|---|---|---|---|---|
| Primary | Change in the Western Aphasia Battery Revised Aphasia Quotient | Baseline, immediately after the 10-week intervention | The Western Aphasia Battery Revised Aphasia Quotient (WAB-R-AQ) is a standardized, gold-standard assessment for determining the presence, type, and severity of post-stroke aphasia. The WAB-R measures performance across a variety of expressive and receptive language domains. Weighted performance across four of these domains, namely spontaneous speech, auditory verbal comprehension, repetition, and naming/word finding, yields the WAB-R AQ, a composite score that ranges from 0 to 100, with higher scores indicating better language function. | ClinicalTrials.gov |
| Secondary | Western Aphasia Battery- Revised Language Quotient (WAB-R LQ) | Baseline, immediately after the 10-week intervention | The WAB-R measures performance across a variety of expressive and receptive language domains and takes approximately 45-60 minutes to administer. Weighted performance across four of these domains - spontaneous speech, auditory verbal comprehension, repetition, and naming/word finding - yields a composite score, the WAB-R Aphasia Quotient (AQ). The WAB-R AQ is an impairment-based metric that reliably indexes aphasia severity across different aphasia subtypes, making it ideal as a metric for studies with heterogenous patient samples as for the current study. In addition to the AQ, Language Quotients (LQ) can be obtained from a full administration of the WAB-R. LQ is a summary score encompassing both spoken and written language abilities. The LQ is scaled from 0 to 100, where higher numbers reflect stronger overall performance across the tested domains. | ClinicalTrials.gov |
| Secondary | Western Aphasia Battery- Revised Cortical Quotient (WAB-R CQ) | Baseline, immediately after the 10-week intervention | The Cortical Quotient (CQ) is a summary score taking into account all subtests of the WAB-R, including not only spoken and written language but also apraxia, constructional, visuospatial and calculation tasks. Administration of tests to calculate CQ and LQ together take approximately 45 minutes. The CQ is scaled from 0 to 100, where higher numbers reflect stronger overall performance across the tested domains. | ClinicalTrials.gov |
| Secondary | Boston Naming Test (BNT) | Baseline, immediately after the 10-week intervention | The BNT is one of the most widely used measures of confrontational naming, consisted of 60 line drawings of objects of graded difficulty. It consists of 60 black and white pictures that increase in the order of difficulty (pictures progressively include less frequent words). Scoring comprises accuracy out of 60 items. A point is typically given for items named spontaneously or correctly after a semantic cue (a category or description hint). For healthy, non-brain-damaged adults, average raw scores generally range from 50 to 59 out of 60, depending on age and education level (with normative means clustering around 53 to 55). | ClinicalTrials.gov |
| Secondary | Pyramids and Palm Trees Test (PPTT) | Baseline, immediately after the 10-week intervention | The PPTT is a visual semantic association task designed to assess semantic memory and the ability to form and retrieve associations between concepts. For each triad, a target stimulus (e.g., a picture or word of a pyramid) is shown at the top, and two choice options (e.g., a palm tree vs. a fir tree) are shown at the bottom. The subject must point to or select the item that semantically matches the target. There are 52 trials. A score of 47 or higher (90% or better: ≥ 47/52) is generally considered normal, indicating no clinically significant semantic memory deficit. A score below 47 (less than 90%) indicates a clinically significant semantic memory impairment. | ClinicalTrials.gov |
| Secondary | Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) | Baseline, immediately after the 10-week intervention | The RBANS provides a comprehensive assessment of general cognitive skills, including attention, memory, executive function, and visuospatial processing. The battery consists of 12 short subtests divided across five specific cognitive domains: Immediate Memory: List Learning, Story Memory, Visuospatial/Constructional: Figure Copy, Line Orientation, Language: Picture Naming, Semantic Fluency, Attention: Digit Span, Coding, Delayed Memory: List Recall, List Recognition, Story Recall, Figure Recall. Reported total scores range from 40 to 160, with scores 120 or higher as superior performance. | ClinicalTrials.gov |
| Secondary | Reading Comprehension Battery for Aphasia-2 (RCBA-2) | Baseline, immediately after the 10-week intervention | The RCBA-2 provides a comprehensive evaluation of the nature and degree of reading impairments at single word-, sentence- and paragraph-level. Lower total scores indicate more severe acquired reading impairments (alexia) associated with aphasia or brain injury. Total score is 0-100 (10 core subtests), typical range is 97.32, whereas aphasic patients tend to score 18-99. | ClinicalTrials.gov |
| Secondary | Stroke and Aphasia Quality of Life Scale-39 (SAQOL-39) | Baseline, immediately after the 10-week intervention | The SAQOL-39 consists of 39 questions to assess health-related quality of life in individuals with chronic post-stroke aphasia with responses from 1 = Could not do it at all to 5 = No trouble at all. To calculate the scores, the mean (average) value rather than a cumulative sum is calculated and higher means suggest higher quality of life | ClinicalTrials.gov |
