“…These lower ratings of exertion can probably be explained by the fact that the postures were more convenient, because cleaners were able to work with their arms at a lower level without elevating their shoulders. Similarly, with regard to staircase cleaning the favourable impact of adjustment of the mop on perceived effort and muscular load has previously been reported 19 ) .…”

“…Only a limited number of studies have evaluated the effect of adjustment of mop handle on shoulder muscle load. A study of Öhrling et al 19 ) found that in staircase mopping the shoulder muscular activity and perceived exertion were lower when an easily adjustable mop handle was used, compared to a non-adjustable mop. However, it is uncertain whether the high shoulder muscle load during mopping with a figure eight method is partly due to the use of a too-long mop handle.…”

The aim of this study was to investigate effects of mop handle height on electromyographic (EMG) activities of the shoulder muscles and perceived exertion for the shoulder area during floor mopping using a figure eight method. An experimental study with 13 cleaners was conducted using surface EMG and category ratio (CR-10) scale. EMG activity was recorded unilaterally from the upper trapezius, infraspinatus, anterior and middle deltoid muscles. Each subject performed four trials of mopping and each trial consisted of using a different mop handle height (mop adjustment at the level of shoulder, chin, nose and eye) in randomized order. EMG data were normalized to a percentage of maximal voluntary contraction (%MVC). The muscle activities were assessed by estimating the 10th, 50th and 90th percentiles of the amplitude probability distribution function (APDF) of the EMG signals and analysed by linear mixed model analysis. Results showed that shoulder muscle activity was significantly lower when the mop handle height was adjusted to shoulder level or chin level as compared to eye level. These ﬁndings were supported by subjective ratings of exertion. It seems that mop handle height adjustment between shoulder and chin level may be recommended as a basis for figure eight mopping.

“…All studies except one (Conner & Irwin, 2009) involved a majority of female cleaning professionals. However, two studies did not report the gender of participants (Kumar, Hägg, & Öhrling, 2008; Öhrling, Kumar, & Abrahamsson, 2012).…”

“…Those factors that have yielded positive results belong to the following major categories of strategies: (a) mop design (Conner & Irwin, 2009; Öhrling et al, 2012; Wallius et al, 2016), (b) mopping methods (Hopsu et al, 2000), (c) mopping technique (Hagner & Hagberg, 1989), and (d) work environment modifications (Kumar et al, 2005a).…”

An Overview of Strategies for Reducing Upper Extremity Physical Exposure Associated With Floor Mopping: A Systematic Review

et al. 2018

View full text Add to dashboard Cite

Objective: This systematic review synthesizes literature on upper extremity physical exposure associated with floor mopping, in order to (a) assess the impact of changes in mopping systems on physical exposure and (b) propose recommendations for strategies to reduce exposure. Background: Floor-cleaning tools and equipment have undergone major improvements. Existing studies have focused on mop design modifications and cleaning efficiency. However, less is known about strain responses caused by modern tools and methods. Method: Studies from 1987 to February 2017 were identified by electronic and manual search. All selected studies underwent a quality assessment. The evidence was organized into categories representing different strategies for reducing exposure. The levels of evidence were determined using a best evidence synthesis approach. Results: Eleven studies were included. Based on the review findings, currently there is moderate evidence suggesting that reduced physical exposure has been achieved through development of mopping systems. Levels of evidence for strategies associated with positive effects on physical exposure were: moderate evidence for mop design and handle type, insufficient evidence for mopping technique, and mixed evidence for mopping methods and environment modifications. Therefore, the present study suggests the use of adjustable mop handles as a strategy for reducing physical exposure. Conclusion: A more comprehensive approach to reducing physical exposure concerning floor mopping work is necessary. Application: Knowledge regarding physical exposure reduction can be applied as the basis for decision making in cleaning practice. Information can be incorporated into future research regarding development of floor-cleaning methods.
