Acupuncture is rooted in a traditional history that dates back at least 3000 years. Research has demonstrated the physiological and neurobiological basis for many of the effects of acupuncture, which has made it more acceptable for many Western physicians. This past year has seen research using single-photon-emission computerised tomography and functional magnetic reasonance imaging technology to examine the effect of body acupuncture on brain physiology. Proper research methodology is important in the evaluation of any treatment modality, and acupuncture has unique considerations when it comes to blinded prospective study. The important event of the past year was the Consensus Development Conference held by the US National Institutes of Health (NIH) in November 1997. The consensus panel evaluated existing clinical research and weighed the strength of the data supporting acupuncture for the treatment of various clinical conditions. The panel, after hearing presentations from experts in various areas, concluded that there is evidence that needle acupuncture treatment is effective for postoperative and chemotherapy-associated nausea and vomiting, nausea in pregnancy, and postoperative dental pain. In addition, there are several conditions for which acupuncture may be effective as an adjunct therapy, as an acceptable alternative, or as part of a comprehensive treatment programme, although there is less convincing scientific data for this. These conditions include addiction, stroke rehabilitation, headaches, menstrual cramps, tennis elbow, fibromyalgia, low-back pain, carpal tunnel syndrome, and asthma. The data presented also suggest uses for other conditions. High-quality clinical research is needed regarding acupuncture therapy and outcomes. An unprecedented number of research grants were given this year. The NIH funded a US $1 million grant for a 3=year trial of acupuncture for knee osteoarthritis. Three additional grants of US $300 000 to US $350 000 annually for 3 years were announced recently for back pain, dental pain, and depression. In the UK, the NHS Health and Technology Assessment Research and Development Programme awarded the Research Council for Complementary Medicine a 21⁄2 year grant of £130 000 to evaluate acupuncture for the management of headaches. There are several professional acupuncture societies for physicians practising acupuncture. These include the American Academy of Medical Acupuncture, the British Medical Acupuncture Society, and the International Council of Medical Acupuncture and Related Techniques. In the USA, the AAMA represents physicians, sets out training guidelines, and has
