Abstract

Objectives: Electroacupuncture (EA) is a popular treatment method and is gradually replacing traditional manual acupuncture (MA) to treat pain. However, whether EA is so popular because of its better pain relief effect than MA or because of the convenience that this method brings is still controversial. Neiguan and Hegu acupuncture points have been applied clinically and many studies have recorded pain-relieving effects on the head, face and neck area. However, studies have not recorded a change in pain threshold in the head, face and neck area when acupuncture is performed on one side of the body. Therefore, this study aims to compare the change in skin pain threshold between EA and MA at Neiguan and Hegu acupuncture points on the right side in healthy volunteers. Methods: Controlled intervention study, conducted on 30 healthy volunteers, was conducted at the Experimental Acupuncture Research Laboratory, Faculty of Traditional Medicine, Ho Chi Minh City University of Medicine and Pharmacy. Implementation period is from March 1, 2023 - April 28, 2023. Results: Both EA and MA methods increased the pain threshold in the head, face and neck area (p<005), the increase in pain threshold had no statistical difference between the two methods (p>0.05), and the unwanted effect noted was pain at the needle insertion site: 6.67% (EA), 13.33% (MA). Conclusion: EA and MA acupoints Neiguan and Hegu on the right can both increase the pain threshold in the head, face and neck area, both methods are safe.
