Misalignment of robot joint and human joint


Hi, My name is Alan.
I just started learning to use AnyBody software.
I currently have an elbow exoskeleton (1-DoF) model for elbow flexion/extension. I create a human model with trunk and right arm. The pelvis is fixed. Also, the other joint of right arm is fixed. Only fe joint is free to rotation. I want to obtain the force of the elbow joint when the human elbow joints and robot joint are misalignments. I mean the rotation axis of both robot-human joints are misalignment (maybe 2 or 3 mm). Is it possible to simulate this situation? Could you please help me how to do it step by step? Or is it possible to apply a torque on the point near the elbow joint about 2mm?

Thank you very much.
