The need for non-contact practice during the COVID-19 pandemic has resulted in a rapidly growing interest in digital health technologies (DHTs). Until recently, swallowing evaluations and treatments have been performed face-to-face in the field of dysphagia, which has now encountered huge challenges in the COVID-19 era. This review aims to provide an overview of the DHTs, and investigate the current research trends of DHTs applied to dysphagia evaluation and management. Previous studies on dysphagia using DHTs were reviewed based on four categories: data, machine learning, wearable sensors, and telemedicine. The reports are further discussed for their current limitations and future potentials. We conclude that clinical utility and regulations need to be considered in developing new methods of swallowing evaluation and management based on DHTs.
