Reliability and agreement of goniometric measurements can be altered by variations in measurement technique such as restricting adjacent joints to influence bi-articular muscles. It is unknown if the influence of adjacent joint restriction is consistent across different range of motion (ROM) tests, as this has yet to be assessed within a single study. Additionally, between-study comparisons are challenged by differences between methodology, participants and raters, obscuring the development of a conceptual understanding of the extent to which adjacent joint restriction can influence goniometric ROM measurements.
To quantify intra- and inter-rater reliability and levels of agreement of goniometric measurements across five ROM tests, with and without adjacent joint restriction.
Descriptive reliability study.
Three trained and experienced raters made two measurements of bilateral ankle dorsiflexion, first metatarsophalangeal dorsiflexion, hip extension, hip flexion, and shoulder flexion, with and without adjacent joint restriction. Intraclass correlation coefficient (ICC), standard error of measurement (SEM), along with participant, measurement/rater and random error variance were estimated.
Eleven females (age 21.4 ±2.3 years) and 19 males (age 22.1 ±2.8 years) participated. Adjacent joint restriction did not influence the reliability and agreement in a consistent way across the five ROM tests. Changes in the inter-rater reliability and agreement were more pronounced compared to the intra-rater reliability and agreement. Assessing variance components (participant, measurement/rater and random error variance) that are used to calculate the ICC and SEM, improved interpretation of ICC and SEM scores.
The effects of adjacent joint restriction on reliability and agreement of goniometric measurements depend on the ROM test and should be considered when comparing measurements between multiple raters. Reporting variance components that are used to calculate the ICC and SEM can improve interpretation and may improve between-study comparisons, towards developing a conceptual framework to guide goniometric measurement technique.

测角测量的可靠性和一致性可能会因测量技术的变化而改变，例如限制相邻关节以影响双关节肌肉。相邻关节限制的影响在不同的关节活动范围（ROM）测试中是否一致尚不清楚，因为这尚未在一项研究中进行评估。此外，研究间的比较受到方法、参与者和评估者之间差异的挑战，这使得难以形成对相邻关节限制在多大程度上会影响测角ROM测量的概念性理解。
量化在有和没有相邻关节限制的情况下，五项ROM测试中测角测量的评分者内和评分者间可靠性以及一致性水平。
描述性可靠性研究。
三名经过培训且经验丰富的评估者对双侧踝关节背屈、第一跖趾关节背屈、髋关节伸展、髋关节屈曲和肩关节屈曲进行了两次测量，分别在有和没有相邻关节限制的情况下进行。估计了组内相关系数（ICC）、测量标准误差（SEM）以及参与者、测量/评估者和随机误差方差。
11名女性（年龄21.4±2.3岁）和19名男性（年龄22.1±2.8岁）参与了研究。在五项ROM测试中，相邻关节限制并没有以一致的方式影响可靠性和一致性。与评分者内可靠性和一致性相比，评分者间可靠性和一致性的变化更为明显。评估用于计算ICC和SEM的方差成分（参与者、测量/评估者和随机误差方差），有助于更好地解释ICC和SEM分数。
相邻关节限制对测角测量可靠性和一致性的影响取决于ROM测试，在比较多个评估者的测量结果时应予以考虑。报告用于计算ICC和SEM的方差成分可以改善解释，并可能改善研究间的比较，从而形成一个指导测角测量技术的概念框架。
