[Purpose] The aim of this study was to determine whether insoles change standing balance on the ground in normal and flat-footed subjects. [Subjects] Twenty subjects with flatfeet and 20 subjects with normal feet were included in this study. [Methods] Body sway was evaluated based on the center of pressure while subjects stood on the ground. Body sway was measured during upright standing with the feet 10 cm apart for 30 seconds. The total locus length and the area of body sway were then measured using a zebris system. Measurements were made under three sets of conditions: using BMZ insoles, which supported the cuboid; using Superfeet insoles, which supported the medial longitudinal arch; and with no insoles. [Results] The 3 insole conditions were compared. On level ground, the total locus length for the Superfeet insole was significantly less than those for the BMZ insole and no insole. [Conclusion] On level ground, Superfeet feet insoles were effective in stabilizing standing balance in both flat-footed and normal-footed subjects.
[目的]本研究旨在确定鞋垫是否会改变正常足和扁平足受试者在地面上的站立平衡。[受试者]本研究纳入了20名扁平足受试者和20名正常足受试者。[方法]当受试者站立在地面上时，基于压力中心评估身体摇摆。在双脚分开10厘米直立站立30秒期间测量身体摇摆。然后使用zebris系统测量身体摇摆的总轨迹长度和面积。测量在三组条件下进行：使用支撑骰骨的BMZ鞋垫；使用支撑内侧纵弓的Superfeet鞋垫；不使用鞋垫。[结果]比较了三种鞋垫条件。在平坦地面上，Superfeet鞋垫的总轨迹长度显著小于BMZ鞋垫和不使用鞋垫时的总轨迹长度。[结论]在平坦地面上，Superfeet鞋垫对稳定扁平足和正常足受试者的站立平衡有效。
