Abstract: Objective To observe the effect of low frequency electrical stimulation on dysphagia after stroke. Methods 60 patients with dysphagia after stroke were divided into treatment group and control group with 30 cases in each group. The control group was treated with swallowing exercise, while the treatment group was treated with low frequency electrical stimulation in addition. They were assessed with Fujishima's swallowing evaluation before and after treatment. Results The score increased after treatment in both groups (P<0.05), and increased more in the treatment group than in the control group (P<0.05). Conclusion Low frequency electrical stimulation can improve the effects of swallowing exercise on dysphagia after stroke.

Key words: stroke, dysphagia, low frequency electrical stimulation, swallowing exercise
