Análise das propriedades de medida de questionários traduzidos e adaptados para o português brasileiro que mensuram funcionalidade em pacientes com dor lombar

Abstract

Background: Low back pain is very common in the world population, being more prevalent in people of working age, which causes functional, psychosocial and economic impacts for the person, his family and his country. Assessing functionality is extremely relevant in low back pain and is one of the most important points of physical therapy assessment. Purpose: To list all questionnaires that measure functionality, on at least one scale, in individuals with low back pain, which were translated and adapted to Brazilian Portuguese, as well as critically analyze their measurement properties by comparing them. Methods: In May 2022, a search was performed on the MEDLINE platform with the terms “Dor lombar” AND “questionário” AND “brasileiro” OR “português” in order to produce a literature review study. Results: Nine studies were found, with six questionnaires: Brazilian Roland Morris Disability Questionnaire (RMDQ), Brazilian Quebec Back Pain Disaility Scale (QBPDS), Brazilian Owestry Disability Index (ODI), Funtional Rating Index (FRI), Escala Funcional Específica do Paciente (PSFS) e Brazilian Bournemouth Questionnaire (BQ). All questionnaires were translated and adapted to Brazilian Portuguese. The most evaluated properties of measures were internal consistency, reproducibility and validity. Conclusion: A consistência interna e a validade foram melhores para o QBPDS; a confiabilidade foi maior para o ODI; PSFS foi melhor em termos de capacidade de resposta. This study presented instruments that can be used by physical therapists and other health professionals in Brazilian individuals because they present adequate validity, reliability and internal consistency to assess functionality related to low back pain. However, further studies should be carried out to verify the responsiveness of all questionnaires.
