Effect of Virtual Reality Training Combined with Core Muscle Groups on Motor Function and Surface Electromyographic Characteristics in Children with Spastic Cerebral Palsy
Objective To explore the effect of virtual reality(VR)training combined with core muscle groups on motor function and surface electromyographic characteristics in children with spastic cerebral palsy.Methods A total of 62 children with spastic cerebral palsy admitted to the Third People's Hospital of Henan Province and Zhengzhou Central Hospital Affiliated to Zhengzhou University from January 2022 to January 2023 were selected and divided into two groups according to the random number table method,with 31 cases in the control group and 31 cases in the study group.The control group received routine training intervention,while the study group received VR training combined with core muscle group intervention.The gross motor function of the lower limbs was evaluated using the gross motor function scale(GMFM-88)D and E regions,and the Berg balance scale(BBS).The Peabody motor development scale(PDMS-2)was used to evaluate fine motor function of the upper limbs.The motor function and surface electromyographic characteristics of the two groups were compared before and after intervention.Results After intervention,the fine motor quotient(FMQ)scores of both groups increased compared to before intervention(P＜0.05),and the study group was higher than the control group(P＜0.05).After intervention,the GMFM-88 D zone,GMFM-88 E zone,and BBS scores in both groups increased compared to before intervention(P＜0.05),and the study group was significantly higher than the control group(P＜0.05).After the intervention,the median frequency(MF)and electromyographic integral(iEMG)of both groups increased compared to before the intervention(P＜0.05),and the co-contraction rate(CR)of foot dorsiflexion in both groups decreased compared to before the intervention(P＜0.05).Moreover,the MF and iEMG in the study group were significantly higher than those in the control group(P＜0.05),and the CR in the study group was significantly lower than those in the control group(P＜0.05).Conclusion The application of VR training combined with core muscle groups in children with spastic cerebral palsy can effectively improve the gross motor function of the lower limbs and fine motor function of the upper limbs,reduce muscle tension,enhance recording,and improve the coordination of contraction between active and antagonistic muscles.
