摘要：

      摘要 目的：探讨中文版8字步行测试（F8WT）评定脑卒中患者步行功能的信度及效度，为该量表的临床应用提供客观依据。 方法：60例患者参加了本研究，对患者进行F8WT、10m步行测试（10MWT）和“起立-行走”计时测试（TUGT），并在2天内完成F8WT第二次评定。对两次F8WT的结果作相关性分析测试其信度；将F8WT速度与10MWT、TUGT速度作相关性分析检验其效度。 结果：F8WT两次测试结果高度相关，重测信度组内相关系数ICC=0.884—0.986，测量者间信度ICC=0.772—0.998；F8WT速度与10MWT、TUGT速度高度相关（r=0.896，r=0.921）。 结论：中文版8字步行测试具有良好的信度及效度，可用于脑卒中患者步行功能的评价。

Abstract:

      Abstract Objective： To translate the figure-of-8 walk test into Chinese(F8WT-C) and to explore its reliability and validity. Method： sixty stroke patients were recruited. Test-retest and inter-rater reliability were analyzed with intraclass correlation coefficient(ICC) test. Validity was estimated by comparing the F8WT-C to 10-Meter Walk Test(10MWT) and Timed “Up and Go” Test(TUGT). Result： ICC was 0.884—0.986 for test-retest reliability and 0.772—0.998 for inter-rater reliability. F8WT-C was highly correlated with 10MWT and TUGT in speed(r=0.896， r=0.921). Conclusion： This study supports the reliability and validity of F8WT as a measure of walking function after stroke. F8WT can be used in clinical practice.
