I think it's called electro-acupuncture and I found it perchance as the acupuncturist just automatically did it. From my experience they hook up current to some of the needles and this results in extra stimulation. They also used electrical pads with a moist cloth and applied this to my abdomen and lower back and neck area, which was like lots of little needles stimulating the area, but without feeling like the other needles..if that makes sense. Apart from looking like a science experiment (as dh thought) it has been quite good! Hopefully see results soon! X
