Review question

ElementPlanned (methods)Found (results)
PopulationPatients with peripheral facial palsy of any cause, duration or severity (acute and recovery phases); no age, sex or setting restriction; central, congenital, tumor, trauma or iatrogenic facial palsy excludedPatients with peripheral facial palsy (n=888 participants in 10 RCTs; 60-180 per trial)
InterventionElectroacupuncture alone or combined with standard care (EA effect isolatable)Electroacupuncture combined with conventional therapy (n=10 trials)
ComparisonConventional Western pharmacologic therapy, primarily corticosteroid-based, with or without antiviral, neurotrophic or adjunctive agentsPharmacotherapy only (n=8); manual acupuncture plus the same pharmacotherapy (n=1); pharmacotherapy followed by acupuncture after day 10 (n=1); no sham electroacupuncture control (n=0)
OutcomesCure rate; total effective rate; facial nerve function (validated scales); adverse eventsCure rate (n=10); total effective rate (n=10); facial nerve function (n=3); adverse events (n=2); no extractable long-term sequelae (n=0)
Study designsRCTs published in Chinese or EnglishRCTs (n=10)
TimingEnd of the assigned treatment course; longer-term data when availableEnd of treatment: within 3 weeks (n=3), about 1 month (n=3), unclear or course-based (n=4)
