Theory
Acupoints used in treatment may or may not be in the same area of the body as the targeted symptom. The Traditional Chinese Medicine (TCM) theory for the selection of such points and their effectiveness is that they work by stimulating the meridian system to bring about relief by rebalancing yin, yang and qi (also spelled "chi" or "ki"). This theory is based on the paradigm of TCM and has no analogue in western medicine.
Body acupoints are generally located using a measurement unit, called the cun, that is calibrated according to their proportional distances from various landmark points on the body. Acupoint location usually depends on specific anatomical landmarks that can be palpated. Many of these basic points are rarely used. Some points are considered more therapeutically valuable than others, and are used very frequently for a wide array of health conditions.
Points tend to be located where nerves enter a muscle, the midpoint of the muscle, or at the enthesis where the muscle joins with the bone. Location by palpation for tenderness is also a common way of locating acupoints (see also trigger point). Points may also be located by feeling for subtle differences in temperature on the skin surface or over the skin surface, as well as changes in the tension or "stickiness" of the skin and tissue. There is no scientific proof that this method works and some practitioners disagree with the method.
Body acupoints are referred to either by their traditional name, or by the name of the meridian on which they are located, followed by a number to indicate what order the point is in on the meridian. A common point on the hand, for example, is named Hegu, and referred to as LI 4 which means that it is the fourth point on the Large Intestine meridian.
Acupuncture points often have allusive, poetic names that developed over the course of centuries, often involving synonyms to ensure similar points are located on the appropriate limb. A total of 360 points are generally recognized, but the number of points has changed over the centuries. Roughly 2/3 of the points are considered "yang", while the remaining 1/3 are considered "yin".

Famous quotes containing the word theory:
“Osteopath—One who argues that all human ills are caused by the pressure of hard bone upon soft tissue. The proof of his theory is to be found in the heads of those who believe it.”
—H.L. (Henry Lewis)
“We have our little theory on all human and divine things. Poetry, the workings of genius itself, which, in all times, with one or another meaning, has been called Inspiration, and held to be mysterious and inscrutable, is no longer without its scientific exposition. The building of the lofty rhyme is like any other masonry or bricklaying: we have theories of its rise, height, decline and fall—which latter, it would seem, is now near, among all people.”
—Thomas Carlyle (1795–1881)
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
