[Purpose] The purpose of this study was to examine the effects of a functional foot orthosis on the knee angle in the sagittal plane of college students in their 20s who had flatfoot. [Subjects and Methods] The subjects of this study were 20 college students diagnosed as having flatfoot. The variations of their knee angle (Q-angle) in the sagittal plane during the stance phase were measured using the VICON Motion System (Vicon, Hansung, Korea) before and while wearing a foot orthosis. The experimental data were analyzed using SPSS 12.0 for Windows. [Results] The Q-angle in the test group during the stance phase showed statistically significant declines on the right and left sides while wearing the foot orthosis during the gait-phases of loading response and midstance. During initial contact, terminal stance, and preswing, the Q-angle also decreased on the right and left sides after wearing the foot orthosis, but the changes were not statistically significant. [Conclusion] The college students with flatfoot exhibited declines in the Q-angle in the sagittal plane while wearing a foot orthosis. In this regard, the application of active gait training using orthotic shoes for long hours is likely to help individuals with flatfoot to achieve normal gait.
[目的]本研究旨在探讨功能性足部矫形器对20多岁患有扁平足的大学生矢状面膝关节角度的影响。[对象与方法]本研究的对象为20名被诊断为扁平足的大学生。在穿着足部矫形器之前和期间，使用VICON运动系统（Vicon，韩国汉城）测量他们在站立期矢状面膝关节角度（Q角）的变化。使用Windows版SPSS 12.0对实验数据进行分析。[结果]在步态的负重反应和支撑中期阶段，测试组在穿着足部矫形器时，站立期的右侧和左侧Q角均出现统计学上的显著下降。在初始接触、终末支撑和摆动前期，穿着足部矫形器后右侧和左侧的Q角也有所下降，但变化无统计学意义。[结论]患有扁平足的大学生在穿着足部矫形器时矢状面Q角下降。在这方面，长时间使用矫形鞋进行主动步态训练可能有助于扁平足患者实现正常步态。
