| Abstract: | A determinate scheme for modeling the mechanical effects of muscle contractions in a musculoskeletal system, using the direct-stiffness method of structural analysis, is described. Data concerning skeletal geometries, connective tissue passive mechanical properties, and muscle lines-of-action and cross-sectional areas are incorporated to make the model specific for studies of muscle actions in the human trunk. Several illustrative examples of model trunk responses to muscle contractions are presented and discussed. |
