Emulated laser-acupuncture system.

Area of Science:

• Biomedical Engineering
• Traditional Chinese Medicine
• Acupuncture Research

Background:

• Traditional acupuncture utilizes manual manipulation techniques like lifting and thrusting.
• Developing non-invasive methods to replicate these techniques is of significant interest.

Purpose of the Study:

• To develop and evaluate a novel laser-acupuncture system capable of performing lifting and thrusting manipulations.
• To compare the efficacy of laser acupuncture with and without lifting and thrusting on human meridians.

Main Methods:

• A 780 nm laser diode system was designed with adjustable focus to simulate needle depth.
• Light spot characteristics were analyzed to ensure comparability with traditional needle diameters.
• Ryodoraku values of the heart and small-intestine meridians were measured after stimulating the Shenmen point (HT7) in five subjects.

Main Results:

• The focused laser spot diameter was 0.11 mm, comparable to acupuncture needles (0.22 mm).
• Laser acupuncture incorporating lifting and thrusting significantly increased Ryodoraku values compared to stimulation without manipulation (p<0.05).

Conclusions:

• The developed laser-acupuncture system effectively simulates traditional acupuncture manipulation methods.
• Laser acupuncture with lifting and thrusting demonstrates superior efficacy in stimulating human meridians, aligning with traditional acupuncture principles.
