Can beliefs about musculoskeletal pain and work be changed at the national level?
Prospective evaluation of the Danish national Job & Body campaign Using a mixture of networking activities, workplace visits and a mass media campaign, the Danish national Job & Body health campaign improved beliefs about musculoskeletal pain and work among public-sector employees in Denmark. Intensive and long-term national campaigns may be a strategically important tool against musculoskeletal disorders and their consequences in the population. Source: Andersen, L.

Effects of prolonged microscopic work on neck and back strain amongst male ENT clinicians and the benefits of a prototype postural support chair
Musculoskeletal pain is a common occupational hazard experienced by surgeons. Otologists are predisposed to neck and back pain due to regular prolonged microscopic work. We conducted a prospective pilot study to investigate the effects of sustained microscopic work on the neck and back, its correlation to surgical experience and to assess the benefits of a prototype postural support chair (PSC) amongst 10 male ear, nose and throat (ENT) clinicians. We used a subjective measure of time to fatigue and pain for the neck and back as well as objective readings from a surface electromyogram (sEMG). We...
Is objectively measured sitting at work associated with low back pain?
A cross sectional study in the DPhacto cohort Objectives: Low-back pain (LBP) is a substantial health challenge due to the risk for long-term sickness absence and early retirement. Several biomechanical exposures at work, including sitting, have been suggested to increase the risk for LBP. The objectives of this study were to determine (i) the extent to which temporal patterns and total amount of objectively measured sitting is associated with LBP intensity and (ii) whether selected modifiers influence these associations. Methods: This cross sectional study uses baseline data from the Danish PHysical...
Temporal relationships between job strain and low-back pain
To our knowledge this is one of the first studies to examine reciprocal relationships between job strain and back pain and which accounts for time-invariant characteristics. The study highlights a need for more work to establish if there are bidirectional relationships, with more frequent repeat measurements and which account for time-stable individual factors.

Les lombalgies liées au travail
Les lombalgies représentent aujourd'hui 20 % des accidents du travail : c'est le chiffre révélé par une étude inédite de l'Assurance Maladie - Risques professionnels. Le nombre des lombalgies d'origine professionnelle ne diminue pas depuis dix ans en dépit de la baisse de la sinistralité. Elles coûtent près d'un milliard d'euros par an, soit l'équivalent du coût des autres troubles musculo-squelettiques (TMS). Certains secteurs d'activité présentent un sur-risque en matière...
Pushing and pulling: An assessment tool for OHS practitioners
A tool has been developed for supporting practitioners when assessing manual pushing and pulling operations based on an initiative by two global companies in the manufacturing industry. The aim of the tool is to support occupational health and safety practitioners in risk assessment and risk management of pushing and pulling operations in the manufacturing and logistics industries. It is based on a nine-multiplier equation that includes a wide range of factors affecting an operator's health risk and capacity in pushing and pulling. These multipliers are based on psychophysical, physiological...
A multi-component patient-handling intervention improves attitudes and behaviors for safe patient handling and reduces aggression experienced by nursing staff
A controlled before-after study This study evaluated an intervention for patient-handling equipment aimed to improve nursing staffs' use of patient handling equipment and improve their general health, reduce musculoskeletal problems, aggressive episodes, days of absence and work-related accidents. As a controlled before-after study, questionnaire data were collected at baseline and 12-month follow-up among nursing staff at intervention and control wards at two hospitals. At 12-month follow-up, the intervention group had more positive attitudes towards patient-handling equipment and increased...
Effectiveness of multifaceted implementation strategies for the implementation of back and neck pain guidelines in health care
A systematic review For the optimal use of clinical guidelines in daily practice, mere distribution of guidelines and materials is not enough, and active implementation is needed. This review investigated the effectiveness of multifaceted implementation strategies compared to minimal, single, or no implementation strategy for the implementation of non-specific low back and/or neck pain guidelines in health care.

