Dysphagia Study Using Novel Microphone Device
This study is looking for people aged 40 to 85 who have difficulty swallowing (dysphagia) due to a stroke. Researchers are testing a new, non-invasive microphone device, which is a thin film patch, designed to be worn on your chin or between your thyroid and cricoid cartilages. This device collects sounds made while you swallow during a routine videofluoroscopic swallow study (VFSS), which is a special X-ray to watch you swallow. The goal is to use this sound data and machine learning to better understand patterns of abnormal swallowing. The main thing they'll be measuring is the normalized surface acoustic swallowing signal up to 30 minutes after the device is used.
- Study design
- This is an interventional study with a planned enrollment of 50 participants. It is a prospective cohort study, meaning participants are followed forward in time.
- What's involved
- You would have the investigational nanomembrane patch placed and calibrated during your scheduled barium swallowing test. Medical and demographic information will also be collected.
- Compensation
- Not stated in the trial record.
- Follow-up
- The primary measurement will be taken up to 30 minutes post-intervention.

What this trial measures
- Normalized Surface Acoustic Swallowing SignalUp to 30 min post-intervention
Surface acoustic swallowing signals will be collected using a wearable biopatch containing a microphone, placed on study participants. Raw acoustic data will be recorded in voltage and subsequently normalized against background acoustic levels, resulting in a unitless measure expressed in arbitrary units (a.u.).
