Acupuncture (and its related Moxibustion) are practiced medical treatments that are over 5,000 years old. Very basically, Acupuncture is the insertion of very fine needles, (sometimes in conjunction with electrical stimulus), on the body's surface, in order to influence physiological functioning of the body.
Acupuncture can also be used in conjunction with heat produced by burning specific herbs, this is called Moxibustion. In addition, a non-invasive method of massage therapy, called Acupressure, can also be effective.
The first record of Acupuncture is found in the 4,700 year old Huang Di Nei Jing (Yellow Emperor's Classic of Internal Medicine). This is said to be the oldest medical textbook in the world. It is said to have been written down from even earlier theories by Shen Nung, the father of Chinese Medicine. Shen Nung documented theories about circulation, pulse, and the heart over 4,000 years before European medicine had any concept about them.
As the basis of Acupuncture, Shen Nung theorized that the body had an energy force running throughout it. This energy force is known as Qi (roughly pronounced Chee). The Qi consists of all essential life activities which include the spiritual, emotional, mental and the physical aspects of life. A person's health is influenced by the flow of Qi in the body, in combination with the universal forces of Yin and Yang . (I will discuss Yin and Yang a little later). If the flow of Qi is insufficient, unbalanced or interrupted, Yin and Yang become unbalanced, and illness may occur. Qi travels throughout the body along "Meridians" or special pathways. The Meridians, (or Channels), are the same on both sides of the body (paired). There are fourteen main meridians running vertically up and down the surface of the body. Out of these, there are twelve organ Meridians in each half of the body (remember they are in pairs). There are also two unpaired midline Meridians. There will be a diagram of Acupuncture points for treating diseases of the Meridians at the end of the digestive system paper. (See Appendix 1). The acupuncture points are specific locations where the Meridians come to the surface of the skin, and are easily accessible by "needling," Moxibustion, and Acupressure. The connections between them ensure that there is an even circulation of Qi, a balance between Yin and Yang.
Energy constantly flows up and down these pathways. When pathways become obstructed, deficient, excessive, or just unbalanced, Yin and Yang are said to be thrown out of balance. This causes illness. Acupuncture is said to restore the balance.
Yin and Yang is an important theory in the discussion of Acupuncture treatment, in relation to the Chinese theory of body systems. As stated earlier Qi is an energy force that runs throughout the body. In addition, Qi is also prevalent throughout nature as well. Qi is comprised of two parts, Yin and Yang. Yin and Yang are opposite forces, that when balanced, work together. Any upset in the balance will result in natural calamities, in nature; and disease in humans. Yin is signified by female attributes, passive, dark, cold, moist, that which moves medially, and deficient of Yang. Yang is signified by male attributes, light, active, warm, dry, that which moves laterally, and deficient of Yin. Nothing is completely Yin or Yang. The most striking example of this is man himself. A man is the combination of his mother (Yin) and and his father (Yang). He contains qualities of both: This is the universal symbol describing the constant flow of yin and yang forces. You'll notice that within yin, there is Yang, and within Yang, there is the genesis of Yin. Whether or not you believe in Taoist philosophy, (which all this is based on), one thing is indisputable: Acupuncture works.
Acupuncturists can use as many as nine types of Acupuncture needles, though only six are commonly used today. These needles vary in length, width of shaft, and shape of head. Today, most needles are disposible. They are used once and disgarded in accordance with medical biohazard regulations and guidlines. There are a few different precise methods by which Acupuncturists insert needles. Points can be needled anywhere in the range of 15 degrees to 90 degrees relative to the skin surface, depending on the treatment called for. In most cases, a sensation, felt by the patient, is desired. This sensation, which is not pain, is called deqi (pronounced dah-chee). The following techniques are some which may be used by an Acupuncturist immediately following insertion: Raising and Thrusting, Twirling or Rotation, Combination of Raising/Thrusting and Rotation, Plucking, Scraping (vibrations sent through the needle), and Trembling (another vibration technique). Once again, techniques are carefully chosen based on the ailment.
There are a few related procedures that fall into the range of Acupuncture treatments. The first is Electro-Acupuncture. This is the using of very small electrical impulses through the Acupuncture needles. This method is generally used for analgesia (pain relief or prevention). The amount of power used is only a few micro amperes, but the frequency of the current can vary from 5 to 2,000 Hz. The higher frequencies are generally used for surgery (usually abdominal), and the lower frequencies for general pain relief. The first reported successful use of Electro-Acupuncture was in 1958 in China for a tonsillectomy.
