The efficacy of low-frequency electrical acupoint stimulation plus rehabilitation training in improving the swallowing function of stroke survivors

Abstract

Objective To test the efficacy of low-frequency electrical acupoint stimulation plus rehabilitation training in improving swallowing function after stroke. Methods Eighty dysphagic stroke patients were randomly allocated into 2 groups of 40.Patients in the experimental group received low-frequency electrical acupoint stimulation plus 2 courses of rehabilitation training.Control group patients received the same protocol,but the electrical stimulation was not over acupoints.Their swallowing function was assessed using the Kubota water drinking test.Results After treatment,both groups showed significantly lower Kubota scores compared with pre-treatment.Prepost test difference was 1.25 ± 0.78 in the experimental group and 0.70 ± 0.72 in the control group,a significant difference.The total recovery rate in the experimental group was 87.5％.In the control group it was 55％.The improvement in swallowing function was significantly better in the experimental group. Conclusion Both groups showed a significant improvement in swallowing function,but low-frequency electrical acupoint stimulation increased the effectiveness of the rehabilitation training.
