[French validation of a disability rating scale for the evaluation of low back pain (EIFEL questionnaire)]

Functional disability is one of the main components of low back pain (LBP)-associated morbidity and should be taken into account in the evaluation and care of patients. This article describes the French-language adaptation and validation of the Roland and Morris Disability Questionnaire. This self-administered questionnaire proved rapid, simple to use, reliable, valid, and sensitive to changes in clinical status, suggesting that its widespread use may be possible in settings ranging from epidemiological or clinical research to individual LBP patient evaluation in daily clinical practice.
