In a modification of conventional walking tests in respiratory disease patients were asked to walk successive 50 m lengths of a corridor and the time taken over the third 100 m was taken as the walking pace. This pace was highly correlated (r = 0.994) with the 12-minute distance and was highly reproducible (r = 0.98).
在对传统步行测试的一项改进中，要求呼吸系统疾病患者在走廊上连续走完50米的长度，并将走完第三个100米所需的时间作为步行速度。这个速度与12分钟步行距离高度相关（r = 0.994），并且具有高度的可重复性（r = 0.98）。
