Prevalencia de trastornos musculoesqueléticos por posturas forzadas en clasificadoras de pescado de una empresa pesquera

Abstract

Objectives: To determine the prevalence of musculoskeletal disorders, and forced postures, in fish processors, in a fishing company. Materials and methods: A descriptive and transversal study was performed on a population of 20 women fish processors, of a fishing company in June 2021. The considered variables of study were: age, labor experience, musculoskeletal symptomatology and ergonomic risk due to forced postures. The Nordic Musculoskeletal Questionnaire (Kuorinka et al, 1987) was used for the detection and analysis of musculoskeletal symptoms, and for the evaluation of postural risk, the ergonomic method Rapid Entire Body Assessment (REBA) was used. Results: It was found that the median age of the workers was 27 years; 100% of the population recounted osteomuscular symptomatology, the neck (45%), dorsal region (55%) and shoulders (15%) being the most affected, besides that these osteomuscular annoyances are attributed 100% to the job and 50% of respondents added that work at home as another cause. The evaluated postures reached Action Level 4, which corresponds to a level of High risk, and action (including further assessment) is necessary soon. Conclusion: Being that the muscular affectations are common to many labor activities, in light of the results it is possible to associate the referred annoyances with the found forced postures. The early detection of these ergonomic risks is essential for an adequate and opportune intervention using preventative systems.
