Neuromuscular Electrical Stimulation for Treatment-Refractory Chronic Dysphagia in Tube-Fed Patients: A Prospective Case Series

Abstract

Objective: The aim of this study was to evaluate the role of neuromuscular electrical stimulation (NMES) in tube-fed patients with severe and chronic dysphagia refractory to traditional swallowing therapy (TT). Patients and Methods: A total of 11 consecutive dysphagic patients with tube-dependent nutrition and who had not responded to 6 months of TT were enrolled. Each patient received NMES for 30 min and TT for 30 min, twice a day, 5 days per week for 4 weeks. In order to evaluate the swallowing impairment, each patient underwent a fiberoptic endoscopic examination of swallowing immediately before the beginning of the treatment, after 2 weeks and after 4 weeks. Results: All enrolled patients managed to complete the swallowing treatment protocol for at least 2 weeks. After the 4-week treatment, 6 of 11 enrolled patients passed to a total oral diet with single or multiple consistencies despite specific food limitations or special preparation or compensation. Five patients, all affected by the most severe form of dysphagia, maintained tube-dependent nutrition. Conclusion: NMES as adjunctive treatment to TT may offer a new possibility for the management of tube-fed patients who are refractory to TT.

Effectiveness of VitalStim therapy in dysphagia treatment: a review article

“…Oproti tomu dvě studie (Blumenfeld, 2016;Bülow 2008) srovnávaly skupinu s tradiční terapií se skupinou absolvující neuromuskulární stimulaci jako jedinou terapeutickou techniku. Zbývající tři práce (Carnaby-Mann, 2008;Ludlow, 2007;Scarponi, 2016) porovnávaly výsledky před a po terapii zahrnující elektrickou stimulaci, respektive kombinaci elektrické stimulace a tradiční terapie. Výsledky přitom nebyly porovnány s kontrolní skupinou.…”
