The central hypothesis is that strategy training will increase patients with aphasias' explicit knowledge about circumlocution and enable them to use it to (1) self-facilitate naming, and (2) produce more informative connected speech.","Every 40 seconds, someone in the United States suffers from a stroke. Approximately 25% of stroke survivors acquire aphasia, a communication disorder that can result in a partial or total loss of spoken and written language ability, which significantly and negatively impacts quality of life and societal participation. The ability to verbally label objects, referred to as 'naming' in the literature, is impaired in all patients with aphasia. Naming is, therefore, a common focus of treatment. Naming treatments improve people with aphasias' naming ability for items that are directly trained during therapy. However, these same treatments face two critical limitations: (1) inconsistent generalization to untrained items, and (2) little to no generalization to spontaneous, connected speech. As it is impossible to train the entire universe of objects during a patient's course of therapy, generalization of gains beyond what is trained in therapy is crucial. @@ -255,7 +313,7 @@ Exclusion criteria: Experienced multiple strokes; Be in the acute stage of their aphasia, <6 months post onset of stroke; Have a diagnosis of neurodegenerative disease, significant mental illness, psychiatric disorder, drug/alcohol abuse, or neurological condition that could influence cognitive, language, and memory systems","No","18 Years","All","Boston","02129","Massachusetts","Sofia Vallila Rohter","United States",1,"no",-71.0537615,42.3756115,2021-08-30 -"11",8,"Speech Entrainment for Aphasia Recovery","Aphasia Aphasia Non Fluent Stroke","August 21, 2020","NCT04364854","Medical University of South Carolina Charleston South Carolina United States","Medical University of South Carolina","Recruiting","After a stroke, many people experience a language impairment called aphasia.

Virtual reality (VR) is an immersive and interactive computer simulation technology that can promote the ecological validity of speech therapy. In this study, we develop an innovative VR software for speech training to explore the effects of VR on various aspects of language outcomes.","We randomly assigned study participants into 2 groups: the traditional speech therapy (ST) group and the traditional ST with additional VR training (ST+VR) group. In the ST group, each participant received 1-hour traditional ST for each session. In the ST+VR group, an additional 30-minute VR training was administered immediately after each session of traditional ST. All participants received 3 sessions of treatment every week for 3 weeks. For outcome measurement, we administered Concise Chinese Aphasia Test (CCAT) at 3 different time points: before treatment, 1 day and 3 months after the completion of treatment.","virtual reality aphasia language rehabilitation stroke","Interventional","Inclusion Criteria: Diagnosis of stroke with aphasia, including fluent and non-fluent types Age between 20~80-year-old @@ -383,7 +441,7 @@ Unable to learn how to use the virtual reality controller and device Any medical diseases or unstable vital signs that may cause safety concern Severe hearing or vision impairments Have ever received any form of speech therapy or virtual reality training","No","20 Years","All","Taipei city",NA,NA,NA,"Taiwan",1,"no",121.519937,25.1193725,2022-04-07 -"17",13,"Efficacy of Low-frequency rTMS in Aphasia","Aphasia","July 18, 2022","NCT05450341","Medipol University Istanbul NA Turkey","Medipol University","Recruiting","In a randomized controlled trial, efficacy of low-frequency, inhibitory rTMS will be examined in rehabilitation of acquired aphasia.

