In particular, measurements taken from the superior surface of the tongue revealed stiffness values that were highest for the flaccid and flaccid-spastic dysarthria groups and lowest for the hypokinetic and spastic dysarthria groups.
Orofacial stiffness measures were predicted to be lower than normal in individuals with flaccid, mixed flaccid-spastic, and possibly ataxic dysarthrias and higher than normal in those with hypokinetic and spastic dysarthrias [3,39,51-52].
