What is Acupuncture?
Acupuncture is an ancient form of Chinese medicine involving the insertion of solid filiform acupuncture needles into the skin at specific points on the body to achieve a therapeutic effect. No drug is injected. The needles alone create the beneficial effects of acupuncture.
Acupuncture is used to encourage natural healing, improve mood and energy, reduce or relieve pain and improve function of affected areas of the body. It is safe and effective and is often successfully used as an alternative to medications or even surgery. Relief is often obtained with acupuncture when traditional medical therapy has failed.
Acupuncture needles are solid, usually stainless steel (they may also be gold or silver), and measure from 13-70 mm, although longer reusable ones up to about 150 mm in length can be purchased. The needles are very fine, flexible and rounded but sharp at the tip. They are ‘atraumatic’, meaning that they do not have a cutting edge like a hypodermic needle, which slices through tissue. Their design allows acupuncture needles to slide smoothly through tissues and makes them unlikely to cause bleeding or damage to underlying structures.
Acupuncture points (also referred to as ‘acupoints’) are places on the skin that have a lower resistance to the passage of electricity than the surrounding skin and are part of a network of points that were mapped centuries ago by the Chinese. Most are found along ‘meridians’ or ‘channels’ that are believed to be the pathways by which energy or Qi (pronounced ‘Chee’) flows through the body. Acupoints are located either by identifying anatomical landmarks or by the classical method (for example: “the point where the middle finger touches the thigh when standing at attention”).
A dull, heavy, or aching feeling often occurs when the needle is correctly placed. This is referred to as ‘de Qi’ and is considered by some traditional acupuncturists to be necessary for acupuncture to be effective. The experience of AFCI is that relief of pain can often be obtained without provoking the de Qi response. Recent fMRI studies indicate that there is a difference in the response of the brain to needling with and without the de Qi sensation1.
The needles are left in place for 15-30 minutes, and the practitioner may manipulate the needles to strengthen or reduce the flow of Qi. Lifting, twisting, and rotating are some of the needling techniques a practitioner may use.
