摘      要：BACKGROUND： The electrophysiological test was mainly achieved by the reaction of nerve fiber to electrical stimulus, usually expressed by the amplitude and latency. Blink reflex and electroneurography （ENOG） are widely applied in facial paralysis, the amplitude would step down, and the latency would prolong when the facial nerve was injured. OBJECTIVE： To compare the value of blink reflex and ENOG in the diagnosis of facial paralysis （Bell＇s palsy）. DESIGN： A controlled trial. SETTINGS： Affiliated Hospital, Chengdu University of Traditional Chinese Medicine; West China Hospital of Sichuan University; Mianyang Hospital of Traditional Chinese Medicine; Sichuan People＇s Hospital. PARTICIPANTS： The patients who had finished the tests of blink reflex （n =207） and ENOG （n =205） were selected from the Affiliated Hospital, Chengdu University of Traditional Chinese Medicine; West China Hospital of Sichuan University; Mianyang Hospital of Traditional Chinese Medicine; Sichuan People＇s Hospital from September 2001 to July 2003. After treatment for 4 weeks, the patients finished tests of blink reflex （n =207） and ENOG （n =205） were randomly divided into primary treatment group （n =68, 69）, acupuncture group （n =71, 66） and comprehensive treatment group （n =68, 70）, respectively. Approval was obtained from the ethic committee of hospital. METHODS： Patients in the primary treatment group and acupuncture group were treated with western medicine, acupuncture and moxibustion alone respectively, and those in the comprehensive treatment group were treated with acupuncture and moxibustion based on western medicine. The whole period of treatment was 4 weeks. The tests of blink reflex and ENOG were carried out using Japanese light and electricity MEB-2200 electromyogram/induced potential instrument for once before and after treatment respectively. The normal value of the latency period of wave RI was within 13 ms, and the difference was 1 - 1.2 ms between the left and right sid
