<r>Imagine a planar mechanism consisting of just two links connected by a single pin joint. To change the angle between the two links, you would need to connect a motor at the joint which applies equal and opposite moments on the links.... this is analogous to joint moment.<br/> <br/> Now instead of...

Would the JointReaction analysis results be the same for RRA and CMC data??

The JointReaction analysis does not work when I load the actuators, controls and walk states for the RRA. Am I doing something wrong here, or was the tool meant to work only when CMC data was loaded??

Yup, got it.... Thanks Dan!!

Is the joint reaction analysis available with the current version of OpenSIM (1.8.1)... I could not find the option in the Analyze Tool....

<t>Hi,<br/> <br/> When we talk about the total knee flexion/extension moment of all the muscles crossing the knee joint, about which anatomical point are we calculating moments. Also, we would have to resolve the net moment of all the muscles along a certain direction to specifically isolate the fle...

<t>Hi,<br/> <br/> During CMC, is a single cost function used for the entire model (both sides) or does the source code allow us to modify the cost function for a subsection of the model, like specify different functions for the right or left side or even for each joint??? Thanks!!<br/> <br/> Ananth ...

<t>Hi<br/> <br/> Is it possible to track the 'global' coordinates (in the lab frame), of a certain point like the origin/insertion point of a muscle, center of mass of a segment etc. for each time-step of a walking trial? I can get the data in the local frames from the XML files, but i want to track...

<t>Hi,<br/> <br/> I am trying to simulate the action of a knee brace with a rotary actuator which applies a pure torque about the joint axis. Now, this means that the moments applied to the femur and the tibia will be equal in magnitude and opposite in direction. So in the CMC actuators file, under ...
