Objective To optimize acupuncture treatment programs for facial paralysis.Methods Sixty-three cases of facial paralysis were randomly grouped according to orthogonal design L9（3）4 table,and treated by different combined programs of 4 factors,A（acupuncture opportunity）,B（combination of points）,C（stimulating quantity）,D（electroacupuncture time） and 3 levels,and changes of the functional score of the facial nerve were observed,and the different combined programs of the 4 factors,A（acupuncture opportunity）,B（combination of point）,C（stimulating quantity）,D（electroacupuncture time） and 3 levels influencing acupuncture therapeutic effect on facial paralysis were optimized.Results B（combination of points） and D（electroacupuncture time） were obvious factors（P0.05）,among them,B（combination of points） was the most main influencing factor;among the 3 levels of B（combination of points） and D（electroacupuncture time）,B3 （alternately needling two groups of acupoints） and D3 （electroacupuncture treatment at sparse-dense wave for 30 min） were the best.Conclusion Electroacupuncture at sparse-dense wave for 30 min,alternately needling two groups of acupoints is the best program for treatment of facial paralysis.
