Muscle Activation

Kinematic and muscular redundancy in the human musculoskeletal system makes it difficult to evaluate the function of specific muscle groups. The neck is particularly challenging, with seven cervical vertebrae and more than 20 muscle groups. Muscle atrophy of the deep neck extensor muscles has been identified using quantitative Magnetic Resonance imaging in individuals with chronic whiplash disorders. However, the biomechanical consequences of weakness to his muscle group is unknown. In this work, we develop utilize musculoskeletal models, Bayesian inference, and information theory to develop a testing algorithm to efficiently estimate the strength of individual muscle groups of the neck through physical strength testing.
