Final Exam Flashcards
Flaccid Dysarthria cause
Anything that disrupts flow of motor impulses along cranial or spinal nerves that innervate muscles of speech production. Damage to LMN.
Conditions that damage LMN- Flaccid Dysarthria
- physical trauma, 2. brainstem stroke, 3. GB syndrome, 4. myasthenia gravis, 5. polio.
Other: Tumor, muscular dystrophy, progressive bulbar palsy.
Flaccid Dysarthria speech characteristics
Hypernasality, imprecise consonants, hoarse-breathy phonation. Monopitch/monoloudness, shortened phrases, reduced loudness, strained vocal quality, nasal emissions.
Flaccid Dysarthria Eval Tasks
Conversational speech and reading
AMR task
Prolonged vowel
Conversational speech and reading- Flaccid Dysarthria
evokes errors of resonance (hypernasality), articulation (imprecise consonants), prosody (monopitch/monoloud)
AMR Task- Flaccid Dysarthria
evokes slow rate of phoneme production
Flaccid Dysarthria Treatment
Grouped by cranial nerve or combination of cranial nerve damage.
Individualized for each patient
Flaccid Dysarthria Characteristics
weakness in speech/respiratory musculature
muscle weakness, hypotonicity, atrophy, paralysis, and hypoactive reflexes of involved speech system musculature
Spastic Dysarthria cause
Bilateral Upper Motor Neuron damage
Spastic Dysarthria causes of bilateral UMN damage
Stroke, degenerative diseases, TBI, brain infection, tumor
Spastic Dysarthria specific conditions
Multiple Sclerosis, ALS
Pseudobulbar affect
uncontrollable crying or laughing. Caused by damage to areas of brain important in inhibiting emotions. spastic dysarthria
Pseudobulbar palsy
weakness and slowness in muscles of tongue, velum, larynx, pharynx caused by damage to upper motor neurons. Spastic dysarthria.
Amyotrophic Lateral Sclerosis (ALS)
Terminal degenerative disease
unknown cause
causes spastic when UMN involvement predominant
Multiple Sclerosis (MS)
Immunologic disorder
inflammation/destruction of myelin sheath
Spastic Dysarthria speech characteristics
Result of: spasticity, slowness, weakness in vocal tract muscles
Imprecise consonants
harsh vocal quality, strained-strangled vocal quality
hypernasality
monopitch/monoloud, short phrases, slow rate
Spastic Dysarthria eval tasks
Conversational speech and reading
AMR task
Vowel prolongation
Conversational speech and reading- Spastic Dysarthria
Evokes: hypernasality (resonance), imprecise consonants (articulation), monopitch/monoloudness (prosody)
AMR task- Spastic Dysarthria
Evokes slow rate (prosody)
Vowel prolongation- Spastic Dysarthria
Evokes harsh vocal quality, strained-strangled vocal quality (phonation)
Spastic Dysarthria Treatment
Patient specific
Primary goals target: phonation, articulation, prosody, resonance
Resonance not significantly affected
Spastic Dysarthria phonation treatment
head neck relaxation exercises
easy onset
yawn-sigh exercises
Spastic Dysarthria articulation treatment
stretching tongue and lips
traditional artic drills- intelligibility, phonetic placement, exaggerating consonants
Spastic Dysarthria prosody treatment
pitch range exercises
intonation profiles
contrastive stress drills
chunking utterances
Spastic Dysarthria resonance treatment
pharyngeal flap procedure
teflon paste
pharyngeal wall procedure
Unilateral Upper Motor Neuron Dysarthria cause
Any condition that damages upper motor neurons on one side of the brain
UUMN Dysarthria neuro basis
Damage to muscles of lower face and tongue (receive unilateral innervation)
UUMN Dysarthria causes
Any condition that causes UUMN damage
In left hemisphere can co-occur w/aphasia or AOS
In right hemisphere can co-occur w/cognitive & visual deficits associated with that side of brain
UUMN Dysarthria causes
Stroke- most common
Tumors- not common
TBI- not common
