The Feasibility, Usability, and Acceptability of Using the Oculus™ Virtual Reality Gaming Technology...
StrokeThe purpose of this study is to test the (a) feasibility, (b) usability, and (c) acceptability of using the Oculus Virtual Reality (VR) for chronic stroke survivors who have mild-moderate cognitive and unilateral arm impairment to administer upper extremity and cognitive rehabilitation, to calculate the change in upper extremity and cognition scores on standardized measurements per standard of care and to qualitatively explore the impact of engaging caregivers in supporting the stroke survivor's rehabilitation and the impact of this engagement on the stroke survivor and caregiver dyad using semi-structured interviews.

Ischemic Stroke; Ischemic AttackTransientThe purpose of this study is to evaluate whether milvexian compared to placebo reduce the risk of recurrent ischemic stroke.
Efficacy of START (Startle Rehabilitation Therapy) in the Treatment Stroke-induced Aphasia/Apraxia...
StrokeAphasia1 moreA stratified, parallel-group, double-blind, randomized controlled trial of remotely delivered START treatment to individuals with severe-to-moderate stroke (with recruitment focused on individuals with low SES) will be conducted. Subjects and assessors will be blinded to the condition making the experiment double blind. Specifically, subjects will be told that we are exploring a new therapy that using different sounds to improve therapy. Parallel group design will ensure that subjects in the Control group are unaware that their "sounds" are softer than the START group. Trainers may become aware that a loud sound is present thus a unique Assessor will evaluate clinical performance before and after training making the study double-blind. Fifty-four subjects will undergo baseline testing in the laboratory to establish their capacity for functional and expressive speech as well as their self-reported health-related quality of life (power analysis below). Next, subjects will participate in a high-frequency, word-picture verification/ auditory-repetition treatment, 2 hr/day for 5 consecutive days focusing on expression of words of functional significance (e.g., water, fall). Subjects will either receive training with START or without (Control). Subjects will be re-tested immediately following training as well as one-month post to assess retention. Aim 1 will evaluate capacity of START to enhance SLT outcomes by assessing the % change in clinical assessment of functional and expressive speech. Our preliminary data points to a robust response [details]. Aim 2 will focus on the capacity of these changes to 1) be retained and 2) impact subject's reported quality of life. NOTE: While we are planning in-person baseline, end, and retention testing, in response to COVID, we have established remote clinical screening using peer-reviewed validated techniques for WAB and ABA-2 (see Alternative Solutions). All preliminary data collected for this proposal were collected remotely via no-contact protocols.
Locomotor Recovery and Compensation Post-stroke (LRC)
StrokeThe proposed research will characterize of the time course of neurological and locomotor recovery as well as development of compensatory strategies throughout sub-acute and chronic phases post stroke. In addition, we will also investigate the extent to which measures of recovery and compensation are malleable and can be altered with specific interventions in both the early and late stages post-stroke. Delineation of the time course of development and magnitude of patterns of recovery and compensation should result in alternative predictive "rules' regarding how patients early post-stroke could recovery functional and neurological function.

Brain IschemiaStroke1 moreThe aim of the biomedical research is to evaluate the changes of body position management during standing and walking for stroke patients, using innovative training methods during the rehabilitation.
Improving Early Reperfusion With Adjuvant Dornase Alfa in Large Vessel Ischemic Stroke (EXTEND-IA...
Ischemic StrokePatients presenting to the emergency department with acute ischemic stroke, who are are eligible for standard intravenous thrombolytic therapy within 4.5 hours of stroke onset will be assessed for major vessel occlusion to determine their eligibility for the trial. All participants will receive intravenous tenecteplase and endovascular thrombectomy as standard care. The trial is a Bayesian Optimised Phase 2 dose-finding umbrella trial (single arm versus objective performance criterion of 20% substantial reperfusion prior to endovascular thrombectomy based on the EXTEND-IA TNK trials NCT02388061, NCT03340493). The aim is to determine the optimal dose of intravenous dornase alfa (recombinant human DNase 1) with sufficient promise to take forward in a seamless phase 2b/3 design.
Studying Language With Brain Stimulation in Aphasia
StrokeAphasiaThe overall goal of this study is to evaluate whether stimulation of two brain areas alongside behavioral speech-language therapy increases connectivity to improve language functions in stroke-aphasia patients.
Virtually Assisted Home Rehabilitation After Acute STroke (VAST-rehab)
StrokeThe purpose of this study is to investigate the feasibility of a virtual education and virtual visit program in engaging patients with rehabilitation at home after stroke.
Cognitive Training on Sleeping Disorders in Stroke
StrokeSleep DisorderCognitive impairment and sleeping disturbance following stroke diagnosis are common symptoms that significantly affect the quality of life.
Synchronized Brain and Hand Stimulation After Stroke
StrokeUpper Extremity ParesisAmong the 795,000 individuals who sustain a stroke annually in the United States, 65% continue to experience moderate-to-severe impairments in one hand six months or more, which limits their ability to perform daily tasks. Currently there is dearth of understanding of the mechanisms of motor recovery after stroke. Understanding the mechanisms can potentially lead to the development of interventions to improve motor performance after stroke. The proposed study will examine how synchronously pairing brain and hand stimulation repeatedly affects the plasticity of the brain and motor performance after stroke. The knowledge gained from this study can be useful to develop interventions to improve hand movement after moderate-severe stroke.
