Flaccid Dysarthria
|
Damage: lower motor neuron of cranial or spinal nerves
Cranial Nerves involved: V, VII, X, XII Characteristics (voice): hoarse, monopitch, monoloudness, breathy voice -audible inspiration -short phrases -hypernasal, nasal emission -rapid and progressive weakness with use; recovery with rest |
|
|
Spastic Dysarthria
|
Damage: bilateral damage to upper motor neurons
Area(s) of Lesion: cortical areas, basal ganglia, pons, medulla, intenal capsule Characteristics:(voice)monopitch , monoloudness harshness, strained-strangled voice quality, resonance disorders (hypernasality), pitch breaks -Increase muscle tone -Bilateral facial weakness |
|
|
Hypokinetic Dysarthria
|
Damage: Basal ganglia
Characteristics: short rushes of speech, inappropriate silent intervals, increased rate in segments and short phrases -Masklike face, tremors in resting facial (diminishes when movements are voluntary) -Decreased swallowing, drooling |
|
|
Hyperkinetic Dysarthria
|
Damage: Basal ganglia
Characteristics: forced and sudden inspiration or expiration voice tremors, inconsistent articulation problems: impercise consonants, distorted vowels -Facial tics, chorea, severe contracting spams, dystonia |
|
|
Ataxic Dysarthroa
|
Damage: Cerebellar System
Characteristics: uncordinated jerky inaccurate slow imprecise and halting movements -Irregullary articulatory breakdowns and vowel diistortions -Hypotonia, gait disturbances speech quality compared to druken speech |
|
|
