Acupuncture originated in China[citation needed] and is most commonly associated with traditional Chinese medicine (TCM).
Different types of acupuncture (Classical Chinese, Japanese, Tibetan, Vietnamese and Korean acupuncture) are practiced and taught throughout the world.
Acupuncture is a traditional form of oriental medicine which originated in China and is being practiced by therapists all over the world now. Acupuncture treatment consists of inserting very fine needles at specific points on the skin, which are located near nerve endings. The acupuncture points are located along the 12 identified channels (meridians) through which the vital energy (Qi) and blood flows in the body.
A landmark study has shown that acupuncture provides pain relief and improves function for people with osteoarthritis of the knee and serves as an effective complement to standard care. The study, the largest Phase III clinical trial of acupuncture for knee osteoarthritis, was funded by NCCAM and the National Institute of Arthritis and Musculoskeletal and Skin Diseases, both components of the National Institutes of Health.
Acupuncture is a technique of inserting and manipulating fine filiform needles into specific points on the body to relieve pain or for therapeutic purposes. The word acupuncture comes from the Latin acus, "needle", and pungere, "to prick". In Standard Mandarin, (zhen bian) (a related word, , refers to acupuncture together with moxibustion).
According to traditional Chinese medical theory, acupuncture points are situated on meridians along which qi, the vital energy, flows. There is no known anatomical or histological basis for the existence of acupuncture points or meridians. Modern acupuncture texts present them as ideas that are useful in clinical practice. According to the NIH consensus statement on acupuncture, these traditional Chinese medical concepts "are difficult to reconcile with contemporary biomedical information but continue to play an important role in the evaluation of patients and the formulation of treatment in acupuncture."
No scientific or medical evidence that acupuncture has any efficacy beyond a placebo effect. The WHO, the National Center for Complementary and Alternative Medicine (NCCAM) of the National Institutes of Health (NIH), the American Medical Association (AMA) and various government reports have studied and commented on the efficacy of acupuncture. There is general agreement that acupuncture is safe when administered by well-trained practitioners using sterile needles, and that there is little evidence supporting its effectiveness.
