Ankle ligament model existing

I am attempting to quantify ankle ligament strain during different movements for one of my experiments. I was wondering if anyone knows of an existing model available to download that I can contrast my results against.

KL model

Hi everyone I'm currently attempting to use the new knee ligmaent model in Opensim. I'm having trouble getting the RRA/ CMC to run using this model. I've used the standard gait models in opensim to perform inverse kinematics previously for some time without any issues. Does anyone familiar with usin...

Model with Knee Ligaments

I am wanting to use the new Osim model with knee ligements to quantify ligament kinetics in dynamic tasks. I currently use Visual 3D and export to Osim, however the Visual 3D export is coded to correspons to the gait 2392 model and thus constrains the knee to 1 degree of freedom which is not consist...

Re: Model with Knee Ligaments Public Forum

Hi I am trying to use the model with knee ligaments to calculate ACL forces during dynamic tasks. I export my dynamic data from C-motion software (Visual 3D). This works fine for the traditional Gait2392 models, but I am having problems when using the new knee model. The model seems to scale ok usin...

RRA issue

Hi all I am trying to use opensim 3.2 to simulate muscles forces during running CMC.computeControls: ERROR- Optimizer could not find a solution. Unable to find a feasible solution at time = Model cannot generate the forces necessary to achieve the target acceleration. Possible issues: 1. not all mod...
