[Purpose] To examine the reliability of using a manual goniometer for measuring the range of dart-throwing motion. [Participants and Methods] The range of dart-throwing motion in 24 healthy participants was measured by three raters on the same day, and one rater repeated the measurement on another day of the same week. The stationary arm of the goniometer was placed along the radius, and the moveable arm was placed along the shaft of the second metacarpal, approximately 45° supinated from Lister's tubercle. All of the participants performed the dart-throwing motion on a plane that passed through the anatomical neutral wrist position, inclined 45° to the orthogonal anatomical plane. [Results] The intra-rater reliability was moderate (0.5-0.75) only for some parameters of the radial extension, and the intraclass correlation coefficients (ICCs) of all other parameters were <0.5. For the inter-rater reliability, the ICCs of all parameters were <0.5. Brand-Altman analysis revealed some fixed biases between the raters, although no proportional bias was observed. [Conclusion] The goniometric measurement procedure examined in this study appeared to be unsuitable for clinical use because of its poor reliability.
[目的] 检验使用手动测角仪测量掷飞镖动作范围的可靠性。[参与者与方法] 24名健康参与者的掷飞镖动作范围由三名评估者在同一天进行测量，且一名评估者在同一周的另一天重复测量。测角仪的固定臂沿桡骨放置，活动臂沿第二掌骨轴放置，从Lister结节处旋后约45°。所有参与者在一个穿过解剖学中立腕关节位置、与正交解剖平面成45°倾斜的平面上进行掷飞镖动作。[结果] 仅桡侧伸展的某些参数的评估者内信度为中等（0.5 - 0.75），所有其他参数的组内相关系数（ICC）均<0.5。对于评估者间信度，所有参数的ICC均<0.5。Bland - Altman分析显示评估者之间存在一些固定偏差，尽管未观察到比例偏差。[结论] 本研究中所检验的测角测量程序可靠性较差，似乎不适用于临床。
