日本骨科协会 (JOA) 评分广泛用于评估颈椎压迫性脊髓病患者临床症状的严重程度，特别是在东亚国家。相比之下，JOA评分的修改版本目前被西方国家接受为评估的标准工具。本研究的目的是比较这些量表，阐明它们的差异和互换性，并通过将它们与其他结果测量进行比较来验证它们的有效性。五家机构参与了这项前瞻性多中心观察研究。 Benzel 提出的 JOA 和改良 JOA (mJOA) 记录了接受减压手术的颈椎压迫性脊髓病患者的术前和术后三个月。还记录了患者报告的结果 (PRO) 指标，包括日本骨科协会颈髓病评估问卷 (JOACMEQ)、简表 12 (SF-12) 和颈部残疾指数 (NDI)。将术前 JOA 评分和 mJOA 评分相互比较以及 PRO 值进行比较。进行布兰德-奥特曼分析来调查他们的一致性极限。总共包括九十二名患者。 JOA 和 mJOA 之间的相关系数 (Spearman’s rho) 为 0.87。相反，JOA/mJOA 与其他 PRO 值之间的相关性适中 (|rho| = 0.03 – 0.51)。 JOA和mJOA恢复率的相关系数为0.75。 Bland-Altman 分析显示，总分的一致限度为 3.6 至 -1.2，恢复率的一致限度为 55.1% 至 -68.8%。在本研究中，JOA评分和mJOA评分在总分和恢复率方面表现出良好的相关性。之前使用 JOA 的研究可以基于 mJOA 进行解释；然而，互换使用它们并不理想。通过将这些值与 PRO 值进行比较，证明了这两个分数的有效性。
The Japanese Orthopaedic Association (JOA) score is widely used to assess the severity of clinical symptoms in patients with cervical compressive myelopathy, particularly in East Asian countries. In contrast, modified versions of the JOA score are currently accepted as the standard tool for assessment in Western countries. The objective of the present study is to compare these scales and clarify their differences and interchangeability and verify their validity by comparing them to other outcome measures. Five institutions participated in this prospective multicenter observational study. The JOA and modified JOA (mJOA) proposed by Benzel were recorded preoperatively and at three months postoperatively in patients with cervical compressive myelopathy who underwent decompression surgery. Patient reported outcome (PRO) measures, including Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ), the Short Form-12 (SF-12) and the Neck Disability Index (NDI), were also recorded. The preoperative JOA score and mJOA score were compared to each other and the PRO values. A Bland-Altman analysis was performed to investigate their limits of agreement. A total of ninety-two patients were included. The correlation coefficient (Spearman’s rho) between the JOA and mJOA was 0.87. In contrast, the correlations between JOA/mJOA and the other PRO values were moderate (|rho| = 0.03 – 0.51). The correlation coefficient of the recovery rate between the JOA and mJOA was 0.75. The Bland-Altman analyses showed that limits of agreement were 3.6 to -1.2 for the total score, and 55.1% to -68.8% for the recovery rates. In the present study, the JOA score and the mJOA score showed good correlation with each other in terms of their total scores and recovery rates. Previous studies using the JOA can be interpreted based on the mJOA; however it is not ideal to use them interchangeably. The validity of both scores was demonstrated by comparing these values to the PRO values.
