Hi everyone,

Is there any detailed OpenSim model available for the hand? I need the model to assess loads applied to the scaphoid bone during multiple activities of daily living. I appreciate any information that helps.

With kind regards,

Dear James,

Thanks for your clear reply. I implemented your advice in the model and now it is working well. About your suggestion on uploading images that show the problem, you are right and I will do it in future.

Dear Ross,

Thanks for introducing the articles. I got a very good insight to the problem by reading them.

Dear All, I am trying to include surface to surface contact at tibiofemoral joint and knee ligaments into the Rajagopal Opensim model as I thought it could improve joint reaction force predictions of the model. I have skin marker data, fluoroscopic_based kinematics, EMG and ground reaction forces. I...

Thanks a lot James. I tried the same for a ligament, and it works.

Dear all, I am trying to change insertion point of a ligament and see the effect on ligament load. As I have to do this for 100 runs, I am trying to do this as batch process in matlab. The problem is that, I do not want to create 100 models, save them with different names and then run IK for them. I...

Hello everybody, I want to develop a subject specific musculoskeletal model of a TKA subject based on lowerlimb2010 model. I have coordinates of some bony landmarks on femur (femural head center, medial epicondyle and lateral epicondyle) and some others on the tibia (medial and lateral malleolies) i...
