I am planning to assess the joint movements and muscle response in the hand.
I am currently working with the freeposturemove model.
When i try to create a wrist flexion of 90 degrees, i can see that some of the muscles that are responsible for finger flexion are actively involved during this process. I can see these finger flexion muscle exhibiting some activity and change in power and length.
I know this is true in reality. When we flex our wrist, our finger also flexes involuntarily. But, i want to know if the same applies in the simulation as well because there are no drivers for fingers in the simulation to create that finger flexion.
Could you clarify if creating wrist flexion of 90 degrees in turn causes a finger flexion to happen automatically?
If so, is it possible to have a pure wrist flexion without having the finger flex?
Please let me know.
