[Purpose] The purpose of this study was to compare the gait parameters of age-matched people with a normal gait (≥ 65 years), age-matched people with knee pain, and age-matched people with walker dependent gait at a self-selected gait speed. [Methods] Subjects walked on even ground in bare feet and were allowed a natural arm swing on a 6-m walkway. Walker-dependent participants walked on a walkway without a walker. [Results] The kinematic and spatiotemporal gait characteristics were used to investigate the difference among the each group. Hip flexion, knee flexion, and stride width parameters were not different. The gait speed, stride length and time, hip and knee extension, and ankle flexion and extension parameters were significantly different. [Conclusion] A comparision of kinematic and spatiotemporal gait characteristics during gait may provide an insight into the gait pattern of normal elderly people, those with knee pain, and the walker-dependent elderly.
[目的] 本研究旨在比较年龄匹配的正常步态人群（≥65岁）、年龄匹配的膝关节疼痛人群以及年龄匹配的依赖助行器步态人群在自选步态速度下的步态参数。[方法] 受试者赤足在平坦地面行走，在6米长的通道上自然摆动双臂。依赖助行器的参与者在没有助行器的通道上行走。[结果] 运用运动学和时空步态特征来研究各组之间的差异。髋关节屈曲、膝关节屈曲和步幅宽度参数无差异。步态速度、步长和时间、髋关节和膝关节伸展以及踝关节屈伸参数有显著差异。[结论] 比较步态过程中的运动学和时空步态特征可能有助于深入了解正常老年人、膝关节疼痛老年人以及依赖助行器老年人的步态模式。
