RATIONALE
As primary care practice space is mostly limited to 10 m, the 6-minute walk test (6MWT) over a 10 m course is a frequently used alternative to evaluate patients' performance in COPD. Considering that course length significantly affects distance walked in 6 minutes (6MWD), this study aims to develop appropriate reference equations for the 10 m 6MWT.
METHODS
181 healthy subjects, aged 40-90 years, performed two standardised 6MWTs over a straight 10 m course in a cross-sectional study.
RESULTS
Average distance achieved was 578±108 m and differed between males and females (p<0.001). Resulting sex-specific reference equations from multiple regression analysis included age, body mass index and change in heart rate, explaining 62% of the variance in 6MWD for males and 71% for females.
CONCLUSIONS
The presented reference equations are the first to evaluate 6MWD over a 10 m course and expand the usefulness of the 6MWT.
背景
由于初级保健实践空间主要限于 10 米，因此，在 10 米的路程上进行 6 分钟步行测试（6MWT）是评估 COPD 患者表现的常用替代方法。考虑到路程长度会显著影响 6 分钟内行走的距离（6MWD），本研究旨在为 10 米 6MWT 制定适当的参考方程。
方法
在一项横断面研究中，181 名年龄在 40-90 岁的健康受试者在一条笔直的 10 米路线上进行了两次标准化的 6MWT。
结果
平均距离为 578±108 m，男女之间存在差异（p<0.001）。多变量回归分析得出的性别特异性参考方程包括年龄、体重指数和心率变化，解释了男性 6MWD 变异性的 62%，女性为 71%。
结论
本研究提出的参考方程是首次评估 10 米路程上的 6MWD，扩展了 6MWT 的用途。
