My wife diagnosed with PSP for several years has all sort of problems associated with a loss of muscular control for respiration, elocution, swallowing etc...She is also more and more often biting her tongue which may cause severe pains.
I came across a device, the Mandibular Advancement Splint (MAS), that is supposed to solve part of this problems and is used primarily to combat apnee but is potentially useful for other applications.
This device is described in: en.wikipedia.org/wiki/Mandi...
Has anyone involved with PSP got any experience with such a device?
Has anyone involved with PSP experienced similar problems and tested any solution?
