Ergonomic risks and their relationship with musculoskeletal disorders. Study in municipal employees.

Abstract

The study presented had the objective of identifying, measuring and evaluating ergonomic risks and suggesting preventive measures to mitigate them, due to the specificity of the experimental unit, there are a total of 16 officials from the Planning Department of the Municipal GAD of Guano Canton, The study population consisted of a non-probabilistic sample. The instruments used were the OWAS, REBA and Nordic questionnaires, related to postural physical effort in the workplace, by observing 25 min of specific non-cyclical tasks, their musculature was assessed globally. In the second method, the upper and lower extremities are grouped by analyzing the postural stress assumed during work. This method determines the action level to plan timely corrections. The applied Nordic questionnaire determines and analyzes the musculoskeletal symptoms and allows considering the degree of ergonomic risk. The results showed that the ergonomic risks for the administrative staff were not related to physical effort (p=0.604), but to factors of forced, repetitive and prolonged postures during working hours (p=0.05; p=0.029). Ergonomic risk is an important factor influencing the development of musculoskeletal disorders (MSD) symptoms, suggesting improvements in the work environment, which constitutes physical and mental health and personal development.
