Study Type: Interventional
Study Phase: Not Applicable
SUMMARY
This study aims to collect swallowing acoustics with a novel non-invasive wearable surface microphone device during routine work-up, videofluoroscopic swallow study (VFSS), of patients with dysphagia (swallowing trouble). The collected microphone data will be analyzed to find the pattern of abnormal swallowing by machine learning algorithm.

Experimental: Novel Acoustic Biopatch for the Investigation of Dysphagia Cohort
The device is composed of a sensor (disposable part) and a circuit (reusable part).~The device will be applied to the anterior neck of dysphagia symptomatic patients who will be accessed with routine dysphagia investigation, such as standard swallowing evaluation with a modified barium swallow (VFSS). Device will be applied by authorized investigators to specific area to target specific neck muscles where no interference occurs for X-ray imaging (VFSS) interpretation. Acoustic data collected via device will be compared with X-ray imaging (VFSS) to train Convolutional neural network (CNN) algorithm to improve accuracy and to determine accuracy of device.
