Ergonomic Task Analysis for Prioritization of Work-Related Musculoskeletal Disorders among Mango-Harvesting Farmers

This paper proposes a mixed ergonomic tool analysis algorithm to prioritize work-related musculoskeletal problems. study is cross-sectional assessing the prevalence of disorders (WMSDs) with associated risk factors among 14 male mango-harvesting farmers (all right-handed) mean age 52.28 ± 7.75 years. Four tasks following processes were analyzed: (1) mango harvesting, (2) transporting, (3) size sorting, and (4) weighing transporting truck. The perceived physical exertion while working on farm was based Borg CR-10 modified Standardized Nordic Questionnaire. Physical level due awkward posture evaluated by Rapid Upper Limb Assessment (RULA), whole-body in association WMSDs Entire Body (REBA) score sheets. subjective feelings fatigue normalized combined using theorem power superposition establish effective index (FEI) for determining priorities solve ergonomics-based task indicated clearly that are highly prevalent farmers, whereas highest reported right shoulder, upper arm lower back. result provided FEI ranked as follows: size-sorting task, weight-lifting harvesting task. authors concluded sorting should be first improved resolve muscle problems farmers.
