Electro-acupuncture is a safe method of providing sustained gentle needle stimulation throughout the course of the treatment. I have advanced level training in the use of electro-acupuncure for a variety of painful conditions from neck pain to depression.
In clinic I use the AS SUPER 4 digital, which belongs to the new generation of needle stimulators which use safe, proven programs and electrical parameters. Sometimes I use sticky pads in place of the needles (like the ones on TENs machines). This is helpful for patients who are particularly needle phobic.
