Selon les chiffres l’Enquete sur conditions travail, d’emploi et sante securite du recemment publiee, quebecois cinq (20,5%) souffrirait (TMS) lies au travail. Les TMS comptent pour 38% lesions indemnisees par Commission Sante L’intervention ergonomique visant reduction l’exposition aux facteurs risque demeure meilleure strategie prevention cette intervention est subordonnee a l’identification ces risque. La litterature recente en ergonomie propose une variete methodes d’observations ayant ete developpees afin d’estimer TMS. Elles ont objectif supporter prise charge entreprise. Toutefois, offre encore peu recherches appliquees mettant l’epreuve le terrain comparer resultats qu’elles produisent.

According to the recently published Enquete one five Quebeckers suffer from MSDs. MSDs represent all injuries compensated by Quebec’s worker compensation board. Given significant impacts MSDs, industries need work on prevention. The scientific literature shows that reduce exposure MSD risk factors best strategy. Recent ergonomics offers variety observation methods for assessment. Some were developed with intention supporting industry-led efforts and provide important guidelines implementation occupational health safety strategies. Yet, existing showcases little applied research tests field compare results they produce. This doctoral thesis performs analysis obtained assessment based observation, studies relationship between pain perceptions workers regarding their workstations. observation-based are compared homogeneous groups. In workstations evaluated, involving 567 different tasks firms various sectors economy. Data gathered using video measurements taken at A experienced body regions, during months seven days prior data collection, was also administered employees participating study.
