Abstract:

Objective: To demonstrate that acupuncture has an instant effect in equilibrating the imbalanced electrical conductivity of Yuan-Source acupoints after intervention on the Luo-Connecting acupoint (one-side) of the same channel. Methods: The experiment was designed as a randomized blinded control trial, with 56 volunteers. Reactive Electrical Permeable Points (REPP – mostly Yuan points) were measured in terms of electrical conductivity. Patients with a split-meridian (difference between left and right measurement) were randomly included in the control or experimental group. After five minutes of needle insertion in a Luo acupoint, the needle was removed and REPP were re-measured twice within a five minutes interval. Results: From the 56 volunteers, 32 had a valid Split-Meridian Difference (SMD > 20 μA) and were included in the study. The results indicate that after the third measurement (15 minutes – M3), 100% of the experimental group had SMD < 20 μA and 55% was with a SMD = 0 μA. In contrast, for the control group, 92% remained with a SMD > 20 μA, at M3, when compared with the initial measurement (M1). Results obtained between the experimental and control group are significantly different (p < 0.001). Conclusions: The present exploratory work indicates that there is evidence of instant body response to acupuncture that can be detected by changes in the electro-conductivity of specific acupoints.
