Brief Summary

Acupuncture is a method of inserting very thin needles into special points on the body which are called acupoints, to treat diseases. This treatment has been widely applied in health care for over 2500 years. Currently, by synthesizing the results of many clinical studies, the World Health Organization (WHO) has recognized the importance of acupuncture as an effective treatment for various diseases. However, the specific effect of acupoints is still controversial. Until now, several studies have shown that acupoints are associated with certain areas of the human body that are far from the acupoints and can alter the temperature of those area. In our study, we will survey on the change in skin surface temperature at the neck when using acupuncture at Houxi point in healthy volunteers.

Detailed Description

Participants and Methods: A randomize controlled trial will be conducted by comparing the change in the skin surface temperature before and after using acupunture at the control acupoint (Yuji - LU10) and the research acupoint (Houxi - SI3) on either the left or right hand in healthy volunteers. A total of 60 participants will be randomly assigned to 2 group (A and B) and the allocation was 1:1. Both groups will undergo two trial phases 07 days apart, corresponding to one acupoint on the same hand in each step. Group A (acupoints on the left hand): participants will be received acupuncture at the control acupoint (Yuji - LU10) in the first trial phase, and the second phase will be conducted after 07 days at the research acupoint (Houxi - SI3). Group B: proceeding similarly to group A, but the points are on the right hand. The primary outcome will be the change in skin surface temperature at the neck when using acupuncture at Houxi point on each hand. This trial will be performed as a 2-arm parallel design, randomize, controlled and single blinded.
