目的：探讨电针在经络类型、组织学类型、神经支配等不同性质穴位上的德气特点。方法：对21名健康志愿者进行ST36-GB34、CV4-CV12、ST36-ST28、PC6-PC7、ST36-CV4配对穴位电针。针刺德气时，记录个体感觉的强度、流行程度、感觉传递、电流振幅。采用卡方检验、Fischer精确检验、Wilcoxon检验和双样本配对t检验比较各配对组内的德气成分。结果：个体感觉的总体强度和流行程度依次为丰满、麻木、疼痛、刺痛、沉重、压力、钝痛、温暖和寒冷。两对穴位针刺感发生率无显著差异（p < 0.05）。然而，ST36-ST28之间的疼痛、丰满和沉重，ST36-CV4之间的丰满和麻木，以及CV4-CV12之间的丰满，在强度上存在显著差异（p < 0.05）。针刺感强于PC6-PC7和ST36（与CV4配对）的重压感。10/216次试验出现尖锐疼痛（4.63%）。感觉传递率高（77.78%），且感觉主要在一个关节上传递，不超过两个关节。总电流为2.35±0.07 mA（平均±标准误差）。感觉传递距离和电流幅值在配对穴位间无显著差异。结论：充盈、麻木和疼痛是电针最常见和最明显的感觉。感觉强度的差异可能与不同的神经支配有关。
Objectives: This study sought to explore the characteristics of de qi using electroacupuncture at acupoints with different properties in the meridian category, histological type, and nerve innervations.Methods: Electroacupuncture was performed on 21 healthy volunteers at paired acupoints of ST36-GB34, CV4-CV12, ST36-ST28, PC6-PC7, and ST36-CV4. Upon acupuncture de qi, the intensities and the prevalence of individual sensations, sensation transmission, and the amplitude of electrical current were recorded. Chi-square, Fischer's exact test, Wilcoxon test, and two-sample paired t test were used to compare the components of de qi within each paired group.Results: Overall intensities and prevalence of individual sensations are fullness, numbness, soreness, tingling, heaviness, pressure, dull pain, warmness, and coolness in decreasing order. No significant difference was found in the prevalence of needling sensations between the two paired points (p > 0.05). However, significant intensity differences (p < 0.05) were showed in soreness, fullness, and heaviness between ST36-ST28, in fullness and numbness between ST36-CV4, and in fullness between CV4-CV12. Tingling sensation was stronger than heaviness and pressure at acupoints PC6-PC7 and ST36 (as paired with CV4). Sharp pain occurred in 10/216 tests (4.63%). Sensation transmission occurred highly (77.78%) on participants, and sensations mostly propagate over one joint but no further than two joints. Overall electrical current was 2.35 +/- 0.07 mA (mean +/- standard error). No significant difference was found between paired acupoints for the distance of sensation transmission and the amplitude of electrical current.Conclusions: Fullness, numbness, and soreness were the most common and obvious sensations associated with electroacupuncture. The difference of sensation intensities may be associated with different nerve innervations.
