AB  - INTRODUCTION: Degenerative Cervical Myelopathy (DCM) is a growing disorder. 
      Standardization of its assessment tools is an integral part of its management. 
      The modified Japanese orthopedic association (mJOA) score is one of the most 
      commonly used tools. Currently, there is no available Arabic translated version 
      of any cervical myelopathy functional score. This study aimed to translate, 
      culturally adapt, and measure the psychometric properties of an Arabic translated 
      version of the mJOA. METHODS: After translation of the score using the standard 
      forward-backward translation procedure, a validation study including 100 patients 
      was carried out from June 2019 to June 2020. The following psychometric 
      properties were measured: feasibility, reliability, internal consistency, 
      validity, minimal clinically important difference (MCID), ceiling, and floor 
      effect. RESULTS: No problems were encountered during the process of translation 
      and cross-cultural adaptation of the score. The mJOA-AR was found to be a 
      feasible score. It showed high inter-observer reliability (r = 0.833, P < 0.001), 
      test-retest reliability (r = 0.987, P < 0.001) and good internal consistency 
      using Cronbach's alpha (0.777) and Pearson interclass correlation coefficient (r 
      = 0.717). The score showed good convergent and divergent construct validity 
      correlating it to the Arabic validated version of the neck disability index 
      (NDI). The mJOA-AR had an MCID of 1.506. Both the ceiling and floor effects of 
      the total score and the first and second domains were within the acceptable 
      range, while the third and fourth domains had a high ceiling effect (30% and 39%, 
      respectively). DISCUSSION: Our translated version of the mJOA score was found to 
      be a feasible score with acceptable psychometric properties. This score can be 
      utilized as a good outcome measure tool in Arabic-speaking countries.
