Abstract: Objective To observe the effects of Children's Crawling-Promotion-Training-Robot on gross motor function and cognitive function in children with spastic diplegia.Methods From January to December, 2017, 60 children with spastic diplegia were selected and randomly divided into three groups, with 20 cases in each group. All the groups received routine comprehensive rehabilitation therapy. In addition, group I received manual crawling training, group II was treated with crawler-training therapy, and group III was treated with Children's Crawling-Promotion-Training-Robot. They were treated ten minutes every day, five days a week for twelve weeks. Before and after treatment, the gross motor development, the muscle tension and cognitive function were evaluated with Gross Motor Function Measure Scale-88 (GMFM-88), modified Ashworth Scale (MAS) and developmental quotient (DQ) in Gesell Developmental Scale (GDS), respectively.Results After treatment, the overall percentage of GMFM-88 and the score of C dimension which were tightly tied to crawling and kneeling improved in all the groups (t>17.438, P<0.001), and the score was better in groups II and III than in group I (P<0.05), especially in group III (P<0.05); the score of MAS improved in all the groups (t>2.144, P<0.05), and no significant difference was found among them (F=0.199, P>0.05); the score of DQ in GDS improved in groups II and III (t>3.040, P<0.001), and the score was better in groups II and III than in group I (P<0.05), especially in group III (P<0.05).Conclusion Children's Crawling-Promotion-Training-Robot could improve the gross motor and cognitive function of children with spastic diplegia, which is better than manual crawling training and crawler-training.
