Background and Objective: Cervical spondylotic myelopathy (CSM) is a common cause of significant clinical morbidity. The modified Japanese Orthopedic Association score (mJOA) is a very short instrument for functional evaluation in these patients. This study aimed to evaluate functionality in patients diagnosed with CSM diseases using the mJOA and to compare the scores based on age, sex, and type of disease.
Methods: A sample of patients with CSM who were candidate for decompressive surgery entered into this cross sectional study. The mJOA scores were obtained for the functional assessment of patients. Score on the mJOA range from 0 to 18 with higher scores indicating a better condition. In addition to descriptive statistics, the data were compared among study subgroups as categorized by age, gender and type of disease.
Results: A total of 63 patients were studied. The mean age of the patients was 54 ± 8.3 (SD)(range 21-79 years) All patients diagnosed as having cervical herniated disc (n = 36) or cervical spinal stenosis (n = 27). Overall, the mean mJOA score for all patients was 9.82 (SD = 1.0). The mJOA score for men were significantly higher than women (P < 0.0001). The mJOA score in younger patients was significantly higher than older patients (P < 0.0001). No significant difference was observed for type of disease (P = 0.47).
Conclusions: The findings of the study suggest that functionality score as measured by the mJOA can be a useful parameter for clinicians help them to manage patients with cervical spondylotic myelopathy prior to surgery.
