Diseño e implementación de un sistema para el análisis ergonómico de la postura del tronco al estar sentado mediante el uso de dispositivos de unidad de medida inercial

Abstract

The inadequate corporal postures cause the body to be more susceptible to developed medical problems such as slight pain and fatigue, or more serious ones like musculoskeletal harms and deformations in the vertebral column. To bring a comfortable and reliable solution in the prevention of occupational diseases, a system was design and implement, which uses a mobile application to notify the users about the incorrect postures that they adopt. In order to do it, the posture of the torso while sitting is identified, by processing the data of the IMU devices located in the cervical zone and in the mayor trochanter by the prototypes developed. The postures are classified as acceptable or inadequate base on the ISO Norm 11226:2000 and in the ergonomic study of the torso in the sitting posture.
