It wasn’t Waldinger that applied the laser. It was the second author of the paper. What kind of questions would you ask? Just curious.
I want to know if it matters exactly what laser is used. If I need to use the laser I bought more often since it’s probably weaker. And if you should move it around. And if it always works. Stuff like that.
Maybe you should set an appointment with the second author. I don’t think Waldinger is involved in that. He’s a psychiatrist not physical therapist. But the other guy does seem to know what he’s doing since he got results with the patient in paper.
