The Turning: The thoracic spine in connecting the kinetic chain

 I had a client just this past week during the NYC marathon invert his ankle when he looked back to snap  a selfie with the crowd behind him.  What i discussed today was the likely mechanism -- his thoracic rotation to that side sucked when I examined him and he had loss of internal hip rotation on that side.  The motion had to go somewhere , sadly it was one degree of ankle supination too much this time.