For PWA, the ability to access words can change day-to-day and even minute-to-minute, resulting in diminished motivation to participate in conversations, disengagement from social interactions, and reduced quality of life. Per psycholinguistic models of lexical access, naming is a two-step process that involves retrieval of the target's meaning from the semantic system and word form (speech sounds) from the phonological system. Naming failures in PWA result in errors that are related to a target word in meaning (e.g., ""carrot"" for bean), word form (e.g., ""fean"" for bean), both meaning and form (e.g., ""green"" for bean), or neither (e.g., ""pencil"" for bean; ""I know it but I can't say it"" for bean) due to insufficient activation of the target meaning/form representations or overactivation of incorrect representations. Due to this noisy system, lexical access is often delayed in PWA, even when the correct word is eventually retrieved. Naming accuracy, response times, and error types provide meaningful information regarding the locus of naming impairment and a patient's recovery capacity. The investigators found that the number of phonological and unrelated errors produced during early post-stroke stages predicted longitudinal changes in naming and global language skills in left hemisphere stroke survivors. Naming errors and the integrity of underlying semantic and phonological systems can also guide language treatment planning. As such, accurate assessment of naming is critical for aphasia care. @@ -536,7 +594,7 @@ Presence of aphasia Exclusion Criteria: History of neurological disease affecting the brain other than stroke","No","18 Years","All","Boston","02115","Massachusetts",NA,"United States",1,"no",-71.0883555,42.3397355,2022-12-19 -"24",22,"Semantic Feature Analysis Treatment for Aphasia","Aphasia","February 24, 2020","NCT04215952","VA Pittsburgh Healthcare System Pittsburgh Pennsylvania United States","VA Pittsburgh Healthcare System","Recruiting","This randomized controlled comparative effectiveness study examines manipulation of a key component of an established and efficacious treatment for naming impairments in aphasia, along with cognitive and brain correlates of treatment success.

Currently, the most effective way to treat aphasia is with speech-language therapy (SLT). However, even if SLT is intensive, persons with aphasia are left with residual language delays. Recent research suggests that pairing SLT with transcranial direct current stimulation (tDCS) a non-invasive, safe, low-cost form of brain stimulation may aid language recovery in persons with aphasia. However, results from tDCS studies are inconclusive. The success of tDCS in combination with SLT could depend on the timing of tDCS since tDCS-induced effects depend on the neuronal state of the brain-networks at the time of the stimulation. In this study, the differential impact of tDCS before behavioral SLT (offline-before therapy), tDCS after SLT (offline-after therapy), and tDCS concurrently with SLT (online) on functional language recovery in persons with aphasia will be investigated. Sham tDCS (i.e., SLT alone) as a control group will also be included in the study.

This proof-of-concept study is the first to evaluate the direct effect of speech entrainment practice on independent speech. Thus, the effect size for accurate power estimation is not known. The strategy for this study is to optimize experimental sensitivity by maximizing the number of observations per participants per condition within the constraints of feasibility. The results from this study will provide critical information for evaluating the effect size for a subsequent phase. Nevertheless, to estimate an optimal sample size, the investigators leveraged the data from our Pilot Study, which examines the speech entrainment effect on immediate performance rather than learning. With 13 participants, the investigators estimated 80% power to detect the effect of 0.8 (mean difference between groups divided by the pooled standard deviation) observed in our pilot study for speaking with audiovisual speech entrainment vs. independent speech (Aim 1). The calculation is based on a paired t-test with an alpha of .05 (two-tailed) and a correlation of 0.5 between groups. With 24 participants, there is 80% power to detect the observed effect of 0.6 for speaking with audiovisual speech entrainment vs. auditory-only speech entrainment (alpha is set to .05, two-tailed, correlation between groups is .57; Aim 2b). The investigators have substantially increased the sample size (N=40) with the consideration that learning effects (the focus of the present study) are expected to be smaller than performance effects (the focus of the Pilot Study).","","Interventional","Inclusion Criteria: @@ -1109,7 +1185,7 @@ Exclusion Criteria: History of learning disabilities History of other comorbid neurological impairments","No","18 Years","All","Elkins Park","19027","Pennsylvania","Marja-Liisa Mailend, PhD","United States",1,"no",-75.120418,40.035597,2023-01-25 -"46",51,"Links Between Motor Abilities and Language Ability Deficits in Patients With Post-stroke Aphasia","Stroke Aphasia","May 26, 2023","NCT05776368","Hospices Civils de Lyon Bron Cedex NA France","Hospices Civils de Lyon","Recruiting","Aphasia is a language disorder that affects oral and written expression and/or comprehension.

