Hello
we can model a seated human under whole body vibration in opensim? how?
Thanks

Hello

I want to simulate pain in muscles. my purpose is escape of test on patients.
i can achieve to it in open sim? how? please help me.

and can i simulate fatigue in open sim?

Hello if thorax rotation relative pelvis was 30 degree, can i rotate L5 to L1 , 20 degree and T1 to L5, 10 degree? this rotation division is possible!? because in models in opensim respiratory, spine and thorax are a rigid body that rotate together in coordinate changing ability of opensim. Thanks M...

Thank you very much Dimitar
but if i have not a constant force, force is depend to time, how write code for this?

Hi I decided to instead of modeling of flexible pole, measure the perpendicular forces applied by the grip to the hand by FSR sensors. i will record forces per time as real time and synchronized to my setup and then i want to simulate this measured force in opensim as the force applied to specified ...

Hi Dimitar
Thank you very much. your helps was very useful.

Hi Hossein In opensim 3.3, muscle moment arm ploted as directly result , is this result basically formulation r = derivative muscle tendon length / derivative joint angle where, muscle tendon length = tendon length + fiber length * cos (pennation angle) that Mr.Lee say? and if i want to export my re...

Hi Thank you dear Dimitar. i will record body(hand,..) and bar motion (marker tracking) , and have a force plat ( grf,moment and cop), wind forces are not my test results. my purpose is evaluation muscle moment arms. { 2 question: -i can plot moment arms in opensim (image) , but i want to attach mod...

Hi Demitar thank you very much. i have some questions about your reply, please answer me -please look at image that attached, my segment is a grip with two wing, also they are rigid, but their connection is like spherical joint of 3 dof, and grip hold by hand, and hand also has a little linear motio...

Hi I am Mehrdad Davoodi, and master student in Sharif university in Tehran. I am intrested in the joint moments, and muscle forces than my model, and i will test with force plate, how i use force plate data in opensim? and i have a full body model that upper limbs ( especially shoulder ,..), where i...
