Cardiovascular load assessment in the workplace: A systematic review
2023, International Journal of Industrial ErgonomicsTrapezius muscle activity variation during computer work performed by individuals with and without neck-shoulder pain
2019, Applied ErgonomicsCitation Excerpt :In this context, exposure variation analysis (EVA) (Mathiassen and Winkel, 1991) is a tool that expresses continuous exposure-vs-time data in categories defined by exposure amplitude and accumulated time, thus giving way to an understanding of the differences in the temporal structure of exposures at different amplitude levels. EVA has been shown in studies of muscle activity, in particular in the upper trapezius, to be sensitive in various tasks outside computer work (Attebrant et al., 1997; Bao et al., 1996; Delisle et al., 2005; Fjellman-Wiklund et al., 2004; Januario et al., 2018; Mathiassen and Winkel, 1996; Reynolds et al., 2014). Specifically with regard to upper trapezius muscle activity during computer work, EVA has been shown to be sensitive to variation in task (Ciccarelli et al., 2013; Jensen et al., 1999; Mathiassen et al., 2003; Straker et al., 2009; Wærsted and Westgaard, 1997), demographic groups (pain, age and pregnant vs. non-pregnant) (Dumas et al., 2008; Hägg and Åström, 1997; Maslen and Straker, 2009), and configuration of work environment (Dumas et al., 2009; Samani et al., 2009a, 2009b).
Trunk posture assessment during work tasks at a Canadian recycling center
2018, International Journal of Industrial ErgonomicsCitation Excerpt :This finding was similar to other industrial workers’ studies that have been conducted. For instance, sewing machine assemble workers had a median 50th percentile flexion/extension angle of 14° (BaoM. S. E and Winkel, 1996), material pickers in car assembly workers 14° (Christmansson et al., 2002), and craft-type car disassembly workers 10.1° (Kazmierczak et al., 2005). The 90th percentile is frequently used as an estimate of peak exposures encountered during a task or work shift (Kazmierczak et al., 2005), (Trask et al., 2006).
New easy to use postural assessment method through visual management
2016, International Journal of Industrial ErgonomicsCitation Excerpt :Excessive standing may also cause the joints in the spine, hips, knees and feet to become stiff or locked (Balasubramanian et al., 2009). Bao et al. (1996) followed optimization and rationalization processes of a big production firm dealing with ergonomics of production processes. Their aim was to evaluate the ergonomic impact of workloads before the planned improvements and to compare them with the future state of the line.
