Re: Simulation results - Force of m.psoas
Thank you for your answer. I'm sorry I did not mention that the simulation is performed during walking and not stance. In this phase of the gait cycle (terminal stance to initial swing) the knee and the hip flex. I plotted the hip and knee angles and the spring force. From these two pictures I can s...

Simulation results - Force of m.psoas
Hi, I have a question concerning the results of my studies: I have weakened the rectus femoris (reduced the controls to 10% of their maximum value) and implemented a path spring parallel to the rectus femoris muscle in the model 'Gait2354' to support the weakened muscle. I focused on the phase termi...

Re: Problems performing IAA with Gait2354 model
This is the Setuo File I used. Maybe it contains a mistake?

Re: Problems performing IAA with Gait2354 model
I thought About this Posting: https://simtk.org/plugins/phpBB/viewtopicPhpbb.php?f=1398&t=8339&p=0&start=0&view= But Maybe I did not understand it correctly. When I don't Change the external load file from Point force to Body force, I get valid results for the constraint reaction Forces which match ...

Problems performing IAA with Gait2354 model
Hi, I am trying to make an IAA with the model 'Gait2354_Simbody'. I have already made an IAA with the model 'Gait10dof18musc'. I found out that one has to Change the external loads file from Point force to Body force (applied to Calcaneus) to get valid results in the induced constraints file. (https...

Difference between Gait Models
Hi,
Could somebody explain me the difference between the Models 'subject01_simbody' and 'subject01_scaledOnly'?
And when do I have to perform RRA in my analysis?
Thank you very much.
Regards
Pia

Change isometric force of muscles
Hi, I implemented a path spring parallel to the rectus femoris muscle in the Gait10dof18musc model. Now I want to weaken the isometric force of the rectus femoris muscle to see the effect of the spring. In the model the rectus femoris has a maximum isometric force of 1.169N. I changed it to 292.25N ...

Verifying IAA induced constraints
Hi, I try to do a verification of induced constraints (rolling-without-slipping) versus experimental GRF, during Walking. I have a Problem with the verification of the Moments/Torques. I read the post of Adam Yoder (https://simtk.org/plugins/phpBB/viewtopicPhpbb.php?f=1398&t=8339&p=0&start=0&view=&s...

Report constraint reactions IAA
Hi, I am working with the model 'Gait10dof18musc'. I am interested in the muscle contributions to the accelerations, so I performed a Induced Acceleration Analysis. To run the IAA I think I need to add the Rolling on Surface Constraint. I made a Setup File, which I attached to this message. I also a...
