[Purpose] The purpose of this study was to investigate the psychometric properties of the lower extremity subscale of the Fugl-Meyer Assessment lower extremity (FMA-LE) for community-dwelling hemiplegic stroke patients. [Subjects] The participants were 140 community-dwelling hemiplegic stroke patients. [Methods] To determine the psychometric properties of the FMA-LE, we examined construct validity, response characteristics, item discrimination, and internal consistency. [Results] Factor analysis of the FMA-LE revealed that the first factor explained 61.73% of the variance and provided evidence of unidimensionality. The FMA-LE did not show ceiling or floor effects; Cronbach's α was 0.935 (95% CI: 0.919-0.950). [Conclusion] Because the FMA-LE seems to be both valid and reliable, we conclude that it is appropriate for the measurement of the lower extremity motor impairment of community-dwelling hemiplegic stroke patients.
[目的] 本研究旨在探讨Fugl-Meyer评估下肢量表（FMA-LE）下肢分量表用于社区居住的偏瘫中风患者时的心理测量学特性。[对象] 参与者为140名社区居住的偏瘫中风患者。[方法] 为确定FMA-LE的心理测量学特性，我们检验了结构效度、反应特征、项目区分度和内部一致性。[结果] FMA-LE的因子分析显示，第一个因子解释了61.73%的方差，并提供了单维度性的证据。FMA-LE未显示天花板效应或地板效应；Cronbach's α为0.935（95% CI：0.919 - 0.950）。[结论] 由于FMA-LE似乎既有效又可靠，我们得出结论，它适用于测量社区居住的偏瘫中风患者的下肢运动障碍。
