MCoMP computes muscle activations that optimally brace for impact. MCoMP also allows for comparison of different objective functions that intentionally result in coactivation of muscles.

Determining muscle activations required to "brace for impacts" requires optimization techniques that employ objective functions other than what are commonly used in OpenSim (such as in So and CMC). Here we present a tool (MCoMP) in the form of MATLAB script that allows for comparison of different objective functions that intentionally result in coactivation of muscles. MCoMP accepts as inputs an OpenSim model, joints to be stiffened through coactivation, and loading parameters of a force to be resisted. MCoMP outputs forward simulations that utilize muscle activations obtained through objective functions from previous literature and an objective function that we developed. This builds on our previous work (Mortensen, J., et al., 2018. Exploring novel objective functions for simulating muscle coactivation in the neck. Journal of Biomechanics), and will be made available here, pending approval of a manuscript currently in development.
