Assessment of unilateral uppermotor neuron dysarthria
Answers
Dysarthria refers to a group of neurogenic speech disorders characterized by "abnormalities in the strength, speed, range, steadiness, tone, or accuracy of movements required for breathing, phonatory, resonatory, articulatory, or prosodic aspects of speech production" (Duffy, 2013, p. 4).
These abnormalities are due to one or more sensorimotor problems—including weakness or paralysis, incoordination, involuntary movements, or excessive, reduced, or variable muscle tone (Duffy, 2013).
