One of the wonderful aspects of Acupuncture, no matter the style, is that it generally works well for most conditions.
Depending on your health goals, the health condition you are experiencing, and your personality, some styles may be more appropriate for you than others.
Practitioners will have different levels of training in one or more systems, and will be either comprehensively trained or focused-trained.
Comprehensively-trained practitioners have two to five years of training in acupuncture and Traditional Chinese Medicine. They understand the basics of Western anatomy and physiology, and are trained to look at your condition from an environmental and systems approach. Their strength is the ability to develop a comprehensive picture of your particular pattern of harmony or disharmony. From this analysis, they determine the strengths and weakness in your system and treat not only the immediate problem that brings you into their clinic, but also address underlying issues that will improve overall health outcomes over time. In Traditional Chinese Medicine this is called treating the branch (Biao) and the root (Ben). Comprehensively trained practitioners are concerned about overall health cultivation in addition to treating the immediate health concern.
The focused-trained practitioner has learned acupuncture as a technique to be used in addition to their main scope of practice. Their courses vary from 200 to 400 hours, and in general this type of acupuncture used is geared to pain and symptom relief.
