Primaire uitkomstmaten
1) Quantitative measure of verbal effectiveness (Ruiter, Kolk, Rietveld, Dijkstra & Lotgering, 2011), based on experimentally adapted scenarios of the ANELT (Blomert, Koster & Kean, 1995) and Picture Description Task (2008)
2) Quantitative measure of verbal efficiency (Ruiter, Kolk, Rietveld, Dijkstra & Lotgering, 2011), based on experimentally adapted scenarios of the ANELT (Blomert, Koster & Kean, 1995) and Picture Description Task (2008)
Achtergrond van het onderzoek
The aim of the pilot study is to examine the effectiveness of therapeutic application called SimpTell (Language in Interaction Consortium, 2018). SimpTell is an acronym for Semi-independent Interactive Multimodal Production Training of ELLipses (in Broca’s aphasia). The app supports speech and language therapists (SLTs) in teaching Dutch speaking persons with chronic Broca’s aphasia to produce reduced utterances (i.e., ellipses) to compensate for their sentence production difficulties. Ellipses resemble telegraphic style (e.g., Stroke last year. Speaking difficult. Producing short sentences only). The study thus seeks to answer the question whether SimpTell enables chronically agrammatic speakers of Dutch to use elliptical constructions more frequently and whether this brings about an increase in verbal functional communication.
Doel van het onderzoek
In chronically agrammatic speakers of Dutch, SimpTell leads to an enhancement of elliptical style which in turn improves verbal functional communication, specifically verbal efficiency.
Onderzoeksopzet
two, with a time interval of 6 weeks
Onderzoeksproduct en/of interventie
According to a treatment protocol, SimpTell will the administered for a period of 6 weeks (30 hours in total) either as:
(1) blended care (parallel in-person speech and language therapy)
2) Teletherapy (no parallel in-person speech and language therapy)
Publiek
Wetenschappelijk
Belangrijkste voorwaarden om deel te mogen nemen (Inclusiecriteria)
- Age between 16 and 75 years old
- Unilateral left hemispheric stroke
- At least 6 months post-onset (chronic stage)
- Disordered sentence production (expressive agrammatism) due to aphasia. On the 6-point scale of the subtest Spontaneous Speech of the Dutch version of the Aachen Aphasia Test (AAT; Graetz, De Bleser, & Willmes, 1992), the syntactic structure of the participant’s speech output should be rated as 1 (mostly one or two word utterances; almost no inflection forms or function words) or 2 (short, simple sentences, which are mostly syntactically incomplete; frequent absence of function words and inflected forms).
- Native speaker of Dutch
- Pre-morbidly right handed
- The participant should approve the proposed aim, which is promoting the overuse of ellipses (telegraphic style)
Belangrijkste redenen om niet deel te kunnen nemen (Exclusiecriteria)
- A history of previous stroke
- Aphasia caused by tumor or trauma
- Severe aphasia (unable to understand instructions or provide consent). This is operationalised via score on either (1) the Dutch Comprehensive Aphasia Test (CAT-NL; Visch-Brink, Vandenborre, De Smet & Marien, 2014) OR (2) the Dutch version of the Aachen Aphasia Test (AAT; Graetz, De Bleser, & Willmes, 1992). (1) CAT-NL: Subtest 9 [Comprehension of spoken sentences]: a score of 18 (out of 32) or below, and Subtest 10 [Comprehension of written sentences]: a score of 14 (out of 32) or below. (2) AAT: Subtest TB 1&2 [Comprehension of spoken language]: a score of 33 (out of 60) or below, and Subtest TB 3&4 [Comprehension of written language]: a score of 30 (out of 60) or below,
- (Even with visual aid) profound visual perceptual disorders;
- (Even with hearing aid) profound hearing deficit;
- Psychiatric or neurological disorders (other than stroke)
- Severe apraxia of speech or severe dysarthria (criterion: more than 5% unintelligible speech output).
