Dysphagia Study Using Novel Microphone Device
Novel Acoustic Biopatch for the Investigation of Dysphagia
Emory University
50 participants
Oct 12, 2025
INTERVENTIONAL
Conditions
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.
Eligibility
Inclusion Criteria5
- 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 Criteria1
- Head and neck cancer treatment history

Interventions
* An investigational nanomembrane patch, which is a thin film, is designed to collect acoustics while swallowing. * The Microphone is also placed between the thyroid and cricoid cartilages to record swallowing acoustics.
