Mechanical simulations of the musculoskeletal system are a topic of fundamental importance because they provide information not immediately identified from a kinematic- dynamic analysis of gait or muscle static test, to be relevant for treatment of patients with motor disorders. The causes and appropriate corrective treatment of gait abnormalities are difficult to determine because the movements generated by the muscular forces of these patients are not clearly understood. Mathematical optimization methods are used to estimate individual forces in the human body because direct measurements are difficult to make. The assumption that the central nervous system tries to minimize the load on the muscles in general leads to the hypothesis that muscle strength can be found as the solution to optimization problem. In this paper a mechanical system with six degrees of freedom to model the musculoskeletal system of the thigh that allows the estimation of six individual muscle forces in gait showing high correlation with other models and muscle activation in healthy subjects. These estimates of individual muscle forces would facilitate greater understanding of gait pathology helping to reach better diagnosis prior to surgery and rehabilitation treatments.
