Anthropometric data

Archive AnyScript Yahoo archive
1

Hello there,

I would like to include bony landmarks in my model. I have a hard time
finding data that can be fitted on the model because I lack certain
important information. Where do the current anthropometric data come from?
Is it all from Vaughan’s book, like the Gait example? Or is it Winter’s
book? White’s article? De Leva (Zatsiorsky-Seluyanov) article?

Mostly, I speak of the joint centers (KneeJoint, HipJoint, AnkleJoint nodes)
and inertial/mass data.

Thanks guys!

Hi again,

Maybe I should clarify my question.

We have the standard definition for the leg segment’s lengths, masses and
densities (see Leg3D\StandardParameters.any).

  •      The density is constant and set to 1000.

  •      The mass corresponds the Winter’s segment mass values (as the

comment suggests…)

  •      But the lengths of the segments do not seem to correspond to

Winter’s data, if the standard model really measures 1.80m (BMI declaration,
see BodyModels\Include\BodyParameters.any)

So here’s the upgraded question: how to you get those segment length?

Please excuse my hesitation; I learn both biomechanics and Anybody at the
same time, so I never know if I’m missing the obvious or If the obvious is
missing… Unfortunately, It always seems to be option A… :wink:

Thanks!

Dear Jean-Olivier,

You have asked a very relevant question. The lower extremity model in
the repository is built using different sources. This also implies that
the dataset used for building the leg model is not really consistent.

The segment masses and the location of the center of mass were estimated
using the estimation reported by Winter (Winter, D. A., 1990,
“Anthropometry,” Biomechanics and Motor Control of Human Movement,
Wiley, pp. 51-69.).

The rest of the model was mostly based on a model built by Scot Delp
(Delp, S. L., Loan, J. P., Hoy, M. G., Zajac, F. E., Topp, E. L., and
Rosen, J. M., 1990, “An interactive graphics-based model of the lower
extremity to study orthopaedic surgical procedures,” IEEE Transactions
on Biomedical Engineering, 37, pp. 757-767.)
Have also a look at: http://isbweb.org/data/delp/Muscle_parameter_table.txt
So most of the muscle data like peak isometric force, optimum fiber
length and pennation angle were bases on Delp’s data. There are though
some exceptions like the soleus and tibialis anterior. The optimum fiber
lengths of these muscles were based on data reported by Maganaris
(Maganaris, C. N., 2001, “Force-length characteristics of in vivo human
skeletal muscle,” Acta Physiologica Scandinavica, 172, pp. 279-285.)

This brings me to my next point. It would be nice that we have a leg
model based on a consistent data set. Very recently there has been a
publication in Clinical Biomechanics by Klein Horsman et al were they
actually report a quite detailed dataset of the lower extremity:
http://dx.doi.org/10.1016/j.clinbiomech.2006.10.003

It would be really nice if someone has the possibility to build a new
lower extremity model based on this new data set.

Hello Mark,

Thanks for this very detailed answer, but this brings a few more questions:

  1. In Delp’s article (fig. 4), the ankle joint axis are rotated around the
    medio-lateral axis (as described in Inman’s article) and on the longitudinal
    axis (by 8 degrees). Looking at the ankle joint (see Jnt.any) and AnkleJoint
    from both the shank and foot (see Seg.any) I conclude that these two
    rotations aren’t present in the model. Am I right?

  2. In a previous post
    (http://tech.groups.yahoo.com/group/anyscript/message/752), I asked if the
    knee model was the one described in the publication section. The answer is
    no, but I notice that we did not discuss the current model. In Delp’s model,
    the knee comes from Yamagushi’s article, and is modeled as an ellipsoid
    epicondyle with a flat plateau, with the contact point as described in
    Nisell’s article. But as I look at the model, am I right to conclude that
    currently, the knee is modeled as a hinge (AnyRevoluteJoint, see Jnt.any)?

  3. While I now know that segment masses and CoM positions are from Winter’s
    book, I still don’t know where do KneeJoint, AnkleJoint and HipJoint nodes’
    positions came from. In Delp’s article, it seems that this data comes from
    the geometrical data, but it isn’t stated specifically and that data is not
    supplied. So where do segments lengths and/or joint centers positions come
    from (specifically, see Leg3D/Seg.Any line 42, 186, 190, 286 and 293)?

  4. I need to agree that it would be nice to have a more consistent model. I
    will be looking at the possibility of using Horsman’s data, since it both
    provides bony landmarks (which I require), inertial data, muscles and
    ligaments insertion and via points and joint centers. But this is a
    substantial project and is not necessarily in the scope of my master.

Thanks!
Jean-Olivier

In the lower extremity the origin of each segment is the center of mass.
I guess if we would start a whole new model of the lower extremity we
would do it a little bit differently. Anyway let’s take the next part as
an example:

AnyRefNode AnkleJoint = {sRel = .Scale({0.0, -0.2608, …Sign0.0});
#include “…/DrawSettings/JointAxesDistal.any”
};
AnyRefNode KneeJoint = {
sRel = .Scale({0.0, 0.1992, …Sign0.0});
#include “…/DrawSettings/JointAxesProximal.any”
};

It is here where we define the joint locations of the ankle and knee
joint in the segment shank relative to its center of mass. In this way
we basically define the length of the segment as well being
0.2608+0.1992 = 0.46 m
According Winter the center of mass is located 0.433*(Segment length)
relative to the femoral condyle. Indeed 0.433*0.46 = 0.1992.

So the question is where does the length of 0.46 m comes from? You are
right, that it is not stated specifically in Delp’s paper, so actually I
used the length of my own shank as reference, which is a little bit
larger than average. The data we used from Delp was mostly the muscle
parameter data.

It is indeed quite some work, but I actually think that it would fit
quite well for a master project.
Are there any potential students out there, who could be interested in
doing this?

Hello Mark,

This answers all of my questions quite well. Thanks a lot.

As of the lower body model, my director seemed interested. I forwarded our
discussion and the article to him. I do not believe he has any student
available for this project right now, but this can change quickly… We’ll
see what happens.

Thanks,

Jean-Olivier

Good day Mark,

I have a few more questions for you if you don’t mind.

  1. In the repository, in the toolbox section, the Kit Vaughan set of
    markers is available. Would it be possible to know the transformations that
    were used to transform those data into the model values? I am not sure how
    you combined Vaughan’s markers with Winter’s BSP data. I also would like to
    include the missing Vaughan marker (5th metatarsal) into the model, but
    would like to use a consistent method.
  2. Again, in the repository, not all markers from the kit Vaughan set
    seem to come from Vaughan’s book. The metatarsal landmark is of the 4th
    metatarsal head (if I’m correct) while Vaughan only supplies the 5th
    metatarsal base. Where does that datum come from?

I really appreciate your help,

Jean-Olivier

Hello Jean-Olivier,

Mark went on paternity leave on March 1, so he may not be able to
answer for a while. I am not sure whether he follows the group from
home, but my guess is that he has his hands full :wink:

Hi John,

I’m absolutely sure he’s got his hands full and I wish him great times!
Congratulations to him!

Actually, I hope he won’t be looking at his e-mails from home so he can
fully enjoy the moment.

On the other hand, I would need to know how long a Dansk paternity leave is.
:wink: In any case, my other post might give me the answer I need anyway, we’ll
see.

Thanks,

Jean-Olivier

Hello Jean-Olivier,

Mark went on paternity leave on March 1, so he may not be able to
answer for a while. I am not sure whether he follows the group from
home, but my guess is that he has his hands full :wink:

Best regards,
John
