Acupuncture

Acupuncture (from Lat. acus, "needle" (noun), and pungere, "prick" (verb) is one of the main branches of Traditional Chinese Medicine (others being herbal medicine and tui na). It is a therapeutic technique from that framework intended to restore health and well-being. The term acupuncture is often used by Westerners to refer to Chinese medicine generally. The technique involves the insertion of needles into "acupuncture points" on the body by trained practitioners. The needles most commonly used in present-day practice are made of stainless steel and are of approximately the same diameter as a medium thickness guitar string (from approximately .01" to .02"). Although the clinical efficacy of this practice is debated, the traditional theory underlying its mechanisms has no basis in modern scientific conceptions of physiology and is therefore considered by its critics to be a pseudoscience. While many of its practitioners and proponents promote it in a modern, clinical manner, acupuncture and related practices predate modern concepts of science.
In China, the practice of acupuncture can perhaps be traced as far back as the 1st millennium BC, and archeological evidence has been identified with the period of the Han dynasty (from 202 BC to 220 AD). The practice spread centuries ago into many parts of Asia; in modern times it is a component of traditional Chinese medicine (TCM), and forms of it are also described in the literature of traditional Korean medicine where it is called chimsul. It is also important in Kampo, the traditional medicine system of Japan.
Recent examinations of Ötzi, a 5000 year old mummy found in the Alps, have located over fifty tattoos on Ötzi's body, some of which are located on acupuncture points that would today be used to treat ailments Ötzi suffered from. Some scientists believe that this is evidence that practices similar to acupuncture were practiced elsewhere in Eurasia during the early bronze age.

Warming an acupuncture point, typically by moxibustion (the burning of mugwort), is a different treatment than acupuncture by itself and is often, but not exclusively, used as a supplementing treatment. The Chinese term zhe¯n, commoned used to refer to acupuncture, comes from zhen meaning "needle", and jiu meaning "moxibustion". Moxibustion is still used in the 21st century to varying degrees among the schools of traditional Chinese medicine. For example, one well known technique is to insert the needle at the desired acupuncture point, attach dried mugwort to the external end of an acupuncture needle, and then ignite the mugwort. The mugwort will then smolder for several minutes (depending on the amount adhered to the needle) and conduct heat through the needle to the tissue surrounding the needle in the patient's body.
Most modern acupuncturists use disposable stainless steel needles of very fine diameter (approximately .015"), sterilized with ethylene oxide or by autoclave. The upper third of these needles is wound with a thicker wire (typically bronze) to stiffen the needle, provide a handle for the acupuncturist to grasp while inserting the needle, and also provide a surface to which dried mugwort will more easily adhere.

Theory

Acupuncture treats the human body as a whole that involves several "systems of function" that are in many cases associated with (but not identified on a one-to-one basis with) physical organs. Some systems of function, such as the "triple heater" (San Jiao, also called the "triple burner") have no corresponding physical organ. Disease is understood as a loss of homeostasis among the several systems of function, and treatment of disease is attempted by modifying the activity of one or more systems of function through the activity of needles, pressure, heat, etc. on sensitive parts of the body of small volume traditionally called "acupuncture points" in English.

Treatment of acupuncture points may be performed along the twelve main or eight extra meridians, located throughout the body. Ten of the main meridians are named after organs of the body (Heart, Liver, etc.), and the other two are named after so called body functions (Heart Protector or Pericardium, and San Jiao). The two most important of the eight "extra" meridians are situated on the midline of the anterior and posterior aspects of the trunk and head. The twelve primary meridians run vertically, bilaterally, and symmetrically and every channel corresponds to and connects internally with one of the twelve Zang Fu ("organs"). This means that there are six yin and six yang channels. There are three yin and three yang channels on each arm, and three yin and three yang on each leg.
The three yin channels of the hand (Lung, Pericardium, and Heart) begin on the chest and travel along the inner surface (mostly the anterior portion) of the arm to the hand.

The three yang channels of the hand (Large intestine, San Jiao, and Small intestine) begin on the hand and travel along the outer surface (mostly the posterior portion) of the arm to the head.

The three yang channels of the foot (Stomach, Gallbladder, and Bladder) begin on the face, in the region of the eye, and travels down the body and along the outer surface (mostly the anterior and lateral portion) of the leg to the foot.

The three yin channels of the foot (Spleen, Liver, and Kidney) begin on the foot and travel along the inner surface (mostly posterior and medial portion) of the leg to the chest or flank.

