The efficacy and safety of cupping therapy for treating of intractable peripheral facial paralysis: A protocol for systematic review and meta-analysis

Comparison of the efficacy of acupuncture with tuina with acupuncture-only in the treatment of peripheral facial paralysis: a network meta-analysis

At present, traditional Chinese medicine treatment is considered safe for treating peripheral facial paralysis (PFP). Acupuncture-only and acupuncture combined with tuina are widely used for this purpose. However, it is not clear whether acupuncture combined with tuina is better for treating PFP than acupuncture-only. Conventional meta-analysis and network meta-analysis were used to compare the clinical efficacies of acupuncture combined with tuina and acupuncture-only in the treatment of PFP. Randomized controlled trials (RCTs), with the subjects being patients with PFP and treatment interventions including acupuncture combined with tuina, acupuncture-only, tuina-only, placebo, single Western medicine, and steroids combined with other Western medicine were searched from both Chinese and English databases. The primary outcomes included Modified House-Brackmann (MHBN) scores and Sunnybrook Facial Grading System, whereas the secondary outcomes included cure time, Portmann scores, and physical function scale of Facial Disability Index, using conventional meta-analysis and network meta-analysis. The study included 22 RCTs with a sample size of 1814 patients. The results of conventional meta-analysis (MD = 16.12, 95%CI 13.13,19.10) and network meta-analysis (MD = 14.53, 95%CI 7.57,21.49) indicate that acupuncture combined with tuina was better than acupuncture-only in improving MHBN and shortening the cure time (MD = - 6.09, 95%CI  - 7.70, - 4.49). Acupuncture combined with tuina was the optimal therapy for improving MHBN (SUCRA was 100%) and shortening the cure time (SUCRA was 100%). The results of this meta-analysis indicate that acupuncture combined with tuina can significantly improve MHBN and shorten the cure time, compared with acupuncture-only. However, the current evidence is insufficient, and more high-quality clinical studies are needed.Registration: This study had been registered with PROSPERO (CRD42022379395).

The Facial Skin Blood Flow Change of Stroke Patients with Facial Paralysis after Peripheral Magnetic Stimulation: A Pilot Study

Background: Facial paralysis (FP) is a common symptom after stroke, which influences the quality of life and prognosis of patients. Recently, peripheral magnetic stimulation (PMS) shows potential effects on peripheral and central nervous system damage. However, the effect of PMS on FP after stroke is still unclear. Methods: In this study, we applied PMS on the facial nerve of nine stroke patients with FP. At the same time, laser speckle contrast imaging (LSCI) was used to explore the facial skin blood flow (SkBF) in 19 healthy subjects and nine stroke patients with FP before and after the PMS intervention. The whole face was divided into 14 regions to compare the SkBF in different sub-areas. Results: In baseline SkBF, we found that there were no significant differences in the SkBF between the left and right faces in the healthy subjects. However, there was a significant difference in the SkBF between the affected and unaffected faces in Region 7 (Chin area, p = 0.046). In the following five minutes after the PMS intervention (Pre_0–5 min), the SkBF increased in Region 5 (p = 0.014) and Region 7 (p = 0.046) and there was an increasing trend in Region 3 (p = 0.088) and Region 6 (p = 0.069). In the five to ten minutes after the intervention (Post_6–10 min), the SkBF increased in Region 5 (p = 0.009), Region 6 (p = 0.021) and Region 7 (p = 0.023) and there was an increasing trend in Region 3 (p = 0.080) and left and right whole face (p = 0.051). Conclusions: These pilot results indicate that PMS intervention could increase facial skin blood flow in stroke patients with FP. A further randomized controlled trial can be performed to explore its possible clinical efficacy.
