不同低频声波对胃经五输穴的微循环及温度的影响研究

Study on Effects of Different Low Frequency Acoustic Wave on the Microcirculation and Temperature of the Five Shu Points of the Stomach Meridian

目的：探讨体感音乐低频声波（16~160 Hz）对人体胃经微循环及温度的影响。方法：在30例健康人的胃经五输穴附近,按顺序播放低频声波,以激光多普勒血流仪分析循经穴位的微循环及温度的变化,分析不同频率声波对胃经五输穴的影响。结果：A1#与A0#、A2#声波对胃经五输穴微循环和温度的影响呈现峰值,高于其他乐音,A1#音（58.27 Hz）影响最显著（P〈0.05）,与其他穴位比较有统计学意义（P〈0.05）;其中A1#音影响内庭、陷谷、解溪微循环变化明显大于其他穴位（P〈0.01）,而其影响五输穴温度变化无统计学意义。结论：胃经五输穴对特定频率的低频声波有选择性的吸收作用。

Objective： To investigate the effects of low frequency vibroacoustic sound waves（ 16-160 Hz） on microcirculation and temperature of stomach meridian. Methods： The low frequency sound waves were played on the Five Shu Points of the stomach meridian on 30 healthy people. Then the changes of microcirculation and temperature were recorded by laser Doppler flowmetry and the effects on the points were analyzed. Results： There were different effects on the microcirculation and temperature of the stomach meridian with low different frequency acoustic waves. A1 # and A0 #、A2 # had peak value. And the most significant effect（ P 0. 05） was observed on the stomach meridian with the A1# tone（ 58. 27 Hz） and there was significant statistical difference（ P 0. 01） compared with other points. A1#＇s effect on the microcirculation of Neiting,Xiangu,Jiexi was significantly bigger then other points（ P 0. 01） and its effect on the temperature of Five Shu point had no statistical difference. Conclusion： The points of stomach meridian will selectively absorb low frequency sound waves.
