Kevin,
I am very familiar with one of the articles. I was there when the one by
Schuster and D'Amico was being done. Yes, you are correct. It was relative
to the ground, and the proximal segments everted more with pronation, so
the net effect was inversion. Sorry, I can't help you with the other ones.
Sincerely,
Stanley