It can affect an individual's ability to speak, understand spoken language, read, and write. Many treatments designed to improve spoken language in persons with aphasia (PWAs) use unison speech, having the person with aphasia speak along with the clinician or with a recording. One goal of this study is to determine who benefits from speaking in unison, and what characteristics of speech help them the most. Another goal is to investigate a possible mechanism for this benefit: why does speaking in unison help? This knowledge is important because understanding who benefits from this commonly used and potentially powerful therapy component, under which conditions they benefit, and why they do, is critical for customizing therapy so it can be as effective and efficient as possible. Unison speech is conducted using one of two different timing patterns: (1) a natural conversational pattern, which is used in everyday conversations, or (2) a metrical pattern, which follows a beat-based timing framework, as in songs or some poems. In either case, precisely aligning one's speech with that of another person (i.e., entraining one's speech) requires prediction: each speaker must plan their own speech motor commands before having heard the other speaker say the words they are planning. Natural conversational timing requires the speaker to make use of knowledge about language, particularly grammar, to align with the other person. In contrast, a metrical pattern allows a speaker to predict speech timing without relying heavily on language-based knowledge. Given that many PWAs have impaired grammar, we hypothesize that most PWAs will benefit more from speaking in unison to sentences with metrical vs. conversational timing patterns. However, there is great variation in linguistic, motor speech, and timing skills across PWAs, so metrical and conversational timing patterns are likely to have different degrees of effectiveness for different individuals. Results from this study will demonstrate how individual characteristics and speech timing affect whether or not a person with aphasia benefits from speaking in unison.

While language rehabilitation can yield improved language functioning, treatment outcomes vary greatly across individuals. In chronic aphasia, language gains occur through the brain's inherent ability to reorganize (i.e., neuroplasticity). While Speech-language therapy (SLT) can target various language skills and modalities, the most pervasive deficit across all persons with aphasia (PWA) is difficulty with word finding. Thus, aphasia treatment often includes some form of intervention focused on improving naming abilities. As with language function in general, naming abilities in PWA seems to be associated with left hemisphere recruitment, particularly with the viable tissue at the rim of the lesion (perilesional areas). This project investigates an innovative approach to improving current therapy by examining the benefits of using excitatory transcranial direct current stimulation (tDCS) stimulation/neuromodulation during anomia treatment (i.e. word-finding treatment). @@ -1848,7 +1924,7 @@ Co-occurring history of neurological disease/disorder/injury (e.g., traumatic br Co-occurring history of a major mental illness (e.g., schizophrenia, drug addiction, bipolar) Clinical conditions contraindicated for MRI or tDCS (e.g., implanted electrical devices, claustrophobia, seizure disorder) Positive pregnancy test (for females)","No","18 Years","All","Little Rock","72205","Arkansas",NA,"United States",1,"no",-92.3396525,34.7224165,2019-09-03 -"74",73,"Transcranial Alternating Current Stimulation (tACS) in Aphasia","Aphasia Stroke","January 4, 2020","NCT04375722","Medical College of Wisconsin Milwaukee Wisconsin United States","Medical College of Wisconsin","Recruiting","This study will assess the effects of transcranial alternating current stimulation (tACS) on language recovery after stroke as well as healthy language functions.","Aphasia is a debilitating disorder, typically resulting from damage to the left hemisphere, that can impair a range of communication abilities, including language production and comprehension, reading, and writing.

