目的：目的：探讨全口义齿修复对患者站立和行走姿势控制的影响。所有受试者均佩戴全口义齿，必要时调整义齿或更换新义齿。测量在两种条件下进行：戴假牙和不戴假牙。站立稳定性以重心轨迹为评价指标，步态稳定性以步态速度、步幅和步态周期为评价指标。此外，步态稳定性也评价了最大加速度，最大角速率，横向平衡，均方根和谐波比与三轴加速度计在66 Hz的采样率。质心位置、步态速度、步态周期和步长的差异采用配对t检验（P < 0.05）。结果：戴用义齿后，患者的重心轨迹明显缩短，步态速度和垂直角频率的谐波比明显增加，而其他参数无显著性差异。全口义齿产生的影响，在静态和动态conditions.Conclusions的稳定性无牙患者：这些结果表明，戴全口义齿可能是一种有效的援助，以保持和改善平衡和控制老年人。(C)2009年日本口腔修复学会。由Elsevier爱尔兰出版。All rights reserved.
Purpose: To investigate the influence of wearing complete dentures on postural control in standing and walking.Methods: Thirty-four edentulous patients participated in this study. All the subjects were wearing complete dentures, and the dentures were adjusted or replaced with new dentures when necessary. Measurements were performed under two conditions: wearing dentures and not wearing dentures. Standing stability was evaluated by the locus of center of mass, and gait stability was evaluated by the gait velocity, stride and gait cycle. In addition, gait stability was also evaluated by the maximum acceleration, maximum angle rate, lateral equilibrium, root mean square and harmonic ratio with a tri-axial accelerometer at a sampling rate of 66 Hz. Differences for the locus of center of mass, gait velocity, gait cycle and stride length were assessed with the paired t test (P < 0.05). Other outcomes were compared with the Wilcoxon signed- rank test (P < 0.05).Results: With denture wear, the locus of center of mass was significantly shortened, and the gait velocity and harmonic ratio of the vertical angle rate were significantly increased; though other parameters showed no differences. Complete dentures produced an effect on the stability of edentulous patients under both static and dynamic conditions.Conclusions: These results indicate that wearing complete dentures may be an effective aid to maintain and improve balance and control for elderly people.
