Objective To understand the development of intellectual structure in children with functional articulation disorder(FAD)and to research the basis for their Comprehensive rehabilitation of cognitive function. Methods A total of 30 children with FAD diagnosed in Dalian Children's Hospital and 30 normal children were tested by the Peabody picture vocabulary testl(PPVT) and the Neuropsychological Development Scale for 0-6-year-old children in the first half of 2017.To compare the children's language IQ and developmental quotient (DQ), their abilities of gross & fine movement, their language level, their adaptability and social communication with each other. Results The development of fine movement & language and adaptability of children with FAD were much inferior to normal children (t=5.241,4.100,3.256,P<0.05). The development of gross movement and social communication in FAD group were in accordance with the normal control(t=1.594,2.058,P>0.05).In the comparison of five abilities , the development of fine movement and adaptive ability of children with FAD were also lagging behind the gross movement and social communication of their own. The above differences were statistically significant (t=-2.847,-2.794,-4.268,-2.398,P<0.05) . Conclusions The intellectual structure of children with FAD may have developmental imbalance. It is necessary to assess their development level as early as possible in order to help their overall recovery.
