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 in Iran. The prevalence of MSS, particularly in the knees, neck, low back and shoulders was relatively high. Work-related factors including time spent on surgeries each week, number of hours working in standing position per day, moderate to high levels of work–family conflict, duration of each surgery, number of years worked as a surgeon and surgical specialty (particularly cardiothoracic and obstetric/gynecologic surgeries) were independently associated with the presence of MSS in different body regions. Individual factors including gender (being female) and little or no involvement in sport and physical activity were also independently associated with the occurrence of complaints. Implications of the findings for further research and development work for improving the working conditions and consequently reducing MSS among this working group are discussed.

JOURNÉE THÉMATIQUE À VENIR – Tenir compte des contraintes organisationnelles et psychosociales du travail dans la prévention des TMS : une formule gagnante!
Cette journée thématique portera sur la présence de contraintes organisationnelles ou psychosociales du travail, en interaction avec les contraintes physiques ou biomécaniques, entraîne pour les travailleurs exposés des risques plus élevés de troubles musculo-squelettiques (TMS) selon de nombreuses études scientifiques. Ces contraintes concernent principalement une charge de travail élevée, une latitude décisionnelle faible, des relations sociales au travail difficiles ou encore l’absence de mécanismes de reconnaissance des travailleurs par l’organisation. Or, ces risques organisationnels et psychosociaux sont potentiellement identifiables et modifiables. Il demeure toutefois une absence de consensus sur la façon d’en tenir compte dans le cadre de la prévention des TMS liés au travail. La journée permettra aux participants d’explorer la valeur ajoutée de la prise en compte des contraintes organisationnelles et psychosociales du travail en plus des contraintes physiques dans un cadre d’intervention visant à prévenir les TMS.

Conception des équipements de travail et prévention des TMS: Complémentarités et points d’ancrage des démarches
Après un bref rappel sur les démarches de prévention des TMS et de conception des équipements de travail, cet article présente dans un premier temps les difficultés constatées vis-à-vis de leur articulation. Il propose ensuite des « points d’ancrage » pour accompagner, dans un cadre participatif et multidisciplinaire, les temps de recherche de solutions et de décisions. Cette approche doit permettre aux petites et moyennes entreprises (PME) de trouver des réponses à leurs besoins en matière de prévention des TMS très en amont dans le processus de conception d’un équipement de travail. Elle contribue en effet à une meilleure compréhension des leviers favorisant la prise en compte des TMS et à l’élaboration de nouvelles références d’actions vis-à-vis du processus de conception.

Is objectively measured sitting at work associated with low back pain? A cross sectional study in the DPhacto cohort
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. The results showed that sitting was not independently associated with peak LBP intensity, suggesting other exposures are more powerful risk factors for LBP.

An Inspection Tool and Process to Identify Modifiable Aspects of Acute Care Hospital Patient Care Units to Prevent Work-Related Musculoskeletal Disorders
The goal of this study was to describe the development and application of an inspection tool and a process for identifying hazards inherent in the modifiable aspects of the physical environment to reduce injury risk to hospital workers. Through an iterative and participatory process, the tool and inspection process were developed with three purposes in mind: (a) create a framework for the inspection of physical work environments and physical conditions of work associated with injury risk (hazards), (b) document the physical conditions, and (c) provide feedback to decision makers. The tool and process were used by an ergonomics researcher on four patient care units as part of the Be Well, Work Well Total Worker Health® intervention.

Chronotype, Sleep Characteristics, and Musculoskeletal Disorders Among Hospital Nurses
Work-related musculoskeletal disorders (WMSDs) persist as the leading occupational injury, accounting for nearly half of nurses’ total occupational injuries. Musculoskeletal pain is a known cause of sleep disruption, and individuals with WMSDs that interfere with sleep often report more pain. Evening chronotype has been associated with poor sleep among nurses. However, the associations among chronotype, sleep, and WMSDs are still unclear, and were explored in the present study. This study suggests that well-designed evidence-based non pharmacological interventions to improve sleep may reduce the risk of WMSDs among nurses.

Nature of Injury and Risk of Multiple Claims Among Workers in Manitoba Health Care
In industrial societies, work-related musculoskeletal disorders are common among workers, frequently resulting in recurrent injuries, work disability, and multiple compensation claims. The risk of idiopathic musculoskeletal injuries is thought to be more than twice the risk of any other health problem among workers in the health care sector. This risk is highly prevalent particularly among workers whose job involves frequent physical tasks, such as patient lifting and transfer. Workers with recurrent occupational injuries are likely to submit multiple work disability claims and progress to long-term disability. The objective of this study was to explore the influence of injury type and worker characteristics on multiple compensation claims, using workers’ compensation claims data. This retrospective study analyzed 11 years of secondary claims data for health care workers.

