According to the American Academy of Acupuncture, Acupuncture stimulates the central nervous system, which consists of the brain and spinal cord to secrete certain chemicals that are sent to the brain, spinal cord, and muscles The chemical induces the release of hormones that weaken the level of pain or enhance the body’s self-regulating functions. So this change can strengthen the body’s self-healing.

Acupuncture is a form of alternative medicine. It is used most commonly for pain relief, though it is also used to treat a wide range of conditions. Acupuncture is generally only used in combination with other forms of treatment. For example, American Society of Anesthesiologists states it may be considered in the treatment for nonspecific, noninflammatory low back pain only in conjunction with conventional therapy.

Acupuncture is the insertion of thin needles into the skin. According to the search, a typical session entails lying still while approximately five to twenty needles are inserted; for the majority of cases, the needles will be left in place for ten to twenty minutes. It can be associated with the application of heat, pressure, or laser light. Classically, acupuncture is individualized and based on philosophy and intuition, and not on scientific research. There is also a non-invasive therapy developed in early 20th century Japan using an elaborate set of “needles” for the treatment of children (shōnishin or shōnihari).

Clinical practice varies depending on the country. A comparison of the average number of patients treated per hour found significant differences between China and the United States . Chinese herbs are often used. There is a diverse range of acupuncture approaches, involving different philosophies. Although various different techniques of acupuncture practice have emerged, the method used in traditional Chinese medicine (TCM) seems to be the most widely adopted in the US. Traditional acupuncture involves needle insertion, moxibustion, and cupping therapy, and may be accompanied by other procedures such as feeling the pulse and other parts of the body and examining the tongue. Traditional acupuncture involves the belief that a “life force” (qi) circulates within the body in lines called meridians. The main methods practiced in the UK are TCM and Western medical acupuncture. The term Western medical acupuncture is used to indicate an adaptation of TCM-based acupuncture which focuses less on TCM. The Western medical acupuncture approach involves using acupuncture after a medical diagnosis. Limited research has compared the contrasting acupuncture systems used in various countries for determining different acupuncture points and thus there is no defined standard for acupuncture points.

In traditional acupuncture, the acupuncturist decides which points to treat by observing and questioning the patient to make a diagnosis according to the tradition used. In TCM, the four diagnostic methods are: inspection, auscultation and olfaction, inquiring, and palpation. Inspection focuses on the face and particularly on the tongue, including analysis of the tongue size, shape, tension, color and coating, and the absence or presence of teeth marks around the edge. Auscultation and olfaction involve listening for particular sounds such as wheezing, and observing body odor. Inquiring involves focusing on the “seven inquiries”: chills and fever; perspiration; appetite, thirst and taste; defecation and urination; pain; sleep; and menses and leukorrhea. Palpation is focusing on feeling the body for tender “A-shi” points and feeling the pulse.

The most common mechanism of stimulation of acupuncture points employs penetration of the skin by thin metal needles, which are manipulated manually or the needle may be further stimulated by electrical stimulation (electroacupuncture). Acupuncture needles are typically made of stainless steel, making them flexible and preventing them from rusting or breaking. Needles are usually disposed of after each use to prevent contamination. Reusable needles when used should be sterilized between applications. Needles vary in length between 13 to 130 millimetres (0.51 to 5.12 in), with shorter needles used near the face and eyes, and longer needles in areas with thicker tissues; needle diameters vary from 0.16 mm (0.006 in) to 0.46 mm (0.018 in), with thicker needles used on more robust patients. Thinner needles may be flexible and require tubes for insertion. The tip of the needle should not be made too sharp to prevent breakage, although blunt needles cause more pain.

Apart from the usual filiform needle, other needle types include three-edged needles and the Nine Ancient Needles. Japanese acupuncturists use extremely thin needles that are used superficially, sometimes without penetrating the skin, and surrounded by a guide tube (a 17th-century invention adopted in China and the West). Korean acupuncture uses copper needles and has a greater focus on the hand.

A 2014 systematic review suggests that the nocebo effect of acupuncture is clinically relevant and that the rate of adverse events may be a gauge of the nocebo effect. A 2012 meta-analysis conducted by the Acupuncture Trialists’ Collaboration found “relatively modest” efficacy of acupuncture (in comparison to sham) for the treatment of four different types of chronic pain (back and neck pain, knee osteoarthritis, chronic headache, and shoulder pain) and on that basis concluded that it “is more than a placebo” and a reasonable referral option. Commenting on this meta-analysis, both Edzard Ernst and David Colquhoun said the results were of negligible clinical significance. Edzard Ernst later stated that “I fear that, once we manage to eliminate this bias [that operators are not blind] … we might find that the effects of acupuncture exclusively are a placebo response.” In 2017, the same research group updated their previous meta-analysis and again found acupuncture to be superior to sham acupuncture for non-specific musculoskeletal pain, osteoarthritis, chronic headache, and shoulder pain. They also found that the effects of acupuncture decreased by about 15% after one year.

Types of acupuncture

Electroacupuncture is a form of acupuncture in which acupuncture needles are attached to a device that generates continuous electric pulses (this has been described as “essentially transdermal electrical nerve stimulation [TENS] masquerading as acupuncture”).

Fire needle acupuncture also known as fire needling is a technique which involves quickly inserting a flame-heated needle into areas on the body.

Auriculotherapy, commonly known as ear acupuncture, auricular acupuncture, or auriculoacupuncture, is considered to date back to ancient China. It involves inserting needles to stimulate points on the outer ear. The modern approach was developed in France during the early 1950s.

Scalp acupuncture, developed in Japan, is based on reflexological considerations regarding the scalp.

Hand acupuncture, developed in Korea, centers around assumed reflex zones of the hand. Medical acupuncture attempts to integrate reflexological concepts, the trigger point model, and anatomical insights (such as dermatome distribution) into acupuncture practice, and emphasizes a more formulaic approach to acupuncture point location.

The skin is sterilized and needles are inserted, frequently with a plastic guide tube. Needles may be manipulated in various ways, including spinning, flicking, or moving up and down relative to the skin. Since most pain is felt in the superficial layers of the skin, a quick insertion of the needle is recommended. Often the needles are stimulated by hand in order to cause a dull, localized, aching sensation that is called de qi, as well as “needle grasp,” a tugging feeling felt by the acupuncturist and generated by a mechanical interaction between the needle and skin. Acupuncture can be painful. The skill level of the acupuncturist may influence how painful the needle insertion is, and a sufficiently skilled practitioner may be able to insert the needles without causing any pain.

Acupressure, a non-invasive form of bodywork, uses physical pressure applied to acupressure points by the hand or elbow, or with various devices.

Acupuncture is often accompanied by moxibustion, the burning of cone-shaped preparations of moxa (made from dried mugwort) on or near the skin, often but not always near or on an acupuncture point. Traditionally, acupuncture was used to treat acute conditions while moxibustion was used for chronic diseases. Moxibustion could be direct (the cone was placed directly on the skin and allowed to burn the skin, producing a blister and eventually a scar), or indirect (either a cone of moxa was placed on a slice of garlic, ginger or other vegetable, or a cylinder of moxa was held above the skin, close enough to either warm or burn it).

Cupping therapy is an ancient Chinese form of alternative medicine in which a local suction is created on the skin; practitioners believe this mobilizes blood flow in order to promote healing.

Tui na is a TCM method of attempting to stimulate the flow of qi by various bare-handed techniques that do not involve needles.
