METHOD AND SYSTEM OF SEGMENTATION AND TIME DURATION ANALYSIS OF DUAL-AXIS SWALLOWING ACCELEROMETRY SIGNALS

摘要

The proposed invention is a method and system for the segmentation of dual-axis accelerometry signals for the purpose of identifying problematic swallowing events. The method and system employ a sensor, a data collection means including an algorithm for analysis of the data. The proposed invention considers the stochastic properties of swallowing signals in both directions, A•P and S-I to extract events associated with swallowing. A segmentation algorithm may be applied to the signals to establish the time duration of swallows and swallows may be classified with respect to gender, body mass index, age or types of swallow.
