Effects of the New Lift-Thrust Operation in Laser Acupuncture Investigated by Thermal Imaging

Abstract EN

Acupuncture manipulation is one of the key factors affecting the performance of acupuncture in Traditional Chinese Medicine.

Lift-thrust and twirl-twist are two of the most commonly used manipulation methods for needle acupuncture.

We previously have developed a novel laser acupuncture model that emulates lift-thrust operation.

In this study, we intend to show the effectiveness of such a model by applying it on the Neiguan acupoint (PC6).

Stimulation was reported to be beneficial for improving cardiac output and peripheral circulation.

Therefore, we hypothesized that the stimulation of laser acupuncture may increase the temperature of the subjects’ fingertip due to increased peripheral blood flow.

A thermal imager was used to measure the temperature change of subjects’ fingertips.

Through regression analysis, it has been shown that while PC6 is stimulated, laser acupuncture with lift-thrust operation caused a more rapid, stable, and lasting temperature rise of fingertip than that without lift-thrust operation.

On the contrary, we observe no significant temperature change when a sham point nearby PC6 (a point which is not traditionally defined as the acupoint) was stimulated.

Our results suggest the emulation of manipulation methods such as the lift-thrust operation could be a potential direction for the future development of laser acupuncture.
