Acupuncture

Acupuncture is a traditional therapeutic practice in which specific points of the body are stimulated, most commonly by inserting thin needles through the skin. It originated in China and became an important component of traditional Chinese medicine. Contemporary acupuncture is practiced in many countries as a traditional, complementary, or integrative health practice. Modern research has examined acupuncture particularly in relation to pain and certain other symptoms, although the strength of evidence varies according to the condition and method of treatment. The World Health Organization considers acupuncture among non-medicinal traditional and complementary practices for which evidence, quality, safety, and appropriate regulation are important considerations.

History

Acupuncture developed within the broader historical traditions of Chinese medicine. Early Chinese medical texts described methods involving stimulation of particular points on the body, although the techniques, terminology, and theories associated with acupuncture changed over different historical periods.

Traditional Chinese medical theories describe health in terms that include qi, a concept commonly translated as vital energy, and pathways known as meridians. Acupuncture traditionally involves stimulating selected points according to diagnostic and therapeutic principles developed within this medical tradition.

The practice became more systematically documented in Chinese medical literature over many centuries. Acupuncture and moxibustion were commonly discussed together, with moxibustion involving the application of heat, traditionally through burning processed mugwort near or on selected points.

During the nineteenth and twentieth centuries, acupuncture spread beyond China. Its use became established in other parts of East Asia and subsequently in Europe, North America, and other regions.

Modern medical research has examined acupuncture using clinical trials, systematic reviews, physiological studies, and comparisons with sham procedures and other treatments. Research has investigated both traditional acupuncture and approaches that interpret needle stimulation through contemporary neurophysiological mechanisms.

The World Health Organization has identified acupuncture as one of the traditional and complementary practices requiring appropriate evidence, quality standards, safety measures, and regulatory frameworks when incorporated into health systems.

Overview

Acupuncture generally involves the insertion of very thin needles into selected points of the body. Depending on the particular approach, needles may be manually manipulated or may be combined with other forms of stimulation, including electrical stimulation.

Traditional acupuncture is generally based on diagnostic concepts and treatment principles associated with traditional Chinese medicine. Practitioners may select points according to the individual's symptoms and traditional diagnostic assessment.

Contemporary clinical approaches may also use anatomical and biomedical concepts when selecting treatment points. In these settings, acupuncture may be used as a complementary intervention alongside conventional medical care.

Acupuncture is commonly studied and used for pain-related conditions. Research has reported possible benefits for some forms of chronic pain, including low-back pain, neck pain, osteoarthritis-related knee pain, and certain other pain conditions. Evidence is not uniform across all conditions, and outcomes can depend on the condition, treatment protocol, comparison group, and quality of the research.

Acupuncture is also investigated for symptoms and conditions beyond pain, including nausea and some other health problems. The evidence supporting its effectiveness differs substantially among applications.

Acupuncture should not be regarded as a universal treatment for disease. The World Health Organization emphasises that traditional and complementary practices should be evaluated using appropriate scientific evidence and integrated into health systems only in ways that support safety, quality, and effective care.

Features / Functions / Principles

Acupuncture points are specific locations traditionally selected for stimulation. Traditional systems associate these points with networks or meridians through which qi is believed to circulate.

Needle stimulation is the most characteristic feature of acupuncture. Practitioners insert sterile, thin needles through the skin at selected locations. The needles may remain in position for a period of time and may be manipulated according to the treatment method.

Meridian theory is an important component of traditional Chinese acupuncture. Traditional theory describes networks of channels connecting different parts of the body. These concepts form part of the historical framework of traditional Chinese medicine and are distinct from anatomical structures recognised in modern biomedical science.

Individualised treatment is common in traditional acupuncture. Practitioners may consider symptoms, medical history, observations, and traditional diagnostic findings when selecting points and determining treatment.

Electroacupuncture combines needle insertion with a small electrical current applied through selected needles. It is used in some clinical and research settings as a modification of conventional acupuncture.

Moxibustion is a related traditional practice involving the application of heat, usually from burning moxa, to or near selected acupuncture points. It is often associated with acupuncture but represents a distinct technique.

Modern research has investigated possible physiological effects of acupuncture. Proposed mechanisms include stimulation of nerves and changes in the processing of pain signals, although the precise mechanisms responsible for observed clinical effects remain an area of research. Some clinical trials have found differences between acupuncture and no treatment, while comparisons with sham acupuncture have sometimes produced smaller differences.

Safety is an important consideration. When acupuncture is performed by appropriately trained practitioners using sterile, single-use needles and appropriate procedures, serious complications are uncommon. Improper technique can result in injuries, infection, bleeding, or other complications. The practice therefore requires appropriate training, hygiene, patient assessment, and knowledge of anatomy.

Importance / Applications

Acupuncture is used in many countries as a complementary or integrative health practice. Its most extensively studied applications include several types of acute and chronic pain.

For chronic pain, research has examined acupuncture in conditions such as low-back pain, neck pain, osteoarthritis, and certain other musculoskeletal disorders. Some evidence indicates that acupuncture can provide symptom relief for particular pain conditions, although the magnitude and clinical significance of the benefit vary.

Acupuncture has also been investigated for headache and migraine management. Research has examined whether acupuncture can reduce headache frequency or severity in selected patients.

Another area of application is symptom management. Acupuncture has been studied for nausea and vomiting and for symptoms associated with some medical treatments. The strength of evidence differs according to the specific condition and treatment setting.

Acupuncture may be incorporated into multidisciplinary care. In an integrative approach, it can be used alongside conventional medical treatment rather than replacing diagnosis, emergency treatment, surgery, or other medically necessary interventions.

The practice also has cultural and historical importance. It forms part of a long-established Chinese medical tradition and has become an internationally recognised form of traditional and complementary medicine.

Training and regulation vary between countries and jurisdictions. Some countries regulate acupuncture as a health profession, while others permit its practice under specific professional or institutional arrangements. Requirements concerning education, licensing, supervision, and scope of practice therefore depend on the applicable jurisdiction.

Scientific evaluation remains an important aspect of contemporary acupuncture research. The World Health Organization's approach to traditional and complementary medicine emphasises evidence generation, safety, quality assurance, appropriate regulation, and responsible integration into health systems.