Nurses’ Perceptions of Their Foot Health: Implications for Occupational Health Care
Nursing practice includes static standing and much walking causing strains to lower extremities. However, little is known about nurses’ foot health and particularly their perceptions of their foot health. Therefore, in this study operating room nurses’ perceptions of their foot health was investigated and promoting and hindering factors were identified. In total, 14 operating room nurses participated in in-depth interviews. The informants regarded foot health as part of general health and moreover a significant part of work well-being. Promoting factors for foot health were activity in sports and foot self-care as well as varying work conditions and seeing patients with severe foot conditions which served as a motivating factor to care for their own feet. On the contrary, hindering factors were unsuitable footwear, constant standing, and lack of motivation to care for their own feet. Based on this study, nurses’ value their foot health which should be promoted. Nurses could benefit from annual foot health assessments and foot self-care education provided by occupational health professionals.

Saddle Seat Reduces Musculoskeletal Discomfort in Microsurgery Surgeons
Microsurgery is a surgical procedure that requires a high degree of precision and is commonly facilitated through the use of an intraoperative microscope. When operating the microscope system, the long-term posture and stance lead to fatigue and musculoskeletal disorders in surgeons, and seats are commonly employed to diminish these problems. The present study was conducted to evaluate musculoskeletal discomfort during work with a saddle seat especially designed for people using intraoperative microscopes in comparison with conventional seats for microscopic works. The authors found that the highest amount of discomfort that microsurgical surgeons acquire in the workplace was focused on their neck, shoulder, arm and back, respectively. During the work with a saddle seat, a significant reduction was found for discomfort values in neck, shoulder, arm, back, elbow and forearm, as well as the whole body. Over 89 percent of the participants said that the use of this seat causes increased comfort during operation.

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. This prospective pilot study 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). It was found that an increase in surgical experience correlated with the time taken to experience fatigue and pain in the neck and back.

Changing Your Work Environment to Reduce Ergonomic Injuries
According to the National Institute for Occupational Safety and Health (NIOSH), around 20 percent of days of missed work are due to injuries that happen as a result of poor office design. Companies that consider their employees’ work environment and how it can affect health and efficiency potentially can reduce workplace injuries. Most organizations see the frequency of ergonomic-related injuries and costs grow each year. The simple fact is that people need to perform physical work, whether at a factory, store or an office. Finding good workers is half the battle. Now, you need to keep them healthy and productive.

Application des pratiques préventives par les infirmières et infirmiers: La perspective innovante de la capacité d’absorption
Plusieurs obstacles entravent l’application des bonnes pratiques de prévention des TMS chez le personnel du secteur des soins de santé. C’est ce que démontre une étude dont l’objet était de comprendre les raisons pour lesquelles le personnel infirmier subit encore des TMS alors que les données probantes pour mieux les prévenir sont facilement accessibles. Ces barrières se situent à l’étape de l’application des connaissances et non de l’acquisition ou de l’appropriation de celles-ci, ce qui suggère qu’elles relèvent davantage des milieux de travail. Parmi celles-ci, on trouve: le décalage entre les conditions d’application des mesures préventives lors des formations et celles en milieu de travail; les difficultés d’accès aux équipements de manutention; une culture qui valorise peu les comportements sécuritaires. L’étude suggère notamment de mieux sensibiliser les cadres à l’intégration des pratiques préventives aux routines organisationnelles, d’offrir davantage de formation adaptée au contexte de chaque établissement et la possibilité de pratiquer les techniques de manipulation sur les lieux de travail.

DOSSIER – Travailler dans un bureau: des risques à ne pas sous-estimer
En réponse à de nouvelles méthodes managériales, nombre d’entreprises opèrent une mutation des espaces de travail et, plus largement, une révolution du travail au bureau. Mais les innovations architecturales et la multiplication des moyens de communication sont-elles nécessairement gage d’amélioration des conditions de travail? Car les risques existent pour le salarié. Qu’ils soient liés aux ambiances physiques de travail (qualité de l’air et ambiance thermique, bruit, éclairage…), à l’organisation de l’espace ou aux nouveaux modes de communication, ils ne doivent pas être occultés. Ce dossier brosse un état des lieux des évolutions en cours du travail au bureau, des risques qu’elles engendrent et que toute entreprise devrait intégrer afin de penser des espaces capables de répondre aux contraintes socio-économiques, d’améliorer la productivité tout en offrant de réelles améliorations des conditions de travail.
