Electrodermal screening is widely used in the acupuncture community for point location, diagnosis and therapy. However the underlying theory that electrical skin resistance (ESR) of an area corresponding to an acupuncture point (AP) is lower than ESR of the surrounding areas is yet to be proven. The objective of this study was to evaluate and quantify the phenomenon of ESR changes at the Gallbladder 34 (GB34) Acupuncture Point (AP).
In this single-blinded study GB34 was measured bilaterally in 43 healthy volunteers. Electrical skin resistance measurements (ESRMs) were performed with a specially designed array consisting of 64 (8 x 8) electrodes on an area of 6 x 6 cm. Then the electrodes corresponding to the AP were identified and compared with those of the surrounding electrodes with Wilcoxon rank sum test. Values for p of less than 0.05 were considered statistically significant.
Eighty-one ESRMs were evaluated. ESR was significantly different from the surrounding skin area in 27 (33.3%) cases with 15 (18.5%) points showing a lower and 12 (14.1%) points showing a higher ESR.
This shows that ESR changes at APs exist in one third of the measured points, a very low rate for a postulation that forms the basis of various diagnosis and therapy systems.
皮肤电筛查在针灸领域被广泛用于穴位定位、诊断和治疗。然而，与穴位相对应区域的皮肤电阻（ESR）低于周围区域这一潜在理论尚未得到证实。本研究的目的是评估和量化胆囊经34穴（GB34）处ESR变化现象。
在这项单盲研究中，对43名健康志愿者双侧的GB34进行测量。使用一个由64个（8×8）电极组成的专门设计的阵列，在6×6厘米的区域进行皮肤电阻测量（ESRM）。然后识别与穴位对应的电极，并通过Wilcoxon秩和检验与周围电极进行比较。p值小于0.05被认为具有统计学意义。
共评估了81次ESRM。在27例（33.3%）中，ESR与周围皮肤区域有显著差异，其中15个点（18.5%）显示ESR较低，12个点（14.1%）显示ESR较高。
这表明在三分之一的测量穴位处存在ESR变化，对于作为各种诊断和治疗系统基础的一种假设而言，该比例非常低。
