About adding extra hip joint moments

[Paul Chris]

Hello,
Regarding the addition of an external driving torque to the revolute joint of the booster device alone, the muscle force of the main flexion and extension muscles at the hip joint of the human musculoskeletal model is reduced and the overall lower limb metabolic consumption is reduced. I tried to add GeneralizedForce to the revolute joint. But it failed to achieve the expected effect. Is there any relevant OpenSim tool to achieve this goal or to help me with some suggestions? Thank you very much. The specific problem I want to solve is to assist the movement of the lower limbs of the human body through external devices, so as to achieve the goal of reducing the consumption of the lower limbs of the human body.

thank you for your reply

Chris
