Effect Of Virtual Reality Combined With Walking Robot On Walking Ability Of Children With Cerebral Palsy

Objective: By comparing the changes in walking function score and muscle surface EMG index of children with cerebral palsy under different degrees of weight loss using virtual reality walking robots,the effect of using virtual reality walking robots on walking ability in children with cerebral palsy(CP).Methods: Sixty school-age children with spastic cerebral palsy were recruited and randomly divided into four groups: control group,experimental group 1,experimental group 2,and experimental group 3,with 15 in each group.The control group received conventional rehabilitation training;the experimental group was trained on the basis of conventional rehabilitation training for virtual reality walking robots,and different weight loss levels were set for different experimental groups through the suspension device.The weight loss support of experimental group 1 was 10%.Fifth,the weight loss support of experimental group 2 is 30%,and the weight loss support of experimental group 3 is 45%.The gross exercise scale(GMFM-88),sixminute walking test(6-MWT),Berg balance scale,modified Tardieu scale(MTS),and gastrocnemius surface EMG and the bone density of the calcaneus of the affected lower limb.Results:(1)There was no difference in GMFM-D / E after one month of treatment.After 12 weeks of treatment,GMFM-D / E in the experimental group was higher than that in the control group(P<0.05),and there was a significant difference in the experimental group 2(P<0.01);(2))After 12 weeks of treatment,the two-minute and six-minute walking experiments in the experimental group improved more significantly than the experimental groups 1 and 3(P<0.01);(3)According to the results of the balance scale,the experimental group showed slightly higher balance control capabilities.In the control group(P<0.05);(4)after 12 weeks of training,the degree of gastrocnemius spasm in the experimental group 2 was partially reduced compared with the control group(P<0.05);(5)the electromyographic foot of the ankle joint surface in the experimental group 2 after 12 weeks of training Back extension CR was the most significant improvement in the experimental group,and the gastrocnemius muscle strength was significantly increased(P<0.05);(6)After 12 weeks of training in the experimental group,bone mineral density BMD in the affected lower limbs of children with cerebral palsy increased compared to the control group(P<0.05).Conclusion:(1)Virtual reality combined with walking robot training can help improve the gross motor ability of children with cerebral palsy,improve the balance function,increase the burden on the affected side,establish a standardized symmetrical gait,and improve their walking ability.(2)Virtual reality combined with walking robot training promotes rhythmic movement of lower limbs in children with cerebral palsy,improves ankle coordination,enhances gastrocnemius muscle strength,and reduces ankle clonus.(3)There are significant differences in the effects of virtual reality with different weight support walking robot training on motor ability of children with cerebral palsy.When the weight loss support is 30%,the effect of training on the gross motor ability,balance ability,walking ability and reducing gastrocnemius muscle tension of children with cerebral palsy is more significant.(4)Virtual reality combined with walking robot training can enhance bone deposition in the lower limbs of children with cerebral palsy,and has no significant relationship with different degrees of weight support.
