Goniometric finger range of motion (ROM) is the most common outcome measure used for functional evaluation of finger joints, but its reliability is not well-evaluated. This study aimed to investigate intra- and inter-rater reliability of goniometric finger ROM using a written protocol for active, passive, and composite movements in healthy adults.
The design was a single-center, cross-sectional, reliability study. Participants were 20 healthy adults (mean ± standard deviation, 36.4 ± 10.9 years). ROM for active, passive, and composite movements of the fingers was assessed by three occupational therapists with at least 5 years clinical experience in the field of physical disabilities. To standardize the measurement method used, we developed a written protocol, stabilized the wrist position, and trained the evaluators. Intraclass correlation coefficient (ICC) values were used for the reliability analysis. ICC (1,1) was used for intra-rater reliability. ICC (2,1) was used for inter-rater reliability. Hand-shaped heatmaps were used to summarize the reliability data.
Most of the results (88.7%) showed moderate to good intra-rater reliability (ICC ≥ 0.50), while inter-rater reliability showed less (69.0%). Both intra- and inter-rater reliability showed no trends between dominant and non-dominant hands, type of movement, finger, or joint.
Intra-rater reliability was relatively high and using a written protocol was beneficial. Inter-rater reliability tended to be lower, and differences in the physical structure of both raters and participants may have affected inter-rater reliability values.
测角法测量的手指活动范围（ROM）是用于手指关节功能评估最常用的结果指标，但其可靠性尚未得到充分评估。本研究旨在通过一份针对健康成年人主动、被动和复合运动的书面方案，调查测角法测量手指ROM的评估者内和评估者间可靠性。
本研究为单中心横断面可靠性研究。参与者为20名健康成年人（平均±标准差，36.4±10.9岁）。由三名在肢体残疾领域至少有5年临床经验的职业治疗师评估手指主动、被动和复合运动的ROM。为规范所使用的测量方法，我们制定了一份书面方案，稳定手腕位置，并对评估者进行培训。采用组内相关系数（ICC）值进行可靠性分析。ICC（1,1）用于评估者内可靠性分析。ICC（2,1）用于评估者间可靠性分析。使用手部热图总结可靠性数据。
大多数结果（88.7%）显示评估者内可靠性为中度至良好（ICC≥0.50），而评估者间可靠性较低（69.0%）。评估者内和评估者间可靠性在优势手与非优势手、运动类型、手指或关节之间均无趋势差异。
评估者内可靠性相对较高，使用书面方案有益。评估者间可靠性往往较低，评估者和参与者身体结构的差异可能影响了评估者间可靠性值。
