Prediction of Functional Health Status and Aspiration Using Multiple Dysphagia Scales Over 6 Months After Acute Stroke

Prediction of Functional Health Status and Aspiration Using Multiple Dysphagia Scales Over 6 Months After Acute Stroke: Prospective, Observational, Parallel Group, Case-control Trial

In order to discover dysphagia scales, which shows meaningful predictability of aspiration and functional health status in patients with acute stroke, authors plan to find out more predictable indicators than existing penetration-aspiration scale (PAS) to validate their predictions and their internal and external validity over 6 months following stroke .

To determine the dysphagia scale with significant predictions of aspiration and functional health status in patients with acute stroke, video-fluoroscopic swallowing study (VFSS) will be performed to the patients who will be referred for VFSS among stroke patients who would be diagnosed by Brain MRI / CT. When any type of dysphagia is found, participant will be assigned to the test group (DYS), and when no dysphagia is found, they will be assigned to the control group (NOD).

Numerous kinds of assessment will be conducted before and after VFSS, before discharge, and 3, 6, and 9 months after the stroke onset.

Inclusion Criteria:

• brain MRI / CT-based stroke patients who were referred for VFSS

Exclusion Criteria:

• In case of a history of dysphagia
• Unstable patient in neurology
• 2 or higher of NIHSS 1a (level of consciousness)
• Patients with other neurological diseases
• Patients with decompression skull resection
• Refusal of participation
