Essentials of Electroacupuncture, 3rd Edition adds new and valuable resources to existing textbooks. It is a formal textbook, which provides complete and detailed instructions how to perform electro-acupuncture for stroke, polyneuropathy, spinal disc disease, other painful neurological, musculoskeletal diseases, and functional disorders. There are 6.8 million stroke survivors and 20 million polyneuropathy patients in the United States. Electro-acupuncture brings clinical remissions much earlier than traditional acupuncture, especially when Extraordinary Channels are used. This makes electro-acupuncture the preferred procedure in terms of time and cost spent for treatments. The effectiveness of electro-acupuncture makes a positive contribution to the healthcare spending in which the cost of healthcare on the national scale rises every year at an exponential rate. Also early clinical remissions from electro-acupuncture reduces the costs of monthly drug refills and equipment rentals such as wheel chairs and walkers. The author is a board-certified internist, and he maintains a pain management acupuncture practice in Burbank, California. In this updated edition, Dr. Choi articulates the theoretical and technical basis of the practice, detailing its history and development, diagnostic principles, and techniques for safe and effective treatment. The new edition adds to explanations and prescriptions related to the extraordinary channels, the four types of body constitution, and pulse diagnosis. When the extraordinary channels and the diagnostic schemes are used, clinical remissions arrive earlier. The importance of the source of channel energy and its movement is stressed with new selections from the writings of legendary acupuncturists Pian Que and Hua Tuo. The result is a more comprehensive explanation of the practice and theory of acupuncture as a whole, and electro-acupuncture specifically. A valuable guide and instruction book for practicing acupuncturists, students, and those interested in Chinese traditional medicine, Essentials of Electroacupuncture, 3rd Edition honors past masters of acupuncture while looking toward the future.