Does objectively measured daily duration of forward bending predict development and aggravation of low-back pain
A prospective study OBJECTIVES: The aim of this paper was to investigate if objectively measured daily duration of forward bending of the trunk increases the risk of the development or aggravation of low-back pain (LBP) over one year in a working blue-collar population by examining (i) the incidence rate of LBP among workers reporting no LBP at baseline, and (ii) the aggravation of LBP among workers reporting LBP at baseline. METHODS: Using data from the Danish Physical Activity Cohort with Objective Measurements (DPhacto), the study measured forward bending of the trunk (>60 ) at work (FBW...
A multi-faceted workplace intervention targeting low back pain was effective for physical work demands and maladaptive pain behaviours, but not for work ability and sickness absence
Stepped wedge cluster randomised trial Aims: The aims of this study were to test whether a multi-faceted intervention effective for low back pain was effective for physical capacity, work demands, maladaptive pain behaviours, work ability and sickness absence due to low back pain. Methods: A stepped wedge cluster randomised, controlled trial with 594 nurses' aides was conducted. The intervention lasted 12 weeks and consisted of physical training (12 sessions), cognitive behavioural training (two sessions) and participatory ergonomics (five sessions). Occupational lifting, fear avoidance, physical...
Temporal patterns of sitting at work are associated with neck–shoulder pain in blue-collar workers
A cross-sectional analysis of accelerometer data in the DPHACTO study BACKGROUND: Our aim was to examine the extent to which temporal patterns of sitting during occupational work and during leisure-time, assessed using accelerometry, are associated with intense neck-shoulder pain (NSP) in blue-collar workers. METHODS: The population consisted of 659 Danish blue-collar workers. Accelerometers were attached to the thigh, hip, trunk and upper dominant arm to measure sitting time and physical activity across four consecutive days. Temporal sitting patterns were expressed separately for work and leisure...
Effectiveness of workplace interventions in the prevention of upper extremity musculoskeletal disorders and symptoms
An update of the evidence The burden of disabling musculoskeletal pain and injuries (musculoskeletal disorders, MSDs) arising from work-related causes in many workplaces remains substantial. There is little consensus on the most appropriate interventions for MSDs. Our objective was to update a systematic review of workplace-based interventions for preventing and managing upper extremity MSD (UEMSD). We followed a systematic review process developed by the Institute for Work & Health and an adapted best evidence synthesis. 6 electronic databases were searched (January 2008 until April 2013 inclusive...
Systematic review of biochemical biomarkers for neck and upper-extremity musculoskeletal disorders
Objective: This study systematically summarizes biochemical biomarker research in non-traumatic musculoskeletal disorders (MSD). Two research questions guided the review: (i) Are there biochemical markers associated with neck and upper-extremity MSD? and (ii) Are there biochemical markers associated with the severity of neck and upper-extremity MSD? Methods: A literature search was conducted in PubMed and SCOPUS, and 87 studies met primary inclusion criteria. Following a quality screen, data were extracted from 44 articles of sufficient quality. Results: Most of the 87 studies were cross-sectional...
A Tailored Workplace Exercise Program for Women at Risk for Neck and Upper Limb Musculoskeletal Disorders

This study aims to investigate the prevalence of WMSDs and identify potential risk factors associated with their occurrence in the dental profession in China. SETTING AND PARTICIPANTS: A cross-sectional survey was carried out in 52 different hospitals in a large metropolitan city in China. A total of 304 questionnaires were distributed...
Barriers to change in depressive symptoms following multidisciplinary rehabilitation for whiplash
The role of perceived injustice OBJECTIVE: Depressive symptoms complicate patients' recovery following musculoskeletal injury. There is strong evidence to support the utility of multidisciplinary approaches for treating comorbid pain and depressive symptoms. Despite this, a significant proportion of patients may not experience meaningful reductions in depressive symptoms following intervention. The purpose of this study was to identify barriers to change in depressive symptom during multidisciplinary rehabilitation for patients with whiplash injuries. METHODS: 53 patients with clinically meaningful...
Declining rates of work-related overexertion back injuries among union drywall installers in Washington State, 1989-2008
Improved work safety or shifting of care? INTRODUCTION: Construction workers are at high risk of work-related musculoskeletal back disorders, and research suggests medical care and costs associated with these conditions may be covered by sources other than workers' compensation (WC). Little is known about the back injury experience and care seeking behavior among drywall installers, a high-risk workgroup regularly exposed to repetitive activities, awkward postures, and handling heavy building materials. METHODS: Among a cohort of 24,830 Washington State union carpenters (1989-2008), including...
