Resumo(s)
Este trabalho teve por objetivo a realização de uma análise ergonómica ao trabalho realizado nos Viveiros de uma Câmara Municipal com particular ênfase na avaliação do risco de desenvolvimento das LMERT. Para avaliação do risco de LMERT recorreu-se a dois métodos: REBA (Rapid Entire Body Assessment) e QEC (Quick Exposure Check). A existência de associação entre as variáveis (sociodemográficas e do trabalho) e a presença de dor (por região corporal) foi testada com recurso ao teste exato de independência do Qui-quadrado. Para comparar os resultados obtidos por método e por tarefa recorreu-se aos testes não paramétricos de Wilcoxon e Kruskal-Wallis, respetivamente. Onze tarefas foram analisadas e avaliadas com ambos métodos. Considerando a auto-referenciação de queixas, foram destacadas cinco regiões coporais. Tendo em conta os resultados REBA e QEC, o risco para o desenvolvimento de LME está presente em todas as tarefas (Nível de risco ≥2). Em geral não se encontraram diferenças estatisticamente significativas entre os resultados alcançados por ambos os métodos contudo, uma sobrestimação foi obtida em 45% e 25% dos casos avaliados com o REBA e QEC, respetivamente.
An Ergonomic Work Analysis was accomplished at plant nurseries of a Portuguese Municipality aiming at assessing the actual working conditions and the complaints presented by the workers; characterizing each task in terms of the associated MSD development risk and proposing preventive measures. MSD developing risk assessment relied on two methods: Rapid Entire Body Assessment (REBA) and Quick Exposure Check (QEC). The Chi-square test was used to assess associations between variables (demographic/work-related characteristics) and reported MSD symptoms. To compare REBA and QEC results the non-parametric Wilcoxon test was used whereas to compare the tasks risk level the non-parametric Kruskal-Wallis test was used. Eleven tasks were analyzed and assessed with the both methods. Considering the self-reported complaints, five body region, with the highest percentage of complaints, were highlighted. Globally, considering the REBA and QEC results, the risk for the development of MSDs is present in all tasks (Risk Level ≥ 2). Despite these results, in general there were no statistically significant differences between the results obtain by both methods. Overestimation was obtained in 45% and 25% of the cases assessed with REBA and QEC, respectively.
