Back to the original topic. Look at this pic, it's part of a BVH where the guy is getting up. Here i would expect the arms to be pushing off the ground but instead the arms are all curled up and distorted. That's what i want to be able to restore. i want to restore the original animation of the arms.

By the way i've been imporiting the BVH
choosing To Alight arms in X-Axis, and Scale Automatically( 2 pop up windows that poser gives me)
