Resumo: | With the rapid development of civil aviation in Brazil there was a large number of subjects involved in the aircraft maintenance work. Much of workers develop tasks involving manual material handling (MMH), which already have evidenced musculoskeletal risks. However, workers from the aircraft maintenance industry suffer huge pressure due the safety issues and the quality of the work that is performed. There were no studies in the literature that addressed the risk factors present in this sector. Thus, the aim of Study 1 was to evaluate the psychosocial indicators, as well as reports of musculoskeletal symptoms and disorders among workers iof the aircraft maintenance industry. One hundred and one employees were assessed using the Nordic Musculoskeletal Questionnaire, a standardized physical examination, the Job Content Questionnaire and the Utrecht Work Engagement Scale. The results indicate that the workers are exposed to good psychosocial conditions, which have neither prevented the emergence of musculoskeletal disorders, nor the self reported pain and functional disability, particularly associated with the lower back. As the MMH was the main activity performed by the aircraft maintenance workers assessed, musculoskeletal disorders seem to be associated with the biomechanical characteristics of this activity. Despite the risks already identified, the literature suggests some strategies for reducing the physical load imposed to the musculoskeletal system during MMH. These strategies such as the implementation of handles on boxes, ensuring better coupling object/hands during handling. However, the recommendations of adaptations in boxes are not conclusive regarding handle placement, and their impact on workers' musculoskeletal conditions. Thus, the Study 2 was conducted based on a systematic literature review. The aim was to synthesize evidence regarding the effect of adjustment on boxes, aiming at reduction of musculoskeletal load. A survey was conducted in the following databases: Embase, Pubmed / Medline, Web of Science, and Lilacs Bireme CINAHAL, Sportdiscuss, Cochrane. Two reviewers independently selected the relevant studies, and any disagreements were solved by consensus. Cross-sectional studies were included. The scale proposed by Ariens (2000) was used to assess the quality of the studies included in this review. The electronic search yielded a total of 1170 references published in English. At the end of the selection process, and after manual search of references, the selection included 15 cross-sectional studies. Due to do the great methodological variability, regarding both methods and the proposed adaptations (size and mass of boxes), associated with the low quality of the studies prevented the synthesis of evidence. There is a need of using objective and subjective methods to evaluate standardized boxes with handles, which can also be applied to the assessment of other ergonomic interventions. Furthermore, the handles should be investigated using various positions and inclinations, and the MMH has to be carried out to different heights, in order to provide more conclusive evidence to support the implementation of those adaptations in the occupational practice. Experienced subjects have also to be considered in future studies. |

Grande parte dos trabalhadores desenvolvem tarefas que envolvem a realização do manuseio de cargas, o qual já tem grandes evidências de riscos musculoesqueléticos. No entanto, o setor de manutenção de aeronaves sofre grandes pressões com a segurança e com a qualidade do trabalho realizado. Não foram encontrados na literatura estudos que abordassem os fatores de risco presentes neste setor. Dessa forma, o Estudo 1 teve como objetivo avaliar os indicadores psicossociais, assim como os relatos de sintomas musculoesqueléticos entre trabalhadores do setor de manutenção de aeronaves. Cento e um funcionários foram avaliados por meio do Questionário Nórdico de Sintomas Osteomusculares, por uma avaliação física padronizada e pelas Escala de Estresse e Trabalho e a Escala de Bem Estar e Trabalho. Os resultados indicam que trabalhadores da indústria de manutenção de aeronaves envolvidos com tarefas de manuseio de materiais são expostos