Association between Assembly Work Electromyography and Discomfort as Identified by Video-Computer Interaction

The purpose of this product is to study the correlation between self-reported and measured mechanical workload of neck and shoulder on workstations level. Six persons participated in the study, each working at six different workstations. The workstations were ranked from “lowest” to “highest” workload according to different variables. The correlations were studied on ranking order. Different types of assembly work were mainly carried out in all stations. In this work (few high workload situations, and a high degree of monotonous, repetitive work situations) one situation with a high workload could in this case be experienced as positive. The methods lead to contradicting results as regards identifying work situations with high loads. The results indicate that the methods lead to similar results as regards identifying work situations with low loads.
