Objectives: To compare bone proportional cun and finger-breadth cun in the head area to clearly distinguish the anterior hairline. Methods: In this study, the head area was measured for 50 adult males and females in their 20s with normal hair condition. We compared bone proportional cun and finger-breadth cun in the head area and calculated the error by analyzing the difference between the actual location of the anterior hairline and the location measured with the two methods. Results: There was a significant difference between bone proportional cun and finger-breadth cun in the head area. The two methods showed significant difference from the actual location of the anterior hairline. In addition, as a result of calculating the error between the actual location of the anterior hairline and the location measured by the two methods, the finger-breadth cun had fewer errors than the bone proportional cun. Conclusions: The finger-breadth cun is better than the bone proportional cun as an alternative when it is difficult to find the anterior hairline.

Objectives : The bone proportional cun and body cun have been used widely for the location of acupoints in oriental medical clinic. The aim of this study is to compare the two location methods. Methods : 21 students were examined for the location of 6 acupoints (each 2 points in the 3 parts of upper limb, abdomen, and lower limb) using the twe methods. The data of location were analyzed with t-test. Results : In the upper limb, the data from bone proportional cun and body cun were proved to be different significantly. However, there was no significant difference between the data from the two methods in the abdomen and lower limb. Conclusion : The results of this study demonstrate that the oriental medical doctors should be more careful in the choice of appropriate method for the location of acupoints in the upper limb, while it is not important whether they use bone proportional cun and body cun in the abdomen and lower limb.

Objectives : The purpose of this study was to establish an accurate and effective method of locating acupoints of the forearm by studying bone proportional measurement. Methods : A total of 60 volunteers, 30 men and 30 women, participated in this study. 7 parts of the body were measured by a soft ruler or digital vernier calipers. The cun of the upper limb was calculated and analyzed. And the results were compared with the standard cun. Results : The bone proportional cun of the forearm based on height and femur was close to 11. It was different from the standard 12.5, 12 or 10. The cun of the forearm by thumb or finger width measurement was different from the standard too. Conclusions : We suggest that locating acupoints of the forearm needs to be done based on 11 cun. The confusion on locating acupoints of the forearm will be reduced by reflecting the result of the actual measurement.

Background: The purpose of this study was to redefine the location of acupoints in the lower abdomen by taking actual thoracic and abdominal measurements. Methods: Measurements of the length and height of the thorax, and both the upper and lower abdominal area were compared to standard values defined by the World Health Organization Western Pacific Region (WHO/WPRO), and medical text books such as Miraculous Pivot, and A-B Classic of Acupuncture and Moxibustion. These measurements were used to redefine the standard of 1 cun, and the cun value of the lower abdomen. Results: Of the 60 studies screened, all studies used the cun measurement system. Considerable variation in the localization of acupoints in the lower abdominal area were detected. The average measurement of a typical male lower abdomen was within 6.33 cun to 6.34 cun. From this data, 6.5 cun appears to be more accurate than the current standardized length of 5 cun. The standardized index values of the width of the 4 fingers, and the distance from the lateral prominence from the greater trochanter to the popliteal crease (Fm), appeared to apply to only males, as defined by the WHO/WPRO. Conclusion: Further studies on standardizing the index measurements for the lower abdominal area are necessary. For males, the more accurate standardized length of the lower abdomen was 6.5 cun, whereas for females, the measurement would typically be longer than 6.5 cun.

Objectives : Acupoint LU6 (Gongchoe) is known as an acupoint for the treatment of pain and bleeding caused by hemorrhoids. The purpose of this study was to critically review acupoint LU6 for treating hemorrhoids. Methods : We searched both ancient and modern literature of acupuncture and moxibustion using keywords "Gongchoe" and "hemorrhoids". We further performed an online ancient literature search for crosscheck. The searched literature was stratified by country (Korea, China, and Japan), and data were organized chronologically. Concerning literature related to hemorrhoids, data based on acupuncture treatment were compiled. Results : The bone proportional measurement of the forearm had been 12.5 cun until the Qing Dynasty but was recorded as 10 cun in "Shinkyushinzui," and the majority of modern Japanese and Korean literature indicated it as 10 cun. Gongchoe for treating hemorrhoids has been reported in the literature, including "Shinkyushinzui" (Japan, 1941), "Shiyoungzongguozhenjiujingxuexue" (Taiwan, 1963), "Gyeonghyeolhak" (Korea, 1971), and "Jinzhenmeihuashichao" (China, late Qing dynasty), but except "Jinzhenmeihuashichao", the location is different from the World Health Organization (WHO) standard acupoint location as it is 7 cun from the wrist out of 10 cun of the forearm bone proportional measurement. In addition, classical guides published until the Qing Dynasty did not report acupoint LU6 for the treatment of hemorrhoids. Conclusions : It is necessary to distinguish between Gongchoe in "Shinkyushinzui" and LU6 in WHO standard acupuncture point locations. Gongchoe (LU6)'s primary treatment for hemorrhoids has not been described in the classical literature, and further clinical evidence is needed to support it. When using Gongchoe for hemorrhoids, we should consider that the location of Gongchoe is closer to the LU5 than the standard acupuncture point locations and it is meaningful not only for treatment but also for diagnosis.
