Análisis de riesgos ergonómicos en las estaciones de trabajo de los docentes de la Escuela Politécnica Nacional mediante el método Rapid Office Strain Assessment (ROSA)

Abstract

The teachers at the Escuela Politécnica Nacional engage in academic and administrative activities, which require them to remain seated in a chair and work at a desk manipulating a Data Visualization Display (DVD). The Rapid Office Strain Assessment (ROSA) method was applied to 86 workstations, comprising 59 men and 27 women, with the aim of analyzing the level of ergonomic risk to which they are exposed. It was determined

that female teachers have a higher ergonomic risk, with 85% classified as having a high or very high-risk level, while male teachers have a high or very high-risk level of 60%. In addition, surveys were conducted among the teachers to determine which body areas are most affected. The results showed that the lower back region has the highest incidence, with 49% of men and 52% of women reporting issues. The neck region follows with 41% for men and 52% for women, and the shoulder region with 27% for men and 41% for women. The wrists are affected in 19% of men and 22% of women, while the elbow region does not show significant impact on any teacher.
