DEVICE, SYSTEM AND METHOD FOR DETECTION AND MONITORING OF DYSPHAGIA OF A SUBJECT

摘要

The present invention relates to a device, system and method for automatic detection and progression monitoring of dysphagia of a subject, in particular after stroke. The device comprises a signal input for obtaining a mastication signal indicating mastication of the subject, an audio signal representing sounds generated by the subject and a swallowing signal indicating swallowing of the subject, a signal processor for detecting mastication abnormalities from said mastication signal, mastication-to-swallow abnormalities from said mastication signal and said swallowing signal, and aspiration episodes from said audio signal and said swallowing signal, a dysphagia detector for detecting onset and/or progression of dysphagia from detected mastication abnormalities, mastication-to-swallow abnormalities and aspiration episodes and for generating a dysphagia signal indicating information regarding dysphagia of the subject, and a signal output for outputting said dysphagia signal.
