Treating apraxia of speech (AOS) with EMA-supplied visual augmented
Feedback History of Problem In 1999, Katz et al. explored EMA as a means of remediating fricative articulation deficits. They conducted this experiment on a 63-year-old woman with Broca’s aphasia and moderate-to-severe AOS. For 1-month she was provided with: EMA visual feedback for tongue tip position during fricative production and foil treatment in which a computer program delivered voicing-contrast stimuli for simple repetition. There was improvement from the visually guided feedback. The phonetic contrast treated in the foil condition showed only slight improvement, with a return to baseline 10 weeks later. A number of studies have shown that facilitatory effects ...
