Do I Need a Bone Stimulator for a Grade 5 Stress Fracture?

I just did a second opinion consultation with a runner who called and said she was diagnosed with a grade five stress fracture.  The doctor didn't actually explain what that meant. He just said it was serious. Stress fracture are rated by severity from grade one through a grade five. Grade five is obviously the worst to runner. She wanted to know if she needed a bone stimulator since her stress fracture was serious. Do I need a bone stimulator for a grade five stress fracture? That's what we're talking about today on the Doc On The Run podcast.
