Dear anyscript subscribers,

Hi,
I’m Yoshinori Konishi, a doctorate student at Kyoto University.
I major in biomechanics of human movement and
make a study of the behaviour of the muscle-tendon complex during
movements (especially in jumping movement) using Hill-type muscle model.
I want to study more about the human musculoskeletal modeling by being a member
of this group and using AnyBody software.
To begin with, I have to learn AnyScript language.

Best regards,

Yoshinori Konishi

Dear Yoshinori,

Welcome to the group! For modeling of jumping you should be able to
make good use of the lower extremity model provided in the AnyScript
model repository,
http://anybody.auc.dk/Software/Repository/repository.htm

Do you know the movement already, and if you do, how is it
prescribed? We would be happy to help you with tips on how make the
model jump.

Feel free to ask questions here if you need help.

Best regards,
John,
AnyBody Support.

Hi All,

My name is Oskar, Im currently working in a motion analysis lab in
point pleasant, NJ. We have been doing kinematic studies on a variety
of topics. I was recently introduced to the anybody research group and
i think all the work is fascinating. I am learning the software right
now, but in the future i would love to incorporate our motion data
with the muscle modeling to get a better understanding of the
biomecanics of different movements. I was intereseted in the different
liscences available, and what qualifications i would need to obtain
them. I currently am running a demo liscence.

thanks in advance,
Oskar Kizhner

Hello Oskar, and welcome to the group. Please feel free to ask
questions here whenever you want.

License prices and conditions: I understand that you are in academia.
The software comes in two discounted versions for research and
education:

A research license is 5400 Euro = USD 6500. Research licenses are
sold to univrsities and other research institutions who publish their
work. A research license may not be used for commercial work and not
for clinical work unless is is in connection with research for
publication.

A student license costs 1350 Euro = 1630 USD. Student licenses are
for educational purposes only.

We also offer an educational bundle: If you buy one research license
and one student license, then you are entitled to 20 student
licenses. The idea behind this option is to allow a university
educator to use the software for research and for organized classroom
teaching. This option comes wih the small catch that you have to pay
for the cost price of the hardware dongles for the additional 19
student licenses you are getting “for free”. Each dongle is 100 Euro.

Please notice that these prices can change without notice.

The licenses are perpetual; unlike most other types of technical
software you do not need to pay regular license fees. Minor updates
are free. Major updates are 30% of the new license price. Major
updates can be expected roughly once per year, and we naturally do
recommend people to keep the software updated.

Best regards
AnyBody Support

Hi anyscript-group,
My Name is Peter Westerhoff and I am working on a project developing an
instrumented Shoulder Prothesis to measure the forces and Moments in
the glenohumeral joint at the Biomechanics Lab of the Charite Berlin
Campus Benjamin Franklin. More Information about the project and
impressions of the first measurements can be seen at www.biomechanik.de
In this context I have my first question about one of the Application
in the repository. Is it right that the
variable “Main.Study.Output.Model.HumanModel.Right.ShoulderArm.Jnt.GHLin
Con.Reaction.F” specifies the Glenohumeral contact Force? I was
wondering about the Graph with a high force in X-Direction and almost
no Force in z and y Direction. Is it right that the X Direction (red)
points forward in this joint coordinate system like described in the
ISB Recommendation?
So far by now, thanks in advance
Peter

Hi Peter

Welcome to the group

The coordinate system for the segments in the shoulder follows the
ISB proposal from Frans C.T. van der Helm please see

http://www.fbw.vu.nl/research/Lijn_A4/shoulder/isg/proposal/protocol.
html

for the details

It is correct that the
variable “Main.Study.Output.Model.HumanModel.Right.ShoulderArm.Jnt.GH
LinCon.Reaction.F”
is the GH reaction force

By default the reaction are measured in the scapula coordinate
system but you may easily change this to the humerus coordinate
system if you want. This you can do in the following
file “BRep/Aalborg/Arm3D/Jnt.any”, please find the line
“AnyKinLinear GHLin =…”

You may then replace it by these lines

AnyKinLinear GHLin = {
AnyRefNode &scapula_gh = …Seg.Scapula.gh;
AnyRefNode &humerus_gh = …Seg.Humerus.gh;

//Add a blue coordinate system at the scapula gh node
scapula_gh={AnyDrawRefFrame drw={RGB={0,0,1};};};

//Add a red coordinate system at the scapula gh node
humerus_gh={AnyDrawRefFrame drw={RGB={1,0,0};};};

Ref=1; //use this for shifting between the two ref systems:
scapula=0, humerus=1
};

This will add a blue coordinate system in the scapula gh node and a
red coordinate system in the humerus gh node. The “Ref” object can
be used for shifting which of the two coordinate system should be
used as the reference system.

If you want to measure in neither the scapula nor humerus coordinate
system this is also possible. This can be done by defining a new
node with another orientation and use the AnyForceMomentMeasure
command which can be used for measuring forces and moments in any
coordinate system. Please see the AnyBody reference manual for the
details http://www.anybodytech.com/fileadmin/doc/AnyBodyRefManual.pdf

I hope this answered your questions, otherwise please do not
hesitate to ask again.

Best regards

Thanks a lot for the fast reply,
I think I found the error in the direction of the contact force. I
thought the coordinate System was oriented as described in the article
“ISB recommendation on definitions of joint coordinate systems of
various joints for the reporting of human joint motion —Part II:
shoulder,elbow,wrist and hand”
in J Biomechanics with the x axis pointing forward instead of ponting
to the right like in the article you send me. That makes much more
sense because I was wondering how a force of 2000N could be applied
in anterior-posterior direction ( unless you have a humerus
retroversion of app. 90°).I will try you advices with the coordinate
systems and probably ask lots of more questions, soon.
Cu Peter
