Dysarthria Types Flashcards
Flaccid:
location of lesion
primary deficit
LMN
weakness
(breathy, hoarse, slow)
Spastic:
location of lesion:
primary deficit:
bilateral UMN
Spasticity
Ataxic:
location of lesion:
primary deficit
cerebellum
incoordination
Hypokinetic:
location of lesion:
primary deficit
assoc. with ?
basal ganglia dopamine depleation
rigidity and decreased ROM
PD
Hyperkinetic:
location of lesion:
primary deficit:
basal ganglia excess dopamine
involuntary movements
unilateral upper motor neuron:
location of lesion
primary deficit:
unilateral UMN
weakness, incoordination, spasticity
Hyperkinetic:
underlying problem ?
salient speech characteristics: articulation?
prosody?
accelerated ?
other characteristics:
involuntary
excessive actviity in
etiology: ?
tx: increase ? + ?
employing … to reduce?
acetylcholine
unpredictable breakdowns
abnormal
-rate with inconsistent AMRs
movement
dopaminergenic nerve fibers
Huntington’s
increase vocal pitch+slow rate
sensory tricks /involuntayr movements
Hypokinetic:
salient speech characteristics: rate =
dysfluency ?
-may also present as
reduced ?
too fast
extremely rapid repetitions
-cluttering
loudness
Ataxic:
2 types
predominantly scanning: .. and…
predominantly erratic: poor ? with inconsistent? (also sounds??)
slow rate with irregular?
… of movement
possible etiologies:
…diseases
..
excess and equal stress (unstressed syllables are stressed)
poor prosodic control w/inconsistent articulatory breakdowns
AMRs
inconsistency and inaccuracy of movement
drunk speech
degenrative diseases
CVA
Spastic:
underlying problem: weakness=
spasticity=
salient speech characteristics:
slow ///
…voice quality
effortful ?
Chart info: must have lesions in BOTH
direct activation pathway
indirect activation pathway
rate with regular AMRs/pacing
strained-strangled voice quality
effortful speech
right and left hemispheres to produce bilateral UMN damage
Flaccid:
common etiology
ALS
