Electroacupuncture is a form of acupuncture in which pairs of acupuncture needles are attached to a device that generates continuous electric pulses between them. Another term is Percutaneous Electrical Nerve Stimulation (PENS).
According to Acupuncture Today, a trade journal for acupuncturists, "Electroacupuncture is quite similar to traditional acupuncture in that the same points are stimulated during treatment. As with traditional acupuncture, needles are inserted on specific points along the body. The needles are then attached to a device that generates continuous electric pulses using small clips. These devices are used to adjust the frequency and intensity of the impulse being delivered, depending on the condition being treated. Electroacupuncture uses two needles at time so that the impulses can pass from one needle to the other. Several pairs of needles can be stimulated simultaneously, usually for no more than 30 minutes at a time.
According to the principles of traditional Chinese medicine, illness is caused when qi does not flow properly throughout the body. Acupuncturists determine whether qi is weak, stagnant or otherwise out of balance, which indicates the points to be stimulated. Electroacupuncture is considered to be especially useful for conditions in which there is an accumulation of qi, such as in chronic pain syndromes or in cases where the qi is difficult to stimulate."
In this regard this particular practice can be used to augment the use of regular acupuncture and can restore health and well-being and is particularly good for treating chronic pain.
