A customer is asking how to extract reaction forces on thoracic spine vertebra, specifically T7-T8 and T9-T10. I know we can place frames within a rigid body and can extract forces. Can we use similar logic to extract such reaction forces from thoracic spine vertebral joints?
Use AnyForceMomentMeasure2 object to compute an equivalent load in the estimated location of T7T8 joint. I expect it to be roughly corresponding to the joint load.
Interpolate between T12L1 / C7T1 joint loads - the lower the joint the more mass it has to carry.
Wait until we release the thoracic spine model, which is coming in some foreseeable future.
