Treatment by manual acupuncture needling affects the vascular wall tone, and hemodynamic parameters for arterial stiffness may be characterized by treatment at the traditional acupuncture point (acupoint) of Baihui (GV20).
The acute effects of acupuncture treatment on arterial stiffness and wave reflection were investigated and, simultaneously, an augmentation index (AI), as an index of wave reflection, was estimated. These parameters were measured in male volunteers using applanation tonometry during 20 minutes of acupuncture treatment and 40 minutes post-acupuncture.
During treatment, diastolic blood pressure (BP), but not systolic BP, increased significantly. Heart rates (HR) initially tended to increase and then decrease. The AI from radial arteries increased significantly, while central aortic blood pressure (CBP) was unaffected. Post-acupuncture, the effects lasted for 30-40 minutes. The average BP and HR were +10.1+/-0.3% and -7.2+/-0.2%, respectively, and the CBPs were not altered, but the AI decreased markedly; this latter effect presumably resulted from the involvement of neurovascular modulators.
These results indicated that acute treatment at Baihui enhanced arteriosclerotic parameters. In post-acupuncture, the AI profoundly decreased, presumably resulting from the involvement with neurovascular modulators.
手动针刺治疗会影响血管壁张力，动脉僵硬度的血流动力学参数可能可通过百会穴（GV20）的传统针刺治疗来表征。
研究针刺治疗对动脉僵硬度和波反射的急性影响，同时评估作为波反射指标的增强指数（AI）。在男性志愿者接受20分钟针刺治疗期间及针刺后40分钟，使用压平式眼压计测量这些参数。
治疗期间，舒张压（BP）显著升高，而收缩压未升高。心率（HR）起初有升高趋势，随后下降。桡动脉的AI显著升高，而中心主动脉血压（CBP）未受影响。针刺后，这些效应持续30 - 40分钟。平均血压和心率分别为+10.1±0.3%和 - 7.2±0.2%，CBP未改变，但AI显著降低；后一种效应可能是由于神经血管调节因子的参与。
这些结果表明，百会穴的急性治疗增强了动脉硬化参数。针刺后，AI显著降低，可能是由于神经血管调节因子的参与。
