Comparação entre ROSA, REBA, RULA e OWAS na avaliação postural de funcionários de uma Universidade Federal

Abstract

Postural disorders at work are considered a personal problem, subject to changes by each individual to reduce or eliminate the risk. Methods have been developed to determine and quantify postural risks, although the risk classification may differ depending on the method used in the analysis. The objective of this course completion work (TCC) was to carry out a comparative analysis between the ergonomic assessment methods RULA, REBA, OWAS and ROSA of employees at the Federal University of Alagoas (UFAL), looking for similarities and obvious differences in their use. . Methodologically, postural risk was classified using the Rapid Office Strain Assessment (ROSA), Rapid Whole Body Assessment (REBA), Rapid Upper Limb Assessment (RULA) and Ovako Working Posture Analyzing System (OWAS) protocols. During the application of the methods, the time spent in position, posture and application of force during scientific activities during observations was analyzed. The work included three activities present at the university, they were: the librarian, the materials laboratory teacher and the cleaning staff. Thus, according to the results obtained through the application of correlations between the possible methods to achieve the proposed objective, it was noted that there is a strong observation with a score of 1, the RULA and REBA methods, these two methods present a high similarity in terms of their application, the demonstration between the OWAS and RULA and OWAS and REBA methods presents a demonstration with a rating of 0.866 and the ROSA method presents an inverse demonstration with the other methods, due to the fact that this method is completely opposite in the form of postural analyzes to the others.