But enhancing language recovery early after stroke is desirable because of its potential impact on long-term language outcomes and quality-of-life. The current study will investigate the efficacy of high-definition tACS (HD-tACS) to help restore neural oscillatory activity in aphasia. TACS differs from tDCS in that sinusoidal, alternating currents are delivered rather than constant currents. TACS can manipulate the ongoing oscillatory neuronal activity and potentially increase functional synchronization (or connectivity) between targeted areas. This feature of tACS is quite attractive, given the new body of evidence suggesting that language impairments stem from diminished functional connectivity and disruptions in the language network due to stroke. The selection of tACS frequencies in this study is guided by our preliminary work examining pathological neural oscillations found near stroke-lesioned areas (or perilesional) in aphasia. By exogenously tuning the perilesional oscillations with tACS, the investigators hope to up-regulate communication across these areas and other connected areas to improve language outcome. If successful, tACS will be a powerful and novel treatment approach with reverberating positive impact on long-term recovery. @@ -1880,7 +1956,7 @@ Any metal implants in the skull Contraindications to MRI or tACS History of seizures History of dyslexia or other developmental learning disabilities","Accepts Healthy Volunteers","18 Years","All","Milwaukee","53226","Wisconsin","Priyanka Shah-Basak, PhD","United States",1,"no",-88.022002,43.04338,2020-01-04 -"75",78,"Treatment of Grammatical Time Marking in Post-Stroke Aphasia","Brain Injury, Vascular Aphasia Stroke","December 30, 2022","NCT05656638","University of Neuchatel Neuchâtel NA Switzerland","University of Neuchatel","Recruiting","The study aims to assess a individual or group therapy's effectiveness in grammatical time marking.

TACS is shown to manipulate ongoing oscillatory brain activity and also to modulate synchronization (or connectivity) between targeted brain areas. This feature of tACS is quite attractive, given the new body of evidence suggesting that language impairments stem from diminished brain connectivity and ensuing disruptions in the language network due to stroke. @@ -2032,7 +2108,7 @@ The presence of cardiac stimulators or pacemakers Contraindications to MRI or tACS, e.g. patients with metallic implants, and/or history of skull fractures, pregnancy, skin diseases History of ongoing or unmanaged seizures History of dyslexia or other developmental learning disabilities","No","18 Years","All","Milwaukee","53226","Wisconsin","Priyanka Shah-Basak, PhD","United States",1,"no",-88.022002,43.04338,2023-09-20 -"84",99,"Brain-based Understanding of Individual Language Differences After Stroke","Aphasia Stroke Alexia","November 1, 2018","NCT04991519","Georgetown University Washington District of Columbia United States","Georgetown University","Recruiting","Strokes often cause a loss of communication ability, referred to as aphasia, as well as cognitive difficulties.

The central hypothesis is that strategy training will increase patients with aphasias' explicit knowledge about circumlocution and enable them to use it to (1) self-facilitate naming, and (2) produce more informative connected speech.","Every 40 seconds, someone in the United States suffers from a stroke. Approximately 25% of stroke survivors acquire aphasia, a communication disorder that can result in a partial or total loss of spoken and written language ability, which significantly and negatively impacts quality of life and societal participation. The ability to verbally label objects, referred to as 'naming' in the literature, is impaired in all patients with aphasia. Naming is, therefore, a common focus of treatment. Naming treatments improve people with aphasias' naming ability for items that are directly trained during therapy. However, these same treatments face two critical limitations: (1) inconsistent generalization to untrained items, and (2) little to no generalization to spontaneous, connected speech. As it is impossible to train the entire universe of objects during a patient's course of therapy, generalization of gains beyond what is trained in therapy is crucial. @@ -255,7 +313,7 @@ Exclusion criteria: Experienced multiple strokes; Be in the acute stage of their aphasia, <6 months post onset of stroke; Have a diagnosis of neurodegenerative disease, significant mental illness, psychiatric disorder, drug/alcohol abuse, or neurological condition that could influence cognitive, language, and memory systems","No","18 Years","All","Boston","02129","Massachusetts","Sofia Vallila Rohter","United States",1,"no",-71.0537615,42.3756115,2021-08-30 -"11",8,"Speech Entrainment for Aphasia Recovery","Aphasia Aphasia Non Fluent Stroke","August 21, 2020","NCT04364854","Medical University of South Carolina Charleston South Carolina United States","Medical University of South Carolina","Recruiting","After a stroke, many people experience a language impairment called aphasia.

