Acute Effects of Interrupting Sitting on Discomfort and Alertness of Office Workers
Objective: The aim of this study was to compare the effect of 4 hours of sitting interrupted with hourly bouts of standing and/or pedaling versus uninterrupted sitting on alertness and discomfort among sedentary office workers. Methods: Fifteen middle-aged sedentary workers were randomized to three 4-hour conditions: (1) uninterrupted sitting; (2) sitting interrupted with 10 minutes of standing/hour; and (3) sitting interrupted with 10 minutes of pedaling/hour. Self-reported measures of alertness and discomfort were collected. Results: Uninterrupted sitting significantly increased discomfort (P...
Ergonomic interventions for preventing work-related musculoskeletal disorders of the upper limb and neck among office workers
Work-related upper limb and neck musculoskeletal disorders (MSDs) are one of the most common occupational disorders worldwide. Studies have shown that the percentage of office workers that suffer from MSDs ranges from 20 to 60 per cent. The direct and indirect costs of work-related upper limb MSDs have been reported to be high in Europe, Australia, and the United States. Although ergonomic interventions are likely to reduce the risk of office workers developing work-related upper limb and neck MSDs, the evidence is unclear. This is an update of a Cochrane Review which was last published in 2012...
Évaluation des processus : comprendre comment le contexte des entreprises influence le déroulement des premières étapes d’interventions ergonomiques
Bien qu'il soit généralement convenu que les ergonomes adaptent leur intervention au contexte de chaque entreprise, la façon précise dont ils y parviennent et sur quels critères cette adaptation se base sont peu renseignés au plan scientifique. Une évaluation des processus a été réalisée en adoptant un devis d'étude de cas multiple, en vue d'identifier les indicateurs de contexte ayant influencé quatre interventions du courant de l'ergonomie de l'activité, réalisées...

Intervention, conception et transformations : comment construire une prévention durable des TMS
Cet article a pour but de participer aux réflexions sur le rôle de l'ergonome dans l'intervention en entreprise. Il présente une intervention-formation relative à la prévention de la pénibilité et des TMS au travail. Cette intervention, menée comme une conduite de projet, s'est basée sur l'adoption de principes fondamentaux pour l'ergonomie dite centrée sur l'activité (Daniellou & Rabardel, 2005). Ces principes portent sur (1) la conception et la pérennisation des démarches de prévention...

What do Workers do to Reduce Their Sitting Time?
The Relationships of Strategy use and Workplace Support with Desk-Based Workers' Behaviour Changes in a Workplace-Delivered Sitting-Reduction and Activity-Promoting Intervention Objective: To explore workers' sitting-reduction and activity-promoting strategy use following an intervention targeting these changes, and whether strategy use and perceived workplace support impacted on three-month sitting and activity outcomes. Methods: This secondary analysis in desk-based workers (n = 83) utilised data collected on questionnaire-derived strategy use and workplace support, and activPAL3TM-derived...
Conceptual frameworks for the workplace change adoption process
Elements integration from decision making and learning cycle process Sound workplace ergonomics and safety-related interventions may be resisted by employees, and this may be detrimental to multiple stakeholders. Understanding fundamental aspects of decision-making, behavioural change, and learning cycles may provide insights into pathways influencing employees' acceptance of interventions. This manuscript reviews published literature on thinking processes and other topics relevant to decision making and incorporates the findings into two new conceptual frameworks of the workplace change adoption...
Pour quelles raisons la formation aux techniques sécuritaires de manutention ne fonctionne-t-elle pas?
Revue critique de la littérature La formation en manutention fait l'objet de nombreuses demandes de la part des milieux de travail. Or, malgré leur abondante diffusion, ces formations voient leur efficacité remise en cause par cinq méta-analyses publiées entre 2007 et 2014. La consultation de ces revues de la littérature ne permet pas de comprendre les raisons pour lesquelles il en est ainsi puisque les formations recensées – et dont on tente d'évaluer l'efficacité – n'y sont pas décrites, ou alors...

In phase two, relevant randomised controlled trials and cluster randomised controlled trials...
Work-related physical, psychosocial and individual factors associated with musculoskeletal symptoms among surgeons
Implications for ergonomic interventions This study evaluated the effect of physical, psychosocial and individual factors on the presence of musculoskeletal symptoms (MSS) among surgeons (n = 312) in Iran. Data were collected using questionnaires and analysed by multivariate logistic regression. The prevalence of MSS, particularly in the knees (48.7%), neck (45.8%), low back (42.3%) and shoulders (40.1%) was relatively high. Work-related factors including time spent on surgeries each week (>25 h/week), number of hours working in standing position per day (>4 h/day), moderate to high levels...
Return on investment of interventions for the prevention and treatment of musculoskeletal
There were two key objectives for the work: - To conduct a literature review to identify which interventions are cost-effective in reducing the complications associated with osteoarthritis of the hip or knee, neck pain or back pain; - To develop an ROI tool that allows the resource and financial consequences of implementing these cost-effective interventions nationally and at local levels.

Total Worker Health® Concepts to Reduce the Health Risks from Sedentary Work
U.S. workplaces have become increasingly sedentary, with resulting negative health effects. Through its Total Worker Health® Program, the National Institute for Occupational Safety and Health (NIOSH) recommends an integrated approach to addressing sedentary work environments. An integrated approach is one that protects workers from work-related injury and illness and helps them advance their overall health and well-being, on and off the job. This document describes organizational practices that can reduce the risks associated with sedentary work. Source: https://www.cdc.gov/niosh/docs/wp-solutions...
Injury rates before and after the implementation of a safe resident handling program in the long-term care sector
Manual resident handling (RH) tasks increase risk of musculoskeletal disorders (MSDs) for clinical staff in nursing homes. To reduce the incidence and cost of MSDs, a large healthcare corporation instituted a Safe Resident Handling Program (SRHP) comprising purchase of mechanical lifting equipment, worker training, and detailed usage/maintenance protocols. The program was initially administered by a third-party company; after three years, program responsibility shifted to individual centers. Workers' compensation claim rates were compared before and after SRHP implementation. Claims and FTEs...

Methods We searched electronic databases from 1990 to 2012. Random pairs of independent reviewers critically appraised eligible studies using the Scottish Intercollegiate Guidelines Network criteria. Scientifically admissible studies were summarized...
Performing Artists, Part 2
Work: A Journal of Prevention, Assessment and Rehabilitation . Volume 41, Number 1 / 2012 Performing arts health (PAH) as a field of research may be relatively unknown to some readers. It is my intent in this second editorial, therefore, to highlight some of the similarities and differences between this field and the field of work disability (WD), broadly construed (as in this journal) to include prevention, assessment and rehabilitation. Readers will be familiar with the significant economic and societal burden of work-related health concerns. In 1999, the World Health Organization (WHO) estimated...
Manual Handling Risks Grab Irish Authority's Attention
A new guidance document published by the Health and Safety Authority recommends ways to prevent back injuries and strains caused by handling heavy loads or lifting loads to an unsafe height. Ireland's Health and Safety Authority has posted a guidance document to help retail establishments prevent back injuries and strains that could result from manual handling of pallets, heavy boxes, and bulky consumer products at point of purchase, such as cases of bottled water. The agency noted that some work at retail establishments may involve a significant amount of physical activity, which can be hazardous...
