A research paper published in Frontiers in Neurology collected data on tongue pressure and swallowing function in Parkinson’s disease.
"Previous studies measuring tongue pressure in PD have reported decreased tongue strength and pressure during swallowing, as well as a prolonged tongue pressure rise time, which are symptoms associated with PD severity and dysphagia. In this mini-review, we present a method for measuring tongue pressure and discuss its relationship with dysphagia in PD."
The tongue pressure sensor used to measure swallowing function is a custom Tekscan sensor.
