Aplicações do método OWAS: uma análise bibliométrica

Abstract

The Ovako Working Posture Analysis System (OWAS), developed in Finland in the 1970s by Karhu, Kansi, and Kuorinka, is an ergonomic tool designed to analyze working postures in industrial environments, initially in the steel production sector. OWAS categorizes work postures into specific classes to identify risks of musculoskeletal disorders, facilitating the implementation of corrective measures. The methodology employs a coding system to identify harmful postures, allowing interventions to improve working conditions. However, OWAS has limitations, primarily due to its simplified approach, which does not consider details of body segments such as the neck, wrists, and forearms. This limitation can lead to an underestimation of risks and a lack of consideration for dynamic and varied postures, compromising the accuracy of ergonomic assessment. For a more comprehensive analysis, combining OWAS with other methodologies, such as the Rapid Upper Limb Assessment (RULA), which focuses on upper limb postures and movements, is recommended. This study conducted a bibliometric analysis of OWAS using the Scopus database and Biblioshiny. The objective was to map the trajectory, trends, and evolution of the method, identifying key authors, journals, and countries involved in OWAS research and application. Additionally, the study aimed to identify research gaps, evaluate the impact and influence of studies using OWAS, and understand its diffusionand influence in ergonomic practice.
