Hello to every body!
I am to Anybody software.
My goal is to calculate Muscle Forces in Seated Human Model of spine.
I want to calculate forces in different postion i.e different
PelvisThroxExtenion angle=0,30,45,60,90 degrees in flexion.
I have tried but i get alway same force even change this angel to -90
degree.
Can anyone help me.
I hope this will not bother you people
John
Hi John
The short answer is that this is because the angle has not been changed.
In many of the model in the repository it is not all the angles in the
mannequin.any which are being used for actually driving the model
kinematically when running an analysis. In the case of the SeatedHuman model
this is because the PlevisThroaxExtension is driven by the position of the
backrest and not by the angle in the Mannquin.any file. Which dof are being
driven directly from the mannequin file depends on the application.
In all models these angles are however always used for setting the initial
positions.
So if you want to change the pelvisthoraxExtrension you will need to
disconnect the subject from the backrest. This is done in the
JointAndDriver.any file., There is a recent posting about how this can be
done please see this message:

Hi,
I checked it but it does not work.
Can you have look on that.

Hi John
I you have done the modifications listed below to the model, it will
decouple the thorax from the backrest. If you do this, i am sure the results
will not be the same for all PelvisThroaxExtensiton angles specified in the
mannequin.any file.
If you have problems getting this to work, you could choose to simply change
the backrest angle by changing the variable “DrvPos.SeatBackRestRotZPos”,
this will also change the pelvisthoraxextension angle, although this will be
indirectly.
Modification list:
a. Outcomment the kinematic constraint between the backrest and the thorax
this is the object named “BackRestThoraxEq” this will remove the
constraint the make the thorax follow the backrest.
b. Instead add a driver for the pelvis thorax extension this is in the
“PostureDriver” it is already there, it just need to be enabled.
c. You need to consider if the support forces between the backrest and the
spine should remain. If you would like to switch them off you need to out
comment the following include statement in the Support.any file “#include
“BackRestSuppport.any””
I hope this helps you move on

Hi,
May be its bothering you.
But i would like you to just check it.
when i do what you suggested it gives error and when i fix the error
,the InversDynamic analysis gives error.
i just want to Know the musle forces ( already checked with sitting
position)at different Flexion positions.It should be static analysis.
Sorry for bothering.

Hi John
Sorry about the slow reply.
I have tested the steps I listed and you are right, it does not work without
a few more modifications.
I have uploaded a new version of the JointAndDrivers.any file which should
solve the problem. The file can be found in the SeatedHumanFreeThorax"
folder, in the file section of the group.
This should allow you to change the pelvisthoraxextension angle in the
mannequin file. Please note that depending on the angle you insert, it may
happen that the arms will not be able to reach the arm rests and you will
get a kinematic error.
Best regards
