Evaluación de trastornos musculoesqueléticos por postura forzada en personal masculino que labora en cámaras frías de empaque en una florícola

Abstract

Objectives: Identify the perception of musculoskeletal symptoms in postharvest personnel, evaluate the level of ergonomic risk due to forced postures of the jobs in the packing area and determine which position exhibits the greatest postural overload. Materials and methods: Descriptive cross-sectional study carried out on 30 male workers from the cold store postharvest area in Cayambe - Ecuador. The Nordic Standardized Questionnaire for the perception of musculoskeletal symptoms was used, these data analyzed with the SPSS Version 24 Statistical Software and the ergonomic REBA method to evaluate the risk levels for forced postures and asymmetry range examined with the Ergo Study Software. Results: The perception of musculoskeletal symptoms by age is identified, in personnel between 20 and 30 years old in the lower back segment and workers with less than 3 years of work experience presented shoulder and wrist discomfort. High risk levels are determined in the packing area due to forced postures and the packing station is the one with the greatest postural overload in the wrist, neck and trunk and the arm and leg segments. Conclusion: A possible correlation is established between the perception of wrist musculoskeletal symptoms in personnel who have been working for more than 5 years and the high postural overload of the mentioned segment evaluated with the REBA Method.
