[目的]本研究的目的是通过对足压力中心和质心摇摆的相互关系分析，探讨静立控制的特点。【研究对象】20名老年人参与本研究。[方法]采用三维运动分析系统，建立头部、胸部和骨盆区域的节段模型。利用三维系统测量了人体和各部分的质心摆动，以及在测力板上的足部压力摆动中心。[结果]结果显示，头部质心与足部压力中心的相关系数峰值在中外侧方向上明显低于身体质心。[结论]本研究结果表明，头部质心向中外侧偏移与足部压力中心偏移的相关性较低；因此，老年人安静站立时其他身体部位的质心摆动可能是独立控制的。
: [Purpose] The purpose of this study was to investigate the characteristics of quiet standing control using cross-correlation analysis of the center of foot pressure and the center of mass sway. [Subjects] Twenty elderly individuals participated in this study. [Methods] Using a 3D motion analysis system, we created segment models of the head, thoracic, and pelvic regions. The 3D system was used to measure the center of mass sway of the body and of each segment, as well as the center of foot pressure sway on a force plate. [Results] The results revealed that the correlation coefficient peak value of the center of mass of the head and the center of foot pressure showed a significantly lower value than the center of mass of the body in the mediolateral direction. [Conclusion] The results of this study indicate that the center of mass sway of the head in the mediolateral direction has a low association with the center of foot pressure sway; therefore, the center of mass sway of the other body segments of elderly individual during quiet standings is possibly controlled independently.
