Detailed Description

Acupuncture manipulation with needling direction is important for the therapeutic effect based on traditional Chinese medicine theory. However, research usually focuses on the therapeutic effects on the acupoints and acupuncture time rather than on the manipulation method. This study applies a semiconductor analyzer to investigate the effects of acupuncture manipulation.

30 healthy participants were recruited in the study. This study employed an Agilent B1500A semiconductor analyzer to investigate the electric characteristics of meridians under directional supplementation and draining manipulation. We measured the electric current of meridians under different manipulation, and compared the difference between supplementation and draining manipulation in healthy individuals.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: acupuncture with manipulation group

30 participant were recruited in this study. All the participants received acupuncture at the acupoints (HT7、HT3、SI5、SI8、BL57、BL40、KI3、KI10) and were measured by an Agilent B1500A semiconductor analyzer.

The investigator perform acupuncture with supplementation manipulation first, followed by a measurement of the electrical characteristics using Agilent B1500A. The investigator remove the acupuncture and then perform acupuncture with draining manipulation, followed by measurements. After one meridian measurements were completed, the investigator removed the needle and proceeded to the next meridian to repeat the same procedure.
Procedure: Acupuncture manipulation
The investigator used directional supplementation and draining manipulation. The supplementation manipulation is defined as the angle of needle insertion to skin as 45 degrees with the needle tip in the same direction as the meridian. While the draining manipulation is defined as the angle of needle insertion at 45 degrees with the needle tip direction opposite to that of the meridian.
Other Names:
