Abstract

Background and Objective: Cervical myelopathy population (CMP) is a common cause of significant clinical morbidity. This study aimed to translate and validate the modified Japanese Orthopedic Association score (mJOA) English version in Iran.

Material and Methods: This was a prospective clinical validation study. Psychometric properties of the questionnaire were assessed using internal consistency; inter-observer reliability, discriminant validity, and responsive ness of the questionnaire to change.

Results: A total of 63 patients were studied. The mean mJOA score was 9.82 (SD = 1.0). Internal consistency of the mJOA as measured by Cronbach’s alpha coefficient was satisfactory (alpha = 0.77). Inter-observer agreement as measured by Kappa statistics also was found to be acceptable (0.75). Known-groups comparison was performed to test discriminant validity and the findings indicated that the mJOA was able to differentiate between males and females and different age groups as expected (P < 0.0001). Finally the questionnaire was found to be responsive to change as patients’ pre- and post-operative scores on the mJOA (P < 0.0001).

Conclusion: The Iranian version of mJOA performed well and the findings suggest that it is a reliable and valid measure of motor, sensory and sphincter dysfunctions among CMP patients.
