Arterial hypertension is considered a major contributor to coronary arterial disease. The purpose of the study was to investigate the effects of Hans electrical stimulation of acupuncture points on blood pressure.
Subjects with normal and elevated blood pressure were recruited and randomly assigned into control and experimental groups. Only the experimental subjects received active Hans electrical stimulation on 2 acupuncture points for 30 minutes each session, twice a week for 5 weeks.
Twenty-seven subjects (17 male) were recruited and completed the study. The average age of the subjects was 25 +/- 5 years. The youngest subject was 20 years old and the oldest was 36 years old. After using the Hans electrical stimulation on acupuncture points for 5 weeks, the systolic blood pressure decreased significantly in the experimental group with active treatment. The mean systolic blood pressure was 117.8 +/- 4.2 mm Hg before the treatment and was reduced to 110.8 +/- 5.5 mm Hg (P < .05) in the third week and to 110.1 +/- 5.8 mm Hg in the fifth week (P < .05). The mean diastolic blood pressure was 78.1 +/- 5.0 mm Hg before treatment and was reduced to 77.4 +/- 4.3 mm Hg (P > .05) in the third week and to 74.8 +/- 4.3 mm Hg (P > .05) in the fifth week, but both did not reach statistically significant levels. The systolic and diastolic blood pressures in the control group did not show statistically significant changes. The mean systolic blood pressure was 115.6 +/- 13.3 mm Hg before the treatment and was reduced to 113.0 +/- 12.6 mm Hg (P > 0.05) in the third week and to 112.2 +/- 10.3 mm Hg in the fifth week (P > .05). The mean diastolic blood pressure was 76.4 +/- 7.9 mm Hg before treatment and was reduced to 76.5 +/- 6.9 mm Hg (P > .05) in the third week and to 73.9 +/- 5.4 mm Hg (P > .05) in the fifth week.
It was concluded that Hans electrical stimulation of acupuncture points reduced systolic blood pressure but not the diastolic blood pressure in the current subject population with normal and elevated blood pressure.
动脉高血压被认为是冠状动脉疾病的主要促成因素。本研究的目的是调查穴位的韩氏电刺激对血压的影响。
招募血压正常和血压升高的受试者，并随机分为对照组和实验组。只有实验组的受试者接受了在两个穴位上的主动韩氏电刺激，每次刺激30分钟，每周两次，共5周。
招募了27名受试者（17名男性）并完成了研究。受试者的平均年龄为25±5岁。最年轻的受试者为20岁，最年长的为36岁。在穴位上使用韩氏电刺激5周后，主动治疗的实验组收缩压显著下降。治疗前平均收缩压为117.8±4.2毫米汞柱，在第三周降至110.8±5.5毫米汞柱（P<.05），在第五周降至110.1±5.8毫米汞柱（P<.05）。治疗前平均舒张压为78.1±5.0毫米汞柱，在第三周降至77.4±4.3毫米汞柱（P>.05），在第五周降至74.8±4.3毫米汞柱（P>.05），但两者均未达到统计学显著水平。对照组的收缩压和舒张压未显示出统计学显著变化。治疗前平均收缩压为115.6±13.3毫米汞柱，在第三周降至113.0±12.6毫米汞柱（P>0.05），在第五周降至112.2±10.3毫米汞柱（P>.05）。治疗前平均舒张压为76.4±7.9毫米汞柱，在第三周降至76.5±6.9毫米汞柱（P>.05），在第五周降至73.9±5.4毫米汞柱（P>.05）。
得出的结论是，在当前血压正常和血压升高的受试者群体中，穴位的韩氏电刺激降低了收缩压，但未降低舒张压。
