"The Challenges of Musculotendon Forces Estimation in Multiple Muscle Systems"@en . "This study, investigated the practicality, and sensitivity of several different methods of calculating muscle forces during functional activities in humans. Two dynamic systems were chosen, the upper extremity, where the movement flexion/extension elbow joint was characterized and the lower extremity, where the complex squat motion was studied. The redundant mechanisms were solved using optimization criteria with models of individual muscles according to their active and passive properties. Additionally, determination of muscle forces was examined using an artificial neural network and muscle parameters without apparent dependence between inputs muscle parameters and outputs muscle forces. Moreover, if muscle models with active and passive properties are included in these analyses, it is relatively easy to calculate muscle forces of both agonists and antagonists."@en . . . . . .
