And if these changes can be related to neuroplastic change in the cerebellar cortical pathway indirectly measured through neurophysiologic changes using spectral electroencephalogram (EEG). The initial phase includes the proposed pilot study data from which will be used to inform a larger clinical trial. The primary aims of this pilot are to 1) determine the effect of combining cerebellar tDCS with constraint-induced language therapy (CILT) on language as measured by a verbal fluency task and discourse task in a small population and 2) identify the tolerance of the intervention and barriers to participation measured by the adverse events questionnaire that will inform the methodology of a larger study. The secondary aims include estimating the size of the treatment effect on 1) delta percentage in F3, F7 and Fp1 compared to F4, F8, and Fp2 using resting state EEG spectral analysis and coherence, 2) working memory as measured by the score on the n-back test and 3) quality of life as measured by the Stroke Aphasia Quality of Life survey tool. The secondary aims will be used to determine the utility of these measures in a larger clinical trial. - -This is a prospective, crossover study, sham-controlled intervention study with two intervention conditions delivered across 6 intervention sessions (3x/week for two weeks) with a 4-week washout in between. Conditions include: 1) sham cerebellar tDCS and 2) real cerebellar tDCS delivered at 2mA across 20 minutes. Each of these will be delivered during CILT intervention with a licensed, certified speech-language pathologist trained in CILT. Once tDCS stimulation has ended, CILT will continue to be delivered for an additional 25 minutes. Assessments of discourse, verbal fluency, working memory and EEG spectral analysis will be conducted at four timepoints, before and after each intervention phase.","This is a prospective sham-controlled, cross-over design. Eligible participants must be over the age of 18 years, be > least 6 months post unilateral cortical stroke and diagnosed with mild to moderate non-fluent aphasia. Additional inclusion/exclusionary criteria have been specified in and approved by the IRB. Six to seven participants are expected to be recruited and screened, with the goal to enroll and complete the study with four individuals who will be randomly assigned to receive either sham or real condition first. The two intervention conditions include: 1) andodal tDCS (2mA) to the right posterior-lateral cerebellum and 2) sham tDCS to the right posterior-lateral cerebellum. The participants will receive 20 minutes of tDCS (sham or real) during CILT followed by an additional 25 minutes of CILT alone. Each condition will be administered 3 days per week for two weeks for a total of 6 intervention sessions with a 4-week washout period between. - -For tDCS (TCT-Research Version tDCS Stimulator, Hong Kong), two 5x5 saline-soaked sponge electrodes will be used with the anode placed over the right cerebellar hemisphere; 1cm under and 4cm lateral of the inion targeting the posterior lateral cerebellum and the cathode will be placed on the right shoulder. The electrode placement will be the same across both conditions.

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.

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. @@ -1770,7 +1747,7 @@ 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 -"71",79,"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.

This is because a large cortical network is involved in language processes and, therefore, the same language disorder may result from lesions at different locations in this network. @@ -1979,7 +1944,7 @@ Impaired alertness or delirium Severe co-morbidity affecting speech Contraindication to tDCS: pregnant women, patients with active implants such as pacemakers or cochlear implants, patients with one or more seizures, metal objects in the brain Occurrence of a new stroke during the study protocol.","No","18 Years","All","Geneva","1211","GE","Adrian Guggisberg","Switzerland",1,"no",6.1486155,46.1937405,2022-10-24 -"83",110,"Prism Adaptation in Left Brain Stroke","Aphasia Spatial Neglect Stroke","February 15, 2021","NCT04387162","VA Office of Research and Development Decatur Georgia United States","VA Office of Research and Development","Recruiting","Of the 15,000 Veterans who are hospitalized for stroke each year more than half experience spatial and motor impairments and pain.

-The long-term goal of this work is to determine if combining a highly intensive, task-specific behavioral language intervention with modulation of the efferent cerebellar-cortical pathway using transcranial direct current stimulation (tDCS) has a positive influence on discourse, verbal fluency and working memory in individuals with non-fluent aphasia after stroke. And if these changes can be related to neuroplastic change in the cerebellar cortical pathway indirectly measured through neurophysiologic changes using spectral electroencephalogram (EEG). The initial phase includes the proposed pilot study data from which will be used to inform a larger clinical trial. The primary aims of this pilot are to 1) determine the effect of combining cerebellar tDCS with constraint-induced language therapy (CILT) on language as measured by a verbal fluency task and discourse task in a small population and 2) identify the tolerance of the intervention and barriers to participation measured by the adverse events questionnaire that will inform the methodology of a larger study. The secondary aims include estimating the size of the treatment effect on 1) delta percentage in F3, F7 and Fp1 compared to F4, F8, and Fp2 using resting state EEG spectral analysis and coherence, 2) working memory as measured by the score on the n-back test and 3) quality of life as measured by the Stroke Aphasia Quality of Life survey tool. The secondary aims will be used to determine the utility of these measures in a larger clinical trial.
-This is a prospective, crossover study, sham-controlled intervention study with two intervention conditions delivered across 6 intervention sessions (3x/week for two weeks) with a 4-week washout in between. Conditions include: 1) sham cerebellar tDCS and 2) real cerebellar tDCS delivered at 2mA across 20 minutes. Each of these will be delivered during CILT intervention with a licensed, certified speech-language pathologist trained in CILT. Once tDCS stimulation has ended, CILT will continue to be delivered for an additional 25 minutes. Assessments of discourse, verbal fluency, working memory and EEG spectral analysis will be conducted at four timepoints, before and after each intervention phase. -| -Sharyl Samargia-Grivette, PhD - | -|
