I guess the next step is to set up blind studies, where one doctor sets up the apparatus for either a real or sham treatment, and then leaves the room, then another doctor comes in with the family and runs the treatment without knowing which treatment is being administered. Alternatively, the treatment is administered (or not) by a second doctor in another room who can't communicate with those in the room.
