Abstract
A device can screen swallowing safety and swallowing efficiency. The device includes a processor configured to receive accelerometry data, determine a an A-P and S-I signal summed spectrogram from the accelerometry data, and perform one or more of identifying a missing swallow, identifying that the data was clipped from the start, identifying that the data was clipped from the end, or identifying that the data contains noise. The device can have a user interface configured to provide one or more outputs including at least one of audio or graphics based on these identifications. If the data does not contain these signal quality issues, the device can compare the data against preset classification criteria defined for each of swallowing safety and swallowing efficiency and thus classify each of the swallowing events with a swallowing safety classification and a swallowing efficiency classification.
