Objective  To examine the efficacy of acupuncture in hastening recovery and reducing long-term morbidity from Bell’s palsy.
Methods  We searched the Cochrane Neuromuscular Disease Group Register Group (Till Feb. 2002), MEDLINE (Jan. 1966 to Dec. 2002); EMBASE (Jan. 1980 to Dec. 2002), LILACS (Jan. 1982 to Dec. 2002) and Chinese Biomedical Retrieval System (Jan. 1978 to Dec. 2002). We also searched grey literature. We identified all randomised or quasi-randomised controlled trials involving acupuncture in the treatment of Bell’s palsy, selected the trials ment the inclusion criteria, assessed the methodological quality, extracted data on trials’ patients, interventions, outcome measurements and results and undertook analysis.
Results  Three small randomised controlled trials were included but due to some flaws in study designs or reporting and clinical differences between trials, data from trials were not combined in a meta-analysis,and a descriptive analysis was performed.The result indicated a positive effect of acupuncture (all P lt;0.01).
Conclusions  Three small studies in this review suggested a beneficial effect but the poor quality of the trials precludes us from drawing firm conclusions. There is a need for high quality randomized controlled trials (RCTs) using a study design which assures high internal validity.
