AnyBody references

Hello,
I have a question similar to Jean-Olivier’s. I see the recent
references that document the lumbar model (Hansen et al. 2006; de Zee
et al. 2006), and the document that details the knee model (Eshius
2004). Is there a similar reference that documents all of the lower
extremity, including the muscle parameters? Or is the Eshius paper
the one to cite? Or is there one reference for the entire AnyBody
modeling system?

Thank you,
Brent

Brent,

It is a good and very relevant question (and thanks for noticing the
new papers we have out).

The Eshuis reference is probably not a good choice because it is a
master thesis rather than a real peer-reviewed publication. We do not
have a good reference of our own on the lower extremity model because
we originally lifted all the data from Scott Delp’s data set, which is
available from the ISB homepage,
http://isbweb.org/data/delp/index.html.
There have been slight improvements made over time to the model, but
most of them are unfortunately not documented. I would use the Delp
reference if I were you. We have also used data from the publications
of Maganaris to set up the automatic calibration of the tendon lengths.

About the entire AnyBody Modeling System: I am glad to announce that a
real paper is finally coming out. The paper has been in an accepted
state in a journal for several years, but for unknow reasons it did
not get published. The paper is now in the final stages of checking
proofs, and it should come out very soon - we hope.

The reference is:
Michael Damsgaard, John Rasmussen, Søren Tørholm Christensen, Egidijus
Surma, and Mark de Zee (2005): Analysis of musculoskeletal systems in
the AnyBody Modeling System. Simulation Modelling Practice and Theory.
Elsevier, ISSN: 1569-190X.

We have been informed that the reference through Elsevier’s Science
direct system will be:
Michael Damsgaard et al., Analysis of musculoskeletal systems in the
AnyBody Modeling …,
Simulation Modelling Practice and Theory (2006),
doi:10.1016/j.simpat.2006.09.001

John,
Thank you for the list of references; they will be very helpful.

The recent papers on the spine have also been very helpful in
understanding the model!

Hello,
Another question about a reference.

Will the spine rhythm be explained in the to-be published paper on the
entire modeling system?

Does the spine rhythm evenly distribute the rotation among all the
lumbar vertebrae, or is there an algorithm used to unevenly distribute
the rotation?

Hi Brent,

You give me that chance to flash this reference:
http://dx.doi.org/10.1016/j.jbiomech.2006.05.030

Unfortunately it does not say much about the spine rhythm and
neither does the upcoming paper on the system itself. The latter is
only about the system and not about the models.

The best I can offer is a pdf file with some slides explaining how
the model works. It is called spine.pdf, and you will find it in the
files section.

Best regards,
John

Thanks John,
I was reading that reference you provided a link to. The slides
explain that beam theory is used to determine the deflection of the
spine. So that I may understand: Does the matrix in the spine rhythm
algorithm provide the coefficients in the deflection equation?

w(x) = a0 + a1x + a2x^2

So a0, a1, and a2 are coded in the script? Or is there a value for E
and I of the spine?

Then the rotation of each lumbar vertebrae is a function of its
deflection, and the vertebrae is aligned with the slope?

Brent

PS. I suppose I should have started a new thread titled “Spine Rhythm”.
