Effects of training to implement new tools and working methods to reduce knee load in floor layers

Exposure assessment of kneeling work activities among floor layers

“…Gluing and crawling work positions occupy a substantial part of the day for floor layers, and the current study highlights the need for modifications of kneeling work positions in the name of prevention of knee injuries. Focusing on new working methods that minimise the risk of knee strains is one of the possibilities (Jensen and Friche, 2007).…”

Exploring physical exposures and identifying high-risk work tasks within the floor layer trade

“…Jensen and colleagues have spent more than 10 years conducting studies with floor layers and through their work they have demonstrated an association between osteoarthritis and other knee disorders to squatting and kneeling postures (Jensen, 2005, 2000a; Rytter et al, 2009a, 2009b, 2008). Their recent work has explored interventions that allow work to be performed from an upright position such as using a stand-up trowel to spread adhesive and floor leveler (Jensen et al, 2010b; Jensen and Friche, 2008, 2007). Upright postures relieve stress on the knee and correct low back flexion and may improve awkward postures of the upper extremity.…”

Workplace intervention and musculoskeletal disorders: the need to develop research on implementation strategy

“…The authors demonstrate that implementation of new working methods requires a long-term structured approach to both implementation and prevention strategies in MSDs. Their intervention consisted of providing new working tools to allow performance of tasks in an upright posture to reduce the time spent in a kneeling position,6 which they hypothesised would reduce knee disorders. The implementation strategy followed a complex process including scientific research, information for employees, employers and trade unions, training, and participatory ergonomics with direct involvement of workers to develop and implement new working methods for floor layers 5 6.…”
