“…To estimate posture-related load, researchers used measuring instruments such as inclinometers (Åkesson et al, 2012;Hansson et al, 2009Hansson et al, , 2010Hodder et al, 2010;Veiersted et al, 2008), flexometers (Pugh et al, 2019) and goniometers (Åkesson et al, 2012;Le and Marras, 2016), to measure body angulation of people who are working. Also, electromyography (EMG) was used to verify the electric current passing through the muscles (Åkesson et al, 2012;Brandt et al, 2015;Hansson et al, 2009Hansson et al, , 2010Veiersted et al, 2008).…”
