The modified Japanese orthopaedic association scale (mJOA) is considered one of the most appropriate outcome measures for the assessment of cervical spondylotic myelopathy (CSM). Moreover, mJOA has been recognised among the key predictors of surgical outcome at a global level. To apply the mJOA successfully at an international level, it should be translated and culturally adapted in the native language of the investigators using this scale. A translated version of the mJOA or any other functional scale has never been studied within an Italian population affected by CSM. The aim of this study has been to describe translation, cultural adaptation and psychometric properties of the Italian version of the mJOA (mJOA-IT).
The mJOA-IT was developed following a forward-backward translation procedure. Psychometric properties were assessed on a cohort of patients with CSM undergone anterior or posterior decompression associated with stabilisation in lordosis.
The mJOA-IT proved to be a reliable outcome measure for CSM (internal consistency 0.60, test-retest stability 0.910, P < 0.001, inter-observer reliability 0.80, P < 0.001). The mJOA-IT was associated with the Nurick scale (r = -0.615) while it was not associated with NDI, SF-36 and SF-36 components. The mJOA-IT was also responsive (d = 0.867).
The mJOA-IT proved to be a reliable and valid tool to assess patients affected by CSM. This form is recommended to be used for clinical and research purposes in Italy, to promote the global standardisation of assessment tools and to compare studies on CSM worldwide.
改良日本骨科协会量表（mJOA）被认为是评估脊髓型颈椎病（CSM）最合适的疗效指标之一。此外，mJOA在全球范围内已被公认为手术疗效的关键预测指标之一。为了在国际层面成功应用mJOA，应将其翻译成研究人员所在国家的母语并进行文化调适。mJOA或任何其他功能量表的翻译版本从未在受CSM影响的意大利人群中进行过研究。本研究的目的是描述意大利版mJOA（mJOA-IT）的翻译、文化调适及心理测量特性。
mJOA-IT通过正向-反向翻译程序制定。对一组接受前路或后路减压并伴有前凸稳定术的CSM患者评估其心理测量特性。
mJOA-IT被证明是一种用于CSM的可靠疗效指标（内部一致性0.60，重测稳定性0.910，P<0.001，观察者间信度0.80，P<0.001）。mJOA-IT与Nurick量表相关（r=-0.615），而与NDI、SF-36及其各分量表无关。mJOA-IT也具有反应性（d=0.867）。
mJOA-IT被证明是评估CSM患者的可靠且有效的工具。建议在意大利将此量表用于临床和研究目的，以促进评估工具的全球标准化，并比较全球范围内关于CSM的研究。
