Resumo
Introdução: a dor lombar se mantém como uma das condições com os maiores índices de afastamento do trabalho, além de fatores biopsicossociais, como fatores psicológicos podem agravar essa condição, a catastrofização e uma hiperativação, que pode gerar espasmo muscular e dor. A fadiga muscular sobrecarrega elementos passivos, causando diminuição da função. Objetivo: Comparar o desempenho nos testes de fadiga entre indivíduos com e sem Dor Lombar Crônica após o protocolo de sobrecarga lombar nos aspectos de força, resistência e dor. Métodos: A amostra foi composta de 30 indivíduos adultos com idade entre 18 a 30 anos, de ambos os sexos, foram formados dois grupos: Grupo Dor Lombar Crônica (n=15) e Grupo Controle (n=15). Foram utilizados os seguintes instrumentos na avaliação: anamnese, para obtenção de dados pessoais e história clínica. Em seguida foi aplicada a Escala Visual Analógica, dinamometria de extensão lombar, teste de resistência dos músculos extensores de tronco (Biering-Sorensen) e após a aplicação dos testes foi feito o protocolo de sobrecarga lombar. Em seguida, as mesmas avaliações foram realizadas. Resultados: Após o protocolo de sobrecarga lombar, houve aumento do nível de dor e do desempenho na dinamometria dorsal, e redução do desempenho no teste de Biering-Sorensen. Conclusão: Os dados do presente estudo, nas condições metodológicas utilizadas, permitem concluir que indivíduos com dor lombar apresentam aumento da dor e pior desempenho na resistência dos músculos extensores do tronco após serem submetidos à sobrecarga lombar.
Introduction: Low back pain (LD) remains one of the conditions with the highest rates of absence from work, in addition to biopsychosocial factors, such as psychological factors can aggravate this condition, catastrophizing and hyperactivation, which can generate muscle spasms and pain. Muscle fatigue overloads passive elements, causing decreased function. Objective: To compare the performance in fatigue tests between individuals with and without Chronic Low Back Pain (LCD) after the lumbar overload protocol in terms of strength, endurance, and pain. Methods: The sample consisted of 30 adults aged between 18 and 30 years, of both sexes, who were formed into two groups: Chronic Low Back Pain Group (GDL, n=15) and Control Group (CG, n=15). The following instruments were used in the evaluation: anamnesis, to obtain personal data and clinical history. Then, the Visual Analogue Scale (VAS), dynamometry of lumbar extension, and resistance test of the trunk extensor muscles (Biering-Sorensen) were applied and after the application of the tests, the lumbar overload protocol was performed. Then, the same evaluations were performed. Results: After the lumbar overload protocol, there was an increase in the level of pain and the performance in the dorsal dynamometry and a reduction in the performance in the Biering-Sorensen test. Conclusion: The present study’s data, under the methodological conditions used, allow us to conclude that individuals with low back pain present increased pain and worse performance in the resistance of the trunk extensor muscles after being submitted to lumbar overload.
