We investigated the feasibility and construct validity of the Dynamic Gait Index (DGI) in children and explored interrater and test-retest reliability.
DGI performance of 10 children with fetal alcohol spectrum disorder (FASD), aged 8 to 15 years, was compared with that of 10 age- and sex-matched children with typical development (TD). Interrater reliability was evaluated for 16 children (10 TD, 6 FASD); 11 children returned for a retest (5 TD, 6 FASD).
The DGI is simple for raters to learn and easy to administer in children. A Mann-Whitney U test identified a significant difference on the DGI total score between children with FASD and TD (P = .01). Interrater and test-retest reliability were promising but need to be further explored.
The DGI was feasible and valid in a population of children aged 8 to 15 years with FASD and TD. Some modifications are suggested for administration of the DGI in children.
我们研究了动态步态指数（DGI）在儿童中的可行性和结构效度，并探讨了评分者间信度和重测信度。
将10名8至15岁患有胎儿酒精谱系障碍（FASD）的儿童的DGI表现与10名年龄和性别匹配的发育正常（TD）儿童的DGI表现进行比较。对16名儿童（10名TD，6名FASD）评估评分者间信度；11名儿童返回进行重测（5名TD，6名FASD）。
评分者学习DGI很简单，且该测试在儿童中易于实施。曼-惠特尼U检验发现FASD儿童和TD儿童在DGI总分上存在显著差异（P = 0.01）。评分者间信度和重测信度前景良好，但需要进一步探索。
DGI在8至15岁患有FASD和TD的儿童群体中是可行且有效的。建议对儿童实施DGI进行一些修改。
