Objective To investigate the synergistic effects of whole-body vibration training combined with MOTOmed virtual scenario training on lower limb function and gait balance in children with spastic cerebral palsy (SCP), so as to provide an evidence-based reference for the rehabilitation treatment of children with SCP. Methods A total of 72 children diagnosed with SCP were recruited from the Department of Rehabilitation Medicine, Children's Hospital Affiliated to Zhengzhou University between December 2023 and December 2024. Participants were randomly assigned into a control group and an observation group using a random number table, with 36 cases in each group. Both groups received conventional rehabilitation training. The control group additionally received MOTOmed-assisted virtual scenario training, while the observation group received MOTOmed-assisted virtual scenario training combined with whole-body vibration training. The intervention lasted for 12 weeks.After 12 weeks of intervention, indicators including lower limb gastrocnemius muscle tone, root mean square (RMS) values of the gastrocnemius during passive ankle dorsiflexion and active ankle plantarflexion, Gross Motor Function Measure 88(GMFM-88) scores for dimension D (standing) and dimension E (walking, running, and jumping), center of pressure (CoP) sway area, 10-meter walk test (10mWT) time, and plantar pressure deviation were compared between the two groups to evaluate the efficacy of the combined intervention on improving lower limb function and gait balance. Results Before the intervention, there were no significant differences in any outcome between the two groups (P>0.05). After the intervention, the gastrocnemius muscle tone score of the lower limbs was significantly lower in the observation group than in the control group (Z=-2.861,P＜0.05). Furthermore, the observation group demonstrated significantly lower RMS values for passive ankle dorsiflexion (t=-2.395) and active ankle plantarflexion (t=-2.058), center of gravity sway area (t=-2.029), 10mWT time (t=-2.538), and plantar pressure deviation (t=-2.094) compared to the control group (P<0.05). Functional assessment indicated a significantly higher GMFM dimension D(t=2.052) and E(t=2.059) score in the observation group compared to the control group (P<0.05). Conclusion Whole-body vibration training combined with conventional rehabilitation and MOTOmed-assisted virtual scenario training may further reduce lower-limb muscle tone, improve walking/running/jumping function, and optimizes dynamic balance and gait stability in children with SCP.
