Filter by:The goal of this clinical trial is to evaluate whether intra-arterial (IA) rhTNK-tPA thrombolysis can improve neurological outcomes in acute large vessel occlusion patients after successful mechanical thrombectomy (MT) recanalization between 4.5- 24 hours from symptom onset. Participants enrolled will be randomly assigned to study or control arm with a 1:1ratio. Study group will receive IA rhTNK-tPA thrombolysis (0.125 mg/kg, Max 12.5mg) plus best medical management, and control receive best medical management alone.
Objective: To investigate the incidence, clinical characteristics and prognosis of acute ischemic and hemorrhagic cerebrovascular disease secondary to the implantation of cardiovascular implantable electronic devices, so as to provide a basis for subsequent treatment strategies and risk factor stratification. Methods: This study intends to retrospectively collect the incidence and case characteristics of acute cerebral infarction, cerebral embolism, transient ischemic attack and cerebral hemorrhage in CIED patients admitted to the First Affiliated Hospital of Xi 'an Jiaotong University and other centers from January 2012 to September 2022. Then, the incidence of poor prognosis and related factors of patients within 3 months were followed up by telephone to provide a basis for subsequent treatment strategy and risk factor stratification.
Post-stroke sleep disorder and motor/cognitive dysfunction are common complications that affect the quality of life of older patients. The proposed study investigates the effects of an acupuncture-like method applied to six bilateral acupoints on sleep quality, motor function and cognition in older adults with chronic stroke. The study will be a single-blind (i.e., only patients will be blinded about the research purpose) randomized controlled trial (i.e., patients receiving the treatment is chosen at random) with a pre-mid-post follow-up design and involve two parallel groups of post-stroke survivors (aged > 55 years) diagnosed with insomnia. Participants will be randomly allocated in a 1:1 radio to two independent groups, i.e., a treatment group or placebo group, namely a transcutaneous electrical nerve stimulation placed on acupoints (Acu-TENS) or a placebo group. The Acu-TENS group will receive a 6-week treatment that includes a 30-minute Acu-TENS + sleep hygiene program (SHP) twice a week. The placebo group will receive sham Acu-TENS (i.e., devices with the electrical circuit disconnected) + SHP with the same frequency as the Acu-TENS group. The selected acupoints will be bilateral Hegu (LI4), Quchi (LI11), Neiguan (PC6), Shenmen (HT7) on the arm and Sanyinjiao (SP6) and Zusanli (ST36) on the lower limb. The study's primary outcomes will be sleep quality measured by the device of ActiGraph and the self-report survey. The secondary outcomes will be motor function, measured by physical performance tests, cognition, measured by computer battery, and quality of life, measured by the self-report survey. All outcomes will be measured at the baseline assessment (before the treatment), mid-term assessment (after the three weeks treatment), post-treatment assessment (after the six-week treatment), and follow-up assessment (two weeks after the treatment ended). It is hypothesized that the Acu-TENS + SHP treatment will better alleviate insomnia, improve cognition and motor function in participants than the sham Acu-TENS + SHP treatment.
Human development as a species has been strongly associated with the ability to dexterously manipulate objects and tools. Unfortunately, current therapy efforts typically fail to restore fine manual control after stroke. The goal of this study is to evaluate a new intervention that would combine targeted electrical stimulation of selected nerves with use a soft, pneumatically actuated hand exoskeleton to enhance repetitive practice of independent movements of the fingers and thumb in order to improve rehabilitation of hand function after stroke. The investigators will recruit stroke survivors in the subacute phase of recovery (2-9 months post-stroke). These participants will be involved in a 5-week intervention involving 15 training sessions. During these sessions, participants will train independent movement of the digits of the paretic hand. Evaluation of motor control of the paretic hand will occur prior to initiation of training, at the midpoint of the training period, after completion of training, and one month later.
To observe the safety and efficacy of intensive drug therapy for ischemic stroke patients.Patients with acute stroke caused by intracranial arterial stenosis (stenosis rate ≥70%) were enrolled and accept dual antiplatelet therapy (DAPT) (aspirin 100 mg/d and clopidogrel 75 mg/d for 90 days, followed by aspirin 100 mg/d for long term) under the guidance of platelet function analysis (Verifynow) combined with the intensive statin therapy (40 mg/d for 14 days, followed by 20 mg/d for long term).
The Smart Ankle-Foot Orthosis (Smart AFO) system is an investigational system that combines a diagnostic ankle-foot orthosis with a mobile application to assist clinicians in optimizing an AFO user's gait by adjusting AFO stiffness and range of motion settings, and quantifying functional walking improvements in post-stroke individuals. The purpose of the clinical testing is to evaluate the Smart AFO system with its target users: post-stroke AFO users and orthotists. This may include, but is not limited to, identifying any aspects of the Smart AFO system that could be improved through clinical testing and evaluating the gait of post-stroke AFO users walking with an AFO adjusted using the Smart AFO system.
This monocentric methodological study aims at optimizing advanced MR sequences for image quality (reduced artefacts, signal to noise ratio, acquisition time, stability of quantitative measurements) on a new MR unit dedicated to research in clinical and cognitive neuroscience.
The physical and social effects of exercise programs and daily exercise have already been demonstrated in stroke. However, stroke survivors have shown a passive attitude towards the exercise program and there was little guideline and experience of the stroke exercise program in the community. Therefore, the study provides patients with an adequate guide to a complex exercise program after discharge based on the medical records.
Research shows that exercising at home can improve arm and hand movement after a stroke. Unfortunately, it can be hard to exercise enough to make a difference in arm and hand movement after stroke. In this study, the investigators will try to determine things that make it easy or hard for Veterans to exercise their arm and hand after a stroke. In this study, the investigators will recruit Veteran stroke survivors who have difficulty using their arm and hand after a stroke. First, the investigators will administer surveys and questionnaires to get Veteran stroke survivors' perspectives on their self-confidence, mood, sleep, and more. Then, the investigators will ask them to track their home exercise using a wearable movement tracker (like a smart watch). Then, Veteran stroke survivors will meet with a researcher to talk about their experience doing home exercise and why they think it was easy or hard to do.
Upper limb impairment is present in more than 85% of people with stroke, which greatly affect the quality of life, social participation, and performance of daily activities of people with stroke. Previous study also revealed that 53.4% of people after stroke experienced cognitive impairment. Different cognitive domains might be affected following stroke, such as attention, memory, language, and orientation, and the problems with memory are often prominent. Yet, there is no effective treatment for the post-stroke cognitive impairment. Transcutaneous electrical nerve stimulation (TENS) applied on thoracic region and transcutaneous vagus nerve stimulation (tVNS) are simple and non-invasive treatment to improve upper limb motor function and cognitive function. However, no existing studies have explored on the effects of TENS and tVNS on cognitive function in people with stroke. Therefore, the purpose of this study is to evaluate the effectiveness of TENS on improving upper limb function and cognitive function in people with chronic stroke. Also, this study will investigate the cortical response of people with stroke during TENS by using EEG power spectrum analysis.
