Clinical Trial Summary

This study applies a semiconductor analyzer to investigate the effects of acupuncture manipulation.

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.

Intervention

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The electric current	Agilent B1500A is a device that can measure the electric current after acupuncture manipulation. The investigators measure the electric current after intervention of supplementation manipulation and draining manipulation respectively.	through study completion, an average of 90 minutes
Primary	The voltage	Agilent B1500A is a device that can measure the voltage after acupuncture manipulation. The investigators measure the voltage after intervention of supplementation manipulation and draining manipulation respectively.	through study completion, an average of 90 minutes