In this approach, since anomic deficits are often due to a weak link between the meaning of the word and its lemma, the Hebbs' principles of coincident and correlated learning can be exploited, i.e., by intensifying the synchronous activation of lexicon and semantics and connecting them with the motor counterpart.

According to the Embodied Cognition approach (EC), language is tightly connected to the motor system. In this view, language rehabilitation programs should stimulate language through the activation of the motor system. In this approach, since anomic deficits are often due to a weak link between the meaning of the word and its lemma, the Hebbs' principles of coincident and correlated learning can be exploited, i.e., by intensifying the synchronous activation of lexicon and semantics and connecting them with the motor counterpart. In this study, the investigators present an innovative training, based on the EC framework, in which they will make use of new technologies for anomia rehabilitation in post-stroke patients. Specifically, the researchers will use immersive 360° videos representing everyday actions displayed from the first-person point of view, experienced through a head-mounted display. The training will be administered 3 times a week for 4 weeks. The control group will watch standard videos representing the same actions recorded from the third-person perspective. Naming abilities will be tested before and after the training together with other cognitive and psychological measures.

For the two million Americans currently living with aphasia, word retrieval difficulties are far more severe and pervade all communication attempts. Anomia severity ranges between PWA, from mild difficulties such as delayed retrieval of low frequency words (e.g., amulet) to severe difficulty retrieving the names of even common objects (e.g., bed).

For PWA, the ability to access words can change day-to-day and even minute-to-minute, resulting in diminished motivation to participate in conversations, disengagement from social interactions, and reduced quality of life. Per psycholinguistic models of lexical access, naming is a two-step process that involves retrieval of the target's meaning from the semantic system and word form (speech sounds) from the phonological system. Naming failures in PWA result in errors that are related to a target word in meaning (e.g., ""carrot"" for bean), word form (e.g., ""fean"" for bean), both meaning and form (e.g., ""green"" for bean), or neither (e.g., ""pencil"" for bean; ""I know it but I can't say it"" for bean) due to insufficient activation of the target meaning/form representations or overactivation of incorrect representations. Due to this noisy system, lexical access is often delayed in PWA, even when the correct word is eventually retrieved. Naming accuracy, response times, and error types provide meaningful information regarding the locus of naming impairment and a patient's recovery capacity. The investigators found that the number of phonological and unrelated errors produced during early post-stroke stages predicted longitudinal changes in naming and global language skills in left hemisphere stroke survivors. Naming errors and the integrity of underlying semantic and phonological systems can also guide language treatment planning. As such, accurate assessment of naming is critical for aphasia care. @@ -536,7 +594,7 @@ Presence of aphasia Exclusion Criteria: History of neurological disease affecting the brain other than stroke","No","18 Years","All","Boston","02115","Massachusetts",NA,"United States",1,"no",-71.0883555,42.3397355,2022-12-19 -"24",22,"Semantic Feature Analysis Treatment for Aphasia","Aphasia","February 24, 2020","NCT04215952","VA Pittsburgh Healthcare System Pittsburgh Pennsylvania United States","VA Pittsburgh Healthcare System","Recruiting","This randomized controlled comparative effectiveness study examines manipulation of a key component of an established and efficacious treatment for naming impairments in aphasia, along with cognitive and brain correlates of treatment success.

