Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This investigation evaluates the effectiveness of a device called the Aspirometer, which uses high resolution cervical auscultation (HRCA), in detecting when food or liquids enter the airway (aspiration) of the person swallowing, whether the person swallowing shows signs of aspiration (coughing) or not.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This aim of the project seeks to discriminate normal from abnormal airway protection and kinematic functions noninvasively via machine-learning analysis of Aspirometer/HRCA (high resolution cervical auscultation) signals, with similar accuracy as human judgment of VF. Hypothesis: Advanced data analytics can detect pathological airway protection in HRCA signal signatures with 90% accuracy when compared to a human expert's airway protection ratings from VF images. Analytical algorithms that can learn from data (e.g., Bayes' learning) will be used to infer about the continuum of abnormal airway protection during swallowing.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Videofluoroscopic Swallow Study + Aspirometer

Consecutively referred patients for modified barium swallow due to suspicion of dysphagia with aspiration, undergo the modified barium swallow test with Aspirometer sensors taped to the anterior neck. Signals are time-linked to images.

Group Type EXPERIMENTAL

Aspirometer

Intervention Type DEVICE

a triaxial accelerometer and a contact microphone affixed with tape to patient neck, a data accrual infrastructure, algorithms that decode swallow physiology noninvasively

Videofluoroscopic X-ray

Intervention Type DEVICE

MBS is a fluoroscopic diagnostic test to evaluate swallowing physiology. Its images are judged by humans trained to do so.
