人體經絡導電性與極化性的優勢方向與對稱性之研究

Preferential Direction and Symmetry of Electric Conduction and Dielectric Polarization of Human Meridians

目的：經絡具有較佳的導電度以及較佳的電磁波傳遞，前者可用電流的峰值 代表，後者可用極化度來描述。左痛刺右，右痛刺左，是常用的針灸止痛方 法。本研究之目的為檢測人體左右對稱穴位與非對稱穴位是否具有電學上的 差異，並分析其方向性。 方法：選取 62 名受測者，隨機分成兩組，A 組 30 位（14 名男性和 16 名女 性），平均年齡為 28.6±9.7。B 組 32 位（男性 15 名女性 17 名），平均年 齡為 26.9±8.6。1.5V 直流電壓由個人電腦調控輸出，量測儀器與電腦連線， 通路 14 秒內擷取 640 個電壓值讀數直接輸入電腦轉換為電流，擷取電流峰 值（導電度）與計算百分比落差（極化度）；對稱組有左右外關穴與左右大 陵穴，非對稱組為左天井穴右外關穴、左大陵穴右孔最穴、右大陵穴左孔最 穴，統計方法為 Paired t Test 以及 One-way repeat measure ANOVA test。 結果：電流從右手臂流向左手臂，較從左手臂流向右手臂具有更高的導電度 和更低的極化度，與非對稱穴位相比，雙側對稱的穴位具有更高的導電度和 更低的極化度，皆具有統計顯著差異。 結論：形態對稱的人體其電學特性是不對稱的，並且雙側對稱的穴位比不對 稱的穴位具有更好的導電度和更差的極化度，前者意味著雙側對稱穴位具有 更好的信息連接，後者意味著他們之間具有更快的電磁波傳遞。

Objectives: Studies have shown that meridians have better conductivity and higher propagate of electromagnetic wave. The conductivity can be represented by the peak value of current, and the propagate of electromagnetic wave can be described by polarization. Bilaterally opposite, symmetric acupunctures along the meridians or branching meridians are two analgesic methods commonly used in acupuncture. The purpose of this study was to detect whether there was an electrical difference between the bilateral symmetric acupoints and the asymmetric acupoints, and to analyze the directionality of current. Methods: 62 subjects were included in this study and then randomly divided into two groups. Group A have 30 subjects (14 males and 16 females) with an average age of 28.6±9.7 and 32 subjects were in group B (15 males and 17 females) with an average age of 26.9±8.6. 1.5V DC voltage is regulated by personal computer, measuring instrument and computer connection, access in 14 seconds, 640 voltage readings are directly input the computer to convert into current, and the current peak (conductivity) is calculated and the percentage change of difference (polarization) is calculated. The symmetry groups were Wai-Kuan (left and right) and Ta-Ling (left and right). The asymmetric group is the left Tien-Ching and the right Wai-Kuan, the left Ta-Ling and the right Kung-Tsui, and the right Ta-Ling and the left Kung-Tsui. The data were analyzed by paired-t test and ANOVA test. Results: The current flows from the right arm to the left arm with a higher electric conduction and lower dielectric polarization than left to right. Bilaterally symmetric pairs of acupoints have higher electric conduction and lower dielectric polarization than the asymmetric ones. Statistics showed all the significant difference. Conclusions: These results show that a morphologically symmetric human body is asymmetrical in its conduction and polarization, and bilaterally symmetric acupoints have a better conduction and worse polarization than the asymmetric ones. The better conduction between two points means that they have a better information connection and the worse polarization between two points means that they have electromagnetic wave propagation quickly.
