Modeling of trunk muscle recruitment during isometric exertion.
Prior modeling approaches are reviewed, and a general nonlinear optimization model for trunk muscle recruitment is developed. The effects of the different cost functions and the load vector characterization on the predicted muscle tensions are investigated. Some of the model's limitations are discussed, and some results obtained using six different cost functions are presented and evaluated.
