dysarthria vs apraxia Flashcards
what are some characteristics of dysarthria?
slowness, weakness, incoordination
what are some specific characteristics of articulation with dysarthria?
simplification, distortions, substitutions, errors are consistent, more complex units are more difficult, final position more difficult
response to stimulation for dysarthria
may alter performance to match auditory-visual model, best response to demonstration of specific articulatory gstures
what are some charcteristics of apraxia?
articulation erros, absence of muscle weakness, weakness, incoordination, due to disruption of cortical programming for the voluntary production of speech sounds, self monitor, groping
results of oral peripheral examination may show….
obvious dysfunction in executing voluntary movements. vegetative functions performed adequately, performance improves with faster rate, prosody disturbed, non fluent, slow labored speech during voluntary attempts
results of oral peripheral examination for dysarthria may show….
slowness, weakness, vegetative function (chewing, swallowing) may be disturbed, incoordinated
what are some specific characteristics of articulation with apraxia?
transpositions, reversals, (padada for potato, nana for banana), perseverative and anticipatory errors, fewer distortions, more substitutions, intrusive additions, inconsistency
response to stimulation with apraxia
best performance if pt sees and hears model
dysarthria results from
muscular impairment
for dysarthria, muscular weakness, slowness, or incoordination can affect which processes of speech?
all.
what is the most common feature of dysarthria
articulation followed by voice, resonance, and fluency
dysarthria is often confused with
AOS
differentiating characteristic between dysarthria and apraxia is that dysarthria is associated with
muscular impairment and AOS is not
