低频声波对30例健康人阳陵泉穴微循环、温度及经皮氧分压的影响研究

目的探讨体感音乐低频声波（16~160 Hz）对阳陵泉穴微循环、温度及经皮氧分压的影响。方法在30例健康人的阳陵泉穴附近,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、温度及经皮氧分压的变化,统计分析实验数据。结果不同频率的低频声波对阳陵泉穴的微循环、温度、经皮氧分压有不同影响,其中D2音（73.42 Hz）对该穴位影响最显著,微循环增加量为（106.87±18.79）%,与其它组相比,高于其他组,P〈0.01,具有统计学意义;温度数值为（26.83±2.35）℃,与其他组比较,高于其他组,P〈0.01,具有统计学意义;经皮氧分压数值为（44.87±2.79）mmHg,与其他组比较,高于其他组,P〈0.01,具有统计学意义。结论特定频率声波可引起阳陵泉穴附近微循环的显著改变,诱发共振。

The study on the influence of the low frequency acoustic wave around yanglingquan on microcircu- lation,temperature and transcutaneous oxygen pressure in 30 healthy people

Objective To investigate the influence of the low-frequency acoustic （16-160Hz） so-matosensory music around Yanglingquan on microcirculation , temperature and transcutaneous oxygen pres-sure.Methods The low frequency acoustic wave was played in the vicinity ofaround Yanglingquan in 30 healthy people in order .Laser Doppler flowmetry was applied to analyze the microcirculation , temperature and transcutaneous oxygen pressure changes of the acupoint .Then the experimental data .were analyszed . Results It is demonstrated that different frequencies of the low frequency acoustic waves have different effects on microcirculation , temperature and transcutaneous oxygen pressure .Compared with the other groups, D2 （73.42Hz） frequency had the most significant influence on the acupoints , with microcircula-tion increased to 106.87 ±18.79（P〈0.01）, , temperature value increased to 26.83 ±2.35 C（P〈0.01）, and transcutaneous oxygen pressure value increased to 44.87 ±2.79 mmHg（P〈0.01）.Conclu-sion Specific frequency of sound wave could induce resonance , which can significant change the microcir-culation near Yanglingquan .
