Cerebrovascular reserve (CVR), defined as the increase in cerebral blood flow (CBF)in response to a vasodilatory stimulus, is known to reflect the compensative capacity of the brain to maintain adequate blood flow in the face of decreased perfusion due to arterial stenosis. CVR dysfunction has been identified as an independent risk factor for ischemic stroke. Limb remote ischemic preconditioning （LRIC) has been suggested as a protective therapeutic modality against brain ischemia. So it is worth to detect whether LRIC can improve the CVR ability in ischemic cerebrovascular disease patients.
Two groups of subjects will be constitute: (i) patients with circumscribed brain injury (including stroke, vascular malformations, tumor or circumscribed infectious lesions) or degenerative/developmental disorders and selective cognitive disorders; (ii) healthy control subjects. The objective of this project is to evaluate specific neuropsychological deficits and apply current brain imaging techniques (anatomical, diffusion, functional, magnetic stimulation) to patients suffering from these cognitive deficits due to brain damage, in order to elucidate the brain mechanisms underlying these deficits.
We aim to make clear the impact with the mechanisms of variant pathological injuries on the outcomes of CSVD, to find independent imaging markers and establish prediction model of it.
Stroke survivors commonly have respiratory muscle weakness, swallowing disturbance, general weakness, reduced the daily living activities and short of motivation for rehabilitation. Respiratory muscle training (RMT) has been reported to improve the pulmonary function, respiratory muscle strength, exercise capacity, sensation of dyspnea and quality of life in several diseases, but rare in stroke patients. Reviewing previous reports, the protocol, intensity and duration of respiratory muscle training is still variable. Purpose: To investigate the feasibility and efficacy of respiratory muscle training on cardio-pulmonary function, swallowing function, cough function and reduction of incidence of pneumonia in post-stroke patients. Methods: A prospective, single blinded, randomized study. Consecutive patients with diagnosis of stroke will be proved by magnetic resonance image or computerized tomography. Stroke patients, aged 35-80 years old, with inspiratory muscle weakness or swallowing disturbance will be enrolled and randomly divided into control group (usual rehabilitation alone) and experimental group [inspiratory muscle training (IMT) group for patients with inspiratory muscle weakness and expiratory muscle strengthening training (EMT) for patients with swallowing disturbance]. Each patients will receive usual rehabilitation. The investigator expect that RMT will be practical for the restoration of respiratory muscle, swallowing function, cough function and voice quality, thereby reduction of the incidence of pneumonia.
Our primary aim is to investigate whether remote ischemic conditioning (RIC) as an adjunctive treatment reduce neurological impairment at 24 hours and improve long-term recovery in acute stroke patients as an adjunct to standard treatment.
To investigate the therapeutic effect of individualized treatment of antiplatelet in secondary prevention of ischemic stroke.
This study is a randomized, double-blind, placebo-controlled, multicentre, Phase 2 study, with an optional open-label extension, to evaluate the safety, tolerability, and efficacy of RPh201 in subjects with mild to moderate AD who are eligible for enrollment in this study. Subject participation will include a Screening Phase, Treatment Phase, and an Optional Open-Label Extension. The Screening Phase will be up to 4 weeks prior to randomization. At Visit 2, Subjects will be randomized 2:1 to RPh201 or placebo. The Treatment Phase will last for 6 months post-randomization, or until subject withdrawal from the study, whichever comes first. The Optional Open-Label Extension will begin once a subject has completed the Treatment Phase and has signed an informed consent form to continue on the study. The Optional Open-Label Extension will continue for 6 months, or until subject withdrawal from the study, whichever comes first.
The aim of the current protocol is to study 40 patients, each for 12 weeks, to address hypotheses related to the ability of a telerehabilitation system to (a) improve motor status and disability, (b) collect various forms of patient data from the home, (c) improve risk factor knowledge and control, and (d) assess patient compliance with home-based telerehabilitation. Patients who have returned to their home after stroke will be provided with a telehealth system and be asked to use it 6 days/week for 12 weeks, during which time subjects will use this system for daily rehabilitation therapy, assessments, and education--all on one platform.
The FLOW trial is a randomized placebo-controlled trial analyzing the effect of coupling an anti-depressant, fluoxetine (Prozac), and exercise to improve motor recovery following a stroke.
The interventional study aims to increase the knowledge on arm and hand rehabilitation after stroke within community-based services. The primary objective of the study is to evaluate the feasibility and clinical usefulness of the arm and hand training program (focusing on functional goal- and task-oriented daily life exercises) in combination with the use of an orthotic device in terms of patient compliance and improvement of outcomes. The secondary objective is to compare the effectiveness of the program with or without the use of an orthotic device in a randomized controlled trial.
