Muscle parameters

The aim of this project is to provide validated musculoskeletal full-body models including a detailed thoracolumbar spine for boys and girls aged 6-18 years.

Muscle parameters

Post by karlijn Spijker » Mon Apr 08, 2024 7:28 am

Hello,

I am quite new to open sim and I am using the models for my graduation project.
I have a question about the muscle parameters in the different models and I hope you can help me to get some thing clear.

I understand the Isometric force of the different muscle are determined using the cross sectional area measurement for the available muscle. if not available, this parameters is scaled.

However, I see the optimal fiber force and tendon slack length are also changes for different ages. Are these value changed after scaling for height and weight?

Another question I have is how the values of the calculated CSA are actually put in the model? I see for example QL consist of many bundels.

I hope you can help me with this.
