Establishment of Voice Analysis Cohort for Development of Monitoring Technology for Dysphagia

Recruiting
Conditions
Deglutition Disorders
Interventions
Diagnostic Test: Voice recording before and after dietary intake
Registration Number
NCT05149976
Lead Sponsor
Seoul National University Hospital
Brief Summary

Collection of basic data to develop a technique for monitoring the state of dysphagia using voice analysis.

Detailed Description

* Design: Prospective study

* Inclusion criteria of the patient group

* Patients scheduled for VFSS examination and normal person (without dysphagia) capable of recording voice (selected as a control group for comparison of voice indicators with patients with dysphagia)

* Patients who can record voices such as "Ah for 5 seconds", "Ah. Ah. Ah.", "umm\~\~\~"

* Inclusion criteria of the control group: Patients unable to speak, Patients who cannot follow along, If the VFSS test is a retest

* Setting: Hospital rehabilitation department

* Intervention: After obtaining the consent form for the patient scheduled for the VFSS test, "Ah for 5 seconds", after clearing the throat, "Ah for 5 seconds", briefly cut with a high-pitched sound, "Ah. Ah. Ah", close your lips lightly and make a "ummm\~\~\~\~" sound, and record 2 times each.

Arm && Interventions
GroupInterventionDescription
Residue GroupVoice recording before and after dietary intake- As a result of VFSS (video fluoroscopic swallowing study), the subjects who have residues left around the pharynx or airway
Normal groupVoice recording before and after dietary intake* A person judged normal among VFSS (video fluoroscopic swallowing study) examiners * Normal subjects without symptoms of dysphagia
Aspiration GroupVoice recording before and after dietary intake- VFSS (video fluoroscopic swallowing study) test result, the subjects who have aspiration in the airway
Primary Outcome Measures
NameTimeMethod
Accuracy of machine learning prediction model using voice change before and after dietary intakeday 1

Accuracy measures how well machine learning predicts three groups ('Normal', 'Residue', 'Aspiration') according to voice changes before and after dietary intake.

Secondary Outcome Measures
NameTimeMethod
AUC (Area Under the ROC curve) of machine learning prediction model using voice change before and after dietary intake.day 1

AUC measures how well machine learning predicts three groups ('Normal', 'Residue', 'Aspiration') according to voice changes before and after dietary intake.

mAP (mean Average Precision) of machine learning prediction model using voice change before and after dietary intakeday 1

mAP measures how well machine learning predicts three groups ('Normal', 'Residue', 'Aspiration') according to voice changes before and after dietary intake.

Recall of machine learning prediction model using voice change before and after dietary intake.day 1

Recall measures how well machine learning predicts three groups ('Normal', 'Residue', 'Aspiration') according to voice changes before and after dietary intake.

Accuracy of machine learning prediction model using only voice after dietary intake.day 1

Accuracy measures how well machine learning predicts three groups ('Normal', 'Residue', 'Aspiration') according to voice only voice after dietary intake.

mAP (mean Average Precision) of machine learning prediction model using only voice after dietary intake.day 1

mAP measures how well machine learning predicts three groups ('Normal', 'Residue', 'Aspiration') according to voice only voice after dietary intake.

AUC (Area Under the ROC curve) of machine learning prediction model using only voice after dietary intake.day 1

AUC measures how well machine learning predicts three groups ('Normal', 'Residue', 'Aspiration') according to voice only voice after dietary intake.

Recall of machine learning prediction model using only voice after dietary intake.day 1

Recall measures how well machine learning predicts three groups ('Normal', 'Residue', 'Aspiration') according to voice only voice after dietary intake.
