Abstract:ObjectiveTo explore the effects of external counterpulsation treatment combined with multifunctional suspension training on gross motor function of children with spastic cerebral palsy(CP). Methods Forty-two children with spastic cerebral palsy confirmed in rehabilitation center of Childrens Hospital of Shanghai Jiaotong University from January 2019 to January 2021 were selected as the research subjects and randomly divided into control group and observation group (n=21, each). Multifunctional suspension training was conducted three times a week (40 min/time) in control group, and external counterpulsation treatment was performed three times a week (60 min/time) based on multifunctional suspension training in observation group. In both groups, one course of treatment lasted for 3 months, with two courses of total treatment for all patients. Gross motor ability, balance function and muscle tension were evaluated by gross motor function test scale (GMFM-88), Berg balance scale(BBS) and modified Ashworth assessment (MAS) of muscle tension of lower limbs and compared between two groups.Results After 6 months of treatment, GMFM-88 and BBS significantly increased compared with those before treatment in two groups (P<0.01),and GMFM-88 score[（64.72±19.62）vs（53.22±13.79），P<0.01] and BBS [（13.38±5.71）vs（11.19±4.56），P<0.05] in observation group were statistically higher than those in control group. After treatment, the total effective rate for lower limb muscle tension in observation group was better than that in control group, but there was no statistical difference in it (90.48% vs 66.67%, P>0.05). Conclusion In the comprehensive rehabilitation for children with spastic cerebral palsy, external counterpulsation combined with multifunctional suspension training can effectively improve the gross motor ability, balance function and muscle tension.
