Numerical validation of a subject-specific parameter identification approach of a quadriceps femoris EMG-driven model

The estimation of individual muscle forces exerted during a motor task is a challenging problem in biomechanics, however with many potential applications [1,2]. For example, the assessment of imbalances in muscle synergies can be used to improve athletic performance and suggest rehabilitation strategies for neural or orthopedic patients. Mathematical muscle models can be used for this purpose since force measurements cannot be directly obtained in a non-invasive way. Muscle models are frequently part of a larger musculoskeletal dynamic model, which is analyzed through a forward or inverse dynamics formulation [3,4].
