RE: Problem of rotated model after scaling
<t>Hi Sylvia,<br/> I had a similar problem with a crumpled skeleton after scaling with the BoLegs1793.osim model. The problem turned out to be that the pelvis only had rotational degrees of freedom and not translational. My *.TRC file data was ok but there was a translational offset which the model ...

RE: Locking subtalar and mtp joints
<t>Hi Ruoli,<br/> I've been doing RRA/CMC on the gait2392 and LLM2010 models and haven't locked any of the coordinates. The resulting foot kinematics seems to match reasonably well with my original kinematics from our Vicon motion capture system. My vicon model has a solid foot section so only produ...

RE: Cost function.
<t>Hi Ayman,<br/> I see this thread is a couple of years old now and that OpenSim 2.0 is now released. Is it now possible to edit the cost function used in CMC? <br/> <br/> I am currently running gait data through OpenSim 2.0 with the gait2392 and LLM2010 models and using the CMC tool to generate mu...

RE: Choice of Muscle Specific Tension
<t>Hi Edith,<br/> Thanks for your reply and paper reference.<br/> <br/> Maybe I am getting confused with this issue but in my mind the fact that the value of 61N/cm2 was calculated from comparing elderly (and hence small muscled) cadaveric data of PCSA to younger data for moment curves shows that it...

RE: RRA/CMC problems
Hi Edith,
Running the CMC tool from the windows command line worked a treat. I have now sucessfully run both RRA and CMC for my dataset.
Thanks for your help,
Andy

RRA/CMC problems
<t>Hi,<br/> <br/> I am having issues with OpenSim crashing and shutting down when I try and run the CMC tool with this Lower Limb Model through the OpenSim GUI.<br/> <br/> From my (brief) experience of using OpenSim I have learnt to use the CMC tool twice for the purposes of residual reduction (RRA)...

Increasing Muscle Strength for CMC
<t>In the recent release of the E.Arnold Lower Limb Model 2010 there is a second, stronger version of the model that is described as CMC friendly. I've been doing some work trying to compare the CMC muscle activations to recorded EMG in normal gait and, similar to other folk I have spoken to, I have...

Choice of Muscle Specific Tension
<t>Am interested in the choice of 61N/cm2 for the muscle specific tension in OpenSim models (I personally have been using the gait2392 and E.Arnold's Lower Limb 2010 model). I see from her paper (Arnold 2009) that this value comes from Delp's PhD work (Delp 1990 p.34). If I understand it correctly t...
