应用ＳＴ－９３９人体重心平衡仪对我院职工健康体验的７８０名进行立位平衡功能测试，重点分析三项参数：外圆面积、轨迹长度，平均速度，结果显示：（１）２１－５０岁年龄范围内姿态稳定性最佳、其外圆面积小，轨迹短．速度慢．７０岁以上年龄组姿态控制力下降。各项参数值较大（Ｐ＜０．０１）．（２）视觉影响姿态稳定性．各年龄组三参数闭眼值均大于睁眼（Ｐ＞００１）。（３）性别对姿态控制无明显关系（Ｐ＞０．０５）。
The ST-939 human body center-of-gravity balance meter was used to test the stand-balance function of 780 health workers in our hospital. The analysis focused on three parameters: cylindrical area, path length and average speed. The results showed that: (1) Gesture within the best age stability, its small area of the outer circle, short track. Slow. Age control over 70 years old decreased. The value of each parameter is larger (P <0.01). (2) Visual effects on attitude stability. The closed eyes of all three parameters in all age groups were greater than eyes open (P> 001). (3) Gender had no significant relationship with attitude control (P> 0.05).
