Abstract
ABSTRACT Objective: The Back Pain Functional Scale (BPFS) was designed to evaluate the functional state of individuals with low back pain. The scale consists of twelve items, covering functional aspects of the daily life activities of these individuals. The final score is calculated by summing the responses to each item, the values of which range from 0 to 5, obtaining a total result of 0 to 60 points. Methods: The validation process was developed in accordance with the World Health Organization (WHO) protocol, covering translation, back translation, semantic equivalence, evaluation by specialists from previous stages, pre-test of the tool, and final version. Subsequently, the final version was applied in a sample of 90 individuals and the data obtained were subjected to descriptive statistical analysis, factorial analysis, evaluation of internal consistency, and correlation with other validated tools. Results: The tool was adapted to Brazilian Portuguese, making use of terms to approximate the language of everyday expressions. The final version presented results similar to those from the original version, as demonstrated by the factorial analysis, the internal consistency (Cronbach's alpha: 0.990), and the strong correlation with tools validated for the Portuguese language. Conclusion: The Brazilian version of BPFS proved to be easy to apply and understand, and presented high internal consistency and construct validity similar to that of the original instrument. Level of evidence 1B; Study of adaptation of a valid score.
Highlights
Low back pain or lumbalgia is a symptom, not a disease, and can result from various known or unknown abnormalities or diseases
The final version of the Back Pain Functional Scale (BPFS) was applied to 90 individuals of both sexes (75 females and 15 males) with a mean age of 45.8±11.8 years and mean body mass index of 29.2±5.9 kg/m2, who volunteered to participate in the study
Related to low back pain, we highlight the use in Brazil of the Quebec Low Back Disability scale and the Roland Morris Questionnaire, both validated for the Portuguese language.[22]
Summary
Low back pain or lumbalgia is a symptom, not a disease, and can result from various known or unknown abnormalities or diseases. It is defined by the location of the pain, typically between the lower margins of the ribs and the gluteal folds. The condition is often accompanied by pain in one or both lower limbs and some people have associated neurological symptoms.[1]. In Brazil the incidence of low back pain is known to be high (>50%), but the fragility of Brazilian studies may mean that the real numbers for this condition are underestimated.[5]
