After healing a stress fracture should I use Alter-G after I start running outside?

Let's say you have been injured. You've been a good little patient. You waited around, you have done nothing. You have endured a frustrating period of boredom. And you finally started running again. That’s great!
 
Today's episode came from a webcam call I did with a recovering runner. She has a stress fracture but her foot was good enough to run outside. 

The question was  about whether or not an injured runner should keep using something like an AlterG treadmill to maintain running fitness while continuing to heal and recover from a stress fracture.
 
After healing a stress fracture, should I use the AlterG treadmill even after I've started running outside? 
 
Well, that's a great question, and that's what we're talking about today on the Doc On The Run Podcast.
