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. @@ -275,7 +256,7 @@ 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 -"12",9,"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.

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. @@ -527,7 +508,7 @@ 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.

Aphasia impacts language production and comprehension as well as reading and writing. The ramifications of aphasia extend beyond language impairment to negatively impacting a person's social, vocational, and recreational activities. 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.

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).

It can affect an individual's ability to speak, understand spoken language, read, and write.

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).

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. @@ -1696,7 +1677,7 @@ 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 -"69",77,"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.
