Active clinical trials for "Stroke"

The current multi-center study aims to evaluate the efficacy and safety of pBFS-guided rTMS Neuromodulation Treatment for the rehabilitation of language functions in ischemic stroke aphasic patients.

To assess the effect of intravenous tenecteplase plus endovascular thrombectomy (EVT) compared to EVT alone on 4.5 to 24 hours after stroke due to basilar artery occlusion.

Intravenous thrombolysis is the first-line therapy in patients with acute ischemic stroke within 4·5 hours of symptom onset, and recombinant tissue plasminogen activator (alteplase) is the preferred thrombolytic agent for this purpose. RhPro-UK is a specific plasminogen activator. rhPro-UK only acts on occlusive thrombus and has little effect on hemostatic thrombus. In addition, rhPro-UK does not form covalent complexes with protease inhibitors in plasma, so the concentrations of rhpro-UK and protease inhibitors in the blood do not decrease compared with alteplase. Therefore, rhPro-UK therapies have a potential advantage of less systemic bleeding in treated subjects. Data from several previous studies suggest that rhPro-UK is efficacious when used to treat patients with acute myocardial infarction. On April 2, 2011, rhPro-UK injection was approved by the National Medical Products Administration to treat acute myocardial infarction. Since then, rhPro-UK has been widely used to treat myocardial infarction in China. Since 2016, a phase 2 clinical trial was carried to explore the dosing of rhPro-UK in patients with acute ischemic stroke, followed by another study with a sample size of 680 patients to initially validate the efficacy and safety of the proposed dose of 35mg. The results of these studies suggested that rhPro-UK was effective, and there were no safety concerns. To further prove the efficacy and safety of rhPro-UK in patients with acute ischemic stroke, investigators conducted this phase 3 study (PROST-2).

Stroke is sudden disruption in central nervous system function due to disturbance of the blood flow circulation in the brain. Cerebrovascular accident (CVA), is the second most leading cause of mortality (5.5 million cases yearly). Its occurrence remains high, with 13.7 million annual incident cases globally. Ischemic strokes are more common with a prevalence ratio of 76-119 per 100,000 per year worldwide ). Stroke is a neurological disease that decrease sensorimotor functions by causing irreversible impairments to the nervous system due to cerebral vascular problems . Patients with balance and activity disturbance are indicated by reduce in body functions. It is very essential for CVA patients to improve balance stability and muscle power for recovery and for normal activities ). Balance is an essential factor for independent living. It is maintained by adjusting COG (Center of Gravity) over the BOS (Base of Support). These adjustments are done through sensational inputs from the vestibular, visual and somatosensory system and are maintained by brain.

The recovery from a stroke is often incomplete. It is the leading cause of acquired permanent disability in the adult population. Persistent functional loss of the hand and arm contributes significantly to disability. However, the current standard of care to treat hand and arm movements are inadequate. There is an urgent need for innovative and effective therapies for recovery of the upper limb after stroke. Growing evidence shows that electrical spinal cord stimulation, combined with activity-dependent rehabilitation, enables voluntary movement of paralyzed muscles in some neurologic disorders, such as spinal cord injury. The investigators hypothesize that spinal networks that lost control after stroke can be activated by non-invasive electrical stimulation of the spinal cord to improve functional recovery. The aims of the study are: to determine the improvements in hand and arm function that result from the combined application of non-invasive spinal stimulation and activity-based rehabilitation. Surface electrodes placed over the skin of the neck will be used for non-invasive electrical stimulation of the spinal cord. Functional task practice will be used for activity-dependent rehabilitation, to evaluate long-lasting benefits to hand and arm function that persist beyond the period of spinal stimulation.

The purpose of this research is to determine if two non-invasive brain stimulation techniques, muscle stimulation of the arm and neuro-stimulation through the tongue, can increase the extent of stroke recovery.

If a subject agrees to participate, the primary investigators will collect some basic information including age, height, and weight. Intake of some general questions regarding health and each subject will complete some tests that measure walking speed, cognition, and balance. During these tests participants will be asked to stand from a chair, walk up & down a staircase, walk over objects in a forward, backward, and sideways directions, walk around objects in forward and backward directions. After completing those tests, participants will be asked to repeat them while doing another task such as counting out loud, naming objects, or passing an object from one hand to another. At the end of the day, a step counter will be attached to each subject's ankle and you asked to wear it when awake for the next 7 days. Investigators expect that the evaluation will last 1 hour. After 7 days, subjects will return the step counter to the researchers and begin the exercise classes. The exercise classes will occur 2 days per week for 8 weeks. In the class participants will be asked to perform gentle exercises and use memory to improve brain functioning. Each class is expected to last 1 hour. At the conclusion of the exercise classes, investigators will again perform the gait, balance and cognitive tasks as we did before each started the class. Once a subject finishes all the exercise classes and testing, investigators will call one every week to see if you have had any falls at home. The calls will go on for 6 months.

Stroke is a major health problem and can cause long-term disability. Among these sequelae, there are balance and mobility disorders, but also a higher rate of anxiety or depression disorders. This impairments impact activity of daily living, and social reintegration. That why the investigators need to explore options for long-term sustainable interventions that which takes into account the patient as a whole. In particular, regular physical activity is recommended, but it must be adaptable to the patient's impairments. Teaching yoga may be an interesting option. Indeed, yoga is a mind-body practice which become increasingly widespread in the world. Recent studies highlight positive effect of yoga for this population. However, accessibility to yoga classes can be limited by many factors: lack of transportation, lack of available health professionals, confinement requirements... Therefore, it seems relevant to evaluate the effectiveness of yoga delivered through tele-rehabilitation. The main objective of this study is to evaluate the effectiveness of a tele-yoga program adapted to stroke survivors to improve their functional balance. The secondary objectives are to evaluate the effectiveness of the adapted tele-yoga program in improving functional mobility, anxiety, depression and reintegration into normal life.

There is still no approved exact treatment for stroke, one of the leading causes of disability. Neurorehabilitation is an important treatment option for stroke patients with anatomical and functional impairments in their interhemispheric connections. However, special techniques with high effectiveness are being investigated to increase the success of general rehabilitation. In this context, scapula-focused stabilization techniques have been used in stroke patients recently. In this randomized controlled study, investigators aimed to examine the effect of scapular stabilization exercises on upper extremity spasticity and motor function in addition to neurorehabilitation in patients with chronic stroke. 22 chronic stroke patients will be included in the study. The patients will be divided into two groups as scapular exercise group and control group using the simple randomization method. Scapular stabilization exercises will be applied in combination with neurorehabilitation to the first group, while only neurorehabilitation will be applied to the control group. A 6-week (30 sessions) neurorehabilitation program will be applied to all groups, specially planned for the patient. Spasticity of the patients participating in the study Modified Ashworth Scale, upper extremity recovery levels Brunnstrom Recovery Stage, upper extremity functions Fugl Meyer Upper Extremity Scale and Wolf Motor Function Test, independence levels Functional Independence Scale , activities of daily living will be evaluated with the Modified Barthel Index and quality of life will be evaluated with the Stroke Specific Quality of Life Scale. The first evaluation of the patients will be made before the treatment, and each patient will be evaluated after the 6-week exercise program. After all data are collected, in-group and intergroup comparisons will be made.

The primary objective is to establish the efficacy of intra-arterial (IA) mechanical thrombectomy (MT) with extracranial proximal carotid artery acute stenting versus non-stenting approaches in patients with acute ischemic stroke (AIS) from intracranial vessel occlusion (IVO) in the anterior circulation and have a proximal carotid occlusive disease (occlusion or severe stenosis) within 24 hours of symptom onset.
