Human ergonomic simulation? options?

has anyone done any work using grasshopper for studying ergonomics?

I was wondering if anyone knew of any possibilities to simulate a human form interacting with an object, (Physical ergonomics).  Particularly, the idea of using grasshopper/kangaroo to possibly develop some "sketch" level ergonomic studies.  I understand that ergonomics is not a simple concept, but I am curious if anyone has explored this before.

I just started thinking about the idea but any input or points in the right direction would be greatly appreciated!
