穴位的不同组织特性对电针针感的影响

目的：评估穴位的组织特性（不同经络、组织、神经节段）对电针针感频率、强度及产生针感电流量的影响。方法：电针针刺21名健康志愿者,根据穴位不同组织特性配成5组：足三里vs阳陵泉（ST 36 vs GB 34,不同经络）、内关vs大陵（PC 6 vs PC 7,不同组织）、足三里vs水道（ST 36 vs ST 28,不同神经节段）、关元vs中脘（CV 4 vs CV 12,不同神经节段）、足三里vs关元（ST 36 vs CV 4,不同组织、经络、神经节段）。电针频率为15 Hz,电流量以受试者能忍受但不产生尖锐性疼痛为度,间断电针3次,通电时间共90 s。记录酸感、麻木、胀满、沉重、麻刺、压感...

Summary:目的：评估穴位的组织特性（不同经络、组织、神经节段）对电针针感频率、强度及产生针感电流量的影响。方法：电针针刺21名健康志愿者,根据穴位不同组织特性配成5组：足三里vs阳陵泉（ST 36 vs GB 34,不同经络）、内关vs大陵（PC 6 vs PC 7,不同组织）、足三里vs水道（ST 36 vs ST 28,不同神经节段）、关元vs中脘（CV 4 vs CV 12,不同神经节段）、足三里vs关元（ST 36 vs CV 4,不同组织、经络、神经节段）。电针频率为15 Hz,电流量以受试者能忍受但不产生尖锐性疼痛为度,间断电针3次,通电时间共90 s。记录酸感、麻木、胀满、沉重、麻刺、压感、钝痛、热感及冷感针感和产生针感的电流量,比较配对穴位间各种针感发生的频次、强度及电流量间的差异。结果：各种针感频次在配对穴位间差异均无统计学意义（均P〉0.05）,电针针刺的9种感觉中,胀满、麻木和酸感最常见和最明显,沉重、压感和麻刺次之,钝痛、热感和冷感的发生频次均较低;部分针感强度在配对穴位间存在差别,酸感、胀满、沉重感在ST 36较ST 28更强（均P〈0.05）,胀满、麻木在ST 36较CV 4更明显（均P〈0.01）,胀满在CV 4较CV 12更明显（P〈0.05）;电针针刺电流量在配对穴位间相近（均P〉0.05）。结论：在产生针感的电流量未见明显差异的状态下,电针针感次数与穴位的不同组织间未见明显相关,穴位间针感强度的差异可能与穴位位于不同神经节段相关。不同时间电针刺激同一穴位产生的各针感频次及其强度具有相对稳定性。

electroacupuncture （EA）; needling sensation; acupoint study;intensity of needling sensation
Objective To evaluate the influence of the tissue specificity of the acupoints （different meridians, tissues and nerve segments） on the frequency, intensity and current flow output in association with electroacupuncture （EA） sensations. Methods Twenty one volunteers received EA. According to the tissue specificities of acupoints, 5 acupoint pairs were selected, named Zúsānlǐ （足三里 ST 36） vs Yánglíngquán （阳陵泉 GB 34, different meridians）, Nèiguān （内关 PC 6） vs Dàlíng （大陵 PC 7, different tissues）, Zúsānlǐ （足三里 ST 36） vs Shuǐdào （水道 ST 28, different nerve segments）, Guānyuán （关元 CV 4） vs Zhōngwǎn （中脘 CV 12, different nerve segments）, and Zúsānlǐ （足三里 ST 36） vs Guānyuán （关元 CV 4, different meridians, tissues and nerve segments）. The electric frequency was 15 Hz. The electric current was under the subject’s tolerance without sharp pain induced. EA lasted 90 s with 3 discontinuities. The sensations, such as soreness, numbness, fullness/distention, heaviness, tingling, pressure, dull pain, hotness and coldness were recorded as well as the current flow output in association with the needling sensations. The differences in the frequency, intensity and current flow output relevant with the needling sensations were compared among the different acupoint pairs. Results There were no significant differences in the frequency of the needling sensations among the different acupoint pairs （all P〉0.05）. Of 9 different sensations of EA, fullness/distention, numbness and soreness presented the most commonly and remarkably; heaviness, pressure and tingling were on the second top; dull pain, hotness and coldness occurred at the lower frequency. There were the differences in the intensity of some needling sensations among the acupoint pairs, in which, the intensity of soreness, fullness/distention and heaviness was stronger at Zúsānlǐ （足三里 ST 36） vs Shuǐdào （水道 ST 28） （all P〈0.05）; the intensity of fullness / distention, and numbness was stronger at Zúsānlǐ （足三里 ST 36） vs Guānyuán （关元 CV 4） （P〈0.01）; the intensity of fullness/distention was stronger at Guānyuán （关元 CV 4） vs Zhōngwǎn （中脘 CV 12） （P〈0.05）. The current flow output of EA was similar among the acupoint pairs （all P〉0.05）. Conclusion In the situation that there is no obvious difference in the current flow output associated with EA sensations, the frequency of EA sensations does not relevant apparently with the different tissues. The difference in the intensity of the needling sensations among the different acupoints is probably relevant with the nerve segments at the acupoint locations. The frequency and the intensity of the different needling sensations at the same acupoint are relatively stable at the different times of EA.
