The effectiveness of participatory ergonomics to prevent low-back and neck pain – results of a cluster randomized controlled trial

Does body posture during tree felling influence the physiological load of a chainsaw operator? Ann Agric Environ Med. 2017; 24(3): 401-405. doi: 10.5604/12321966.1235177 Abstract Introduction and Objectives. Holding determined body postures during work is connected with muscles activity. The more forced the posture, the larger the number of muscles taking an active part in holding and stabilizing the work posture. During logging, the greatest share of awkward (forced) working postures occurs in tree felling by chainsaw. Materials and Method. A group of 10 experienced fellers aged 47.5±7.3 (37 -59-years-old) was studied. Heart rate (HR) was measured during simulation of felling activity in 4 working postures: back bent forward with straight legs (stoop), back bent forward with bent legs (flexed-stoop), squat and kneeling on one knee (half-kneel). Results. The lowest value of HR was noticed for squatting -114.1 bpm, then for kneeling on one knee -116.3 bpm. HR during felling in a standing posture with straight legs amounted to 121.5 bpm and for standing with bent legs 125.3 bpm. For all studied postures the differences in average HR values were statistically significant at p<0.01. Conclusions. A working posture during tree felling by chainsaw has influence on the level of physiological workload of an operator. Standing bent forward body postures cause higher heart response than squatting and half-kneeling.

Little was known about the effectiveness of organizational or psychosocial work interventions to prevent work-related musculoskeletal disorders (MSD). We found moderate evidence of the effectiveness of supplementary rest breaks. We also identify key elements of ergonomic interventions lacking in the interventions reviewed that, if integrated into future studies and shown to be effective, may lead to advances in MSD prevention.

“…In the previous decades there has been an increase in the number of studies regarding primary prevention of MSD, across a wide range of scientific disciplines, including epidemiology (29), applied physiology (30), biomechanics (31), physical and organizational (macro) ergonomics (25,32), behavioral sciences (33), production engineering (34), organizational management (35), health and business economics (36), and implementation science (37). These disciplines vary largely in their contribution to work-related MSD prevention research, ranging from classic injury surveillance and etiological studies to detailed laboratory studies and animal models exploring injury mechanisms, and studies evaluating interventions and implementation.…”

We are the first to describe a research framework for prevention of work-related musculoskeletal disorders (MSD) in which different research disciplines are linked. This framework can help to improve theories and strengthen the development and implementation of prevention strategies for work-related MSD. Original article Scand J Work Environ Health. 2017;43(6):526-539. doi:10.5271/sjweh.3671 A research framework for the development and implementation of interventions preventing work-related musculoskeletal disorders Objectives Work-related musculoskeletal disorders (MSD) are highly prevalent and put a large burden on (working) society. Primary prevention of work-related MSD focuses often on physical risk factors (such as manual lifting and awkward postures) but has not been too successful in reducing the MSD burden. This may partly be caused by insufficient knowledge of etiological mechanisms and/or a lack of adequately feasible interventions (theory failure and program failure, respectively), possibly due to limited integration of research disciplines. A research framework could link research disciplines thereby strengthening the development and implementation of preventive interventions. Our objective was to define and describe such a framework for multi-disciplinary research on work-related MSD prevention. Affiliation MethodsWe described a framework for MSD prevention research, partly based on frameworks from other research fields (ie, sports injury prevention and public health). ResultsThe framework is composed of a repeated sequence of six steps comprising the assessment of (i) incidence and severity of MSD, (ii) risk factors for MSD, and (iii) underlying mechanisms; and the (iv) development, (v) evaluation, and (vi) implementation of preventive intervention(s). ConclusionsIn the present framework for optimal work-related MSD prevention, research disciplines are linked. This framework can thereby help to improve theories and strengthen the development and implementation of prevention strategies for work-related MSD.
