AOS Assessments Flashcards
Who created the Apraxia Battery for Adults (ABA)?
Dabul, 2000
Who created the comprehensive aphasia test (CAT)?
Swinburn, Porter and Howard, 2005
Who created the Boston Disgnostic Aphasia Examination?
Kaplan and Goodglass, 1983
What are some featured assessments in the ABA?
- DDK rates (SMRs / AMRs)
- increasing word length
- repeated trials test
What are AMRs?
repeating single syllables “pa” “ta” “ka” as quickly as a patient can
What are SMRs?
repeating sequences of syllables = “pa-ta-ka”
What are some limitations of the ABA?
- old / outdated
- very broad in terms of keeping up with any inconsistencies in speech -> need to record it
What are some advantages of the ABA?
- gives examples
- will give a good idea whether someone has apraxia or not
Who created the Apraxia of Speech Rating Scale (ASRS)?
Strand et al., 2015
What does the ASRS do?
- originally designed to study progressive aphasia/AOS
- aims to reduce errors in perceptual judgements and improve consistency
- quantifies the presence and severity of specific characteristics of AOS
What is the ASRS?
- 5 point rating scale that describes presence and severity of AOS
- 16 items organised according to whether they are discriminative or can also be present in aphasia and/or dysarthria
When do you use the ASRS?
scored after listening to conversational speech, picture description, words and sentence repetition and AMR/SMR tasks
What are the advantages of the ASRS?
- good specificity and sensitivity - unlikely to identify someone as having AOS if they didn’t already have the diagnosis
- good interior reliability
Who created the diagnostic categories of behavioural characteristics?
Waumbaugh et al., 2006
What are the diagnostic categories of behavioural characteristics?
- a patient demonstrating all 6 primary characteristics has a high probability of having AOS
- … demonstrating non-discriminative characteristics and most of the primary characteristics has a moderate probability of having AOS
- … demonstrating four characteristics associated with other disorders has a low probability of AOS
- … demonstrating any of the ruling out characteristics does not have AOS
What are the first 3 steps in assessing AOS?
- observation (verbal/non-verbal)
- oral examination
- informal assessment of speech (recorded)
What are some areas to assess regarding speech?
- spontaneous speech
- imitation
- reading aloud
- picture description
- with different levels of complexity
What are some other areas to assess?
- intelligibility - single words / sentences / continuous speech
- communicative ability - strategies / areas of strength
- client’s understanding of and response to their difficulties
- communication partners response and understanding
What are some ‘easy tasks’ with regards to informal AOS assessments?
- automatic tasks i.e counting, singing
- AMRs
- isolated sounds or single words
- CVCs with duplicated consonant i.e mum, kick
What are some ‘difficult tasks’ with regards to informal AOS assessments?
- SMRs
- multisyllabic words with unstressed initial syllable i.e catastrophe
- words/sentences of increasing length
- conversation / narrative
Why are cultural and linguistic factors important?
- although AOS affects prosody and articulation, can impact communication differently i.e if they speak a different languages where tone is important
- accommodations and modifications can be made to the testing process but will affect standardisation
How to assess for impact with AOS?
- no specific assessment but AOS can co-occur with aphasia so questionnaires for aphasia can be used i.e COAST, AIQ, etc
Who made the Communation Outcome After Stroke (COAST)?
Long et al., 2008
Who made the aphasia impact questionnaire (AIQ)?
Swinburn, 2018
