The aim of the present study was to evaluate the reliability of the Cartesian Optoelectronic Dynamic Anthropometer (CODA) motion system in measuring the cervical range of motion (ROM) and verify the construct validity of the CODA motion system. A total of 26 patients with cervical spondylosis and 22 patients with anterior cervical fusion were enrolled and the CODA motion analysis system was used to measure the three-dimensional cervical ROM. Intra- and inter-rater reliability was assessed by interclass correlation coefficients (ICCs), standard error of measurement (SEm), Limits of Agreements (LOA) and minimal detectable change (MDC). Independent samples t-tests were performed to examine the differences of cervical ROM between cervical spondylosis and anterior cervical fusion patients. The results revealed that in the cervical spondylosis group, the reliability was almost perfect (intra-rater reliability: ICC, 0.87-0.95; LOA, -12.86-13.70; SEm, 2.97-4.58; inter-rater reliability: ICC, 0.84-0.95; LOA, -13.09-13.48; SEm, 3.13-4.32). In the anterior cervical fusion group, the reliability was high (intra-rater reliability: ICC, 0.88-0.97; LOA, -10.65-11.08; SEm, 2.10-3.77; inter-rater reliability: ICC, 0.86-0.96; LOA, -10.91-13.66; SEm, 2.20-4.45). The cervical ROM in the cervical spondylosis group was significantly higher than that in the anterior cervical fusion group in all directions except for left rotation. In conclusion, the CODA motion analysis system is highly reliable in measuring cervical ROM and the construct validity was verified, as the system was sufficiently sensitive to distinguish between the cervical spondylosis and anterior cervical fusion groups based on their ROM.
本研究的目的是评估笛卡尔光电动态人体测量仪（CODA）运动系统在测量颈椎活动范围（ROM）方面的可靠性，并验证CODA运动系统的结构效度。共纳入26例颈椎病患者和22例颈椎前路融合术患者，使用CODA运动分析系统测量颈椎三维活动范围。通过组内相关系数（ICC）、测量标准误差（SEm）、一致性界限（LOA）和最小可检测变化（MDC）评估评分者内和评分者间的可靠性。进行独立样本t检验以检查颈椎病患者和颈椎前路融合术患者之间颈椎活动范围的差异。结果显示，在颈椎病组中，可靠性几乎完美（评分者内可靠性：ICC，0.87 - 0.95；LOA，-12.86 - 13.70；SEm，2.97 - 4.58；评分者间可靠性：ICC，0.84 - 0.95；LOA，-13.09 - 13.48；SEm，3.13 - 4.32）。在颈椎前路融合术组中，可靠性较高（评分者内可靠性：ICC，0.88 - 0.97；LOA，-10.65 - 11.08；SEm，2.10 - 3.77；评分者间可靠性：ICC，0.86 - 0.96；LOA，-10.91 - 13.66；SEm，2.20 - 4.45）。除左旋外，颈椎病组在所有方向上的颈椎活动范围均显著高于颈椎前路融合术组。总之，CODA运动分析系统在测量颈椎活动范围方面具有高度可靠性，并且验证了其结构效度，因为该系统能够根据活动范围充分敏感地区分颈椎病组和颈椎前路融合术组。
