Prevalencia de dolor lumbar y nivel de riesgo de manipulación manual de cargas en bodegueros de una empresa de cerámica

Abstract

To estimate the prevalence of low back pain and determine the risk level of manual handling of loads among warehousemen of a ceramic tile company located in the city of Quito in 2020. Method: A transversal descriptive cross-sectional was carried out in a population of 30 warehousemen. The Nordic questionnaire (Kuorinka, 1987) was used to determine the frequency of the symptoms per body segment, and the risk factor of manual handling of loads was evaluated by using the NIOSH lifting equation for multiple tasks. Results: It was found that 66.67% of the population reported low back pain in the last year. At total of 26% of cases was examined by a specialist, and they believe the pain is caused by work. Based on the composite lifting index, the risk level of manual handling of loads is high. Conclusion: Overtime, low back pain might lead to an occupational disease due to the high level of manual handling of loads. It is recommended to take preventive measures to improve the conditions in the workplace.
