Meta Analysis of Needling Improves Migraine Symptoms and Cerebral Blood Flow Speed

Objective To systematically evaluate the efficacy of needling to improve migraine symptoms and cerebral blood flow speed. Methods Computer retrieves PubMed, EmBase, The Cochrane Library, CNKI, WANFANG Data, CBM and VIP databases to collect needling to improve migraine symptoms and cerebral blood flow speed. By September 2017, two researchers independently screened the literature, extracted information and evaluated the risk of bias in the study, Meta analysis was conducted using the RevMan 5.3 software. The results included 17 RCTs, including 2,226 patients.Meta analysis results showed: needling group and false needling [SMD=-0.97,95% CI (-1.60, - 0.34), P=0.002] and the drug group [SMD=-1.29,95% CI (-1.85, -0.73), P=0.000 01] and the drug group [SMD=-0.73,95% CI (-1.25, -0.21), P=0.006] and the drug group [SMD=- 0.88,95% CI (-1.32, -0.45), P≈ 0.000 1], reduces headache duration compared to the acupuncture group [SMD=-0.67,95% CI (-1.15, -0.19), P=0.006] and is better than the pseudopuncture group in improving cerebral blood flow rate [D=-10.99,95 %CI (-16.62, -5.36), P=0.000 1] and drug groups [SMD=-0.63,95% CI (-0.87, -0.40), P^0.000 01]. Conclusion Current research evidence suggests that needling reduces migraine attack frequency, reduces headache duration, and reduces headache intensity while improving cerebral blood flow rate. Incorporating research quality limitations, This conclusion is subject to validation by more high-quality studies.
