Effects of electroacupuncture therapy on intractable facial paralysis: A systematic review and meta-analysis

Abstract

Objective This systematic review and meta-analysis aimed to assessment effects of electroacupuncture (EA) therapy on intractable facial paralysis. Methods The articles of EA treatment for intractable facial paralysis were retrieved from seven databases, the publication period was from its inception to November 30, 2022. Primary measure was the total effective rate, and other measures included the cure rate, Portmann scores, House-Brackmann scores, Sunnybrook scores and adverse events. The effect size of meta-analysis was expressed using relative risk (RR) or standardized mean difference (SMD) with 95% confidence interval (CI). Results A total of 18 studies with 1,119 participants were included, all of them had various aspects of bias risk. Meta-analysis results revealed that EA ways improved total effective rate more effectively compared with non-EA counterparts (RR 1.23, 95% CI 1.17–1.31, I2 = 0%, 18 studies, 1119 participants), and improved cure rate more significantly than non-EA groups (RR 2.04, 95% CI 1.70–2.44, I2 = 0%, 18 studies, 1119 participants). None of studies reported adverse events. Conclusion EA therapy is more beneficial for patients with intractable facial paralysis than non-EA, but we lack sufficient evidence to evaluate its safety and follow-up effect. Therefore, more clinical trials with high quality methodologies are needed to further verify long-term effects of EA for IFP and improve the level of evidence.

Effect of electroacupuncture combined with rehabilitation techniques on shoulder function in patients with rotator cuff injuries

“…Acupuncture at these points can provide sustained and beneficial stimulation to the muscles and nerves surrounding the shoulder joint to promote local microvascular dilation, accelerate blood flow, and aid in the absorption and metabolism of inflammatory exudates, ultimately helping to reduce inflammation and tissue adhesion around the shoulder joint[ 23 ]. Microcurrent stimulation has a feedback effect on the central nervous system, releasing endogenous opioid peptides and producing a wide range of analgesic effects[ 24 - 26 ].…”
