Effects of Collective Language Training Combined with Transcranial Direct Current Stimulation on Development Level,Speech Function and Nerve Central Nutrition Factor Level in Children with Language Development Delay
Objective:To investigate the effects of collective language training combined with transcranial direct current stimula-tion(tDCS)on development level,speech function and nerve central nutrition factor level in children with language development delay.Methods:90 children with language retardation admitted to Chenzhou First People's Hospital from February 2021 to February 2023 were divided into a control group(n=45,conventional language training combined with tDCS)and a research group(n=45,collective language training combined with tDCS)by envelope lottery.The efficacy,development level,speech function,nerve central nutrition factor and quality of life were compared between two groups.Results:Compared with control group,the total clinical effective rate in study group was higher(P＜0.05).The scores of motor behavior,adaptive behavior,language behavior and personalsocial behavior in two groups in-creased after intervention,and those in study group were higher than control group(P＜0.05).The scores of retelling,listening comprehen-sion,oral expression,aloud reading,copying,reading,description,dictation and calculation in two groups increased after intervention,and those in study group were higher than control group(P＜0.05).The serum levels of brain-derived neurotrophic factor(BDNF),glial cell line-derived neurotrophic factor(GDNF),nerve growth factor(NGF)and neurotrophic factor-3(NT-3)in two groups after interven-tion were higher than those before intervention(P＜0.05).There was no difference in serum BDNF,NGF,GDNF and NT-3 between two groups after intervention(P＞0.05).The scores of physiological function,social function,emotional function and role function in two groups increased after intervention,and those in study group were higher than control group(P＜0.05).Conclusion:Collective language training combine with tDCS intervention in children with language development delay,which can improve speech function and neurolog-ical function,and improve their development level and quality of life.
