Abstract

Tongue-palate interface pressure during swallowing is of interest in dysphagia research. Interface pressure data collected with a new intra-oral pressure measurement system, OroPress is examined using principle component analysis (PCA). PCA indicated a feature difference between male and female swallowing pressure profiles. This difference is expressed in high dimensional space, where the power in female swallowing pressure was found to have a denser distribution in the eigenvector basis than that of males. This paper presents a method for classifying the testing probes between the two genders in terms of PCA reconstruction.
