本研究旨在为中医脉诊中手指在桡动脉上的定位方法提供一个标准化定义，即定义中医寸、关、尺的位置。从普通人群中招募了共200名受试者（100名男性和100名女性，年龄18 - 40岁）。根据古代中医记载，“肘长的6%”（ELx6%）被用作确定寸长的标准方法。我们假设“高骨”（PB）的最高点是寸的下限，因此“腕远侧横纹与高骨最高点之间的距离”（DWP）被视为寸的长度。如果这一假设成立，那么我们可以根据古代中医记载的6∶6∶7的比例来定义寸、关、尺的位置。采用相对偏差分布和配对t检验来验证研究结果。DWP与ELx6%相比的相对偏差平均值接近0%（男性 = 2.1%，标准差 = 12.2%；女性 = 0.2%，标准差 = 12.6%）。配对t检验证实DWP和ELx6%的平均值之间无显著差异（P>0.05）。因此，可以合理地假设寸的长度等于DWP的长度。我们的研究结果证实寸的位置是从腕远侧横纹到高骨最高点。
This study was to provide a standardized definition of the positioning method of finger placement on the radial artery for pulse diagnosis in traditional Chinese medicine (TCM); that is, to define the locations of Cun, Guan and Chi in TCM. A total of 200 subjects (100 males and 100 females, 18-40 years of age) were recruited from the general population. According to ancient TCM records, the "6% of the elbow length" (ELx6%) is used as the standard method of establishing the length of Cun. We hypothesized that the highest point of "prominent bone" (PB) is the lower limit of Cun, so "the distance between the distal wrist crease and the highest point of the PB" (DWP) is considered the length of Cun. If this hypothesis holds, then we can define the locations of Cun, Guan and Chi by using the ratio 6:6:7 from the ancient TCM records. The distribution of relative bias and paired t-test were used to verify the findings. The mean value of relative bias of DWP compared with ELx6% was close to 0% (males=2.1%, SD=12.2%; females=0.2%, SD=12.6%). The paired t-test confirmed that there was no significant difference (P > 0.05) between the mean values of the DWP and ELx6%. Therefore, it is reasonable to assume that the length of the Cun is equal to the length of the DWP. Our findings confirm that the location of Cun is from the distal wrist crease to the highest point of PB.
