PURPOSE
To establish intrarater and interrater reliability of still photography for measuring habitual head deviation from midline in infants with congenital muscular torticollis (CMT).
METHODS
Two investigators took still photographs of 30 infants with CMT in a supine position and measured head deviation angles with a protractor. Data analysis included paired t tests, Pearson r, and intraclass correlation coefficients (ICC) with 95% confidence intervals.
RESULTS
Pearson r varied from 0.80 to 0.85 for the same rater and from 0.72 to 0.99 for 2 different raters. The ICC (3,1) varied from 0.79 to 0.84, and ICC (2,1) varied from 0.72 to 0.99. Participants with smaller head-tilt angles showed greater variability in head position.
CONCLUSIONS
Still photography is a reliable method for measuring habitual head deviation from midline in infants with CMT. Several modifications to the measurement procedure have been suggested.
目的
建立在测量先天性肌性斜颈（CMT）婴儿习惯性头部偏离中线时静态摄影的同一评估者和不同评估者间的可靠性。
方法
两名研究者对30名CMT婴儿仰卧位进行静态摄影，并用角度量角器测量头部偏斜角度。数据分析包括配对t检验、Pearson相关系数r和具有95%置信区间的组内相关系数（ICC）。
结果
同一评估者的Pearson相关系数r在0.80至0.85之间，两名不同评估者的Pearson相关系数r在0.72至0.99之间。ICC（3,1）在0.79至0.84之间，ICC（2,1）在0.72至0.99之间。头部倾斜角度较小的参与者头部位置的变异性更大。
结论
静态摄影是测量CMT婴儿习惯性头部偏离中线的可靠方法。已对测量程序提出了一些改进建议。
