Assessment protocol for acquired apraxia of speech.

PMID 37851756WHAT IT FOUND
A draft Brazilian Portuguese acquired apraxia of speech protocol was built from controlled word lists and standard tasks, but it has not yet been tested in patients or healthy speakers.
Key findings
01This study aimed to develop a Brazilian Portuguese assessment protocol for acquired apraxia of speech with important diagnostic variables and phonologically balanced stimuli.
02The word lists were controlled for syllabic and accentual patterns, phonetic and phonological variables, and word frequency, and the Repetition and Reading Aloud lists showed a significant Spearman correlation (ρ = 0.34; p < 0.001).
03The protocol is currently a draft for the pilot study and still needs comparison with healthy individuals and AOS patients.

What it does not show
The protocol was not tested with people who have acquired apraxia of speech or with healthy speakers. It is described as a draft for a pilot study, not a validated assessment instrument. No cutoff scores or diagnostic accuracy data were reported. Phonotactic probability was not controlled because the authors said there is insufficient research on this theme in Brazil. The authors note that there is no internationally recognized gold standard protocol, and speech-error classification by clinicians can show low interrater agreement.
The easy way to misread this
Do not read this as a validated assessment protocol. It was built and compared as word lists, but it was not tested with people who have AOS or with healthy speakers, so it cannot yet guide diagnosis.
