Years ago my GP referred me to the neuro across the street from him for a "c6/c7 pinched nerve". He pulled out this black device that did the EMG. I thought it was a joke, I'd been in the antique business and it looked like one of the quack medicine devices from the turn of the 20th century. He prescribed me an equally archaic traction device to stretch my vertebrae out for thirty minutes a day--otherwise--he'd "be seeing me for surgery." That was in my pre-TMS knowledge days; now I know the cause was was Barbara, and not a pinched nerve. These devices may be useful for DX'ing electrical short circuits in a house or a car's electrical system, but maybe not sophisticated enough to dx, mindbody dis-ease in the convoluted gray matter of homo-sapiens sapiens.