Today, it is a common method of surgical analgesia used in China. Other methods for stimulating Acupuncture points have used Lasers and sound waves (Sonopuncture). A very commonly used treatment in the United States is Auriculotherapy or Ear Acupuncture. The theory is that since the ear has a rich nerve and blood supply, it would have connections all over the body. For this reason, the ear has many Acupuncture points which correspond to many parts and organs of the body. Auricular Acupuncture has been successful in treating problems ranging from obesity to alcoholism, to drug addiction. There are numerous studies either completed, or currently going on which affirms Auricular Acupuncture's effectiveness. (These will be mentioned in detail later on in the paper.)
Another popular treatment method is Moxibustion, which is the treatment of diseases by applying heat to Acupuncture points. Acupuncture and Moxibustion are considered complimentary forms of treatment, and are commonly used together. Moxibustion is used for ailments such as bronchial asthma, bronchitis, certain types of paralysis, and arthritic disorders.
Cupping is another type of treatment. This is a method of stimulating Acupuncture points by applying suction through a metal, wood or glass jar, in which a partial vacuum has been created. This technique produces blood congestion at the site, and therefore stimulates it. Cupping is used for low backache, sprains, soft tissue injuries, and helping relieve fluid from the lungs in chronic bronchitis.
One of the most popular alternatives to Acupuncture is Acupressure. This is simply Acupuncture without needles. Stimulation of the Acupuncture points is performed with the fingers or an instrument with a hard ball shaped head. Another variation of Acupressure is Reflexology (also called Zone Therapy). This is where the soles of the feet and the posterio-inferior regions of the ankle joints are stimulated. Many diseases of the internal organs can be treated in this manner.
The question arises, how does Acupuncture work?
Scientists have no real answer to this; as you know many of the workings of the body are still a mystery. There are a few prevailing theories.
1. By some unknown process, Acupuncture raises levels of triglycerides, specific hormones, prostaglandins, white blood counts, gamma globulins, opsonins, and overall anti-body levels. This is called the "Augmentation of Immunity" Theory.
2. The "Endorphin" Theory states that Acupuncture stimulates the secretions of endorphins in the body (specifically Enkaphalins).
3. The "Neurotransmitter" Theory states that certain neurotransmitter levels (such as Seratonin and Noradrenaline) are affected by Acupuncture.
4. "Circulatory" Theory: this states that Acupuncture has the effect of constricting or dilating blood vessels. This may be caused by the body's release of Vasodilaters (such as Histamine), in response to Acupuncture.
5. One of the most popular theories is the "Gate Control" Theory. According to this theory, the perception of pain is controlled by a part of the nervous system which regulates the impulse, which will later be interpreted as pain. This part of the nervous system is called the "Gate." If the gate is hit with too many impulses, it becomes overwhelmed, and it closes. This prevents some of the impulses from getting through. The first gates to close would be the ones that are the smallest. The nerve fibers that carry the impulses of pain are rather small nerve fibers called "C" fibers. These are the gates that close during Acupuncture.
In the related "Motor Gate" Theory, some forms of paralysis can be overcome by Acupuncture. This is done by reopening a "stuck" gate, which is connected to an Anterior Horn cell. The gate, when closed by a disease, stops motor impulses from reaching muscles. This theory was first stated by Professor Jayasuriya in 1977. In it he goes on to say:
"...one of the factors contributing to motor recovery is almost certainly the activation of spindle cells. They are stimulated by Gamma motor neurons. If Acupuncture stimulates the Gamma motor neurons, the discharge causes the contraction of Intrafusal Muscle fibers. This activates the Spindle cells, in the same way as muscle stretching. This will bring about muscle contraction."
There are many diseases that can be treated successfully by Acupuncture or its related treatments. The most common ailments currently being treated are: lower backache, Cervical Spondylosis, Condylitis, Arthritic Conditions, Headaches of all kinds (including migraine), Allergic Reactions, general and specific use for Analgesia (including surgery) and relief of muscles spasms. There have also been clinical trials in the use of Acupuncture in treating anxiety disorders and depression. Likewise, very high success rates have been found in treating addictions to alcohol, tobacco (nicotine) and "hard' drugs. Acupuncture can rid the body of the physical dependency, but can not rid the mind of the habit (psychological dependency). For this reason, Acupuncture treatment of addictions has not been fully successful.
