Calculate Muscle Tendon Lengths using OpenSim
« on: August 12, 2016, 05:46:09 PM »
Chicago has code that already does this.  I'm curious about how much interest there is in this and how many people would use it for clinical purposes.

Replies are welcome.

This analysis would call on OpenSim (free download) to run muscle tendon length (MTL) estimations based on gait trials. The program applies the kinematic data to the OpenSim model and outputs patient MTLs compared to optimal MTLs. We display this data as a graph for each muscle of interest over one gait cycle. The Y axis is 'Normalized MTL (%)' so a value of 1 would mean that the MTL is operating at an optimal lenth, below 1 would be short and above 1 would be long.
