Abstract: Study investigated the intra-rater, inter-rater, and test-retest reliabilities of the Figure-of-Eight Walk (F8W) test; its correlation with other stroke-specific impairments; and the cut-off scores best discriminating patients with stroke from healthy older adults. Thirty-five subjects with chronic stroke and 29 healthy elderly subjects participated in the study. Outcome measures included: F8W test times, Fugl-Meyer Motor Assessment for the lower extremities (FMA-LE), hand-held dynamometer measurements of bilateral hip abductor and knee extensor isometric muscle strength, Five times Sit to Stand Test (FTSTST) times, 10-Meter Walk Test (10MWT), Timed Up and Go Test (TUG) times, Berg Balance Scale (BBS), and Activities-specific Balance Confidence Scale (ABC) scores. Excellent intra-rater, inter-rater and test-retest reliabilities (intra-class correlation coefficients = 0.944 to 0.999) of F8W test times were found. The F8W test times were also found to be significantly associated with FMA-LE, BBS, FTSTST, TUG scores and 10MWT. No significant correlation was found between F8W test times and either leg strength or ABC results. A F8W test time of 8.2 seconds was found to be the most representative for discriminating between healthy elderly and stroke subjects, with a sensitivity of 100 percent and a specificity of 89.7 percent. Results suggest that the F8W test time is a reliable measurement tool for assessing the advanced walking performance of subjects with chronic stroke. The F8W was able to differentiate between patients with stroke and healthy elderly subjects and correlated well with stroke-specific impairments and walking tests.
