Acupuncture has been used in the treatment of a variety of illnesses for more than 2000 years. The practice of acupuncture is based on a theoretical system different from our understanding of human anatomy and physiology, and has developed through experience and observation. Stimulation of selective acupoints (situated along 'meridians' in the body) by inserting needles is believed to restore bodily functions by promoting the flow of 'vital energy', throughout the system. Other forms of stimulation which have been developed are heat, electrical stimulation, magnetism and, recently, laser. Laser acupuncture offers distinct advantages over the traditional method because the procedure is pain-free and non-traumatic. Clinical applications include the control of pain in osteoarthritis, lumbago and migraine, and anaesthesia for certain surgical procedures, as well as other ailments of the cardiovascular, respiratory and nervous systems. The technique is easy to learn and there is no need for sophisticated instruments. Thus it is especially useful in developing countries where health resources are limited.
