Motor speech Flashcards
What is not a common etiology of motor speech disorders?
Parkinson’s disease
What is a common etiology of motor speech disorders?
Huntington’s disease, seizure disorders, and brainstem stroke
Nonverbal oral apraxia is associated with a lesion in the
frontal and central opercula (the operculum is a brain structure next to the insula that is involved in sensory, motor, autonomic, and cognitive processing); it plays a role in behavioral planning and motor functioning
What is the etiology of dysarthrias?
issue to the peripheral or central nervous system
What is the etiology of flaccid dysarthria?
lower motor neuron damage, especially to muscles and/or CNs involved in speech
How does flaccid dysarthria affect articulation?
weak and imprecise consonants
How does flaccid dysarthria affect respiration?
reduced subglottal air pressure and short phrases
How does flaccid dysarthria affect phonation?
harsh, monopitch and monoloudness, short phrases, breathy; you can hear them breathing;
How does flaccid dysarthria affect resonance?
hypernasality; air coming out of the nose
What is the neuromotor basis of flaccid dysarthria?
hypotonia and weakness
What is the etiology of ataxic dysarthria?
damage to the cerebellum
What is the neuromotor basis of ataxic dysarthria?
incoordination
How does ataxic dysarthria affect articulation?
imprecise consonants, vowel distortion,
How does ataxic dysarthria affect prosody?
long time between words and syllables; slow rate of speech; excessive and even stress
How does ataxic dysarthria affect resonance?
hyponasality (not a prominent feature)
How does ataxic dysarthria affect phonation?
monopitch; monoloudness; harshness
How does ataxic dysarthria affect respiration?
paradoxical breathing
Regarding articulation, all dysarthria types result in
imprecise consonants
Regarding phonation, all dysarthria types result in
monopitch and monoloudness
Which dysarthria types do not cause vowel distortions?
flaccid and hypokinetic
Regarding prosody, which dysarthria types do not cause excess and equal stress?
flaccid and hypokinetic
Which dysarthria types do not cause a slow rate of speech?
flaccid and hypokinetic
Which dysarthria types cause hypernasality?
flaccid, unilateral upper motor neuron, spastic, mixed, hyperkinetic
Which dysarthria type causes hyponasality?
ataxic
Which dysarthria types cause mild hypernasality?
hypokinetic
Which dysarthria type does not cause someone to produce short phrases?
ataxic; flaccid
What is the neuromotor basis for hyperkinetic dysarthria?
abnormal movements
What is the neuromotor basis for hypokinetic dysarthria?
reduced range of motion and reduced movements
What is the neuromotor basis for unilateral upper motor neuron dysarthria?
weakness and spasticity, just like spastic dysarthria
