Dear Stanev,

Yes , I believe you are correct, it is irrelevant. Thank you so much for your reply.

Thanks again,

Hi, I have a doubt regarding the use of ClutchedPathSpring. In this I noted that, both the optimal force and the stiffness values need to be given, unlike in path actuator where only optimal force and in other passive springs, in which stiffness is only needed. The tension produced in ClutchedPathSp...

Hi, I am trying to model an orthosis, attached to the upper limb. This othosis provides compensatory torque to support say a shoulder elevation movement.I am not sure how to add these torque values to the simulation. I have a list of torque values and the corresponding elevation angle values from th...

Thank you for your reply. Yes, I am trying to verify the elbow flexion extension muscles (major muscles). As there was some issues running the static optimization with the schutte muscle model with my original marker data, so I tried to update the muscle model to thelen and for verifying if the mode...

Thank you James for the reply. So it means that if I lock some the coordinates but enough to create flexion I should be able to produce results where biceps is more active and triceps with lesser activity.

thanks.

Hi, I am performing S.O on the mobl model after updating the muscles to Thelen2003 and adding reserve forces. I can successfully run static optimization on a simple model having 4 muscles 2 deltoids and triceps and biceps long for an elbow flexion motion. But when verifying the force and muscle acti...

Thank you for your help. I solved my issue. Just have a small doubt regarding the reserve actuator force. I tried to add a reserve force of 1 N in one simulation and 50 N in another simulation for the coordinates and measured the forces produced by the biceps. Noted that in 1N- the biceps peak force...

Thank you for your kind reply.

Unfortunately both the models have the same number of muscles (reduced the number of muscles of MOBL model). Will check again , why the force is not building up. Thanks again.

Hi, I am trying to perform static optimization on the MOBl_upper extremity model for the elbow flexion motion. I am using and comparing the results with respect to arm26 sample. I am using the marker data for elbow flexion from arm26 and using it on the mobl model. In the mobl model- I fixed the tra...

Hi, I am trying to perform static optimization on the upper extremity model by applying a constant reaction force ( measured from a hand held dynamometer) near to the wrist region. The goal is to find the muscle forces generated during an isometric test for elbow flexion. My doubt is since the joint...
