摇摆，左右摇摆，高频带功率显着较大的老年人组与不平衡障碍，和较小的健康老年人和年轻人，在该顺序。前后摇摆在平衡失调的老年人和健康老年人中明显大于年轻人。与年轻人以及健康的老年人相比，患有不平衡障碍的老年人具有更大和更快的摇摆，特别是在左右方向上。看来，年龄的增长与前后摇摆的较大影响有关。
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.
