Implementing Participatory Ergonomics Among Indigenous Women of Ecuador to Preserve Ancestral Customs and Knowledge

Abstract:

Severe spine deformations are common among elderly indigenous women of Ecuadorian highlands mainly dedicated to agricultural labors. Participatory Ergonomics (PE) is used to reduce or eliminate the incidence of musculoskeletal disorders. Two demanding daily activities of these women were evaluated with MREBA and 3DSSPP, then the ergonomic recommendations were discussed with the ERGO group, and their opinions regarding the proposals were used to modify them according to the women traditions and customs. The PE is an effective instrument to adjust the recommendations, in the case of this study to be respectful of the customs and traditions of the intervened community. However, the ingrained customs suggest that the modifications should be implemented gradually, especially for older women who have the most compromised musculoskeletal health. A major detected problem is the great magnitude of the loads these women lift and transport, tied to their backs (sacks or children) since they exceeded by far the recommended levels.
