Hi everyone, I am trying to analyze the effects of a passive ankle and want to use the muscle analysis and probe reporter routine of Opensim. I have data from an able-bodied subject. Now if I replace the ankle angle in the kinematics file with all zeros and keep everything else (all other joint angl...

Dear Thomas,

Thank you very much for the suggestions. I will try them.

Thanks and Regards

Dear Thomas, Thank you for the answers. For the answers to questions 1 and 2, I will follow as you suggested. Just one follow-up with adding the feed-forward controller: how do I specify that the control points correspond to the values of the ankle -joint torque pattern in the sagittal plane? For qu...

Dear Thomas, Thank you very much for the answers. I have three follow-up questions. 1. Just to confirm, to ensure, that the provided torque pattern be automatically in phase with the gait cycle, I need to set the initial states in sync with the start of the gait cycle corresponding to my torque patt...

Hello everyone, I would like to do a forward dynamic simulation and finally get the torso angle and angular velocities to construct a phase portrait for assessing gait stability. However, I would like to do it given some pre-computed ankle-torque. Basically, my aim is to asses how the stability of g...

Hello Thomas,

Thank you very much for your reply. I just have one extended question. Is there a way to get the muscle activations from the joint moments in SCONE?

Thanks and Regards

Hello Thomas, Thank you very much for the quick response. I use a machine learning model for predicting the joint moments. If it is possible to integrate this model with SCONE, this would be great. If not, I would also be happy to know how I could "input" my predicted moments into the SCONE, so that...

Hello everyone, I am new to biomechanics and multibody simulations. I have a predictive model that generates joint moment trajectories. I would like to validate how these predicted trajectories effect the metabolic cost. While searching possible ways to do so, I came across SCONE. I would like to se...

Dear All,

I would like to do something similar (closed-loop online control using a custom control). Could you please guide me as to where I can find the controllerexample currently?

Thanks and Regards

Dear all, Could anyone point me to how the COM positions are calculated by the body kinematics routine of Opensim? Does it require only the masses of individual body segments and the joint kinematics? i.e., to compute the COM positions (through body kinematics analysis), it is sufficient to use only...
