AbstractDysphagia is common after stroke. Neuromuscular electrical stimulation (NMES) and fiberoptic endoscopic evaluation of swallowing (FEES) for the treatment of dysphagia have gained in popularity, but the combined application of these promising modalities has rarely been studied. We aimed to evaluate whether combined NMES, FEES, and traditional swallowing rehabilitation can improve swallowing functions in stroke patients with moderate to severe dysphagia. Thirty-two patients with moderate to severe dysphagia poststroke (≥3 weeks) were recruited. Patients received 12 sessions of NMES for 1 h/day, 5 days/week within a period of 2-3 weeks. FEES was done before and after NMES for evaluation and to guide dysphagic therapy. All patients subsequently received 12 sessions of traditional swallowing rehabilitation (50 min/day, 3 days/week) for 4 weeks. Primary outcome measure was the Functional Oral Intake Scale (FOIS). Secondary outcome measures included clinical degree of dysphagia, the patient's self-perception of swallowing ability, and the patient's global satisfaction with therapy. Patients were assessed at baseline, after NMES, at 6-month follow-up, and at 2-year follow-up. Twenty-nine patients completed the study. FOIS, degree of dysphagia, and patient's self-perception of swallowing improved significantly after NMES, at the 6-month follow-up, and at the 2-year follow-up (p < 0.001, each compared with baseline). Most patients reported considerable satisfaction with no serious adverse events. Twenty-three of the 29 (79.3 %) patients maintained oral diet with no pulmonary complications at 2-year follow-up. This preliminary case series demonstrated that combined NMES, FEES, and traditional swallowing rehabilitation showed promise for improving swallowing functions in stroke patients with moderate-to-severe dysphagia. The benefits were maintained for up to 2 years. The results are promising enough to justify further studies.
