Objectives: The aim of this work was to investigate the efficacy of masticatory muscles electric stimulation in improving swallowing in spastic diplegic CP.Method: Thirty children were enrolled in this study and randomly assigned into two groups; group A received masticatory muscles electrical stimulation plus traditional physiotherapy program), and group B (traditional physiotherapy program only). (FOIS) was used to evaluate and follow feeding level progress.. This measurement was taken before treatment and after 12 weeks of treatment for all patients. The children parents in both groups A and B were instructed to complete 3 hours of home routine program. Results: Data analysis were available on the 30 spastic diplegic cerebral palsy children participated in the study. No significant difference was recorded between the mean values of all parameter of the two groups before treatment. By comparison of the two groups results after treatment there was significant improvement in (FOIS) in favor of the study group. Conclusion: According the results of this study supported by the relevant literature it can be concluded that the combined effect of physiotherapy training program in addition to masticatory muscles electrical stimulation can be recommended in improvement of feeding level progress in spastic diplegic cerebral palsy children.
