Introdução - A dor lombar crónica determina um elevado nível de incapacidade sendo atualmente um problema
de Saúde Pública que afeta uma grande percentagem da população ativa na Europa. A fadiga, embora subjetiva e complexa, parece ser um dos principais sintomas dos doentes com dor lombar crónica. A prevalência e a patogenia da fadiga não estão completamente esclarecidas, porém sabe-se que a fadiga interfere de forma decisiva na percepção de bem-estar e na qualidade de vida. Este estudo pretende avaliar a prevalência da fadiga em doentes com dor lombar crónica não específica e o seu impacto na funcionalidade.
Material e Métodos - Estudo clínico, transversal não-randomizado, em 30 adultos portugueses com dor lombar
crónica que incluiu a aplicação dos seguintes instrumentos: questionário de caracterização individual, escala visual analógica para dor, escala de impacto da adiga e questionário de Roland e Morris. Resultados - Verificou-se uma duração longa da dor (média de 10,6 anos) e valor moderado a alto de incapacidade na população estudada. Constatou-se uma relação estatisticamente significativa entre intensidade da dor e fadiga (p ≤ 0,05) e entre fadiga e incapacidade (p ≤ 0,001). Discussão - A fadiga é um sintoma prevalente nos doentes com dor lombar crónica e está associada à intensidade da dor e à incapacidade. Este facto realça a necessidade de uma abordagem clínica do elemento nociceptivo, entendido como gerador de limitação à atividade e à participação. Sublinha também a necessidade de um programa de reabilitação funcional que identifique e aborde de forma objectiva as variáveis dor, fadiga e função.
ABSTRACT - Introduction: Chronic low back pain causes a high level of disability and is a public health problem that currently affects a large percentage of the working population in Europe. Fatigue, although subjective and complex, seems to be one of the main symptoms of patients with chronic low back pain. The prevalence and pathogenesis of fatigue are not completely understood, but it is well known that fatigue interferes decisively in the perception of wellness and quality of life. This study aims to assess the prevalence of fatigue in patients with nonspecific chronic low back pain and its impact on functionality. Material and Methods: This was a transversal, non-randomized clinical study, with 30 Portuguese adults suffering from chronic low back pain, and included the following instruments: an individual characterization questionnaire, visual analogue scale for pain, fatigue impact scale and Roland Morris questionnaire. Results: The study showed a long duration of pain (mean 10.6 years) and moderate to high value of disability in this population. We found a significant relationship between pain intensity and fatigue (p ≤ 0.05) and between fatigue and disability (p ≤ 0.001). Discussion: Fatigue is a prevalent symptom in patients with chronic low back pain and increases with the intensity of pain. In these patients more fatigue means greater functional disability. This underlines the need for comprehensive clinical management of the nociceptive environment, understood as a potential generator of limitation on activity and participation. It emphasizes also the need for a functional rehabilitation program to identify the variables of pain, fatigue and function objectively.
