Evaluación comparativa de los riesgos ergonómicos mediante las metodologías REBA y RULA en los puestos de trabajo de la empresa GELCO.

Abstract

Abstract: Ergonomic risks associated with awkward postures, repetitive movements, and heavy load handling are among the leading causes of musculoskeletal disorders in the workplace. This study aimed to conduct a comparative assessment of ergonomic risks at the company GELCO using the Rapid Entire Body Assessment (REBA) and Rapid Upper Limb Assessment (RULA) methodologies; this analysis was supplemented by the use of ERGO IBV software to achieve a more comprehensive evaluation of ergonomic conditions. The research employed a quantitative approach using descriptive statistics to analyze work postures at GELCO and utilized an observational, cross-sectional, and comparative design to contrast the methodologies applied. The results revealed higher postural loads on the neck, trunk, and forearm. REBA provided a superior comprehensive assessment of body posture, while RULA demonstrated greater sensitivity in identifying risks to the upper limbs; ERGO IBV offered a complementary evaluation that identified factors related to repetitiveness, exposure, and the conditions of the task being performed.
