OBJECTIVE: To explore the correlation of facial nerve injury degree with facial contraction degree induced by electric stimulation in the treatment of Bell's palsy withelectroacupuncture, and the significance in elec tric reaction grading evaluation. METHODS:Sixty-eight cases of Bell's palsy were enrolled. The positive and negative electrodes of the acupuncture treatment apparatus were attached to the needle handles at the 3 groups of points, named Taiyang (EX-HN 5)-Yangbai(GB 14), Xiaguan (ST 7)-Quanliao (SI 18) and Heliao (LI 19)-Jiachengjiang (Extra). The disperse-dense wave was applied. According to the severity of local muscle contraction after needling, the electric reaction was divided into 4 grades, named superior, moderate, poor and no reaction. After acupuncture and electroacupuncture, the efficacy was evaluated in accordance with the different electric reaction grades. METHODS: The curative rate was 100.0% (44/44) in patients with superior electric reaction, was 100.0% (7/7) in patients with moderate electric reaction, was 18.2% (2/11) in patients with poor electric reaction and was 0 (0/6) in patients with noelectric reaction. The difference was significant statistically in comparison of 4 groups (P<0.01). The superiority correlation presented between the efficacy and electric reaction grade (P< 0.001). The higher the superiority of electric reaction grade was, the better the efficacy was. The difference in the efficacy among different electric reaction grades was significant statistically (P<0.001). And the course of treatment was the shortest for those with the high superiority of electric reaction. CONCLUSION: The reaction grade of electric stimulation is conform to the facial nerve injury grading in Bell's palsy. The contraction degree of facial mimetic muscle induced by electroacupuncture stimulation is closely correlated with severity of disease. Based on the electric reaction, the facial nerve injury severity can be understood generally and the prognosis be judged.
