The Effect of Auricular Acupuncture on the Pulse Rate

이침 요법이 맥박의 변화에 미치는 영향

Objective : Auricular acupuncture is a method of treatment that involves needling the ear in order to produce relief of symptoms. This concept was first developed by P.Nogier, french doctor and referred to as somatotopic representation. Many authors have commented the fact that the vagus nerve supplies the external auditory and the concha. The aim of this randomised, single blind study was to investigate whether auricular acupuncture of the ear produced changes in the pulse rate, an indicator of vagal tone. Methods: 10 healthy man volunteers were divided into normal and epinephrine stimulation group. Then each group was divided into vagus area acupuncture and control area acupuncture group again. Epinephrine stimulation group was injected by epinephrine 0.3cc twice, first. All of them were needled in either the vagus area or control area of the ear, and pulse rate changes were measured by patient monitor over 1 hour. Results : In the epinephrine stimulation group, there was significant differences in the pulse rate change between vagus area acupuncture and control area acupuncture group. After injection of epinephrine, the basal pulse rate was increased 1.3~1.4 times in the control group. However, in the vagus area acupuncture group the basal pulse rate was increased only 1.1~1.2 times.
