ObjectiveTo assess the intra- and inter-observer reliability of a Brazilian Portuguese translated and cross-culturally adapted version of the mJOA questionnaire.MethodsThe reliability of the Brazilian Portuguese version of the mJOA scale was assessed through the evaluation of a sample of patients with cervical myelopathy by two independent experienced spine surgeon examiners. Inter-observer reliability was defined by the Intraclass Correlation Coefficient (ICC) between the evaluations of the two examiners, and intra-observer reliability was assessed by the ICC between the two evaluations of one examiner.ResultsFifty-five patients were included in the study (mean age 58.7 years). The ICC for inter-observer reliability of the Brazilian Portuguese version of the mJOA was 0.967, and the ICC for intra-observer reliability was 0.869, both classified as “almost perfect” (> 0.81).ConclusionThe Brazilian Portuguese translated and cross-culturally adapted version of the mJOA questionnaire appears to be valid and reliable.

Introduction The modified Japanese Orthopaedic Association (mJOA) score is considered to be among the most comprehensive scores in the assessment of patients with cervical myelopathy. Hence, providing reliable, translated, and cross-culturally adapted versions in different languages is required to standardize the evaluation of patients. This study aimed to translate a reliable Arabic version of the mJOA score. Methods A total of 65 patients of variable age and with etiologies for compressive cervical myelopathy were recruited. Both forward and backward translations were performed. Then, intraobserver and interobserver reliabilities were measured using the intraclass correlation coefficient and Cronbach's alpha coefficient. Results The mean age of the patients was 58.08 years, and most of them were male (69.2%). The intraobserver and interobserver reliabilities were almost in perfect agreement for the different sections and the total score, which were 96.8% and 97.4%, respectively. Conclusions In this study, a reliable, cross-culturally adapted Arabic version of the mJOA score for patients with cervical myelopathy is provided. Although the study was conducted on Egyptian patients, we believe that it could be implemented in majority of the Arabic-speaking population.

Pratali RR. Study of the reliability of a dynamic magnetic resonance imaging technique for cervical spondylotic myelopathy [Thesis]. Ribeirão Preto: University of São Paulo, Faculty of Medicine of Ribeirão Preto; 2019.Since dynamic factors may contribute to the etiology and severity of cervical spondylotic myelopathy (CSM), dynamic (flexion-extension) magnetic resonance imaging (MRI) may be useful to better evaluate for spinal stenosis and cord compromise. The objectives of the present study were to evaluate morphometric variations of the cervical spine in patients with CSM using a standard technique of dynamic MRI, to assess the inter-and intra-observer reliability of measurements of morphometric parameters based on this imaging, and to compare the resulting measurements with those previously published. Dynamic cervical MRI was obtained using a standard protocol with the neck in neutral, flexion, and extension positions. The morphometric parameters considered were anterior length of the spinal cord (ALSC), posterior length of the spinal cord (PLSC), spinal canal diameter (SCD) and spinal cord width (SCW). Two observers analyzed the parameters independently, and the inter-and intra-observer reliabilities were assessed by the intraclass correlation coefficient (ICC). 18 patients were included in the study and all completed the dynamic MRI acquisition protocol. The inter-and intra-observer reliabilities demonstrated "almost perfect agreement" (ICC > 0.9; p < 0.001) for ALSC and PLSC in all positions. The SCD had inter-and intra-observer reliability classified as "almost perfect agreement" (ICC: 0.83-0.98; p < 0.001 and ICC: 0.90-0.99; p < 0.001, respectively) in all positions. The SCW had inter-and intra-observer reliability classified as "substantial agreement" (ICC: 0.73-0.94; p < 0.001 and ICC: 0.79-0.96; p < 0.001, respectively) in all positions. ALSC and PLSC in neutral, flexion and extension positions from the present study were significantly different compared to the measurements previously published (p < 0.001).As conclusion, the dynamic MRI protocol presented was safe and may allow a more complete evaluation of variations in the cervical spine in patients with CSM than traditional MRI protocols. The morphometric parameters based on this protocol demonstrated excellent interand intra-observer reliabilities.
