Shoulder Elevation

Hello Sir, I am doing comparison of different shoulder elevation angles. But i have a problem about the model elevation angle in model view did not change with the angles. Also I have tried with the velocity added to see if the model move but the joint did not moving.

I have adjusted the sternoclavicular joint value in the mannequin. Am I doing with the right joint. Image below as the reference for my analysis.

Hi

Sorry for the slow reply,

I am unsure which model you are using for this?

It is not all models which will take notice of the value set in the mannequin file, please try the FreePostureModel for this and change the SternoClavicularElevation property in the mannequin file.

Please also note that this value will not change the loading position, it is only after solving kinematics this will have an effect

Best regards

Hello Sir, Thank you for your kindness reply. Does ‘this value will not change the loading position, it is only after solving kinematics this will have an effect’ meaning that result of holding this position or postures in period time (manipulated) will be the same?

Thank you very much sir

Hi

Sorry for slow reply,

What i meant was this value only has an effect once the kinematics has been resolved.

The model does not have a fatigue model built in as default so it will provide the same results if the position is held for a long or short time period, this is not accounted for. This is something which is possible to do but requires the user to implement a fatigue formula for the muscles.
