To develop an observational gait analysis tool for children with Down syndrome and to examine its reliability.
Two physical therapists and 5 physical therapy students participated in this study. Sixty videos were examined to determine interrater reliability. Four months later, 15 of those 60 videos were reexamined twice (2 weeks apart) by the students for intrarater reliability. Intraclass correlation coefficients for interrater and intrarater reliability, percentage of agreement, and standard error of measurement were calculated.
Interrater reliability was 0.663, intrarater reliability was 0.616-0.877, standard error of measurement was 1.89, and absolute agreement was found for 35.56% of the trials.
Good reliability was found, but further study is needed to determine validity and clinical relevance.
开发一种针对唐氏综合征儿童的观察性步态分析工具，并检验其可靠性。
两名物理治疗师和五名物理治疗专业学生参与了本研究。检查了60个视频以确定评分者间信度。四个月后，学生们对这60个视频中的15个进行了两次重新检查（间隔两周），以确定评分者内信度。计算了评分者间和评分者内信度的组内相关系数、一致率和测量标准误。
评分者间信度为0.663，评分者内信度为0.616 - 0.877，测量标准误为1.89，35.56%的试验结果完全一致。
发现该工具具有良好的信度，但需要进一步研究以确定其效度和临床相关性。
