To evaluate interrater reliability and concurrent validity of the 50-ft walk test (FWT) for children with idiopathic toe walking (ITW).
Thirty children, 6 to 13 years old, with ITW participated. During the 50-FWT, an accelerometer counted total steps. A physical therapist counted the number of toe-walking steps. The number of toe-walking steps was divided by the total steps to calculate a toe-walking percentage. Interrater reliability was assessed by correlating the toe-walking percentage obtained by 2 raters using an intraclass correlation coefficient. Concurrent validity was evaluated by correlating the toe-walking percentage calculated by the GAITRite and therapist using a Spearman ρ.
There was excellent interrater reliability and concurrent validity. Experience level did not impact the therapist's ability to identify a toe-walking step.
The 50-FWT demonstrated excellent interrater reliability and concurrent validity. It can be used to obtain a percentage of toe walking in children 6-13 years of age with ITW.
评估50英尺步行测试（FWT）在特发性足尖行走（ITW）儿童中的评分者间信度和同时效度。
30名6至13岁的ITW儿童参与。在50英尺步行测试期间，一个加速度计计算总步数。一名物理治疗师计算足尖行走步数。足尖行走步数除以总步数来计算足尖行走百分比。通过使用组内相关系数使两名评分者获得的足尖行走百分比相关来评估评分者间信度。通过使用Spearman ρ使GAITRite和治疗师计算的足尖行走百分比相关来评估同时效度。
存在出色的评分者间信度和同时效度。经验水平并未影响治疗师识别足尖行走步数的能力。
50英尺步行测试显示出出色的评分者间信度和同时效度。它可用于得出6至13岁ITW儿童的足尖行走百分比。
