Hi,
I'm after a full body model that has a more detailed description of the lumbar spine as I want to estimate joint loadings in this region during Sit-to-Stand. From what I've been told, most of the full body models approximate the lumbar joint as a simple ball and socket. I've seen the Lumbar spine model which looks promising but I would need arms, legs and head. I'm new to OpenSim so I'm unsure about what is and what isn't possible but is there a way to ‘replace’ the torso section of an available full body model with the Lumbar Spine Model? Any advice would be greatly appreciated,
Sam
