Les conséquences de l’utilisation d‘exosquelettes en termes de sécurité et de santé au travail

Ce document de réflexion examine le rôle que pourraient jouer les exosquelettes dans l'environnement de travail du futur et les possibles incidences de leur utilisation sur la sécurité et la santé des travailleurs. Il examine le rôle que pourraient jouer les exosquelettes dans la prévention des troubles musculo-squelettiques, et se penche sur les risques potentiels de leur application dans différents domaines.
Le document reconnaît l'incertitude qui entoure leurs effets à long terme sur la santé et les difficultés rencontrées pour établir une certification uniforme, et met en évidence la nécessité de réaliser des études plus complètes. L'approche consistant à préférer une hiérarchisation des priorités en matière de prévention lors de la conception des futurs lieux de travail, plutôt que de s'en remettre aux exosquelettes pour créer des environnements de travail ergonomiques, est également abordée.

Workplace Interventions can Reduce Sickness Absence for Persons With Work-Related Neck and Upper Extremity Disorders

A One-Year Prospective Cohort Study
Objective: The objective of this study was to investigate whether workplace interventions are effective in reducing sickness absence in persons with work-related neck and upper extremity disorders and whether disorder improvement after intervention reduces sickness absence.
Methods: This study was a prospective cohort study of workers with work-related neck pain or upper extremity disorders. Data were obtained from the Swedish “Work-related disorders” and “Work environment” surveys. Register data on sickness-absence 1 year after the surveys were made and obtained from the Swedish health insurance database.
Results: A significant lower number of sickness-absence days were found for workers reporting improvement after intervention.
Conclusion: The findings in this study suggest that workplace intervention can reduce sickness absence for workers with neck or upper extremity disorders only if the intervention improves the disorder. The interventions were most effective in reducing medium long sickness absence periods.

Sedentary work and risk of venous thromboembolism

Objective: Prolonged seated immobility during long-distance flights is related to an increased risk of venous thromboembolism (VTE), but little, if anything, is known about the risk related to sedentary work. The objective of this paper was to examine the risk of VTE according to sitting posture at work.
Methods: This prospective study includes a total of 78 936 participants from the Copenhagen City Heart Study and the Copenhagen General Population Study, all without previous thromboembolic events and aged <65 years. An assessment of the number of hours spent in sitting position at work was assigned each participant at Baseline using a job exposure matrix. VTE was identified through national patient registries. Survival analyses were performed to determine the risk of VTE according to sedentary position at work with adjustment for a range of known determinants including lifestyle and coagulation factors.
Results: During the follow-up period of 582 411 person years (mean follow-up, 7.4 years) 911 participants experienced their first VTE event. Multivariable adjusted analyses showed no difference in risk of VTE between
occupational sitting ≥6.5 hours/day and occupational sitting ≤3.5 hours/day (hazard ratio 1.11, 95% confidence interval 0.92–1.34).
Conclusion: This study does not support the hypothesis that sedentary work is a risk factor for VTE in the general population. Whether certain occupations with particularly high exposure to immobilized sitting positions are associated with thromboembolic events is not addressed.

Lanceurs de discussion sur le lieu de travail concernant les troubles musculo-squelettiques

Les lanceurs de discussion peuvent faciliter les débats en groupes sur le lieu de travail ou pendant la formation professionnelle. Les scénarios qui y figurent sont conçus pour les travailleurs réalisant des tâches susceptibles de leur causer des troubles musculo-squelettiques (TMS), ainsi que pour leurs supérieurs hiérarchiques et superviseurs.
Cette ressource répond également à la nécessité d’établir une communication rapide et efficace entre le travailleur et son supérieur concernant un problème de santé lié à des troubles musculo-squelettiques.
