\TODO{Conclusion about work done}
Musculoskeletal modeling has been instrumental in understanding joint torque and muscle function
during movements based on the physics of the musculoskeletal system. Because generating de novo
muscle-actuated simulations of movement based on performance criteria is challenging as a result
of both muscle redundancy and the stiffness of the solution space, particularly for unstable tasks
such as walking \cite{Ting2012}
Thus OpenSim with the provided and used muscle-skeleton models is in its current state
not feasible for the simulation of tasks such as those that were subject of this project.
\begin{itemize}
\item Precise EMG data from an actual subject (no averaged an processed patterns) would be needed in order to achieve realistic behavior in simulation with OpenSim.
\item Focus of OpenSim more on clinical applications where such data is available.
\item A more abstract musculoskeletal model of a human would need to be developed in OpenSim, for such simulations, but is outside of the focus of this project. The OpenSim API would provide a decent foundation for developing such a model from scratch.
\item Ground contact forces would need to be incorporated (and provided by the study the project is based on).
\item Muscles were removed from the model ``arbitrarily'' (because no data is available for them), consequences for behavior of model unclear
\end{itemize}
More abstract models such as the ones used by Geyer and Herr \cite{Geyer2010}, Marques et al. \cite{Marques2012a, Marques2012} or Wang et al. \cite{Wang2012} might be more suitable.
