Robotic simulation of swallowing disorder

We performed an in-vitro video fluoroscopic swallow study (VFSS) simulation using a robot system that is consisted of artificial tongue, pharynx and mandible. The swallowing robot has wire drive mechanism (16 actuators) these were implemented based on the arrangement of human muscles with respect with the tongue and mandible in anatomy. Then a simulation VFSS to observe the movement of the test foods and liquids on the oral-pharyngeal cavity was performed. VFSS images showed that a robot enables to simulate the movement of human mandible and tongue at swallowing.
