2～6岁室间隔缺损患儿的运动发育特征研究OA

Objective To analyze the motor development characteristics of children aged 2 to 6 years with ventricular septal defect(VSD),and provide a theoretical basis for formulating individualized intervention programs.Methods A retrospective study was conducted,enrolling 123 children aged 2 to 6 years with VSD(VSD group).According to a case-to-control ratio of 2∶1,62 healthy children matched for gender and age were included as the control group.All children of both groups were evaluated using the Peabody developmental motor scale-second edition(PDMS-2).Raw scores were recorded,and the total motor quotient(TMQ),gross motor quotient(GMQ),and fine motor quotient(FMQ)were calculated.Standard scores for the gross motor subdomains(posture,mobility,and object manipulation)and fine motor subdomains(grasping and visual-motor integration)were also calculated.The collected data were statistically analyzed.Results The TMQ,GMQ,and FMQ were significantly lower in the VSD group than in the control group(P<0.05).Analysis of the standard scores for each gross and fine motor subdomain showed that posture,mobility,object manipulation,and visual-motor integration scores were significantly lower in the VSD group than in the control group(P<0.05),whereas no significant difference was found in grasping scores between the two groups(P>0.05).Conclusion The overall motor development of children aged 2 to 6 years with VSD is significantly poorer than that of age-matched healthy children.Early intervention can promote gross motor development through training in postural control and object manipulation,and enhance fine motor development through visual-motor integration training.
