Abstract: Objective To value the application of surface electromyography(sEMG)in assessing the functional electrical stimulation(FES)used in children with spastic diplegia.Methods 20 children with spastic diplegia were treated with FES.They were assessed with the sEMG and the clinical assessment before and after treatment.Results After treatment,the iEMG of the biceps brachii and quadriceps decreased significantly on the functional position,but increased significantly when the muscles contracted.Conclusion FES can reduce the spasticity and increase the strength of the limbs in children with spastic diplegia.The sEMG can be used as an objective assessment tool.

Key words: spastic diplegia, functional electrical stimulation, surface electromyography(sEMG)
