基于正交试验设计的电针治疗周围性面瘫疗效评价

目的通过对周围性面瘫患者的临床观察,分析各因素对疗效影响的差异,优选周围性面瘫的最佳电针治疗方案,为提高针灸治疗本病的临床疗效提供科学实验依据。方法本研究共90例患者,随机分为9组,每组10例,运用正交试验设计的方法,采用针刺时机（急性期、静止期、恢复期）、电针波形（密波、疏波、疏密波）、腧穴配伍（面部＋头穴、面部＋体穴、面部＋头体穴）的三因素三水平搭配组合方案,随机分入L9（34）正交表安排的9组试验中,进行试验观察,共观察4星期。采用电生理的方法测定面神经动作电位波幅。正交分析采用直观分析及方差分析。结果采用急性期、选择电针疏密波形、取面部＋体穴针刺治疗周围性面瘫可以使面神经波幅恢复最快,且各因素对疗效影响从大到小排列为针刺时机〉电针波形〉腧穴配伍。结论 电针治疗周围性面瘫最佳方案为急性期、疏密波形、取面部＋体穴针刺。不同因素对电针治疗周围性面瘫疗效的影响不同,其中针刺时机的正确选择对疗效影响最大,其次为电针波形,再次为腧穴配伍。

Evaluation of the Efficacy of Acupuncture in Treating Peripheral Facial Paralysis Based on an Orthogonal Experimental Design

Objective By clinical observation,to compare the influences of different factors on the therapeutic effect on peripheral facial paralysis and seek the optimum electroacupuncture protocol so as to provide a scientific experimental basis for improving the clinical therapeutic effect of acupuncture on this disease.Methods A total of 90 patients were randomly allocated to nine groups,10 cases each,using an orthogonal experimental design,the three-factor(acupuncture time,electroacupuncture waveform and point com...
