Gait speed and walking distance were evaluated as predictors for levels of community walking after stroke. In this study, 103 stroke survivors were identified as limited (n = 67) or independent community walkers (n = 36). Ten meter and six min walk tests were used to measure gait speed and walking distance, respectively. The discriminative properties of gait speed and walking distance for community walking were investigated using receiver operating characteristic curves. Cut-off values of 0.87 m/s for community walking gait speed for walking distance had positive predictive values of 65% and 55%, respectively. The negative predictive value ranged from 89% for gait speed to 79% for walking distance. Gait speed and walking distance showed significant differences between limited and independent community walking. Gait speed was more significantly related to community walking than walking distance. The results of this study suggest that gait speed is a better predictor for community walking than walking distance in moderately affected post-stroke survivors.
步态速度和步行距离被评估为中风后社区步行水平的预测指标。在本研究中,103名中风幸存者被确定为社区步行受限者(n = 67)或独立社区步行者(n = 36)。分别采用10米步行试验和6分钟步行试验来测量步态速度和步行距离。使用受试者工作特征曲线研究步态速度和步行距离对社区步行的判别特性。社区步行步态速度的截止值为0.87米/秒,步行距离的截止值分别具有65%和55%的阳性预测值。阴性预测值范围从步态速度的89%到步行距离的79%。社区步行受限者和独立社区步行者之间的步态速度和步行距离存在显著差异。步态速度比步行距离与社区步行的相关性更强。本研究结果表明,在中度受影响的中风后幸存者中,步态速度比步行距离更能预测社区步行情况。
