Interferential current sensory stimulation through the neck skin improves airway defense and oral nutrition intake in patients with dysphagia: a double-blind randomized controlled trial

摘要

BackgroundNeuromuscular electrical stimulation with muscle contraction, administered through the skin of the neck, improves a patient’s swallowing ability. However, the beneficial effects of transcutaneous electrical sensory stimulation (TESS), without muscle contraction, are controversial. We investigated the effect of TESS, using interferential current, in patients undergoing dysphagia rehabilitation.