The movement of qi through each of the twelve channels is comprised of an internal and an external pathway. The external pathway is what is normally shown on an acupuncture chart and it is relatively superficial. All the acupuncture points of a channel lie on its external pathway. The internal pathways are the deep course of the channel where it enters the body cavities and related Zang-Fu organs. The superficial pathways of the twelve channels describe three complete circuits of the body.

The distribution of energy through the meridians is said to be as follows: Lung channel of hand taiyin to Large Intestine channel of hand yangming to Stomach channel of foot yangming to Spleen channel of foot taiyin to Heart channel of hand shaoyin to Small Intestine channel of hand taiyang to Bladder channel of foot taiyang to Kidney channel of foot shaoyin to Pericardium channel of hand jueyin to San Jiao channel of hand shaoyang to Gallbladder channel of foot shaoyang to Liver channel of foot jueyin then back to the Lung channel of hand taiyin

Traditional Chinese medical theory holds that acupuncture works by normalizing the balance of qi "vital energy" throughout the body. Pain or illnesses are treated by attempting to remedy local or systemic accumulations or deficiencies of qi. Pain is considered to indicate blockage or stagnation of the flow of qi, and an axiom of the medical literature of acupuncture is "no pain, no blockage; no blockage, no pain".

Many patients claim to experience the sensations of stimulus. This kind of sensation was historically considered to be evidence of effectively locating the desired point. There are some electronic devices now available which will make a noise when what they have been programmed to describe as the "correct" acupuncture point is pressed.

The acupuncturist will decide which points to treat by thoroughly questioning the patient, and utilizing the diagnostic skills of traditional Chinese medicine which include observation of the left and right radial pulses at three levels of imposed pressure and analysis of the tongue coating, color and the absence or presence of teeth marks around the edge.

There are also theories being developed to explain effects observed for acupuncture by within the orthodox Western medical paradigm.

There are various schools of acupuncture theory, including:

• the original TCM method
• Zang Fu theory
• medical acupuncture
  
  

An example of acupuncture practice


In western medicine, vascular headaches (the kind that are accompanied by throbbing veins in the temples) are typically treated with analgesics such as aspirin and/or by the use of agents such as niacin that dilate the affected blood vessels in the scalp, but in acupuncture a common treatment for such headaches is to stimulate the sensitive points that are located roughly in the center of the webs between the thumbs and the palms of the patient. The theory of acupuncture states that these points are associated with the digestive system (the large intestine), and that one is acting to relax some kind of hyperactive state in the gastro-intestinal system. Three kinds of sensation are associated with this treatment, sensations that are stronger than those that would be felt by a patient not suffering from a vascular headache: (1) Extreme sensitivity to pain at the points in the webs of the thumbs. (2) In bad headaches, a feeling of nausea that persists for roughly the same period as the stimulation being administered to the webs of the thumbs. (3) Simultaneous relief of the headache.
Benefits (proven and purported)

Although accepted as a medical treatment in Asia for millennia, acupuncture's arrival in the West has sparked much controversy. Acupuncture has eluded scientific explanation to some degree. However, in 1997, the NIH issued a consensus statement on acupuncture that concluded that
there is sufficient evidence of acupuncture's value to expand its use into conventional medicine and to encourage further studies of its physiology and clinical value.

The NIH statement noted that the data in support of acupuncture are as strong as those for many accepted Western medical therapies and added that the incidence of adverse effects is substantially lower than that of many drugs or other accepted medical procedures used for the same condition. For example, musculoskeletal conditions, such as fibromyalgia, myofascial pain, and tennis elbow... are conditions for which acupuncture may be beneficial. These painful conditions are often treated with, among other things, anti-inflammatory medications (aspirin, ibuprofen, etc.) or with steroid injections. Both medical interventions have a potential for deleterious side effects but are still widely used and are considered acceptable treatments.

The NIH consensus statement noted that there is clear evidence that needle acupuncture is efficacious for adult postoperative and chemotherapy nausea and vomiting and probably for the nausea of pregnancy... There is reasonable evidence of efficacy for postoperative dental pain... reasonable studies (although sometimes only single studies) showing relief of pain with acupuncture on diverse pain conditions such as menstrual cramps, tennis elbow, and fibromyalgia.
In 1999, clinical researchers reported that inserting the fine needles into specific body points triggers the production of endorphins.
