Try to switch to the min/max criterion.

Greetings,...

If you have the data, the model would be able to handle a dynamic biting force as input.
The challenge is to get the experimental data. It is for example really difficult to measure the distribution...

Hi Michala,

This is what I did. In my model of the human jaw I force the condyles of the TMJ to be in contact with the fossa. In this way I end up with a mandible with 4 DoF.

For driving the...

Mandible model webcast

Hi Michala,

You are right. It is not on the webside anymore. I have attached my presentation here as a pdf file.

Hi Cathy,

(1) These muscles are actually part of the shoulder model, so that's why they are not mentioned in the MuscleCervicalSpineLeft.any, but when you load for example the application...

Hi Cathy,

The neck model is indeed implemented in the version 1.1 of the repository. The example MaxForceNeckModel is an example where the only the neck model has been used in order to find the...

If you want to have the tendon force to be zero that you have to make sure that both the force in the contractile element and the force in the parallel elastic component are zero.
That can be done...

Hi Hauke,

In the 3E muscle model, the force in the tendon is equal with the sum of the force in the active part and the passive part. So if you want the passive force to be zero, then the force in...

Hi,

I also would suggest the following article:
http://dx.doi.org/10.1016/S1050-6411(97)00028-X

It is a more practical view on how to fit your muscle model to measurements.

Cheers, Mark

Hi Jokke,

The width can be controlled by the optimal fiber length. A longer optimal fiber length will give you a wider force-length relation. The position of the optimum length relative to the...

Hi Peter,

I would like to make some more general points on validation with the help of EMG. First thing to realize that validation like this is really tricky business.

Well, both. As far as I remember we have been inspired a lot by the work of Bogduk mostly in relation to the multifidi. There are so many fascicles in the model, so it is important to have a logical...
