Estimation of Lumbar Loading through Articular Biomechanical Models: Applications and Developments


Loading on the lumbar spine is an important risk factor for back pain, especially when the loads are too heavy or too light. Biomechanical modelling of the spine is the only non-invasive approach for estimating this loading. There are several types of models, such as that using electromyography and another using kinetics, for measuring loads on the lumbar spine of individuals in work situations, such as materials handling.

This project aims to improve fundamental aspects of the models and apply them in concrete work situations, with a view to helping researchers and ergonomists estimate back loading.
