Filter by:The goal of this clinical trial is to test the effects of recursive self-feedback procedures on spontaneous speech production in stroke survivors with impaired speech production (aphasia). The main question it aims to answer is: • To what extent can stroke survivors with aphasia use their self-feedback alone to improve their spontaneous speech production? Participants will be engaged in the following activities: - They will perform language and cognitive tasks. - Afterwards, they will receive treatments using tablets and headphones at no cost to them. - The experimental treatments (recursive self-feedback procedures) entails responding to prompts, listening to playbacks of their speech response and attempt to minimize/correct the errors in the next attempt. This process will be repeated multiple times per prompt. - The experimental treatments are two: an adaptive version that adapts the complexity of the treatment prompt and a non-adaptive version that does not adapt task complexity. - Researchers will compare the experimental treatments to see if both have similar effects on improving spontaneous speech production.
The goal of this Interventional Study is to develop and test the Indian Adaptation of Melodic Intonation Therapy (MIT) for Indian patients in with post-stroke Non-Fluent Aphasia (PSNFA). The main question[s] it aims to answer are: • To develop the MIT Indian Adaptation tool and check its feasibility • To compare the MIT with standard speech rehabilitation in patient with PSNFA. Participants will undergo Speech Rehabilitation according to the developed module and the standard treatment will be given in the comparator arm. The speech recovery at 12 weeks will be compared in both treatment arms.
The investigators will use 3D freehand ultrasound to investigate changes in muscle morphology of the paretic m. rectus femoris and m. gastrocnemius medialis during the first 3 months after stroke. Additionally, 2D ultrasound and surface EMG will be synchronized to examine muscle activation and morphological changes resulting from this activation. Clinical tests will be conducted on the same test occasions to objectify lower limb impairment and gait recovery. As such, the investigators will explore the relationship between the muscle specific changes and functional recovery.
This domain has a prospective, randomized, controlled, open-label, parallel group with blinded endpoint assessment (PROBE) design. Up to 4,000 patients with presumed acute ischemic stroke (AIS) will be followed for 90 days (or until death, if prior to 90 days). The end of the trial is defined as the date that all participants have completed their Day 90 assessment. This domain aim is to efficiently, reliably, and simultaneously, determine the comparative effectiveness of intravenous thrombolysis (IVT) using standard-dose intravenous tenecteplase (0.25 mg/kg body weight), vs. low-dose intravenous tenecteplase (0.18 mg/kg body weight) in all patients who present to hospital with acute ischemic stroke and are considered for intravenous thrombolysis. In addition, this domain also seeks to study standard-dose intravenous tenecteplase (0.25 mg/kg body weight), vs. low-dose intravenous tenecteplase (0.18 mg/kg body weight) vs. no TNK upfront with rescue IA TNK if necessary (in those eligible for emergency EVT) and no TNK upfront in those who have taken DOACs during the preceding 24 hours. This domain therefore seeks to generate more robust randomized evidence to guide clinicians in their decisions over the balance of risks and treatment with intravenous thrombolysis with tenecteplase wherever such evidence is currently insufficient. This domain will currently evaluate four research questions in relation to the use of IVT with tenecteplase: 1. In patients with recent (24 hours) intake of a standard-dose direct oral anticoagulant (DOAC), how should IVT be used? - Use standard-dose (0.25 mg/kg body weight) or low-dose tenecteplase (0.18 mg/kg) or not at all. 2. In patients planned to be treated with endovascular thrombectomy, how should tenecteplase be used? -Treat with IV tenecteplase (standard- or low-dose) or not at all. 3. In any patient receiving IVT, what is the optimal dose of tenecteplase? - use standard-dose (0.25 mg/kg body weight) or low-dose tenecteplase (0.18 mg/kg). 4. To what extent is the treatment effect of standard- vs. low-dose tenecteplase modified by key patient characteristics, such as diabetes, prior antiplatelet therapy, renal failure, or frailty, old age or having a heavy burden of cerebral small vessel disease on brain imaging.
