Ergonomic analysis of the traditional babassu coconut opening in the city of Itapecuru-Mirim, Maranhão, Brazil

Abstract

Objective:

to understand the work situation of babassu coconut openers through Ergonomic Work Analysis (EWA) parameters.

Methods:

descriptive observational study involving female babassu coconut openers in the city of Itapecuru-Mirim/MA, Brazil, from September to November 2014, using field observations, records of images (photos and videos), questionnaires and key informants interviews. OWAS and RULA instruments were used in the EWA.

Results:

biomechanical risks were evidenced in the coconuts collecting, transporting and opening. Musculoskeletal symptoms were reported by 93.5% of the 275 participants. Backache (58.4%), lower back pain (57%), right shoulder pain (31.5%) and lower limb pain (30.1%) were the mostly reported injuries. The openers believe that such symptoms are related to their work, but the autonomy to decide on their own work routine and the good integration with their peers were identified as elements that can mitigate the effects of work load, stimulate personal satisfaction and contribute to the continuity of this secular activity.

Conclusion:

the evaluations on health and work conditions, ratified by the key informants reports, indicate the need for change in the traditional babassu coconut opening.
