- Original description
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.Read full original descriptionShow less
Novel Acoustic Biopatch for the Investigation of Dysphagia
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.
Inclusion: 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: Head and neck cancer treatment history; BMI>35 as an exclusion criteria to recruit participants due to limited transmission of acoustics through increased subcutaneous fat.
