Survey on change temperature of skin surface when using auricular acupuncture at the Jaw point in each side of the ear in healthy people: A cross-over study
Tóm tắt
Introduction: Auricular acupuncture (AA) is a method for diagnosing and treating physical and psychosomatic dysfunctions by stimulating a specific point in the ear. Some studies prove that the acupoints on the pinna have a corresponding relationship to areas of the body. According to several studies, acupoints on the body may influence the temperature of the corresponding region. In our study, we surveyed the change in temperature of the skin surface at the mandibular area when using AA at the Jaw point on each side of the ear in healthy people.
Methods: A cross-over study with 35 healthy volunteers was conducted in the Acupuncture Experimental Research Lab, Faculty of Traditional Medicine, University of Medicine and Pharmacy at Ho Chi Minh City from November 2021 to May 2022. Temperatures of the mandibular area before and after using auricular acupuncture were recorded.
Results: After using AA at the Jaw point on the left, the temperature of the left mandibular area was increased statistically from that before (from 34.34 ± 0.69 to 34.76 ± 0.72). After using AA at the Jaw point on the right, the temperature of the right mandibular area was increased statistically from that before (from 34.50 ± 0.86 to 34.31 ± 0.68). No side effects were observed during the study.
Conclusions: When using AA at the Jaw point on the ear, the temperature of the mandibular area on the side of using auricular acupuncture increased statistically, showing the relationship of the Jaw point on the ear with the mandibular area.
