Filter by:This project seeks to determine how post-stroke cognitive impairment moderates motor learning during walking in older adults with chronic stroke and identify brain structural markers that mediate this relationship. The chosen experimental design integrates biomechanical analyses, neuropsychological assessments, and brain imaging techniques to determine the impact of post-stroke cognitive impairment severity on two forms of motor learning (explicit and implicit) and examine the role of the dorsolateral prefrontal cortex in the relationship between cognition and explicit motor learning. Ultimately, this work may lead to the development of a more comprehensive, effective treatment approach to improve walking dysfunction in older adults post-stroke.
Branch atheromatous disease (BAD) has been reported to contribute to small-vessel occlusion and is associated with a higher possibility of early neurological deterioration (END). Because the pathology of BAD is due to atherosclerosis, the investigators postulate that early intensive medical treatment with dual antiplatelet therapy(DAPT) and high-intensity statin may prevent END and recurrent stroke. The investigators hypothesise that intensive medical therapy can prevent END in BAD using aspirin, clopidogrel and high-intensity statin.
More than 80% of ischemic stroke (IS) patients have some walking disability, which restricts their independence in the activities of daily living. Physical therapy (PT) significantly contributes to gait recovery in patients after IS. However, it remains unclear, what type of gait training is more effective and which factors may have impact on gait recovery. Two hundred fifty IS patients will be enrolled to undergo a 2-week intensive inpatient rehabilitation including randomly assigned robot-assisted treadmill gait training (RTGT) or therapist-assisted treadmill gait training (TTGT). A detailed clinical and laboratory assessment of gait quality, as well as the degree of neurological impairment, quality of life, cognition and depression will be performed in all patients during the study. We hypothesize that these variables may also affect gait recovery in patients after IS. In a randomly selected 60 enrolled patients, a multi-modal magnetic resonance imaging (MRI), including functional MRI, will be performed to assess neural correlates and additional predictors of gait recovery.
Previous studies of the exosuit technology have culminated in strong evidence for the gait-restorative effects of soft robotic exosuits for patients post-stroke by means of substitution for lost function. The present study builds on this work by suggesting that an exosuit's immediate gait-restorative effects can be leveraged during high intensity gait training to produce long-lasting gait restoration. Current gait training efforts are focused on either quality or intensity. They focus on gait quality often by reducing the training intensity to allow patients to achieve a more normal gait. In contrast, efforts focused on training intensity push participants without focusing on the quality of their movements. These intervention paradigms generally fail to substantially impact community mobility. In this study, the investigators posit that exosuits can uniquely enable an integration of these paradigms (ie, high intensity gait training that promotes quality of movements). For this protocol, exosuits developed in collaboration with an industry partner, ReWalk⢠Robotics will be used. To evaluate the effects of REAL gait training, the investigators will use clinical measures of motor and gait function, locomotor mechanics and energetics, and physiologic measures that may infer on motor learning. The spectrum of behavioral and physiologic data that we will collect will enable us to understand more comprehensively the gait-restorative effects of REAL.
The investigators would like to investigate the effectiveness of somatosensory training for robot-assisted hand motor rehabilitation after stroke.
To explore the safety and efficacy of edaravone dexborneol for patients of acute ischemic stroke received endovascular therapy in extended time windows.
A 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.
