Data Science Applications in Communication and Swallowing Disorders (NIH/NIDCD 2K24DC012801; Bracco Diagnostics)FC2023-05-15T10:44:56-05:00

The major goal of this project is to train early, patient-oriented communication and swallowing scientists in big data analyses, including computer machine learning approaches. The project will uncover distinct patterns and severity of swallowing impairments in large groups of patients with high-risk medical diagnoses.

Specific Aims

Aim 1. Refine swallowing phenotypes for five specific diagnoses commonly known to be at high risk for nutritional and health complications related to swallowing impairment including: 1) Stroke, 2) Parkinson’s Disease, 3) Head and Neck Cancer, 4) Dementia and 5) Chronic Obstructive Pulmonary Disease.

Aim 2. Predict swallowing impairment severity classifications based on Modified Barium Swallowing Impairment (MBSImP) overall impression (OI) component scores in each of the five diagnoses using both supervised and unsupervised statistical learning algorithms.

Aim 3. Develop a computerized scoring algorithm using computer vision and machine learning techniques toward minimization of subjectivity, human error and further enhanced reproducibility of swallowing metrics.
