A brief excerpt from the site:
"All he was trying to do was ease her chronic back pain, but when Dr. Stuart Meloy placed an electrode into one patient’s back, she groaned.
Not in pain, but in delight.
“‘This is a direct quote – she said, ‘You’re going to have to teach my husband how to do that’,’ Meloy, an anesthesiologist and pain specialist in Winston-Salem, North Carolina, said in a telephone interview.”
I don’t even know what to add . . . recreational spine toys, anyone?
