To investigate the intra-rater absolute reliabilities and validity of the Figure of-Eight Walk test (F8WT) in patients with chronic stroke. A total of 36 subjects with chronic stroke participated in this study. The inter-rater reliability of F8WT was calculated using intra-class correlation coefficients($ICC_{2,1}$). Moreover, we used the standard error measurement (SEM) and the small real difference (SRD) to examine the absolute reliability indices. The validity was demonstrated by a spearman correlation of F8WT with Postural Assessment Scale for Storke(PASS) and Trunk Impairment Scale(TIS). The inter-rater reliability of F8WT was excellent; ICC2,1=0.95(0.91~0.97), acceptable SEM=1.02, and SRD=2.82. F8WT were also found to be significantly associated with PASS(r=-0.82) and TIS(r=-0.85). Therefore, F8WT is a reliable measurement tool and is correlated well with stroke-impairments, such as postural and trunk control. F8WT will be a useful tool in evaluating the walking performance of subjects with chronic stroke.
