Évaluation des efforts dans la colonne vertébrale et risques de blessures de tissus au cours des tâches industrielles d'élévation de charges : rôle de la posture

Résumé

Le soulèvement de charges a été associé aux troubles musculo-squelettiques du bas du dos, mais la question des bonnes postures à adopter est loin d'être résolue. L'auteur propose un modèle d'analyse des charges sur la colonne vertébrale occasionnés par les tâches en postures neutre ou fléchie, avec ou sans poids supplémentaire. L'évaluation des efforts subis par la colonne au cours des tâches de manutention permettra de déterminer plusieurs facteurs primordiaux tels les niveaux admissibles et la limite plus sécuritaire des charges pouvant être supportées par les travailleurs, ainsi que les postures optimales pour la réduction des risques de blessures et de maux de dos. Cette recherche contribue à évaluer la distribution des charges entre les éléments passifs et actifs ainsi qu'au niveau des tissus biologiques. Les données ainsi recueillies pourraient permettre par la suite d'évaluer des performances physiques, d'optimiser les exercices de réadaptation de même que les opérations thérapeutiques.
