Abstract：
BACKGROUND: Cervical spondylotic myelopathy (CSM) is the most common degenerative dysfunction of the spinal cord in the cervical spine in patients older than 55 years. The Japanese Orthopedic Association developed a scoring system to quantify clinical impairment of CSM patients, allocate them according to the degree of impairment, and suggest best timing for surgery. The original version evaluates the upper limb motor function through the ability of feeding with chopsticks, which are not intrinsic in western populations. To compare severity and treatment improvement of any diseases, it is preferable to have modified and translated versions of questionnaires and scores closest to the original ones. The authors present a prospective cohort study to validate the 17-point Brazilian Portuguese translated version of the modified Japanese Orthopedic Association (mJOA-BR17) survey.
METHODS: Patients with CSM (n = 36) were allocated to the disease group, while age- and sex-matched healthy volunteers (n = 34) were recruited for the control group. Comparison of statistical analysis of mJOA-BR17 domains for each group was established. After the translation and adaptation of mJOA-BR17, the validation was made through application to the 2 groups.
RESULTS: There were statistical differences between groups in total mJOA-BR17 score (CSM, 14.14 ± 2.92; control, 16.68 ± 0.59: P < 0.001), lower limbs motor function (CSM, 3.25 ± 1.02; control, 3.91 ± 0.29: P < 0.001), upper limbs sensory function (CSM, 1.17 ± 0.81; control, 1.86 ± 0.36: P < 0.001), lower limbs sensory function (CSM, 1.62 ± 0.64; control, 2.0 ± 0.0: P < 0.001), and bladder function (CSM, 2.69 ± 0.52; control, 2.97 ± 0.17: P = 0.005). The receiver operating characteristic curve was 0.81, indicating usefulness of the mJOA-BR17 score to identify patients with CSM from healthy controls.
CONCLUSIONS: The mJOA-BR17 demonstrated similarity, applicability, and good understanding in comparison to the English-modified version of 17-point JOA score for CSM, becoming a valuable tool to quantify and differentiate CSM patients from healthy individuals.

摘要：
背景：脊髓型颈椎病（CSM）是55岁以上患者中最常见的颈椎脊髓退行性功能障碍。日本骨科协会开发了一个评分系统来量化CSM患者的临床损伤，根据减值程度分配，并建议手术的最佳时机。原始版本通过用筷子喂食的能力来评估上肢运动功能，这在西方人口中不是固有的。为了比较任何疾病的严重程度和治疗改善，最好是修改和翻译问卷的版本以及与原始问卷最接近的分数。作者提出了一项前瞻性队列研究，以验证经修改的日本骨科协会（mJOA-BR17）调查的17点巴西葡萄牙语翻译版本。
方法：将患有CSM的患者（n=36）分配到疾病组，而年龄和性别匹配的健康志愿者（n=34）被招募为对照组。建立每组mJOA-BR17结构域的统计学分析比较。在mJOA-BR17的翻译和改编后，通过应用于2组进行验证。
结果：mJOA-BR17总分在组间有统计学差异（CSM，14.14±2.92；对照，16.68±0.59：P<0.001），下肢运动功能(CSM，3.25±1.02;对照,3.91±0.29：P<0.001），上肢感觉功能(CSM，1.17±0.81；对照，1.86±0.36：P<0.001），下肢感觉功能(CSM，1.62±0.64；对照，2.0±0.0：P<0.001），和膀胱功能(CSM，2.69±0.52；对照，2.97±0.17：P=0.005）。受试者工作特征曲线为0.81，表明mJOA-BR17评分可用于从健康对照中识别CSM患者。
结论：mJOA-BR17表现出相似性，适用性,与CSM的17分JOA分数的英文修改版相比，理解得很好，成为量化和区分CSM患者与健康个体的有价值的工具。
