final exam Flashcards
flaccid dysarthria
impairments of lmns in cranial or spinal nerves (pns damage)
flaccid dysarthria causes
caused by any disorder that disrupts flow of neural impulses along lmns travel to reach muscles
location of damage flaccid
final common pathway
final common pathway
last and only road nueral impulses from umns travel to reach muscles
flaccid injuries
brainstem stroke, growing tumor, viral or bacterial infections, physical trauma, surgical accidents, mysathenia gravis, guillain-barre syndrome, polio, muscular dystrophy, progressive bulbar palsy
speech charateristics flaccid
- May NOT demonstrate deficits in all areas; severity level will vary
- Hallmarks: slow-labored articulation, marked degrees of hypernasal resonance, hoarse-breathy phonation
resonance characteristcs flaccid
- Hypernasality most common
- Nasal emission
- Weak pressure consonants
- Shortened phrases
articulation characteristics flaccid
imprecise consonant production
phonation characteristics flaccid
Phonatory incompetence (incomplete adduction of VFs during phonation) giving hoarse-breathy voice
respiration characteristics flaccid
- May not be affected
- If it is, you would see reduced loudness and speaking on residual air
prosody characteristics flaccid
- Monopitch, monoloudness
- Not unique to flaccid so not a diagnostic marker
evaluation tasks
- Look for clusters of symptoms when trying to diagnose
- Conversational speech and reading: Can evoke errors of resonance, arctic, respiration, and prosody
- AMR: /puh puh puh/ /tuh tuh tuh/ /kuh kuh kuh/. Will highlight a slowed rate of phoneme production
- Prolonged vowel: Will elicit breathy voice quality heard in phonatory incompetence
- Speech stress test: Necessary IF myasthenia gravis is suspected
treatment flaccid
- Treatments are according to which cranial nerve
- Needs and abilities vary greatly
resonance treatment flaccid
Velar strength-training procedure; modification of speech; reduce rate
phonation treatment flaccid
Pushing and pulling procedures, hard glottal attack
prosody treatment flaccid
Pitch range exercises, intonation profiles, contrastive stress drills
respiratory treatment flaccid
Correct posture, prosthetics, speaking immediately on exhalation
spastic dysarthria
bilateral damage to umn tracts
pyramidal system spastic
damage = weak/slow skilled movements
extrapyramidal system spastic
damage = weakness, increased muscle tone (spasticity), and abnormal reflexes
injuries spastic dysarthria
- stroke - most common; only occurs in LH and RH as a combo OR single in brainstem
- degenerative diseases: ALS, multiple sclerosis
- TBI
-infection
-tumors
speech characteristics spastic
-imprecise consonants, monopitch, monoloudness, reduced stress, harsh vocal quality
- Errors result bc of spasticity, slowness, weakness in vocal-tract muscles
articulation characteristics spastic
Imprecise consonant productions, vowel distortions
phonation characteristics spastic
Harsh vocal quality, Strained-strangled, Low pitch
