Electro-acupuncture is the term used to refer to the application of a pulsating electrical current to acupuncture needles, or even without needles, to acupuncture points on the body. Using a gentle electrical current in conjunction with, or instead of, acupuncture needles, is an alternative way to stimulate the point and enhance the qi. The procedure for electro--acupuncture usually involves the needles inserted as in a traditional treatment, but a small electrode is attached to them. This electrode provides a gentle vibration that stimulates the qi running through these points. It is often very soothing to the patient, providing a soft humming and, essentially, a more fluid treatment. Also, electro--acupuncture treatments are often shorter than regular acupuncture treatments due to the continued and often stronger stimulus. While electro--acupuncture may be used as a component of almost all acupuncture treatments, it has garnered especially good results regarding the treatment of neurological diseases, chronic pain, spasms and paralysis. Also, holistic sports medicine commonly uses electro--acupuncture for injuries.
