Comparative analysis of manual handling practices in kerbside collection of recyclable waste
Government targets for reducing waste going to landfill h ave led to an increase in the processing of domestic waste to reclaim recyclable materials. Manual sorting tasks can occur at the kerbside during waste collection and, if poorly designed, can introduce manual handling risks. This report describes research to better understand the kerbside collection and sorting methods currently employed by the waste industry and to determine how manual handling risks can best be reduced or controlled. Six detailed case studies are presented showing a range of vehicles and processes in operation. Manual...
Troubles musculosquelettiques et santé psychologique
Démarche de soutien aux activités de prise et de répartition des appels d'urgence 9-1-1 La présente étude constitue un prolongement des recherches antérieures ayant pour objectif de réduire les risques psychosociaux associés aux troubles musculosquelettiques et de santé psychologique chez les préposés des centres d'urgence 9-1-1. Elle se fonde plus précisément sur la précédente recherche (Toulouse et coll., 2011) dont les résultats suggéraient la nécessité...
A structural equation modelling method to describe work environment risk factors and musculoskeletal symptoms among hospital nurses
OBJECTIVES: Epidemiological studies have shown that musculoskeletal symptoms are frequent occupational injury and disability among nurses in developing countries. Preventive measures were not able to reduce musculoskeletal disorders significantly in nursing profession. This study was performed to provide a comprehensive assessment of the association among risk factors in developing musculoskeletal symptoms. METHOD: A structural equation model was applied to describe and analyse complex causal relationships from sets of occupational variables involved in musculoskeletal symptoms. A questionnaire...
Vibration and mechanical shock exposure strongly associated with prevalence of neck pain
The objective of this study was to determine whether whole-body vibration (WBV) and mechanical shock exposure from quad bike use are associated with the prevalence of neck and low back pain (LBP) in New Zealand farmers and rural workers. Physical exposures (mechanical shocks), employee status, and low levels of workplace satisfaction are all significantly associated with the 12-month prevalence of LBP in this rural workforce that regularly uses quad bikes. Both vibration and mechanical shock exposure were strongly associated with 12-month prevalence of neck pain. The 7-day prevalence of neck pain...
Étude pour intervenir sur la réduction des troubles musculo-squelettiques et de santé psychologique dans les centres d’appels d’urgence 911 de la sécurité publique municipale
Une recherche multidisciplinaire a permis de mieux cerner les dimensions de la charge mentale en lien avec les TMS et les problèmes de santé psychologique des préposés des centres d’appels d’urgence 9-1-1, profession qui a été jusqu’à maintenant peu étudiée par les chercheurs. L’étude démontre que leur travail est loin d’être celui « d’un simple répartiteur d’appels » puisqu’ils doivent faire face avec efficacité à la gestion du flux...
Ergonomics at materials recycling facilities
Conveyor belts are used in several industries to move materials. Using these systems in the workplace can reduce the risks of Musculoskeletal injury (MSD) by avoiding the need for excessive repetitive lifting and carrying. However, conveyor belt workstations should be properly designed to ensure that operators do not excessively lean, stoop, twist, or over-reach, since these repetitive movements can themselves lead to musculoskeletal injury. The workplace, size of the conveyor, type, through put and height of material, and how material is handled, are all factors to consider when assessing the...
An investigation into the use of plasterboard manual handling aids in construction
The purpose of this report is to investigate the manual handling and work related risk factors for MSD associated with the installation of plasterboard, and to evaluate the impact of manual handling aids in terms of risk reduction and the time taken to install plasterboard.

La revue PISTES consacre son dernier numéro aux TMS
Dans la foulée d'une première conférence organisée à Nancy en 2005, se tenait à Montréal, en juin 2008, la 2 e conférence du Groupe de recherche francophone sur les troubles musculo-squelettiques (TMS). Organisée par l'IRSST et parrainée par la Société d'ergonomie de langue française (SELF) et l'Association canadienne d'ergonomie (ACE), cette conférence, De la recherche à l'action, réunissait plus de 250 participants : chercheurs, praticiens et acteurs des milieux...
