To compare walking efficiency, and associated physical function, between children, with and without developmental coordination disorder trait.
Cross-sectional study.
The study was conducted in a Medical and Rehabilitation Center for Developmental Disabilities in Okazaki, Japan.
The study included 286 children, 6-12 years of age, with and without developmental coordination disorder trait. Developmental coordination disorder trait was defined by a score below the -1 standard deviation on the Japanese version of the Developmental Coordination Disorder Questionnaire. Based on this criterion, 45 children (28 boys) were classified into the developmental coordination disorder trait group and the other 241 (115 boys) in the control group.
The following physical function outcomes were measured: single leg stance test; step length variability; and walking efficiency, measured using the 2-min walk test. Logistic regression analysis was used to determine the association between developmental coordination disorder trait and lower walking efficiency and physical function.
Compared to the control group, the developmental coordination disorder group showed lower walking efficiency ( = 0.026), higher step length variability ( = 0.047), and shorter single leg stance test ( = 0.001). Developmental coordination disorder was independently associated with walking efficiency (odds ratio, 1.03; 95% confidence interval [CI], 1.001-1.061; = 0.041) and single leg stance test (odds ratio, 0.99; 95% CI, 0.978-0.996; = 0.006), but not to step length variability, age, and sex.
Lower walking efficiency increases energy expenditure in children with developmental coordination disorder trait. Interventions to improve walking efficiency could improve the physical function and participation of these children.
比较患有和不患有发展性协调障碍特质的儿童的步行效率及其相关的身体功能。
横断面研究。
该研究在日本冈崎市的一家发育障碍医学康复中心进行。
该研究纳入了 286 名 6-12 岁的儿童，其中包括患有和不患有发展性协调障碍特质的儿童。发展性协调障碍特质是通过日本版发展性协调障碍问卷的得分低于-1 个标准差来定义的。根据这一标准，45 名儿童（28 名男孩）被归入发展性协调障碍特质组，而其他 241 名儿童（115 名男孩）归入对照组。
测量以下身体功能结果：单腿站立测试；步长变异性；以及使用 2 分钟步行测试测量的步行效率。采用逻辑回归分析确定发展性协调障碍特质与较低的步行效率和身体功能之间的关系。
与对照组相比，发展性协调障碍组的步行效率较低（ = 0.026），步长变异性较高（ = 0.047），单腿站立测试时间较短（ = 0.001）。发展性协调障碍特质与步行效率（优势比，1.03；95%置信区间[CI]，1.001-1.061； = 0.041）和单腿站立测试（优势比，0.99；95% CI，0.978-0.996； = 0.006）独立相关，但与步长变异性、年龄和性别无关。
发展性协调障碍特质儿童步行效率较低会增加能量消耗。提高步行效率的干预措施可以改善这些儿童的身体功能和参与度。
