Foot model

Hi,
I was trying to make 2-segment model for tibia and foot. When I load
the file, it builds it properly. But when I run SetInitialConditions , then
it completly changes the orientation of all segments. Why is it doing so?

Here is the model I am using…

Hi all. I am following a study on TAR and need to get internal forces
of the ankle joint through ANYBODY. I got kinetics and kinematic data
thought VICON in gait anaylsis and it is time for me to make a foot
model and constraint joints.

As a start, I would like to ask you about the foot model available in
your repository. Is it 1 segment model or multiple segment? Is it
possible to make a multiple segment foot model in ANYBODY? Does anyone
have it?

Now if somebody is expert in GAIT3D or PLUGINGAIT model, do you think
that i might be useful to get internal forces if i already have the
external data ?

thank you

Hi ?

There is no multi segmented foot available at the moment it is a one
segmented model. It is possible to create a multi segmented model, there has
been some work on this issue please see

http://www.anybodytech.com/116.0.html?

&tx_ttnews[tt_news]=21&tx_ttnews[backPid]=37&cHash=a4a430913d

A multi segmented foot model is complicated to construct due to the multiple
interconnected bones in the foot, it is possible, but it will take some
time.

If you have kinetic and kinematics’ data you should have enough information
for defining a gait model. The gait model will give you the internal forces
in the joints and muscle activations patterns. If this is useful for you is
difficult to answer it depends on what you are trying to investigate?

I got a look of the two multi segment models and it looks a promising
starting point.
I need to get internal muscle, tendon and ligament forces around the
ankle joint and this why i thought that a multi segment foot model is
better for my study.
How can i get those two models that were created ?

Hi Mike

The two models mentioned in the newsletter are models created by the users
so I can not help much on providing you these models.

Creating a multisegmented foot model with ligaments and muscles is a big
taks, it will a long time to do, and include litterature studies for date
etc. If you should do this or not? depends on how much time you have for
this project? and what is the goal of your model?

Using the model which is there now, will give you some of the results you
are looking for, but it is clear that a good foot model will give you more
accurate results for the forces in the ankle.

Hi

Currently I am first year PhD student and my task is to go through FE
analysis study of TAR using the internal forces. I need to learn about
Vicon and get data from controls and patients too. i have noticed that
modelling the foot in anybody is a major task and maybe a PhD by
itself. I was looking at one of the models in this newsletter that
interested me. I think that Dr bruce did import? a foot model from
outside anybody and then modelled the ligament there. Currently i have
acess to a CAD foot model. Do you think there is way to export it to
ANYBODY without changing constraints ? and then i can modify it and
work further on it.

How much time do you think we need for modelling the foot and how much
difference will occur in term of approximate percentage between 1
segment and multi segment.

My goal from this model is to get internal forces for i can use them
in FE analysis where i need also to model the TAR …

Hi Mike

I think the model shown in the newsletter has been made bottom up in
AnyBody, only the CAD surfaces has been imported.

You can import CAD files into AnyBody in the form of STL files, this is a
simple format that nearly all CAD system can produce. This will however not
let you import any constraints between the bodies these will have to be
defined inside AnyBody.

So if you have a CAD model running with the correct constraints applied. I
guess it would be possible to replicate these constraints one by one in
AnyBody, but this will be a manual task. Then the next thing is the muscles
and tendons it is a big task.

It is difficult to give a precise answer on how much time you will need to
create a foot model, it depends on lots of issues such as:

1 How many segments will you include?, some segments could be lumped.

2 Kinematics: How should the kinematics of the foot be controlled?, if you
have all segments in the foot you may need to implement kinematic rhythms in
the model, since it will be difficult to work with a model with too many
dofs. By implementing a kinematic rhythm into the model you make assumptions
on how certain dof move wrt. each other, this is effectively what we do in
the spine.

3 Muscles: you may choose to implement moment generating muscles in the
joint instead of the real muscles. This will be a faster approach, if you
can find some information about joint strengths. This approach has the
drawback that it will not provide the real joint reaction forces because it
will be lacking the contribution from the “real” the muscles.

If you will add the real muscles it will be a big job to collect the needed
muscle data, implementing them and control the moment arms.

It is difficult to give you a number on what will be the difference I do not
have much experience in this, it may also depend a lot on the load
conditions.

Without knowing you project in detail, my advice would be to start with the
bodymodel which is there now, get some experience with this one and then
decide if you will need a better foot model.

Please ask again if you have further questions.

Best regards
