Summary: | Background: Low back pain is a considerable global public health problem. Use of back belts in occupational settings arises from the expectation of countless biomechanical benefits, which together would contribute to the prevention of this problem. Objective: To orient students, physicians and health institutions on the use of back belts, lumbar support or braces for prevention of low back pain or injury among asymptomatic workers. Method: The present guideline was developed based on a systematic literature review; 809 studies were located in database MEDLINE and 571 in EMBASE and Cochrane CENTRAL. Evaluating back-belt use as preventive intervention against low back pain demands quantifying benefits, harms and difficulties to implementation, as well as the methodological quality of primary studies. Conclusion: Despite the weak benefits reflected in the individual, partial and isolated results of a few studies, there is no consistent evidence for the use of back belts, lumbar supports or braces for primary prevention of low back pain or occupational low back injury among workers. According to the available evidence, back-belt use is not associated with reduction of absenteeism. Keywords | orthotic devices; primary prevention; low back pain. Introducao: Lombalgia e um problema internacional importante de saude publica. O uso de cinta lombar no meio ocupacional emerge da expectativa de inumeros beneficios biomecanicos que, em conjunto, promoveriam a prevencao desse problema. Objetivo: Orientar estudantes, medicos e estabelecimentos de saude sobre o uso de cinta lombar, suporte ou ortese lombar como prevencao da lombalgia ou de lesoes lombares em trabalhadores sem sintomatologia atual. Metodo: Ela foi desenvolvida a partir da revisao sistematica da literatura: da base de dados MEDLINE, foram recuperados 809 trabalhos e das bases EMBASE e Central Cochrane, 571. Avaliar a cinta lombar como intervencao preventiva de lombalgia envolve a quantificacao de beneficios, maleficios e facilidade de sua implementacao, assim como a qualidade metodologica dos estudos primarios. Conclusao: Apesar do beneficio demonstrado fracamente em resultados individuais, parciais e isolados em poucos estudos, nao ha evidencia consistente que sustente a utilizacao de cinta lombar, suporte ou ortese lombar na prevencao primaria da lombalgia ou de lesoes lombares ocupacionais em trabalhadores. As evidencias, agrupadas, apontam para ausencia de reducao de absenteismo com o uso da cinta lombar. Palavras-chave | aparelhos ortopedicos; prevencao primaria; dor lombar. |
