A comparative analysis of swallowing accelerometry and sounds during saliva swallows

Accelerometry (the measurement of vibrations) and auscultation (the measurement of sounds) are both non-invasive techniques that have been explored for their potential to detect abnormalities in swallowing. The differences between these techniques and the information they capture about swallowing have not previously been explored in a direct comparison.In this study, we investigated the differences between dual-axis swallowing accelerometry and...
