摘　　要：目的　探讨正常人静态平衡姿势图的影响因素。方法　用平衡仪对 588例正常人进行静态平衡功能测试 ,用t检验对各年龄组性别之间的平衡参数值进行分析。用典则相关分析方法按性别分组对年龄、身高和体重与平衡姿势图的参数值进行相关分析。结果　性别之间的平衡参数值差异有统计学意义(P <0 .0 1～ 0 .0 5) ;年龄与男、女两组的平衡参数值均呈正相关 ;女性组身高与平衡参数值呈正相关 ,男性组身高与平衡参数值相关性低 ;男女两组的体重与平衡参数值均呈正相关。结论　性别和年龄影响平衡功能 ,随着年龄的增加平衡功能下降 ,36～ 50岁和 51～ 65岁的男性平衡功能较女性差 ,2 0～ 35岁和 66～ 79岁的女性平衡功能较男性差 ;随着体重增加 ,平衡功能下降 ;随着身高的增加 ,女性平衡功能下降 ,而身高对男性平衡功能影响不显著。Objective To study the effect factors and sensitive parameters in normal subjects with static posturography. Methods A computerized stabilometer was used to evaluate 588 normal subjects in the eyes closed condition. t test was used to analyze gender factors in every age group, canonical correlation analysis method to analyze the relative effect of age, body height and body mass factors and the static posturography parameter values. Results The parameter values between gender showed significant difference ( P <0.01～0.05); Age was positively related to balance parameter values in both genders; The correlation between body height and balance parameter values in both genders was lower; The relationship between body mass and balance parameter values was positive in male group, but lower in female group. The sensitive parameters are the maximum sway amplitude and mean sway amplitude in X and Y directions, path length, covered area, area speed, average sway speed and sway speed in Y direction. Conclusion Gender and age affect balancing ability, the older, the poorer stabilization; Gender associated differences were significant for some sway components in the middle and older age groups (36～50 and 51～65 years) in which men exhibited more spontaneous postural sway than women. The younger and oldest aged women (20～35 and 66～79 years) exhibited significantly more postural sway than men of the same age. In the youngest age group (15～19 years) no gender related differences in postural sway were found. As the body mass increased, the balancing ability decrease in male group, but no change in female group. Body height had no effect in both gender groups.
