Evaluación ergonómica del personal administrativo de la Facultad de Ingeniería de la UNACH mediante el Cuestionario Nórdico y el método ROSA

Computer-based administrative work requires identifying workstation ergonomic conditions and workers’ musculoskeletal symptoms. This study aimed to describe these conditions at the Faculty of Engineering of the Universidad Nacional de Chimborazo and explore the association between work experience and ROSA scores. A quantitative, non-experimental, cross-sectional study covered all ten administrative workers in the defined population. The Kuorinka Nordic Questionnaire and direct observation using Rapid Office Strain Assessment (ROSA) were employed. Frequencies, percentages and Spearman’s correlation coefficient were calculated. Over the preceding twelve months, nine participants reported neck symptoms (90%), eight reported right-wrist symptoms (80%) and eight reported lower-back symptoms (80%). Eight participants reported interference with normal activities due to neck symptoms, and eight due to lower-back symptoms. Six workstations were classified as very high risk, two as high risk and two as requiring improvement. Work experience was positively associated with ROSA scores (ρ = 0.671; two-sided asymptotic p = 0.034); an exact permutation sensitivity analysis yielded p = 0.044. Eight workstations reached scores requiring action. The findings support local intervention priorities; the small group and cross-sectional design preclude causal conclusions and generalization to other populations.
