Hmm... never heard of this to be honest with you. If you are already willing to take classes and pay, you should consider physical therapy instead. That's just my view.
Massage therapy is quite popular. One would choose to take physical therapy if they wanted to go into that field and get a degree that would take longer. Physical therapy is entirely different from massage therapy. Massage therapy is a shorter and less expensive degree and would be more catered to what she wants to do.