The CHANCE-4 study is a multicenter, double-blind, double-simulation, randomized controlled study. In patients at high-risk for mild ischemic stroke or transient ischemic attack with symptomatic intracranial artery stenosis within 24 hours of onset, we will examine whether treatment with tirofiban for 48 hours reduce the risk of ischemic stroke recurrence within 90 days compared with placebo.
Early antiplatelet therapy is promising for further improvement of functional prognosis on the basis of intravenous thrombolytic therapy. The primary purpose of this multicenter, randomized, double-blind, placebo-parallel controlled trial is to evaluate the efficacy and safety of the early dual antiplatelet therapy (within 6 hours of onset ) of ticagrelor with aspirin combined with intravenous thrombolysis in improving good functional outcome (mRS score 0-1) at 90 days inpatients with ischemic stroke.
The objective of this clinical trial is to investigate the effectiveness and safety of repetitive transcranial magnetic stimulation (rTMS) in the cerebellum for individuals with post-stroke cognitive impairment. Participants will undergo rTMS in the cerebellar hemisphere opposite the lesion site, once daily for a total of five days.
The aim of this study is to test the efficacy of the CE-marked wearable system Stroke Alarm to identify the onset of a stroke with unilateral arm motor deficit within 3 hours of onset. This is a multicenter, prospective observational single-arm trial with a registry-based propensity matched control population. A total of 500 patients will be included in the trial. An interim analysis will determine if the stroke onset frequency is sufficient to determine the main outcome. Should the number of stroke events differ from what is expected at interim analysis, study enrollment will continue to increase cohort size. Patients who meet the criteria for participation will, after signing consent, be included and receive the Stroke Alarm bracelets that are used for 3 months. Study data will be collected as baseline at inclusion, at follow-up 3 months after inclusion and by using national Swedish registry data after completion of the study. Patients with elevated stroke risk according assessed by presence of specific criteria associated with elevated risk caused by: 1. recent TIA, OR 2. recent stroke without persisting arm motor deficit, OR 3. atrial fibrillation A control population matched for age, sex, NIHSS score and health care region will be identified in the Swedish national stroke registry, Riksstroke, and used for comparison. The combined efficacy goal is at least 60% sensitivity for Stroke Alarm b of stroke with unilateral arm motor deficit within 3 hours of onset (with a 95% confidence interval above 30%) and a specificity of at least 80% using a clinical stroke diagnosis as gold standard.
Stroke is the most common cause of disability in elderly people (over 65years of age) and the third most common cause of death in the world . The World Health Organization estimates that one in six people globally will suffer from stroke in their lifetime. Perioperative stroke is the most unwanted complication for patients, as well as for surgeons and anesthesiologists . The reported risk of perioperative stroke varies with the type of surgery. Its incidence is generally not high (approximate 0.1-1.9%) in non-cardiac, non-neurologic, and non-major surgery However, it may occur in up to 10% of patients undergoing high-risk cardiac or brain surgery . Patients with perioperative stroke are less likely to have a good functional outcome and have an eight-fold higher mortality compared with those without perioperative stroke
On a functional level, performing the actions of daily life requires coordinated activity of the muscles of the upper limbs. The quality of motor recovery and/or technical assistance aimed at compensating for the movement deficit of the paretic upper limb (MSP) determines the possibilities of using the upper limb (MS) in activities of daily life. Interventions in the chronic phase of stroke aim to return home. The integration of the paretic upper limb into daily life activities is a major issue regarding the prognosis of recovery of use of the upper limb. Independence in daily life becomes an ultimate goal to take charge of. Our study focuses on a new technical aid device, standard orthosis type, expanding the range of gripping gloves: the SaeboGlove in everyday environments. These MS orthoses help improve the use and function of the MSP in post-stroke adults as well as their independence and participation in society.
