Estudio de riesgos ergonómicos en conductores de transporte pesado y la influencia de malas posturas en la generación de molestias musculoesqueléticas: análisis biomecánico con Kinovea en conductores de transporte pesado en la generación de molestias musculoesqueléticas. 0.

Abstract

The purpose of this project is to analyze the biomechanics in heavy load transport drivers through the Kinovea software, prolonged static postures are analyzed in the generation of musculoskeletal discomfort, generating necessary information on preventive ergonomics that helps the professional driver, in addition, it will be provided Information requested about the activities, as well as the type of vehicle, routes, driving times and rest of your working day. This study begins by managing an ethics protocol between the company and the volunteer staff to carry out surveys and with the use of the ergonomic evaluation method called RULA, the most critical positions to be analyzed were determined. Once the area to be analyzed is determined, markers are placed at the anatomical points of interest, for this study in the sagittal plane of the spine and with the use of a mobile device with good resolution, initial videos were made capturing the typical postures in their space of study. worked. The videos are analyzed and the most relevant fragments are taken to process them through the use of Kinovea software which, thanks to its tools such as trajectory tracking, displacement measurements, speed and time spent, two-dimensional records of critical movements are obtained. Finally, with the use of MATLAB software, the kinematics of the subject's spine are obtained. In the global study, it is applied in the Bioengineering Laboratory through the photogrammetry of a subject that reproduces the movements in a controlled environment in order to propose an experimental pilot protocol, in addition, with the help of sensors, efforts will be measured in certain muscles. areas to establish criteria. reduce the generation of musculoskeletal discomfort.
