The 6-minute walk test (6MWT) in children can be performed in the conventional way, or by using a measuring wheel. This study aimed to compare these test modalities and to determine influencing factors.
The study included 317 healthy children (172 boys) between 6 and 15 years from elementary schools and high schools, who were randomly assigned to perform a 6MWT either with or without a measuring wheel according to the guidelines of the American Thoracic Society. The 6-minute walk distance (6MWD) was compared between the two measuring modalities as well as different school types.
The use of a measuring wheel during the 6MWT led to a significantly greater 6MWD compared to conventional walking. Students of sports schools walked substantially farther than those attending general high schools, irrespective of test modality. In multivariate regression analysis height, post-test heart rate, male sex and the measuring wheel itself were all independently associated with greater 6MWD.
The use of a measuring wheel during a 6MWT reflects physical performance in children and adolescents more accurately as it includes the stretch of way around the cones during lap turns. Test modalities and sports background should be taken into account, especially when performing longitudinal monitoring and multicenter studies.
儿童6分钟步行试验（6MWT）可以采用传统方式进行，也可以使用测量轮进行。本研究旨在比较这两种测试方式并确定影响因素。
该研究纳入了317名6至15岁来自小学和高中的健康儿童（172名男孩），他们根据美国胸科学会的指南被随机分配使用或不使用测量轮进行6MWT。比较了两种测量方式以及不同学校类型之间的6分钟步行距离（6MWD）。
与传统步行相比，在6MWT期间使用测量轮导致6MWD显著增加。体育学校的学生无论测试方式如何，都比普通高中的学生走得更远。在多变量回归分析中，身高、测试后心率、男性性别和测量轮本身均与更大的6MWD独立相关。
在6MWT期间使用测量轮能更准确地反映儿童和青少年的身体表现，因为它包括了在折返转弯时绕过锥体的路程延伸。在进行纵向监测和多中心研究时，应考虑测试方式和体育背景。
