D’une analyse ergonomique en situation réelle de travail à la mise en place d’un programme d’activités physiques adaptées pour la prévention des troubles musculo-squelettiques de la région lombaire de salariés viticoles

Work related musculoskeletal disorders (WMSDs) affecting the low back are conditions highly prevalent in viticulture. Their multifactorial origin makes their prevention difficult and still challenging. The first objective of this PhD thesis was to conduct a field ergonomic work exposure analysis investigating the location and severity of WMSD symptoms and measuring the kinematics during pruning activity. The second objective took its assets in the above mentioned analyses and consisted in the conception, implementation and evaluation of a workplace supervised adapted physical activity (APA) program for the prevention of WMSD of the low back among vineyard-workers. As a whole, this PhD thesis demonstrated that, based on a field ergonomic work exposure analysis, a supervised workplace APA program can be considered a promising solution to prevent WMSDs and can be integrated as one component of wine-producing companies’ health policies already including ergonomic approaches.
