The current study was designed to assess interrater and intrarater validity of cervical range of motion measurements performed with a CROM goniometer. The study involved 95 healthy university students (31 males and 64 females) aged 20-24 years. Two examiners performed measurements of cervical range of motion using a CROM goniometer. The same subjects were examined again after two weeks, in the same conditions. The results acquired by one rater during the first and the second examination were compared for reproducibility, while the results obtained by the two examiners were compared to assess validity and reliability of the tool. Cronbach's alpha was applied to determine intrarater reliability, and the values of correlations were used to assess the interrater agreement.
Analysis of the results showed both intrarater and interrater agreement in all the measures of cervical range of motion. The highest intrarater and interrater concordance was observed in the measure of extension. Intrarater agreement for Examiner 1 was reflected by Cronbach's alpha = 0.85, and for Examiner 2 by Cronbach's alpha = 0.89. As for the interrater agreement in the measure of extension, the value of correlation in both the first and the second measurement amounted to = 0.89.
Measurements performed with the CROM goniometer show interrater and intrarater agreement in assessments of cervical range of motion. The CROM goniometer can be recommended for use in daily clinical practice.
本研究旨在评估 CROM 量角器测量颈椎活动度的组内和组间信度。研究纳入了 95 名年龄在 20-24 岁的健康大学生（31 名男性和 64 名女性）。两名检查者使用 CROM 量角器测量颈椎活动度。两周后，在相同条件下对同一受试者进行了再次检查。一位评估者在第一次和第二次检查期间获得的结果进行了比较，以评估其可重复性，而两位评估者的结果则用于评估该工具的有效性和可靠性。Cronbach's alpha 用于确定组内信度，而相关系数值用于评估组间一致性。
对结果的分析表明，在所有颈椎活动度测量中均存在组内和组间的一致性。在伸展测量中观察到了最高的组内和组间一致性。评估者 1 的组内信度用 Cronbach's alpha 表示为 0.85，评估者 2 的组内信度用 Cronbach's alpha 表示为 0.89。就伸展测量的组间一致性而言，在第一次和第二次测量中，相关系数值均为 = 0.89。
使用 CROM 量角器进行的测量在评估颈椎活动度方面具有组内和组间的一致性。CROM 量角器可推荐在日常临床实践中使用。
