- Group means at the 50th and 90th percentiles of upper arm elevation (°) and the median generalised upper arm angular velocity (°/s) during different types of cleaning when using the standard reference posture as reference. (Data from the four men are excluded). The generalised angular velocity is not dependent on the reference posture. Hotel housekeeping = cleaning hotel rooms, hotel housekeeping+ = cleaning hotel rooms and other tasks such as cleaning corridors. The standard recordings were performed by researchers. Differences calculated by Kruskal-Wallis analysis of variance. Post hoc analysis with Mann-Whitney U-test
- ap = 0.05
