Result: Before the training, there were no statistically significant differences in gross motor quotient (GMQ), fine motor quotient (FMQ) and total motor quotient (TMQ) scores, mental development index (MDI) and psychomotor development index (PDI) scores, infant-junior high school student social life ability scale (S-M) scores between the two groups (P>). After training, the GMQ, FMQ and TMQ scores of the observation group were significantly higher than those of the control group, and the differences between groups were statistically significant (P<). The MDI and PDI scores of the observation group were significantly higher than those of the control group, and the differences between groups were statistically significant (P<). The S-M score of the observation group was significantly higher than that of the control group, and t
