- Abstract
- In-vivo measurements are required to validate models and methods of computing muscle forces and joint efforts. Our objective was to confront our hybrid approach, i.e. an EMG-driven model, developed for static configurations to a dynamic case. Our approach relies on making the most of electromyography (EMG) as input of a musculoskeletal model of the trunk to compute muscle forces and resulting intervertebral efforts in the lumbar spine. This study highlighted the potential of using a hybrid approach developed for static configurations to dynamic cases. Intervertebral efforts, especially compressive forces, were similar with in-vivo measurements from an open-access database. Furthermore, compressive forces computed with our method matched the linear regressions reported in the literature. Future work will focus on considering the muscle dynamics for a more detailed comparison.
