Acceptation des exosquelettes par les opérateurs : étude exploratoire
L'introduction des exosquelettes, comme toute nouvelle technologie, constitue un changement au niveau de l'organisation et de l'activité des opérateurs. C'est dans ce cadre qu'est abordée la question spécifique de l'acceptabilité et de l'acceptation de ces dispositifs par les opérateurs. Pour cela, un questionnaire a été élaboré et administré à des utilisateurs, anciens utilisateurs et nonutilisateurs d'exosquelettes. En termes de santé et sécurité, les résultats...
Anthropometry of the Canadian adult population
Developing comprehensive, updated normative-reference standards Introduction: Applications of structural anthropometric measurements include user-centered design, health risk appraisal and assessment of biological maturity. It is important that anthropometric normative-reference standards are current, comprehensive, and population specific. Previous work by Pheasant (1996) included thirty-six anthropometric measurements to create a comprehensive and comparable list of data. However, Canadian studies have included nineteen or less body dimensions, and relatively small sample sizes. The aims of this...
The effect of a passive trunk exoskeleton on functional performance in healthy individuals
The objective of this study was to assess the effect of a passive trunk exoskeleton on functional performance for various work related tasks in healthy individuals. 18 healthy men performed 12 tasks. Functional performance in each task was assessed based on objective outcome measures and subjectively in terms of perceived task difficulty, local and general discomfort. Wearing the exoskeleton tended to increase objective performance in static forward bending, but decreased performance in tasks, such as walking, carrying and ladder climbing. A significant decrease was found in perceived task difficulty...
Intégrer la prévention des risques professionnels dès la conception des équipements d'aide à la manutention des personnes
Les risques professionnels encourus par les utilisateurs d'équipements d'aide à la manutention des personnes ne sont pas toujours bien pris en compte lors de leur conception. À travers l'exemple du Milo, un équipement d'aide au transfert de personnes et à la toilette, l'INRS a élaboré des recommandations pour intégrer la prévention de ces risques dès la conception des aides techniques et limiter ainsi les efforts liés à leur utilisation.

Wearable Exoskeletons to Reduce Physical Load at Work
Robotic-like suits which provide powered assist and increase human strength may conjure thoughts of sci-fi and superhero film genres. But these wearable exoskeleton devices are now a reality and the market for their applications in the workplace is projected to increase significantly in the next five years. As with any technologic innovation some of the pros and cons and barriers to adoption are not completely understood. In this blog our objectives are to: (1) describe wearable exoskeletons in the context of workplace safety and health control strategies; (2) highlight current and projected trends...
One Size Does Not Fit All
When your safety and your life depends on it, you need your equipment to fit properly. This is especially true in the workplace. Improper fit may prevent workers from performing their job duties safely and effectively. If your respirator does not seal properly to your face, if your gloves are too big, if your seatbelt cannot buckle with your safety gear on . . . you get the picture. Anthropometry is the science of defining human body dimensions and physical characteristics. The National Institute for Occupational Safety and Health (NIOSH) conducts anthropometric research to prevent work-related...
Gravitational demand on the neck musculature during tablet computer use
Tablet computer use requires substantial head and neck flexion, which is a risk factor for neck pain. The goal of this study was to evaluate the biomechanics of the head–neck system during seated tablet computer use under a variety of conditions. A physiologically relevant variable, gravitational demand (the ratio of gravitational moment due to the weight of the head to maximal muscle moment capacity), was estimated using a musculoskeletal model incorporating subject-specific size and intervertebral postures from radiographs. Gravitational demand in postures adopted during tablet computer...
