Hi everyone,

I am looking for a musculo-skeletal model, with the whole body model included, to do a forward dynamics.
I searched the model library and found a model from https://simtk.org/home/ulb_project.
It provides a useful starting model to those interested in a full body model. Howerver, there are no muscles around the neck joint, which was neglected. Also, The data of mass, center of mass and inertia moment of the upper-extremity is not available in that model.
So Is there any whole body OpenSim Model (.osim) , including the model of lower extremity, upper extremity and neck, available to download? If it is not available, any idea for constructing such a kind of model?

Best regards,

Jiang

There isn't a model like this that I know of. You might be able to combine a neck model with another full body model.

I'm curious about how you plan to use the model. What structures or motions are you most interested in and what questions about those structures or motions do you hope to answer? For example, taking the Upper Lower Body model and adding the structures from one of the neck models in the library might give you some trouble with using CMC or Static Optimization. If you plan to use these tools to estimate muscle forces during some motion, I'd suggest using a simpler model that has more detail in the particular muscles, joints, etc. that you're most interested in.

When choosing a model you also need to carefully examine what the model was intended to do and how it's been validated. For example, some models in the model library are intended for kinematic analysis (e.g. to look at joint angles or muscle-tendon lengths) rather than full dynamic simulations. Please take a look at this document for some more information on selecting and evaluating a model:
