The clinical study of internal immobilization of three-flanged nail underacupuncture anesthesia has shown that the effects obtained by selecting acupo-ints controlled by the corresponding nerve trunk and neural segment are betterthan those obtained by selecting other acupoints

leading to a marked rise ofexcellent rate of acupuncture anesthesia. In order to investigate whether theeffects of acupuncture anesthesia yielded by selecting acupoints dominated bythe corresponding nerve trunk together with body points and ear or face pointsare superior to those. yielded by only selecting acupoints dominated by thecorresponding nerve trunk

a clinical observation has been made. In this paper
