Objective To observe the clinical efficacy of modified VitalStim electroacupuncture in the treatment of dysphagia in stroke patients with cricopharyngeal dysfunction (CPD). Methods A total of 40 stroke survivors with CPD in Department of Rehabilitation Medicine of The Second Affiliated Hospital of Chongqing Medical University from Oct. 2018 to Oct. 2019 were randomly divided into experimental group and control group, with 20 patients in each group. The experimental group received modified VitalStim electroacupuncture＋routine rehabilitation, and the control group received routine electroacupuncture＋routine rehabilitation. The patients in the 2 groups were assessed by video fluoroscopic swallowing study (VFSS) and laryngeal ultrasonography before and after treatment. The swallowing time, cricopharyngeal muscle expansion and hyoid bone displacement were analyzed respectively. The changes of above indexes were compared between the 2 groups before and after treatment. Adverse events and complications were observed during the treatment. Results Compared with before treatment, shortened swallowing time and increased cricopharyngeal muscle expansion and hyoid bone displacement were observed in both groups after treatment (all P＜0.01). After treatment, the swallowing time of patients in the experimental group was shorter than that in the control group, and the cricopharyngeal muscle expansion and hyoid bone displacement were greater than those in the control group (all P＜0.01). No adverse events or complications occurred during the treatment. Conclusion Routine rehabilitation combined with routine electroacupuncture or modified VitalStim electroacupuncture can improve the swallowing function of stroke survivors with CPD by increasing the hyoid bone displacement and relieving the cricopharyngeal muscle spasm, and modified VitalStim electroacupuncture has better clinical efficacy.
