Abstract :
Objective: To assess the intra- and inter-observer reliability of
a Brazilian Portuguese translated and cross-culturally adapted
version of the mJOA questionnaire. Methods: The reliability of the
Brazilian Portuguese version of the mJOA scale was assessed
through the evaluation of a sample of patients with cervical myelop-
athy 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. Results: Fifty-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). Conclusion:
The Brazilian Portuguese translated and cross-culturally adapted
version of the mJOA questionnaire appears to be valid and reliable.
