PTs doing EMG?

My wife just had an EMG for persistent arm pain, and ortho referred her to "Dr. Smith". I thought he was a neurologist, but, when I saw the report, he was "PT, ScD", and did introduce himself as "Dr. Smith".

Is this common, for PTs to do EMGs and such? He did diagnostic, only, though - didn't do any nerve blocking or anything.

(And it was like pulling teeth to get my wife to do anything - I'm just a "dumb ER doc", but, man, it was getting to me!)

Thanks, fellas.
