Overview

The goal of this study is to set up a database of oral-motor and speech functions of post-stroke patients in Hong Kong via an artificial intelligence-powered mobile-health application. The main study objectives are:

1. To establish an image database of oral-facial movements of neurologically healthy adults and adult stroke patients in Hong Kong.
2. To evaluate the oral-motor functions of neurologically healthy adults and stroke patients via instrumental and behavioral assessment.
