Abstract: Objective To investigate the effect of electromyographic biofeedback with electric stimulation (Est-EMGBFT) training on dorsiflexion of foot of cerebral palsy children with spastic diplegia type.Methods 66 cerebral palsy children with spastic diplegia type were randomly divided into the treatment group and control group with 33 cases in each group. The treatment group was treated with rehabilitation training plus Est-EMGBFT, while the control group with rehabilitation training only. The manual muscle test (MMT) of tibial muscle and the ankle joint initiative range of motion (I-ROM) were performed before and after 4 courses of treatment, and the treatment group was assessed by electromyographic (EMG) apparatus additionally.Results After treatment, the muscular force of children in the treatment group was higher than those in the control group significantly ( P<0.01) and the level of integrated electromyography (iEMG) and root mean square (RMS) assessed by sEMG increased significantly ( P<0.05), the I-ROM of the treatment group was higher than the control group significantly ( P<0.05).Conclusion Est-EMGBFT training can provide a satisfactory rehabilitation effect for the dorsiflexion of foot of cerebral palsy children with spastic diplegia type.
