A study entitled “Influence of different durations of electroacupuncture stimulation on skin blood flow and muscle blood volume” was published in the BMJ Acupuncture in Medicine (Acupunct Med. 2014 Jan 3. doi: 10.1136).
Electroacupuncture, used in this study is a modern acupuncture technique, in which needles are inserted into acupuncture points and are then attached, using small clips, to a device that generates continuous electric impulses. Electroacupuncture is often the preferred form of acupuncture technique in many acupuncture research settings because the stimulation to each subject can be more easily standardized among subjects, in comparison to classical manual acupuncture.
In clinical practice, many expert acupuncturists tend to use manual needling procedures. Although more time consuming and technically more demanding, the stimulation can be individually adjusted point by point, for each patient with manual acupuncture procedure. (read more about Acupuncture Styles)
