Abstract:

Objective To explore the application effect of collective language training in children with language development delay and its influence on developmental level，language ability and neurotrophic factor level. Methods A total of 89 children with language development delay admitted to our department from September 2019 to March 2021 were selected as the research subjects，who were randomly divided into the control group(44 cases) and the observation group(45 cases).Both groups were given transcranial magnetic stimulation therapy，the control group was given one-on-one language rehabilitation training，and the observation group was given collective language training for treatment.The development level，language ability and neurotrophic factor levels of the two groups were compared.Results Before intervention，there were no significant differences in developmental level，language ability or neurotrophic factor levels between the two groups(P>0.05).After intervention，the scores in adaptability，language，personal social interaction，language understanding，language expression and operation ability in the observation group were higher than those in the control group，and the differences were statistically significant(P<0.05).There was no significant difference in neurotrophic factors between the two groups after intervention(P>0.05).Conclusion Collective language training can significantly improve the developmental level and language ability of children with language development delay，but has no obvious effect on the level of neurotrophic factors in the brain.
