目的:在定量分析儿童静态平衡的基础上.探讨性别、年龄对儿童静态平衡功能的影响.方法:采用KY-1112平衡分析系统,对6-8岁254名男童和245名女童,分别在睁、闭眼状态下测试其静态平衡的各项指标.结果:①6-8岁儿童静态平衡功能性别的比较,在睁眼状态下有3指标差异存在显著性(P<0.05),在闭眼状态下有3项指标差异存在非常显著性(P<0.01).②年龄比较,6-8岁儿童静态平衡在5项指标上差异存在显著性(P<0.05).具体为在指标包络面积(睁闭眼状态下)和轨迹位置均方差(睁眼状态下)上,8岁分别和6岁7岁间存在非常显著性差异(P<0.01),6岁和7岁之间差异无显著性;在指标轨迹长度(睁闭眼状态下)上,6岁、7岁、8岁相互间差异存在非常显著性(P<0.01);这五项有差异指标的均值随着年龄的增大而减小.③指标重心曲线最小矩形长度与宽度的比值小1.结论:6-8岁儿童静态平衡功能在性别上差异存在显著性,女童的平衡功能好于男童;在年龄上存在显著性差异,整体趋势是静态平衡功能随着年龄的增大而增强;其重心动摇面积分布为前后大于左右.

Objective:To explore the influences of different sexes and ages on children static balance at the basis of quantitative comparison study of static postural balance of children aged 6-8(-year-odl).Method:A total of 499 children aged 6-8-year-old were recruited,which include 254 boys and 245 girls.Static postural balance test of these subjects was performed by using KY-1112 system for stabilometric analysis with subjects opening and closing eyes situations.Result:①There was a significant gender difference in static balance.At gender comparison,there was a significant difference on 3 indicators at the situations with eyes opening(P<0.05),and 3 indicators at the situations with eyes closing(P<0,01).②A significant difference Was shown in age comparison on 5 indicators(P<0.05).The mean of 5 indicators decreased with age growing.As compared with the value among Eve Area(with eyes opening and closing)and Track location Variance (with eyes opening).there Was a significant difference between children aged 8-year-old and 6-7-year-old(P<0.01),and no significant difference between 6-year-old and 7-year-old.There was a very significant difference on the LNG indicators at the situations with eyes opening and closing(P<0.01).③The value R indicator Was less than 1.Conclusion:To the children aged 6-8-year-old,there was significant gender difference in static balance,the balance function of girls was better than that of boys;there was significant age difference in static balance,with age growing the static balance rose also;relatively speaking,the gravity center shaking area was larger at forward and backward than that at leftward and rishtward.
