To investigate the change of skin impedance of acupoints along the Lung meridian in response to transcutaneous electrical nervous stimulation over an acupoint (Acu-TENS) over BL13 (Feishu).
This was a double-blinded, randomized, controlled crossover study.
SETTINGS/LOCATION: The study was conducted in a laboratory.
Eighteen (18) healthy individuals comprised the study subjects.
The intervention was a session of 45-minute Acu-TENS (application of TENS on BL13, Feishu) or placebo-TENS (similar to Acu-TENS but without electrical output).
Skin impedance at 10 acupoints on the Lung meridian was recorded before and after the 45-minute intervention period. Heart rate variability during the intervention was analyzed from continuous heart rate monitoring.
Skin impedance at all acupoints along the lung meridian decreased significantly after Acu-TENS, when compared to placebo-TENS (p<0.05). A significant reduction in sympathetic activity was also observed after Acu-TENS (p=0.012).
Acu-TENS appears to modify skin impedance of acupoints along a related meridian and possibly modulates sympathovagal balance.
探讨经皮穴位电神经刺激（Acu-TENS）对肺经穴位 BL13（肺俞）时穴位皮肤阻抗的变化。
这是一项双盲、随机、对照交叉研究。
地点/设置：研究在实验室进行。
18 名健康个体为研究对象。
干预措施为 45 分钟的 Acu-TENS（在 BL13、肺俞处施加 TENS）或安慰剂-TENS（类似于 Acu-TENS，但没有电流输出）。
在 45 分钟干预期前后，记录肺经 10 个穴位的皮肤阻抗。通过连续心率监测分析干预期间的心率变异性。
与安慰剂-TENS 相比，Acu-TENS 后所有肺经穴位的皮肤阻抗均显著降低（p<0.05）。Acu-TENS 后还观察到交感神经活动的显著降低（p=0.012）。
Acu-TENS 似乎可以调节相关经脉上穴位的皮肤阻抗，并可能调节交感神经和副交感神经的平衡。
