Pratique d’exercices physiques au travail et prévention des TMS
Revue de la littérature Les troubles musculosquelettiques (TMS) sont à l'origine d'une sinistralité très élevée et les entreprises se sentent parfois démunies face à ce problème. La tentation est grande aujourd'hui d'orienter les efforts de prévention vers une approche individuelle. Les entreprises sont très fréquemment sollicitées par des intervenants extérieurs qui leur proposent d'instaurer des programmes d'échauffements, d'étirements, d'exercices de...
Exercise for the Prevention of Low Back Pain
Systematic Review and Meta-Analysis of Controlled Trials The aim of this systematic review and meta-analysis was to assess the effect of exercise in population-based interventions to prevent low back pain (LBP) and associated disability. Comprehensive literature searches were conducted in multiple databases including PubMed, Embase, and Cochrane Library from their inception through June 2017. Thirteen randomized controlled trials and three non-randomized controlled trials qualified for meta-analyses. Exercise alone reduced the risk of LBP by 33% (risk ratio = 0.67, 95% CI: 0.53, 0.85, I2 = 23%...
The Effect of Intelligent Physical Exercise Training on Sickness Presenteeism and Absenteeism Among Office Workers
Objective: The aim of this study was to investigate the effect of individually tailored intelligent physical exercise training (IPET) on presenteeism and absenteeism among office workers. Methods: In a 1-year randomized controlled trial (RCT), employees were allocated to a training group TG (N = 193) or control group CG (N = 194). TG received 1-hour high-intensity IPET once a week within working hours, and was recommended to perform 30 minutes of moderate-intensity physical activity (PA) 6 days a week during leisure-time. Results: An intention-to-treat analysis showed no effect on absenteeism,...
Decrease in musculoskeletal pain after 4 and 12 months of an aerobic exercise intervention
A worksite RCT among cleaners Background: Prevalence of musculoskeletal pain is high in jobs with high physical work demands. An aerobic exercise intervention targeting cardiovascular health was evaluated for its long term side effects on musculoskeletal pain. Objective: The objective was to investigate if aerobic exercise affects level of musculoskeletal pain from baseline to 4- and 12-months follow-up. Methods: One-hundred-and-sixteen cleaners aged 18–65 years were cluster-randomized. The aerobic exercise group (n = 57) received worksite aerobic exercise (30 min twice a week) and the reference...
Long-term effectiveness of an educational and physical intervention for preventing low-back pain recurrence
A randomized controlled trial This paper notes that a careful case definition of workers with previous history of low-back pain (LBP) is needed to better characterize sub-groups based on their recurrences profile. Workers with highly recurrent LBP may require a stepped secondary prevention in order to prevent recurrences and sick leave. The value of a workplace component reducing physical and psychosocial risks in secondary prevention of LBP must be explored.

The Effects of Workplace Physical Activity Programs on Musculoskeletal Pain
A Systematic Review and Meta-Analysis This article reviews the effectiveness of physical activity (PA) interventions at the workplace to reduce musculoskeletal pain among employees and assesses the effect size of these programs using meta-analysis. Four databases (i.e., PubMed, EBSCO, Web of Science, and Cochrane) were searched for research trials, which included comparison groups of employees that assessed PA programs, musculoskeletal pain, and health-related behaviors, published between January 1990 and March 2013. The meta-analysis estimates of standardized mean differences (Hedges' g) present...
Prevention of Low Back Pain

