Electrophysiological patterns of oropharyngeal swallowing in multiple sclerosis

Highlights • Electrophysiological abnormalities of oropharyngeal swallowing are very frequent in MS, and often occur in patients without clinical symptoms of dysphagia. • Prolongation of suprahyoid/submental muscle EMG activity and increase of the interval between onset of this activity and onset of...

Description
Summary:Highlights • Electrophysiological abnormalities of oropharyngeal swallowing are very frequent in MS, and often occur in patients without clinical symptoms of dysphagia. • Prolongation of suprahyoid/submental muscle EMG activity and increase of the interval between onset of this activity and onset of the laryngeal–pharyngeal mechanogram during oropharyngeal swallowing seem to be markers of dysphagia in multiple sclerosis. • The most marked electrophysiological abnormalities of oropharyngeal swallowing are found in secondary progressive multiple sclerosis.
