Abstract

BACKGROUND:

Although poststroke dysphagia is an important issue for determining prognosis, the pathophysiology of oral-phase dysphagia has yet to be clarified due to a lack of adequate devices and protocols. The present study investigated the relationships between swallowing pressure production by the tongue and dysphagia in stroke patients using a newly developed method of tongue pressure measurement with a sensor sheet system.

METHODS:

Subjects were 64 stroke patients, including 30 patients with dysphagia. A T-shaped sensor sheet with 5 measuring points was attached to the hard palate to record tongue pressure while swallowing 5 ml of water. The average maximal magnitude and incidence of abnormalities such as asynchronous and/or polyphasic patterns in tongue pressure waves in 5 locations were compared between patients with and without dysphagia.

RESULTS:

The average maximal tongue pressure was significantly smaller in patients with dysphagia than in those without dysphagia. Asynchronous and polyphasic patterns showed a sensitivity of 63 and 87%, and a specificity of 91 and 71%, respectively, for identifying patients with dysphagia.

CONCLUSION:

Tongue pressure production during swallowing appears closely related to poststroke dysphagia. Tongue pressure measurement appears useful for evaluating the pathophysiology of oral-phase dysphagia in stroke patients.
