Abstract: Objective To observe the effects of electromyographic biofeedback electric stimulation therapy on lower extremities motordysfunction in children with spastic hemiplegic cerebral palsy (CP). Methods According to the consent of the custodians to the new therapy,60 children with spastic hemiplegic CP were divided into treatment group and control group with 30 cases in each group. All children weretreated with motor training, physical therapy and wore the ankle-foot orthosis (AFO). The treatment group was received electromyographicbiofeedback electric stimulation therapy on their lower extremity additionally. Composite Spasticity Scale (CSS) of the hemiplegic lower extremities,the ankle angle of passive dorsiflexion motion, D and E domains of Gross Motor Function Measure (GMFM-88) were performedto comparatively evaluate the effects before and 12 weeks after treatment. Results The outcomes were improved compared with the ones ofpre-treatment (P<0.05), and improved more in the treatment group (P<0.05). Conclusion The electromyographic biofeedback stimulationtherapy in combination with rehabilitation functional training in the treatment for children with spastic hemiplegic CP is more effective onspasticity of the lower extremity, increasing the range of ankle motion, improving gross motor function of lower extremities.
