摘要
良導絡系統已成為近年來台灣中醫學界常用的經脈診斷輔助儀器。經絡能量檢測儀(Meridian Electroacupuncture Analysis Device; MEAD)是其中最常使用的一種。此儀器有操作簡單,測量迅速。但缺點是對基本的穩定度分析存疑,以及測量結果與中醫症狀無一致的聯結解釋。因此本實驗以橫斷式(cross-sectional)研究來進行,在嘉義大林慈濟醫院中醫科自然醫學實驗室實施,共徵召39位受測者經熟練的MEAD操作者測量24處經穴測量點,以間隔五分鐘的方式進行三次重複檢測。測量結果以自行編寫之程式利用皮耳森相關係數的再測法(Pearson correlation Coefficients, Retest Method),和走勢分析法進行分析,用以計算出在不同的受測者三次測量下儀器的穩定度。
經Pearson相關係數再測法分析的結果是左右經脈平均相關係數為0.87,而走勢分析法之平均走勢符合率為80.7%,可見MEAD之測量結果已有高度的再現性。實驗也發現測量結果會隨時間的增加而差異變大(Pearson 相關係數由第一次與第二次測量的相關度0.893降至第一次與第三次測量的相關度0.833),而在五分鐘內的測量則差異不大(第一次與第二次相關度0.893,第二次與第三次相關度0.886),所以推論儀器測量在五分鐘內相關度很高,五分鐘以上則相關度開始減低,但雖如此其前後檢驗之相關度仍是很高。由此項測試我們發現每個人的經脈性質皆有一種固定的模式(pattern)存在,若在進行治療或刺激時改變了人體經脈的模式,使其前後對照的一致性起了變動,則治療常是很顯著。在針對左右、陰陽臟腑、手足上下經脈進一步分析其一致性時,我們發現無任何差異(p>0.05),這顯示良導絡儀器測量時短時間內上述因素無明顯影響。
經由本研究發現利用MEAD測量值來作為經絡穴位的電性測量有其可靠之處,在正確操作之下,此儀器的再現性可接受。

Abstract

Ryodoraku Neurometric Patterns System has been the most common complimentary instrument for meridian diagnosis in the TCM industry in Taiwan. Meridian Electroacupuncture Analysis Device; MEAD) is the most common one. This instrument is user friendly with fast analysis result. However, the disadvantage lies in the basic stability analysis, and there is no relation between the result and TCM symptoms. Therefore, this study applies cross-sectional research, and is conducted in the natural medicine lab of DaLin Branch of Tsu-Chi General Hospital. We have recruited 39 subjects to be tested by skilled MEAD operators to measure 24 acupuncture points. The testing procedure is to measure three repetitive data with 5 minute window in between. Pearson Correlation Coefficients Retest Method and Trend Analysis are utilized to calculate the stability of three different measurements among different subjects.
Pearson Correlation Coefficients Retest Method shows the result of 0.87 in the left and right meridians, while Trend Analysis shows correlation rate of 80.7%. Both show the measurement of MEAD has high reappearance rate. Study also shows increased deviation along with increased duration (Pearson correlation coefficients decreased from 0.893 between first and second measurements to 0.886 between second and third measurements). Therefore, we presume a high correlation can be reached with 5 minutes of the measurement, and then it starts to decrease when the measurement is above 5 minutes. The correlation between previous and following tests is still high. From this study, we find out every individual’s meridian has a fixed pattern. If the pattern is changed through treatment or stimulation, and the consistency is altered, the treatment result is quite significant. When analyze the consistency of left and right, yin and yang, organs and viscera, meridians of upper and lower limbs, we found there is no difference (p>0.05) between these data. This shows no significant influence on the above mentioned factors when Ryodoraku Neurometric Patterns instruments are used for short period of time.
From this study, we found a reliable source of measuring electric resistance of acupuncture point by using MEAD. When following correct operating procedure, the re-appearance of this instrument can be accepted.
