"In the presented paper, we discussed advantages and disadvantages of a musculoskeletal open-source software OpenSim for the analysis of the masticatory system. Our simulation is based on a clenching task and open/close movement of the mandible. OpenSim software is a tool for the musculoskeletal system analysis, which provides the users with powerful kinematical analytical tools to analyse the kinematics, the change of muscles and tendons length over time, muscle arms, etc. However, main drawback of OpenSim is the handling of closed loops, which was also our case when the mandible is attached by two temporomandibular joints to the temporal bones. This topic was discussed mong OpenSim users, and the concluding idea was that one should write his own equations of motion rather than use OpenSim\u2019s dynamics engine. In the end, OpenSim\u2019s results are promising. However, the model is highly sensitive to the muscle attachment points and the muscle hysiological properties. Moreover, results from the inverse dynamics are not directly the joint forces, but the net forces and torques, which means the sum of all forces and torques acting on the joint. To validate the presented model, EMG recording should be done synchronized with the recording of the mandible kinematics."@en . . . "2"^^ . "Is OpenSim suitable for masticatory system analysis?"@en .
