Hi Tim,

Thanks for sharing the Induced Acceleration analysis.

I am interested in calculating the induced acceleration of the various body segments in a model. Is this possible to add to the analysis?

Thank you,

Allison Hall

Hi Allison,

I suppose in theory that if you know the induced acceleration of a joint and the location of the center-of-mass of the segment with respect to the joint, then you could find the induced acceleration of the segment. However, this is not currently implemented. In the next version (which I will release soon), there is the capability to calculate the induced segment power, based on Fregly (1996): A state-space analysis of mechanical energy generation, absorption, and transfer during pedaling), so maybe that could suffice.

Cheers,
Tim

Hi Tim,

Thanks for the update. I would really appreciate the option to perform a segment power analysis (which is why I want to calculate the segment acceleration).

Do you have a time frame for the next release?

Thank you,

Allison

The segment power analysis is now available with the IndAccPI plugin. Note that you must use this plugin with version 2.4 (VC10) build of OpenSim.

Hi,Tim Dorn
Is the "Segment power analysis" option available in version 3.2?
