Posturas forzadas en los trabajadores del puesto de encuellador en el taladro de perforación hidrocarburífero.

Abstract

Objectives: Evaluate the levels of ergonomic ricks due to forcerd postures with the REBA method in the workers of the striker position, to reduce the incidence and prevalence of pain in the dorsalumbar región, identify which task has the greatest biomechanical load (asymmetric) of the striker position and expose the musculoskeletal symptomatological perception by age, body segment and time in the last 12 months. Materials and methods: Descriptive cross- sectional study with 25 workers from the hydrocarbon drilling rig of and oíl Company, in the province of Sucumbíos. The Kuorinka Nordic Questionnaire was used to determine musculoskeletal symptoms by crossing data with the SPSS Software Version 24.0 and the ergonomic REBA method for the risk levels for Forced postures analyzed by means of the Ergo/IBV software. Results: Very high levels of ergonomic risks due to forcerd postures were demonstrated, and tasks 1 and 2 present a high postural asymmetric biomechanical load at 100.00%. On the other hand, the Nordic Questionnaire determined the relative frequency of symptoms in the thoracolumbar segment of the 3 age groups, although in the last 12 months it has been maintained in the 30 – 39 years- old personnel in the dorsolumbar área with 50.00%. Conclusion: A relationship is established between the results obtained from the asymmetric ranges(REBA) in neck, dorsolumbar and wrist segments (100.00%) and by symptomatology(Nordic) in the neck (88.88%), in the dorsolumbar (100.00%) in the group of 20 to 29 years and wrist (75.00%) of the group of 40 to 45 years.
