Default Ligaments and Passive Elements

Hello,

In the webcast titled "Computing realistic loads in the lumbar spine by using the AnyBody musculoskeletal model" that the standing human model does not have ligaments. My question is, is there a way of activating the ligaments in the standard model or any other model in the AMMR? if yes, how does one go about this? The last question is on the passive elements in the muscle model: how does one change the model from, say, the default setting to AnyMuscleModel3E in the standing human model for a particular muscle?
Thank you.

Hi

The standard model does not come by default equipped with all ligaments, they are availble for the spine using the argument (See e.g. SpineFixationWithForceDependentkinematics...)

#define BM_TRUNK_LUMBAR_LIGAMENTS ON

In other models the ligaments has been defined in the model/application such as the Beta/TKA-kneebendmodel (knee ligaments).


To change the paramters for a certain muslce you can do two things.


1: make the change in the MusPar.any in the body part in question, here all the paramters are listed. For the legTLEM model you will need to go into the folder TLEM1.1 and look in the muscleparamters.any file. Note that any changes you make will impact any model you load!

2: if you do not want to edit the bodymodel you can use the SetValue from the ModelTree to alter values of certain parameters.


Best regards
Søren

Thank you, Soren. I have been able to change the MusPar.any but I can't seem to find the Set value item in the model tree. Which folder is it located in?

Best Regards,
Victor

Hi Victor,

The SetValue is not an object in the tree, it is an operation which becomes available through a right click the object you would like to change.

Best regards
Søren
