压力中心通常用于评估站立平衡。尽管它是不完整的，没有更好的评价方法已经提出。我们设计了三种站立姿势的实验：双脚并拢站立，双脚分开与肩同宽站立，双脚略宽于肩同宽站立。我们基于平台的压力系统收集瞬时足底压力（站立足迹）。定义了瞬时站立足迹主轴的物理量，并将其作为评价站立平衡的指标。将新建立的指标与压力中心指标评价不同站立姿势稳定性的结果进行比较，发现站立足迹主轴指标能更好地反映站立姿势的变化。分析表明，人体对脚间相对位置的不敏感反应和对人体站立姿势从身体中心位置改变的不敏感反应是人体运动的主要特征。
Center of pressure is commonly used to evaluate standing balance. Even though it is incomplete, no better evaluation method has been presented. We designed our experiment with three standing postures: standing with feet together, standing with feet shoulder width apart, and standing with feet slightly wider than shoulder width. Our platform-based pressure system collected the instantaneous plantar pressure (standing footprint). A physical quantity of instantaneous standing footprint principal axis was defined, and it was used to construct an index to evaluate standing balance. Comparison between results from our newly established index and those from the center of pressure index to evaluate the stability of different standing postures revealed that the standing footprint principal axis index could better respond to the standing posture change than the existing one. Analysis indicated that the insensitive response to the relative position between feet and to the standing posture change from the center of p...
