Prevent the infant's fall. The relation of infant's reduced occlusal force and fall.

本研究以321名健康小学生(平均年龄11.16岁，标准差0.57岁)为研究对象，研究被认为与运动能力提高有关的咬合是否有助于改善小学生的平衡功能。平衡能力的评估使用EquiTest系统[0！R]，该系统测量由于背部快速移动而产生的重心摆动，以及作为外部干扰的力与力盘。咬合力测量采用GM10型咬合力计。数据将是延迟(Ms)、权重对称和强度对称。数据比较采用方差分析(ANOVA)。统计软件使用SAS统计软件包和8.2版(SAS Institute Inc.)。结果，咬合力和潜伏期之间存在显著差异(p&lt；0.01)。在重量对称性(p=0.4928)和强度对称性(p=0.9045)方面，差异无统计学意义。综上所述，咬合力与潜伏期之间存在交互作用。因此，一个人的咬合力越强，他或她的平衡指数的潜伏期就越好。这项研究表明，更强的咬合有助于更好地预防站立姿势发生意外摆动时的平衡失调和婴儿摔倒。

This study aimed to examine whether the occlusion assumed to be related to the improvement of sports ability contributes to the improvement of a balance function in elementary students.321 healthy elementary students (mean age, 11.16 ; standard deviation (SD) 0.57 years) with no equilibrium or stomatognathic function abnormalities were examined. Balancing ability was evaluated using the EquiTest system[○!R], which measures sway of the center of gravity produced by rapid movement of back and force as an external disturbance with Force Plate. For the occlusal force, OCCLUSAL FORCE-METER GM10 was used. Data was to be Latency(ms), weight symmetry, and strength symmetry. This data was compared by analysis of variance (ANOVA). For the Statistical software, the SAS statistical package and version 8.2 (SAS Institute Inc) was used.Consequently, significant difference was observed between occlusal force and Latency (p<0.01). As for weight symmetry (p=0.4928) and strength symmetry (p=0.9045), a significant difference was not found. In conclusion, an interaction between occlusal force and Latency was found. Therefore, the tendency that the stronger occlusal force a person has, the better Latency the index of the balance he or she has is seen.This study suggested that stronger occlusion contributes to better prevention of the overbalance and infant's fall when unexpected sway occurs in the standing position.
