Extended transitions between sound, syllables, and words
Syllable segregation
Similarities of AOS and conduction aphasia
Visible arctic groping
Inconsistency of attic errors
Sequencing errors

Aos definition
Is a phonetic motoric disorder characterized by impaired motor planning. It is not a language disorder or disorder of muscle tone
Nonverbal apraxia and AOS
commonly seen along with AOS but both can be seen in isolation
cause of AOS
damage to premotor and supplementary motor cortex
T/F In pure AOS abnormality of muscle tone and pathological reflexes will be observed
False
repeating a command e.g. “cough” is commonly seen in individuals with significant ____
nonverbal oral apraxia
Similarities of AOS and ataxic dysarthria
both may demonstrate a predominance of arctic and prosodic abnormalities
both have normal motor exam
Differences of AOS and ataxic dysarthria
ataxic- irregular speech AMRs, irregular arctic errors, variable prosodic abnormalities more pervasive.
Aos- may have better automatic speech, perceived sound substitutions more common
Do AOS and aphasia commonly co occur
yes, usually with nonfluent aphasia
can an aphasia mask aos
yes, less likely that an dos will mask aphasia because there will also be comprehension and reading/writing problems