a boas condições psicossociais, o que não impediu o surgimento de distúrbios musculoesqueléticos, nem o alto índice de relato de dor e incapacidade funcional, particularmente associado com a parte inferior da coluna. Como o manuseio de materiais foi a principal atividade realizada no setor de manutenção de aeronaves avaliado, os distúrbios musculoesqueléticos encontrados foram associados às características biomecânicas desta atividade. Apesar dos riscos já identificados, a literatura aponta algumas estratégias para redução da carga física imposta ao sistema musculoesquelético durante o manuseio de cargas. Tratam-se de estratégias nos instrumentos de trabalho, como a implementação de pegas em caixas, garantindo melhor acoplamento objeto/mãos durante o manuseio. No entanto, as adaptações em caixas não são conclusivas em relação às recomendações de posicionamento e sua repercussão nas condições musculoesqueléticas dos trabalhadores. Desta forma, foi realizado o Estudo 2 desta dissertação a partir de uma revisão sistemática da literatura. O objetivo foi sintetizar evidências em relação ao efeito da adaptação de caixas na redução da carga musculoesquelética. Foi realizada pesquisa nas seguintes bases de dados: dados Embase, Pubmed/Medline, Web of Science, Bireme e Lilacs CINAHAL, Sportdiscuss, Cochrane. Dois revisores independentes selecionaram os estudos pertinentes, e as eventuais discordâncias foram solucionadas por consenso. Foram incluídos estudos tranversais. A escala proposta por Ariens (2000) foi utilizada para avaliação da qualidade dos estudos incluídos nesta revisão. A busca eletrônica resultou em um total de 1170 referências publicadas em inglês. Ao final do processo de seleção e da busca manual das referências dos artigos inicialmente incluídos na revisão, totalizou-se a seleção de 15 estudos transversais. A grande variabilidade metodológica, tanto em termos de avaliação como em relação às formas de adaptação de pegas propostas, tamanho e massa das caixas, associadas à baixa qualidade dos estudos incluídos, inviabilizou o agrupamento dos estudos para síntese de evidência. Observa-se a necessidade da utilização conjunta de metodologias objetivas e subjetivas padronizadas na avaliação de caixas adaptadas com pegas, o que pode ser estendido para outros tipos de intervenções ergonômicas. Além disso, as caixas adaptadas precisam ser investigadas a partir de diferentes posicionamentos e inclinações das pegas, a serem manuseadas em diferentes alturas, para fornecer evidências mais definitivas para a implementação na prática ocupacional. A questão da experiência dos sujeitos avaliados também deve ser considerada em estudos futuros.Universidade Federal de Sao Carlosapplication/pdfporUniversidade Federal de São CarlosPrograma de Pós-Graduação em Fisioterapia - PPGFtUFSCarBRFisioterapiaDoenças profissionais prevençãoCarga de trabalhoManuseio de cargaErgonomiaAviaçãoDesign ergonômico de caixasPegasDistúrbios musculoesqueléticosPhysical therapyPreventionErgonomicsAviationErgonomic design of boxesManual materials handlingHandlesMusculoskeletal disordersCIENCIAS DA SAUDE::FISIOTERAPIA E TERAPIA OCUPACIONALManuseio de carga : sintomas musculoesqueléticos e indicadores psicossociais em ambiente real e efeito da adaptação de caixas na redução de fatores de riscoinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesis-1-1abcad86a-2e7f-4b8e-931b-5764becc5fafinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFSCARinstname:Universidade Federal de São Carlos (UFSCAR)instacron:UFSCARORIGINAL4746.pdfapplication/pdf1426086https://repositorio.ufscar.br/bitstream/ufscar/5303/1/4746.pdff41b8c37c91b06ab62579658c926ad62MD51TEXT4746.pdf.txt4746.pdf.txtExtracted texttext/plain0https://repositorio.ufscar.br/bitstream/ufscar/5303/2/4746.pdf.txtd41d8cd98f00b204e9800998ecf8427eMD52THUMBNAIL4746.pdf.jpg4746.pdf.jpgIM Thumbnailimage/jpeg6300https://repositorio.ufscar.br/bitstream/ufscar/5303/3/4746.pdf.jpg4152b5794b2e44324742eddcd51acb16MD53ufscar/53032023-09-18 18:31:35.848oai:repositorio.ufscar.br:ufscar/5303Repositório InstitucionalPUBhttps://repositorio.ufscar.br/oai/requestopendoar:43222023-09-18T18:31:35Repositório Institucional da UFSCAR - Universidade Federal de São Carlos (UFSCAR)false |
