中文摘要 | 根據中國傳統醫學,經絡具有溝通表裡上下,聯繫臟腑器官,通行氣血,濡養臟腑組織,感應傳導及調節人體各部分之功能。本研究以系統分析著手,將穴位視為經絡系統傳遞信息的輸入端及輸出端。分別在大腸經,心包經及胃經的原穴合谷穴、大陵穴以及衝陽穴,輸入音頻white noise信號,觀察入信號經過經絡傳導後在大腸經的量測穴位點手三里、臂臑穴,心包經的內關穴、曲澤穴,以及胃經的足三里等穴位上所造成之變化。並以系統鑑識法(System identification)分析經絡系統的轉移函數(T.R.F)特性,據以了解臨床病患者當臟腑病變時所引起之經絡特性變化。同時,為了觀察經絡穴位與非穴位之差異性,本研究以大腸經為量測經絡,以手三里及臂臑穴為量測穴位點,溫溜穴外一公分之非穴位點設為對照點,量取輸出信號後比較兩者之差異性。此外,研究中亦進行大腸經上兩側迎香穴之比較。實驗中所量取之信號均以多功能分析儀(MA6000)及PC音效卡之數位信號處理功能做即時分析。 研究結果顯示,大腸經之最佳傳導頻率為32.67±3.72Hz;心包經最佳傳導頻率為32.76±4.32Hz;高血壓病患的胃經傳導頻率(28.75±4.52Hz)則較正常人略低(32.37±4.25Hz)。正常人與高血壓患者的穴位輸出信號比較也有明顯差異(p<0.05),高血壓患者經雷射針灸治療前後足三里穴位的輸出信號強度亦有差異(p<0.05)。大腸經上之穴立與非穴位點的輸出信號有明顯差異(p<0.01)。此外,輸入信號在大腸經上的合谷穴,其同經絡上的迎香穴比對側迎香穴有較高的信號輸出(p<0.01)。透過本研究在經絡高傳聲特性上的證實,提供了未來中醫臨床診斷及療效評估的重要參考。 |
英文摘要 | According to the traditional Chinese medicine, the meridian system is the pathway to transport energy in human body. In the system, all the organs benefit of a harmonious circulation of this energy in all its sectors. Numberous researchers have investigated the problem concerning the existence of meridians, but so far no definite answers have been found. The study was to analyze the characteristics of meridian system by the way of System Identification with input of white noise signals in acupuncture points Li4, P7 and ST42,a and with output signals from LI10, LI14, LI20, P6, P3, and ST36 The output signals from those selected qcupoints were analyzed with the way of System Identification for characterizing meridian system. The research also compared the output signals between acupoint and non-acupoint. All of output signals in this research were real-time processed using multifunction analyzer(MA6000) and DSP functions of PC soundcards. The results of this study showed that the best meridian transmitting frequency of normal group was 32.67±3.72Hz for LI meridian and 32.76±4.32Hz for meridian. For ST meridian, it was 28.75±4.52Hz in hypertension patient group which value was lower than 32.37±4.25Hz in normal group. The output signal level of normal group was higher than that of patient group (p<0.05), and the amplitude of output signal in ST36 between before-aculaser treatment and after-aculaser treatment showed a significant level of difference (p<0.05). It was also found that there was a significant level of difference existed (p<0.01) in the output signals between acupoint and non-acupoint. The output signal level of LI20 which in the same meridian path of input signal was higher than the other side of LI20 (p<0.001). With this research results, there will be a good potential ability for Chinese medical diagnosis and treatment evaluation in the near future. |
