“…Furthermore, the three techniques were developed for different purposes, and were meant to capture different type of risks. However, RULA might be thought to show more precision in assessing posturerelated loads, based on the aforementioned findings and the following: (a) as stated earlier, OWAS and REBA showed a tendency to underestimate postural loads even in the iron and steel, and health care industries, respectively, which were generally known to be suitable for their application; (b) Miedema et al [38] Overall, OWAS and REBA were less sensitive to postural stress than RULA, and OWAS and REBA underestimated postural load for the considered postures, compared to RULA. This underestimation was also found in KOSHA's research [40].…”

“…Os setores de tapeçaria e montagem englobam um maior número de funcionários e, portanto, boa parte (52,1%) dos sujeitos desta pesquisa, o que pode justificar os dados obtidos, pois tais atividades requerem do funcionário a manutenção de posições fixas por períodos prolongados. Esse tipo de atividade favorece a instalação de fadiga muscular, sendo que uma exigência prolongada e excessiva acaba conduzindo também ao surgimento de lesões [19][20][21] .…”

RESUMO: Os distúrbios osteomusculares relacionados ao trabalho são afecções que atingem os tecidos moles. Têm um nexo causal com fatores de risco ergonômicos e um caráter insidioso e multifatorial, apresentando como sintoma comum dores musculoesqueléticas. O objetivo deste estudo foi investigar possível associação entre características pessoais, organização do trabalho e presença de dor em funcionários de uma indústria moveleira no município de Araçatuba, SP. Foi aplicado um questionário a uma amostra de 158 funcionários de diversos setores da empresa, com questões de caráter sociodemográfico (sexo, idade), trabalhista (setor, tempo de serviço, função desempenhada e jornada de trabalho semanal), bem como sobre sintomas dolorosos musculoesqueléticos. Dor foi relatada por 58,9% dos funcionários e relacionada de maneira significativa com o sexo (p=0,0001), setor de trabalho (p=0,0021), função desempenhada (p=0,0135) e jornada de trabalho semanal (p=0,0123). A dor predominou em mulheres, dependendo do setor, da função desempenhada e da jornada de trabalho semanal. Para tentar saná-la, a maioria dos trabalhadores usa medicamentos ou adota a atitude de ignorá-la. Os resultados sugerem a necessidade de intervenção fisioterapêutica preventiva. DESCRITORES: Dor; Saúde do trabalhador; Transtornos traumáticos cumulativos ABSTRACT: Work-related musculoskeletal disorders are diseases that affect the soft tissues. Of an insidious and multifactor nature, they often result from ergonomic risks, and show pains as a common symptom. This study searched for possible associations between personal features, labour organization and pain incidence among employees at a furniture manufacturer in the city of Araçatuba, SP. A questionnaire was administered to a sample of 158 employees from the company's different sectors in 2007, with questions addressing age and sex, labour issues (sector, seniority, position, and weekly working hours), as well as musculoskeletal pain symptoms. Pain was reported by 58.9% of the employees and significantly related to gender (p=0.0001), sector (p=0.0021), position (p=0.0135), and weekly working hours (p=0.0123). Pain was predominant in women, depending on sector, position, and weekly working hours. In order to relieve pain, most workers took medicine or simply ignored it. Results point to the need to physical therapy treatment and preventive action.

“…Meanwhile, a study found that forward head posture as well as shoulder flexion contributes to stressful high muscle activities in the upper trapezius and lower trapezius [14]. Working in a posture with hand positions above 100% of shoulder's height causes a person to feel discomfort in the shoulder and arm [15]. The potential of getting injuries increases when the workers are required to perform manual material handling in an unstable position such as working in an uneven walking surface.…”

“…Besides, posture is also related to the length of time held where a posture can be maintained for a limited period of time. The maximum holding time is the maximum period of a posture can last with or without external force exerted can be maintained continuously until maximum discomfort is experienced from a rested state [15]. Injuries may increase if the workers are exposed to the strength exertion force and exceeded endurance time [16].…”

In the industrial workplaces, manual materials handling is a necessity for the workers. However, improper materials handling technique can contribute to occupational injuries. The objective of this paper is to provide information on ergonomics risk factors and health effects associated with manual materials handling. Ergonomics risk factors include awkward posture, excessive load, and extreme temperature has been identified as main contributors to poor occupational health in manual materials handling activities.
