Determinate muscle strain of assembly workers by applying advanced EMG measurement

Abstract

Contemporary organizations tend to improve the safety and health of workers through the relief of workers from performing strenuous and tiring activities. Musculoskeletal disorders (MSDs) that occur as a result of repeating the same movement over a long period of time, straining and bending the body or performing assembly activities in an ergonomically inadequate body position represent one of the major problems faced by organizations, which further leads to more and more absenteeism of workers from work, reduced productivity and increased costs. The main aim of the research paper is to show the results of monitoring of muscle activity during the performing of assembly activities in two scenarios - ergonomic and non-ergonomic. The non-ergonomic scenario involves performing assembly activities at a traditional workstation. On the other hand, in the ergonomic scenario, participants perform assembly activities on the proposed ergonomically designed workstation, in the golden zone and in this way bending, stress and stretching of the body are eliminated.
