Abstract

Musculoskeletal modelling of the spine is the only non-invasive approach to enable estimation of loads on the internal structures of the spine. The research team aims to combine and adjust the complementary characteristics of three different previously developed musculoskeletal models in order to build a hybrid model. The new model will provide solutions that are better adapted to individual movement and activation strategies of the torso muscles. The hybrid model will make it possible to better estimate a number of parameters for various groups of worker clients, such as the margin of lumbar stability.

The margin of lumbar stability is an indicator, potentially associated with low back pain, that will be added to other measurements of workplace exposure. This indicator will also make it possible to validate handling techniques or prevention training programs, as well as the effectiveness of rehabilitation programs.
