An interventional study of Semantically focused treatment and Phonologically focused treatment in Aphasia, Stroke and Stroke, Ischemic, sponsored by University of South Carolina. Completed at 2 sites in United States. Open to participants aged 21 Years to 80 Years. Per ClinicalTrials.gov, last updated 2022-04-28.

Stroke is the leading cause of adult disability in the United States, and aphasia is common following a stroke to the left hemisphere of the brain. Aphasia therapy can improve aphasia recover; however, very little is known about how different patients respond to different types of treatments.
The purpose of this study is to understand how the following factors influence an individual's response to aphasia treatment: 1) biographical factors (e.g., age, education, gender), 2) post-stroke cognitive/linguistic abilities and learning potential, and 3) the location and extent of post-stroke brain damage. We are also interested in understanding the kinds of treatment materials that should be emphasized in speech/language treatment.
Overall, the goal of the current research is to inform the clinical management of post-stroke aphasia by identifying factors that can predict how an individual will respond to different treatment methods.

Exclusion Criteria:
This treatment will focus on improving word finding and comprehension of information.
Behavioral: Semantically focused treatment
This treatment will focus on training speech sound production, targeting overall production abilities.
Behavioral: Phonologically focused treatment
Tasks are as follows: 1. Semantic feature analysis (SFA): For each pictured stimulus the patient is prompted to name the picture, and then to produce related words that represent features similar to the target word. 2. Semantic barrier task: The goal is for one participant (e.g., patient) to describe each card so that the other participant (e.g., clinician) can guess the picture on the card. Participants are only allowed to describe the semantic features of the target and the clinician models the kinds of cues that are allowed. 3. Verb network strengthening treatment (VNeST): This treatment targets lexical retrieval of verbs and their thematic nouns. The objective of VNeST is for the patient to generate verb-noun associates with the purpose of strengthening the connections between the verb and its uses. These are tasks used in clinical aphasia rehabilitation.
Tasks are as follows: 1. Phonological (sound) components analysis task: Participants are to name a given picture and then to identify the sound features of the target words (e.g., first sound, last sound, and rhyme). 2. Phonological production task: This tasks asks participants to sort and identify the sounds that make up a word. Various stages include identifying first sounds, last sounds, etc. Participants also work on blending sounds together to form words. 3. The phonological judgment task: A computerized presentation of verbs and nouns where participants are required to judge whether pairs of words include similar phonological features. These are tasks used in clinical aphasia rehabilitation.

Ran from Aug 2016 to primary completion in May 2021, 57 months.
Of 18 interventional studies with no phase under Aphasia, Broca, half reached primary completion within 21 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 57. This study's 57 months is above that.
