项目摘要

It is important for the quality of life of the aged peoples that they keep independent in daily life by minimizing the deteriorate of physical and brain function caused by aging. The body equilibrium required in daily life is kept by postural reflexes and various muscle functions. Recently, it has been considered that the occlusion might provide various effects to the body balance. The purpose of this study was to investigate the relationship between the occlusion and physical functions. We focused on the gait movement which is one of the basic motions in daily life and examined that the occlusion could effect the gait stability, that is body equilibrium.First, twelve young healthy subjects volunteered to particiopate in this study. It was investigated the effect of different mandibular positions on the body equilibrium by measuring the gait motion. Subjects were instructed to walk with the various occlusal splints which gave different mandibular positions. Gait cycle, coefficient of v … More ariation for gait cycle and gait velocity were calculated. One-way ANOVA with repeated measures demonstrated gait cycle, coefficient of variation and gait velocity at fast speed changed significantly in 5mm opning position from the intercuspal position, and in 5mm left and 5mm right position from the 3mm opning position at fast speed(p<0.05). The result of this study suggested that the change of mandibular position could affect the gait stability.Second, healthy edentulous subjects volunteered to participate in this study. It was investigated the effect of occlusal rehabilitation with complete denture on the body equilibrium by measuring gait motions. The gait motions were recorded when wearing old dentures, just after inserting new dentures and after completing their adjustments. Those measurements were carried out when wearing dentures with or without occlusion, and without dentures. Gait analysis was performed as same as the first. Two-way ANOVA demonstrated that the gait stability tended to improve when wearing new dentures after completing adjustments compared with when wearing old dentures. Less

对于老年人的生活质量而言，他们在日常生活中保持独立，这一点很重要，可以最大程度地减少衰老引起的身体和脑功能的检测。日常生活中所需的身体等效由姿势反射和各种肌肉功能保留。最近，人们认为闭塞可能会为人体平衡带来各种影响。这项研究的目的是研究遮挡和物理功能之间的关系。我们专注于GET运动，这是日常生活中的基本运动之一，并检查了闭塞可能会影响GET稳定性，即身体等效。首先，在这项研究中自愿参加了十二名年轻健康的受试者。通过测量GET运动，研究了不同下颌位置对身体当量的影响。指示受试者与各种咬合夹板一起行走，这些夹板具有不同的下颌位置。步态循环，V的核心…用于获取周期和获取速度的更多算术。具有重复度量的单向方差分析表明，从次峰位置，在5mm Opning位置以及从3mm Opning位置的5mm Opning位置在5mm Opning位置下以5mm Opning位置在快速速度的5mm Opning位置下，在5mm Opning位置下，以3mm Opning位置在快速速度下以5mm的左和5mm的位置发生了明显变化（p <0.05）。这项研究的结果表明，下颌位置的变化可能会影响生病性。第二，健康的饮食受试者自愿参加了这项研究。通过测量拟态，研究了咬合康复对身体等效物的影响。插入新牙科和完成调整后，插入新牙科后，记录了Aitmotions。这些测量是在戴牙科或不遮挡的牙齿时进行的，并且没有假牙。步态分析与第一个进行一样。双向方差分析表明，与穿老牙医相比，完成调整后穿新牙医后，步态稳定性往往会有所改善。较少的
