Dysphagia Study Using Novel Microphone Device

Novel Acoustic Biopatch for the Investigation of Dysphagia

Who can join

Ages 40 to 85 · All sexes

Inclusion Criteria:

* Diagnosis or suspected stroke
* Stroke with additional neurological disorders
* Age between 40 and 85
* Male and Female
* Scheduled to VFSS due to suspected dysphagia, which is determined by bedside water swallowing test and EAT-10 questionnaire as a standard of care.

Exclusion Criteria:

* BMI\>35 as an exclusion criteria to recruit participants due to limited transmission of acoustics through increased subcutaneous fat.
* Head and neck cancer treatment history

About the study

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.
