Rehabilitation Assessment and Progress Tracking System Based on Video Images for Dysphagic Patients

The current cervical range of motion (CROM) and tongue movement measurement methods are not reliable between observers, which is not practical in real-world usage. This research is to develop the cervical range of motion measurement, and tongue movement estimation software, to compare between the developed software and the current measurement techniques, and to test in clinical aspects for reliability and validity assessment. The investigators investigate the developed software in healthy people in phase 1. In phases 2 and 3, the investigators compare the software to the standard measurement methods in dysphagic patients who have head and neck cancer for reliability and validity.
