Measurement of the human body in Eastern medicine is usually carried out using special units – Cun. This is an ancient unit of length, officially its fixed length varies in different countries of the East and is about 3.33 cm. However, in medical practice, such a unit is a special measure that is different for each person. The need for such a measurement has arisen, because people have different proportions and sizes of parts of the body, therefore, their active points are located differently.

Thus, Cun in oriental medicine does not have a certain value. In centimeters, it can be expressed in various numbers, depending on the size of the person.

In order to correctly indicate the position on the skin surface of acupuncture points, you need to focus on the anatomical structures that are determined upon examination of a person. These include muscles, anatomical cavities, bones, tendons, joints, folds, and other landmarks. Ancient Oriental doctors used the so-called individual Cun to measure the surface. It is equal to the distance between the first and second interphalangeal folds of the third finger of the left hand (in men) or the right hand (in women). Individual Cun can also be easily calculated by the lateral dimensions of the fingers.

Individual Cun is used to determine acupuncture points in a particular person. This is due to the fact that body sizes are different for people, and each individual measure is different. The application of a certain value would lead to inaccuracies in determining the position of important landmarks.

At present, the so-called proportional segment is widely used to define acupuncture points.. The essence of the method is that the body is conditionally divided into several vertical parts (for example, head, abdomen, upper and lower limbs). Each of these parts, in turn, is conventionally divided into a predetermined number of segments. For example, the shoulder is conventionally divided into 9 parts. These segments are called “proportional Cun.” When describing the topography of points, it is these measures that are indicated. The figure below shows the scheme of dividing the human body into certain areas and then into proportional parts.

In addition to the longitudinal, are determined and the transverse proportional segments, helping to accurately determine the coordinates of the desired point on the surface of the body.

It should be borne in mind that the value discussed may be different in different parts of the body in one person. Therefore, a thorough anatomical measurement of the area under study is necessary. The resulting distance is divided into the required number of segments, the length of which is different, for example, on the surface of the head and on the extremities.

The proportional and individual cun are often very close in size to each other. Especially closely proportional and individual measures on the thumb coincide (the width of the thumb of the hand, taken along the line passing through the corner of the nail bed). Therefore, to determine the localization of points for acupuncture, you can use both methods, except for the head area.

In order to correctly find the length of a human body area, it is necessary to measure the patient in the desired position. The vertical size of the anterior abdominal wall should be measured while lying on the back. The back and palm side of the shoulder and forearm should be measured on the arm bent at the elbow and wrist joints, so that the elbow and axillary folds, the second fold of the wrist joint, are determined. Measurement of the length of the legs should be carried out in the patient sitting position. The legs should be bent at the knee joints and not lean on anything.

The modern manual contains tables in which the standard parts of the body are indicated, which are divided into a certain number of proportional segments.

To determine the position of the active points at first, with the help of diagrams and atlases determine the appropriate area of ​​the body. Then, using proportional Cun of the patient, specify the desired localization. Finally, carefully examining the selected area using probing, determine the direct location of the active point on the skin.
