    Abstract:
    OBJECTIVE: To observe the difference in the clinical efficacy on peripheral facial palsy between electro-acupuncture (EA) assisted with surface electromyography (sEMG) and conventional EA. METHODS: Sixty cases of peripheral facial palsy were randomized into an observation group and a control group, 30 cases in each one. EA was applied during the first 15 days of sickness in the two groups, at Xiaguan (ST 7), Jiache (ST 6), Dicang (ST 4), Yangbai (GB 14), Taiyang (EX-HN 5), Quanliao (SI 18) and Hegu (LI 4), once a day. In the observation, group, 15 days after sickness, according to the situation in sEMG, on the basis of the acupoints in the previous treatment, the corresponding acupoints were reselected for EA. In the control group, the conventional EA was kept on. The treatment was given once every two days till the 35th day of sickness. Separately, on the 5th, 15th and 35th days of sickness, according to the detection of sEMG in the patients of two groups, the means ratios of: root mean square (RMS) of musculi buccinators, orbicularis oris, frontalis and nasalis on the healthy and affected sides were recorded and analyzed. RESULTS: The differences of ratio in RMS of musculi buccinators, orbicularis oris, frontalis and nasalis on the healthy and affected sides were significant statistically in comparison between the, 15th day and the 5th day, and between the 35th day and the 15th day of sickness within each group (all P<0. 01). The differences of ratio in RMS of the muscles on the healthy and affected sides were significant statistically on the 15th and 35th days between the two groups (all P<0. 05). CONCLUSION: EA assisted with sEMG achieves the significant efficacy on peripheral facial palsy, better than the conventional EA.