Participants will receive 10 weeks of computer-based training per condition, with probes administered at baseline and at 1 week, 3 months, and 6 months post-treatment. Condition order will be randomly assigned and counter-balanced across participants. In total, Study 2 will include two initial assessment sessions, 30 one-on-one treatment sessions, 96 independent practice sessions, and 24 baseline and follow-up probe sessions per participant over a 1-year period. All assessment, treatment, and probe sessions will take place via telehealth. + +Treatment description: For each condition, all treatment procedures will be matched except for the number of treated words and the trial spacing manipulation. The treatment phase will consist of two weeks of one-on-one treatment twice per week in which the treating clinician will ensure participants know how to use the treatment web app and complete each step of flashcard practice with complete independence, followed by 8 weeks of combined synchronous/asynchronous telepractice, in which the participant will work with the treating clinician once per week and practice an additional 4 days a week for 30 minutes a day between sessions. To carefully control dosage between treatment conditions, all independent practice sessions will be logged and proctored by a student research assistant. In-person treatment sessions will each last 45 minutes to approximate realistic treatment dosage in outpatient or home health practice settings. Treatment will consist of effortful retrieval practice: on each trial, participants will see a picture of the target and attempt to name it, then press ""show answer"" to see and hear the target in verbal and written form. They will then rate their naming accuracy by button press. If they are unable to name the word correctly, they will be trained to replay the answer and repeat it 3 times prior to moving on to the next trial, per Conroy et al.","","Interventional","Inclusion Criteria: + +Existing diagnosis of chronic (>6 months) aphasia subsequent to left hemisphere stroke. +Impaired performance on 2/8 sections of the Comprehensive Aphasia Test. +Must have access to a high-speed internet connection and be able to participate in telehealth. + +Exclusion Criteria: + +History of other acquired or progressive neurological disease. +Significant language comprehension impairments (per performance on the CAT - individuals will be excluded if their spoken language comprehension mean modality T- score on the CAT falls below 40). +Unmanaged drug / alcohol dependence. +Severe diagnosed mood or behavioral disorders that require specialize mental health interventions.","No","18 Years","All","Pittsburgh","15260","Pennsylvania","William Evans","United States",1,"no",-79.958065,40.44047,2023-09-21 +"42",38,"Modulating Intensity and Dosage of Aphasia Scripts","Aphasia","September 21, 2020","NCT04138940","Shirley Ryan AbilityLab Chicago Illinois United States","Shirley Ryan AbilityLab","Recruiting","The purpose of this study is to evaluate how changing conditions of speech-language treatment (namely, amount of repetition and distribution of practice schedule) affects the language outcome of participants with aphasia following a stroke.

Yet, treatment intensity is a complex construct and information on the variables modulating it remain ambiguous and limited. Studies reported in the neuroscience and clinical literature support the need for intensive treatment to induce long-term neuroplastic changes while the cognitive psychology literature suggests that learning is best maintained with distributed schedules. A few studies have looked at dose parameters for single word naming tasks, but there is limited evidence regarding dose parameters for treatments that focus on training the production of larger units, such as sentences or even connected discourse. One approach that is frequently used clinically and has evidence for its efficacy is script training. Little is currently known regarding the optimum dose of script training (i.e., the number of repetitions over time of each sentence within the script) that is required to promote the best outcomes. This study investigates the effects of modulating stimulus variables, specifically stimulus practice distribution and stimulus repetition. We use a baseline script treatment that has experimental support regarding its efficacy, and that allows the manipulation of these variables. To ensure independence and fidelity, treatment is provided in a controlled computer environment (desktop and tablet). To avoid clinician-related variables such as expertise and personality factors that may influence treatment, sentences are modeled during treatment by an anthropomorphic agent with high visual speech intelligibility and affective expressions. @@ -964,7 +1040,7 @@ Exclusion Criteria: Any other neurological condition (other than cerebral vascular disease) that could potentially affect cognition or speech, such as Parkinson's Disease, Alzheimer's Dementia, traumatic brain injury Any significant psychiatric history prior to the stroke, such as severe major depression or psychotic disorder requiring hospitalization; subjects with mood disorders who are currently stable on treatment will be considered Active substance abuse","No","21 Years","All","Chicago","60611","Illinois","Leora Cherney","United States",1,"no",-87.618428,41.893889,2020-09-21 -"40",37,"High Definition Transcranial Alternating Current Stimulation (HD-tACS) for Post-stroke Aphasia","Transcranial Alternating Current Stimulation Post-stroke Aphasia Functional Magnetic Resonance Imaging","March 18, 2021","NCT05502822","Anhui Medical University Hefei NA China","Anhui Medical University","Recruiting","To investigate the intervention effect of high definition transcranial alternating current stimulation(HD-tACS) in chronic post-stroke aphasia and its underlying neural mechanism by MRI.","Aphasia is one of the most frequent cognitive deficits in poststroke survivor.

