"The purpose of this study was to compare the effects of functional electrical stimulation and sensory- level electrical stimulation on ankle function of the patients with hemiplegia. The objects of this study covered 20 patients with hemiplegia, age from 50 to 80 years old and fell into two groups which was a group of functional electrical stimulation and a group of sensory-level electrical stimulation. The clinical assessment were obtained before and after four weeks electrical stimulations on affected ankle dorsiflexors that included the range of motion of the active anlkle dorsiflexion, modified ashworth scale of plantarflexors and muscle function of anlkle dorsiflexors. The results of this study were as follows; The functional electrical stimulation has been found to increase range of motion of the anlkle dorsiflexion, muscle function of anlkle dorsiflexors and reduce spasticity of plantarflexors. sensory-level electrical stimulation has been found to increase range of motion of the anlkle dorsiflexion, but muscle function of anlkle dorsiflexors and spasticity of plantarflexors have not shown statistical significance. This study suggests that functional electrical stimulation is an effective treatment in gait rehabilitation of patients with hemiplegia and sensory- level electrical stimulation need to be more research to confirm therapeutic effectiveness. we are continuing to explore this therapeutic modality as rehabilitation interventions to improve the patient's hemiplegic gait pattern. Key words : ankle function, electrical stimulation, hemiplegic gait."
