Minimisation of variations in locating an acupuncture point using a laser-device

Area of Science:

• Acupuncture Research
• Medical Device Technology

Background:

• Accurate acupoint identification is crucial for effective clinical acupuncture.
• Traditional acupoint location relies on anatomical landmarks and practitioner experience.
• Laser devices offer a potential visual aid for precise acupoint localization.

Purpose of the Study:

• To compare the accuracy of locating acupoint PC5 using a laser device versus the naked-eye method.
• To evaluate the impact of laser-assisted technology on acupoint localization consistency.

Main Methods:

• Twenty-two participants marked acupoint PC5 on an arm using both naked-eye and laser device methods.
• Kernel density estimation was employed to analyze the distribution of marked acupoints.

Main Results:

• The laser device method resulted in a less dispersed distribution of acupoints compared to the naked-eye method.
• Significant differences in accuracy were observed along the longitudinal axis, favoring the laser device.
• No significant differences were found in the horizontal axis between the two methods.

Conclusions:

• Laser-assisted acupoint location can decrease variability in point identification.
• The use of laser devices enhances accuracy and consistency in acupoint localization.
• Laser tools are recommended for standard practice in acupuncture research and education to improve precision.
