Table 2.

The median (M) values in accumulated time in dominant upper-arm elevations ≥30°, ≥45°, and ≥60°, and the 50th, 90th, 95th, and 99th percentile dominant upper-arm elevation angles of the baseline and workstation design (WS-Design) scenario. The proportional differences (diff) of the values obtained in the workstation design sessions 1–3 when compared to the baseline value, where significant differences (p < 0.01, Wilcoxon signed-rank test) are displayed in bold.
