Effects of bi-articular muscles
Hello, I have a question concerning the Static Optimization (SO) workflow in OpenSim and its treatment of bi-articular muscles. I understand that the static optimization process calculates the joint moments at each time point based on the input motion data, then uses an optimization algorithm to dis...

Re: Muscle Forces for Pre-Defined Final Pose
I got your point.
So, unlocking all the coordinate is more of a practical where the muscles crosses more than one joint.
Thank You

Re: Muscle Forces for Pre-Defined Final Pose
Hi Thomas, Thank you very much for the reply and pointing me to the tutorials. I have already gone through those tutorials but don't know why I am still struggling with it. I have used MoBL-ARMS Upper Extremity Dynamics Model, I have locked the coordinates as shown in Figure below to generate a FD f...

Re: Muscle Forces for Pre-Defined Final Pose
- unlock the arm coordinates - estimate muscle forces using the Static Optimization or CMC Tool If I am interest only in the elbow flexion, can I just unlock the elbow_flexion coordinate from "MoBL_ARM_Dynamics_Model". I tried with only elbow_flexion coordiante ON and with all other coordiantes on ...

Muscle forces in upper extremity model
Hi, I am looking to estimate the muscle force for the elbow flexion (from 0 to 90 degree) with the muscle force generation capacity of 50th percentile man. I have used the Upper Extremity Dynamic Model (latest one). I have gone through the tutorial and made a similar motion file that includes all th...

Static Optimization
Hello,
I was wondering whether this model is suitable for SO or CMC ?
I want to use to calcualte the muscle force for some defined pose only not for the motion.
Thank You

Re: Muscle Forces for Pre-Defined Final Pose
Thank you very much for the reply. It will be the beginning point for me. I have been going through all the papers published for shoulder models. So, combination of both should work.

Muscle Forces for Pre-Defined Final Pose
Hi, I am just a begineer to the OpenSim, I was wondering if we can use the Musculoskeletal Model avaiblae in the OpenSim to obtain the muscle forces for fixed pose. For an example, if I rotate my Glenohumeral (GH) Joint to 90 degree internally and have 30 degree elbow flexion followed by 20 degree G...

Obtaining muscle and joint forces for static poses
Hi, I am currently working on Cross Body Abduction (CBA) and Hand Behind the Back (HBB) Test. I have a set of rotation associated with Glenohumeral, Wrist and Elbow joint that will lead me to the final pose for CBA and HBB from anatomical position of the shoulder complex. I want to calculate the mus...
