Abstract: Objective To study the early intervention effect of Peabody Developmental Motor Scales 2 (PDMS-2) and the motor activities program in children with motor development retardation, so as to provide scientific reference for the early intervention of motor development retardation.Methods From June 2019 to June 2020, a total of 101 children diagnosed with motor development retardation who met the inclusion and exclusion criteria were selected into this study, and were divided into the intervention group (n=51) and control group (n=50) according to different training methods. Both groups received routine early intervention training. Children in the observation group received motor activities program additionally based on the evaluation results of PDMS-2. After a course of treatment, PDMS-2 was used to evaluate the motor function of children in two groups, and the PDMS-2 evaluation results before and after intervention were compared between the two groups.Results Before intervention, there were no significant differences in gross motor quotient (GMQ), fine motor quotient (FMQ) and total motor quotient (TMQ) between the intervention group and control group (P>0.05). GMQ, FMQ and TMQ of the intervention group were significantly improved after intervention(t=4.00, 3.17, 3.97, P＜0.01), which were also significantly higher than those in the control group after intervention (t=2.13, 2.04, 2.44, P<0.05). Before intervention, the proportion of children with fine or gross movement deviation was significantly different between groups (χ²=2.60, P<0.05).Which was significant difference before and after intervention in the intervention group(χ²=7.71,P<0.01), but which was not significantly different before and afterinterventionin the control group(χ²=3.73,P>0.05). Conclusion PDMS-2 and the motor activities program in the early intervention training can effectively improve the development of motor function of children with motor development retardation