OBJECTIVE: To investigate the effectiveness of interventions for prevention of LBP. DATA SOURCES: MEDLINE, EMBASE, Physiotherapy Evidence Database Scale, and Cochrane Central Register of Controlled Trials from inception to November 22, 2014. STUDY SELECTION: Randomized clinical trials of prevention strategies for nonspecific LBP. DATA EXTRACTION AND SYNTHESIS: Two independent reviewers extracted data and assessed the risk of bias. The Physiotherapy...
Motor control exercise for chronic non-specific low-back pain
Non-specific low back pain (LBP) is a common condition. It is reported to be a major health and socioeconomic problem associated with work absenteeism, disability and high costs for patients and society. Exercise is a modestly effective treatment for chronic LBP. However, current evidence suggests that no single form of exercise is superior to another. Among the most commonly used exercise interventions is motor control exercise (MCE). MCE intervention focuses on the activation of the deep trunk muscles and targets the restoration of control and co-ordination of these muscles, progressing to more...
Evaluating Abdominal and Lower-Back Muscle Activity While Performing Core Exercises on a Stability Ball and a Dynamic Office Chair
Objective: The purpose of this study was to evaluate the ability of a dynamic office chair to activate the core muscles while participants performed exercises sitting on the chair compared to a stability ball. Background: Prolonged sitting has become an accepted part of the modern office. However, epidemiological evidence suggests that sedentary postures are linked to many adverse effects on health. The concept of dynamic or active sitting is intended to promote movement while sitting to reduce the time spent in prolonged, static postures. Methods: Sixteen participants performed four pelvic rotation...
A multi-faceted workplace intervention for low back pain in nurses' aides
A pragmatic stepped wedge cluster randomised controlled trial The present study established the effectiveness of a workplace multi-faceted intervention consisting of participatory ergonomics, physical training and cognitive behavioural training for low back pain. Between November 2012 and May 2014, we conducted a pragmatic stepped-wedge cluster-randomized controlled trial with 594 workers from eldercare workplaces (nursing homes and home care) randomized to four successive time periods, three months apart. The intervention lasted 12 weeks and consisted of 19 sessions in total (physical training...

Process Evaluation of Workplace Interventions with Physical Exercise to Reduce Musculoskeletal Disorders
Process evaluation is important to explain success or failure of workplace interventions. This study performs a summative process evaluation of workplace interventions with physical exercise. As part of a randomized controlled trial 132 office workers with neck and shoulder pain were to participate in 10 weeks of elastic resistance training five times a week at the workplace; the 2min group performed a single set of lateral raise to failure, and the 12min group performed 5-6 sets with 8–12 repetitions. Participants received a single instructional session together with a training diary and...

Being a natural experiment, the two participating companies implemented and modified the initial training program...
NIOSH Takes a Stand
Over the past year, NIOSH and its Total Worker HealthTM Program have been traveling the country sharing the evidence and benefits of comprehensively integrating health protection with health promotion, including workplace programs that encourage physical activity, weight loss and stress management. Recently, we launched an internal NIOSH pilot program to explore the use of sit and stand work stations as part of a workplace health and wellbeing initiative to reduce sedentary work in our workplace.

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...
Exercises to reduce musculoskeletal discomfort for people doing a range of static and repetitive work
Previous research has recognised exercise as an intervention that may be effective in reducing the occurrence of musculoskeletal disorders (MSDs) amongst the workforce. The aims of this work are to undertake a brief review of literature to identify suggested exercises and any evidence of their benefit with the intention to compile a set of exercises that may be appropriate for inclusion in a leaflet or other publication. Exercices to reduce musculoskeletal discomfort for people doing a range of static and repetitive work. Christine Leah, Health and Safety Laboratory. HSE, 2011. 26 p. (RR743 Research...
Les effets d’un entraînement physique pré-saison sur le travail et la sécurité des débroussailleurs
Étude de faisabilité d'une approche de mesure Depuis quelques années, des intervenants du Bas-St-Laurent (BSL) ont développé et mis en application un Programme d'entraînement physique pour les travailleurs forestiers (PEPTF). Le PEPTF vise à améliorer leur condition physique avant le début de la saison de travail afin de leur faciliter le retour au travail et éventuellement de réduire les accidents du travail et les TMS. Des travaux récents montrent que les débroussailleurs sont soumis à une...
