Acupuncture in the Treatment of Abnormal Muscle Tone in Children with Cerebral Palsy: A Meta-Analysis.

Objective: To analyse the clinical efficacy of acupuncture and routine treatment in improving dystonia in children with cerebral palsy. Method: The randomized controlled trials published from the establishment of the databases to August 2022 on acupuncture in the treatment of dystonia in children with cerebral palsy were collected and comprehensively searched in China national knowledge infrastructure (CNKI), weipu (VIP), Wanfang, SinoMed, PubMed, Excerpta medica database (EMBASE), and Cochrane Library. The literature was selected according to the established standards, the quality of the included studies was evaluated, the heterogeneity of the included studies was evaluated with the I2 test, and the appropriate model was selected for analysis. Sensitivity analysis was used to evaluate the reliability of the results, and a funnel plot was used to evaluate the publication bias. Results: Fifteen studies were included in the meta-analysis. The control group was treated with routine treatment and acupuncture combined with routine treatment. The outcome index showed that the effect in the treatment group was better: Modified Ashworth Scale score: -0.52, 95% confidence interval (CI) (-0.62 to -0.41), p < 0.01. The treatment group showed reduced muscle tension to a greater extent (integral eletromyographic (iEMG) score: standard mean square deviation = -2.97, 95% CI (-4.87 to -1.06), p < 0.01). The effective rate in the control group was 74.2% and that in the treatment group was 91.5%, odds ratio = 3.70, 95% CI (2.02-6.78), p < 0.01. The funnel plot showed publication bias. Conclusion: Acupuncture combined with routine training could improve muscle tension abnormalities and improve the efficiency of clinical treatment.

Scalp acupuncture Yikang therapy on Baihui (GV20), Sishencong (EX-HN1), Zhisanzhen, Niesanzhen improves neurobehavior in young rats with cerebral palsy through Notch signaling pathway.

OBJECTIVE: To investigate the efficacy of scalp acupuncture Yikang therapy on Baihui (GV20), Sishencong (EX-HN1), Zhisanzhen, Niesanzhen, on neurobehavior in young rats with cerebral palsy based on Notch signaling pathway. METHODS: Thirty 7-day-old rats were randomly divided into sham, model and acupuncture, 10 rats in each group. The cerebral palsy model was established by the accepted modeling method, the acupuncture group selected "Baihui (GV20)", "Sishencong (EX-HN1)", "Zhisanzhen" and "Niesanzhen" for intervention 24 h after the model was made. The body masses were recorded before and after the treatment, respectively. After the intervention, the rats were subjected to suspension experiment, slope experiment, tactile stimulation experiment and Morris water maze experiment. After the end of the experiment, the morphological changes of hippocampal histology were observed by hematoxylin-eosin (HE) staining under light microscope, and the expression of Notch1, Notch3 and Hes5 were detected by Western blot and quantitative real-time polymerase chain reaction (PCR). RESULTS: The changes in body mass of the rats in each group were different; in behavioral experiments, compared with the sham, the suspension time of the model was shortened, the slope experiment, tactile stimulation experiment, and escape latency time were prolonged, and the number of platform crossing was reduced in the model, compared with the model, the suspension time of the acupuncture was prolonged, the slope experiment, tactile stimulation experiment, and escape latency time were shortened, and the number of platform crossing times was increased; HE staining showed severe hippocampal damage in the model and reduced hippocampal damage in the acupuncture. Western Blot and real-time fluorescence quantitative PCR showed that the expression of Notch1, Notch3 and Hes5 were increased in the model and the expression of Notch1, Notch3, Hes5 in acupuncture were decreased. CONCLUSIONS: Scalp acupuncture Yikang therapy may improve neurobehavior and reduce brain injury in rats with cerebral palsy by downregulating the expression of Notch1, Notch3, and Hes5.