But enhancing language recovery early after stroke is desirable because of its potential impact on long-term language outcomes and quality-of-life. The current study will investigate the efficacy of high-definition tACS (HD-tACS) to help restore neural oscillatory activity in aphasia. TACS differs from tDCS in that sinusoidal, alternating currents are delivered rather than constant currents. TACS can manipulate the ongoing oscillatory neuronal activity and potentially increase functional synchronization (or connectivity) between targeted areas. This feature of tACS is quite attractive, given the new body of evidence suggesting that language impairments stem from diminished functional connectivity and disruptions in the language network due to stroke. The selection of tACS frequencies in this study is guided by our preliminary work examining pathological neural oscillations found near stroke-lesioned areas (or perilesional) in aphasia. By exogenously tuning the perilesional oscillations with tACS, the investigators hope to up-regulate communication across these areas and other connected areas to improve language outcome. If successful, tACS will be a powerful and novel treatment approach with reverberating positive impact on long-term recovery. @@ -1880,7 +1956,7 @@ Any metal implants in the skull Contraindications to MRI or tACS History of seizures History of dyslexia or other developmental learning disabilities","Accepts Healthy Volunteers","18 Years","All","Milwaukee","53226","Wisconsin","Priyanka Shah-Basak, PhD","United States",1,"no",-88.022002,43.04338,2020-01-04 -"75",78,"Treatment of Grammatical Time Marking in Post-Stroke Aphasia","Brain Injury, Vascular Aphasia Stroke","December 30, 2022","NCT05656638","University of Neuchatel Neuchâtel NA Switzerland","University of Neuchatel","Recruiting","The study aims to assess a individual or group therapy's effectiveness in grammatical time marking.

    +Adaptive Trial Scheduling in Naming Treatment for Aphasia +

    +
    +Principle Investigator: William Evans +
    +
    +Institution: University of Pittsburgh +
    +
    +Country: United States +
    +
    +City: Pittsburgh, Pennsylvania +
    +
    +Brief Description: +
    +

    Aphasia is a language disorder caused by stroke and other acquired brain injuries that affects over two million people in the United States and which interferes with life participation and quality of life. Anomia (i.e., word- finding difficulty) is a primary frustration for people with aphasia. Picture-based naming treatments for anomia are widely used in aphasia rehabilitation, but current treatment approaches do not address the long-term retention of naming abilities and do not focus on using these naming abilities in daily life. The current research aims to evaluate novel anomia treatment approaches to improve long-term retention and generalization to everyday life.

    +This study is one of two that are part of a larger grant. This record is for sub-study 2, which will evaluate the benefits of adaptive trial spacing. +
    +
    +Inclusion Criteria: +
    +
  • +Existing diagnosis of chronic (>6 months) aphasia subsequent to left hemisphere stroke. +
  • +Impaired performance on 2/8 sections of the Comprehensive Aphasia Test. +
  • +Must have access to a high-speed internet connection and be able to participate in telehealth.
    +
    • +Exlcusion Criteria: +
    +
  • +History of other acquired or progressive neurological disease. +
  • +Significant language comprehension impairments (per performance on the CAT - individuals will be excluded if their spoken language comprehension mean modality T- score on the CAT falls below 40). +
  • +Unmanaged drug / alcohol dependence. +
  • +Severe diagnosed mood or behavioral disorders that require specialize mental health interventions. +
