The possibility of using inertial motion capture systems to solve problems of labor physiology

Introduction. Improving the ergonomics of the workplace, preventing the development of fatigue and diseases of the musculoskeletal system are relevant for workers in all spheres of the modern economy. The physiology of labor is engaged in solving these issues, one of the tasks of which is to conduct an ergonomic analysis, which includes determining the severity of the labor process and determining the rationality of working postures. The search for and approbation of modern methods of increasing the objectivity and reliability of research carried out in production is an urgent direction in labor physiology. The aim of the study is comparison of the results of a hygienic assessment of the severity of the labor process in accordance with the guideline R 2.2.2006-05, carried out using standard techniques and the use of motion capture technology based on IMU-sensors, carried out at the workplace of a specialist in the management of high-rise equipment. Materials and methods. To measure the indicators of the severity of labor in accordance with the guideline R 2.2.2006-05, standard measuring instruments measuring instruments were used. The Xsens system (Netherlands) with wireless IMU-sensors "Awinda" was used as a motion capture system. Results. During this study, the possibility of using inertial motion capture systems was established as a reliable and additional tool for solving problems of labor physiology. Conclusion. It was revealed that this technology allows to increase the objectivity and reliability of ergonomic analysis and to measure quantitative indicators of the severity of labor in any production environment. At the same time, today a significant drawback is the lack of programs for processing the data obtained and the need to use standard measuring instruments.
