CorrelationAnalysis of the Severity of Flexible Flat Feet with Walking Balance Stability and Joint Coordination Function in School-age Children
Objective:To analyze the correlation between the severity of school-age children's flexible flat feet and the stability of walking balance and joint coordination function.Methods:Sixty school-age children with flexible flat feet admitted to Changzhou Childrens Hospital from January to December,2023 were taken as the research object,and the children were divided into mild group(n=20),moderate group(n=20)and severe group(n=20)according to the clinical manifestations and the severity of the disease judged by the imaging examination results.At the same time,20 healthy children were included as the reference group.Three-dimensional gait analysis was carried out for four groups of children,and the analysis data were compared.Results:There was no significant difference in gait frequency between the four groups(P＞0.05).The time ratio,step speed,step length and step width of the four groups were compared,and the difference was statistically significant(P＜0.05).Among them,the time ratio and step width of supporting phase in mild group,moderate group and severe group were all larger than those in refer-ence group,and the step speed and step length were smaller than those in reference group,with statistical signifi-cance(P＜0.05).The ratio of the kinematics parameters of the left and right ankles in sagittal plane,horizontal plane and frontal plane in the four groups was statistically significant(P＜0.05).Among them,the parameters of ankle joint kinematics in sagittal plane,horizontal plane and frontal plane in mild group,moderate group and severe group were lower than those in reference group,and the difference was statistically significant(P＜0.05).At the same time,the ankle joint kinematics parameters in sagittal plane,horizontal plane and frontal plane were com-pared among mild group,moderate group and severe group,and the difference was statistically significant(P＜0.05).Conclusion:The severity of school-age children's flexible flat feet is related to the stability of walking bal-ance and joint coordination motor function.Among them,the poor joint coordination motor function of mild chil-dren is significantly more than that of moderate and severe children.
