The energy flow at acupuncture point is important for understanding the mechanism of acupuncture treatment. However, there are few studies on energy at acupuncture point, and related studies have limitation in explaining the energy flow in all meridians. Thus, we aimed to understand the properties of electrical energy at acupuncture point in twelve meridians by measuring the biopotential at acupuncture and non-acupuncture points.
For each meridian, twenty subjects were participated, and biopotential was measured at five transport points and their adjacent non-acupuncture points. In each subject, both 'non-stimulation' and 'stimulation' experiments were conducted in random order. The data were analyzed in two parts: biopotential variability and biopotential difference between acupuncture and non-acupuncture points.
The biopotential variability at acupuncture point was increased by acupuncture stimulation, and it was related to the activation of Qi flow by acupuncture stimulation. The biopotential difference between acupuncture and non-acupuncture points was formed in the direction related to the Qi flow theory, and this biopotential difference tended to decrease by acupuncture stimulation.
The study on biopotential can provide a foundation for research on energy flow mechanism of acupuncture stimulation, and it is expected to overcome limitation of qualitative explanation in traditional medicine.
穴位处的能量流动对于理解针刺治疗机制很重要。然而，关于穴位能量的研究较少，且相关研究在解释所有经络中的能量流动方面存在局限性。因此，我们旨在通过测量穴位和非穴位处的生物电位来了解十二经脉中穴位处电能的特性。
每条经络选取20名受试者，在五个输穴及其相邻的非穴位处测量生物电位。对每个受试者，随机顺序进行“非刺激”和“刺激”实验。数据分两部分分析：生物电位变异性以及穴位与非穴位之间的生物电位差异。
针刺刺激会增加穴位处的生物电位变异性，这与针刺刺激激活气流有关。穴位与非穴位之间的生物电位差异沿与气流理论相关的方向形成，且这种生物电位差异倾向于因针刺刺激而减小。
生物电位研究可为针刺刺激能量流动机制的研究提供基础，有望克服传统医学定性解释的局限性。
