Filter by:In recent years, with the development of medical technology and materials and instruments, flow diverter (FD) has gradually become the most important treatment method for the treatment of intracranial aneurysms (IA). It is a revolutionary treatment method, which has changed the concept of endovascular treatment of IA, and turned the previous endovascular embolization to the reconstruction of the parent artery. At present, FD has been used in more than 250,000 cases worldwide, and the overall 1-year complete occlusion rate of aneurysms can reach 75%-85.5%. However, although the current imaging prognosis of FD is encouraging, the perioperative complications of FD are as high as 12.9%, including ischemic complications, SAH, and parenchymal hemorrhage in 7.3%, 2.0%, and 2.0%, respectively. The postoperative mortality was 1.5%, of which 1.3% were caused by delayed aneurysm rupture, distal parenchymal hemorrhage and PED-related nerve compression symptoms. In addition, an in-stent stenosis of more than 50% within one year has been reported in 10.2 to 15.0% of patients. However, in addition to conventional dual antibody therapy, there is no relevant guideline recommendation or clinical evidence on how to prevent complications after FD implantation in IA patients. Atorvastatin is widely used in the primary and secondary prevention of cardiovascular and cerebrovascular diseases. Its main effect is to improve the incidence of cardiovascular and cerebrovascular events by reducing blood lipids. Although the mechanism of clinical benefit of lipid-lowering by atorvastatin is not completely clear, a large number of clinical evidence has shown that atorvastatin can also reverse atherosclerosis, stabilize plate, reduce inflammation, reverse vascular endothelial dysfunction and reduce microthrombosis. It can reduce the incidence of cardiovascular and cerebrovascular events in patients with coronary heart disease and internal carotid artery stenosis after stent implantation in different degrees. However, there is no high-quality clinical evidence for the use of atorvastatin in intracranial aneurysm stent implantation. Previous retrospective studies have shown that atorvastatin is the only protective factor for in-stent restenosis after flow diverter implantation in intracranial aneurysms. In a retrospective observational study involving 273 patients empirically treated with atorvastatin for unruptured IA in our center, the median follow-up period was 7.6 months. The incidence of cerebrovascular events was 3.27%, and the incidence of more than 50% in-stent stenosis was 8.4%, which was significantly lower than the incidence of related events reported at home and abroad. Therefore, this study planned to conduct a randomized controlled clinical trial to confirm the efficacy and safety of oral atorvastatin in the prevention of cerebrovascular adverse events after stent implantation in patients with unruptured intracranial aneurysms, and to provide objective evidence for the treatment decision of patients with unruptured intracranial aneurysms to prevent cerebrovascular adverse events after flow diverter implantation.
Stroke a devastating neurological condition, causing severe neurological challenges such as balance issues, motor function and cognitive deficits among survivors and can cause disability and death. The use of Virtual Reality and Motor Imagery in rehabilitation of neurologic disorders is on the rise. In stroke patients, VR and MI combination has not been studied. This study aims to investigate the combined effects of Virtual Reality and Motor Imagery Techniques with Routine Physical Therapy in patients with post stroke patients.
The study aims to determine the comparative effects of Modified-Otago and Tai Chi Exercises on Balance and Motor Function in Patients with Stroke.
Use of motor imagery, mirror therapy and motor relearning program in rehabilitation of people with stroke is on rise and these are unique and emerging techniques. Motor imagery is a mental rehearsal through visualization while mirror therapy creates a reflection of non-effected limb by using a mirror. Moreover, motor relearning is task-oriented approach, benefacial for balance and motor funCtion in patients with stroke that emphasizes on relearning.The aim of the study is to determine the comparative effects of motor imagery and mirror therapy versus motor relearning program in addition to routine physical therapy on balance, motor function and activities of daily living in subacute stroke patients.
Stroke is a leading cause of disability. Most stroke survivors face challenge in using their arm and hand to carry out daily task, such as grasping or holding objects. This issue makes it tough for nearly 65% of stroke survivors to return to work and take care of themselves. The cause of their disability is changes in their brain's activity patterns of the motor cortex area. Traditional therapy does not directly alter these brain changes, which makes it less effective. As a way to help stroke survivors, people are looking into ways to train the brain directly. A method they found is motor imagery, which involves mental practicing of a task. Studies suggest that this type of training can potentially alter the brain's patterns, which can be seen through EEG. An EEG shows a fixed pattern during movement, called SMR (sensory motor rhythm). Studies have found that people can learn to control this SMR through mental practice of a task. The SMR changes in a similar way during both movement and motor imagery. Therefore, mental practice of hand tasks can lead to improvement in actual hand movements. It has already been shown that stroke survivors can open their hands more easily after receiving SMR training. Along with that, they also have trouble to hold and release objects. SMR training may be able to address these issues by changing brain patterns. But it is not clear yet if SMR training can improve all three stages of grasping (open, close, release), and to what extent it can enhance overall hand function. This study plans to include 20 adults who have experienced a stroke and have ongoing problems with moving their hands. Half of these participants will take part in a training in which they will learn to control their SMR for three distinct hand tasks (open, close, and release). The first session will be followed by eight training sessions. To guide users toward specific changes in EEG activity, we will provide visual feedback in training. As soon as an appropriate EEG change is made, a hand exoskeleton will help them open and close their hand. The other group of 10 patients will have traditional therapy. They will do 9 sessions of hand exercises. During and after the training, we will test both groups to see how well their hand function improved. The result will help us determine which training method is better for stroke survivors.
The objective of this clinical trial is to determine whether rapid local ischemic postconditioning (RL-IPostC) is effective in preventing brain edema and safe in acute ischemic stroke (AIS) patients treated with mechanical thrombectomy. In this trial, researchers will block antegrade cerebral blood flow temporarily by the way of balloon inflation/deflation in AIS patients immediately after revascularization. It makes the ischemic reperfusion brain tissue have a capacity of adaptation through intermittent blood flow restoration. Researchers will evaluate the protective role and safety of different duration of balloon inflation/deflation. The optimal postconditioning intervention dose will be determined for further confirmative investigation.
The most common problem caused by stroke is motor activity limitation that reduces muscle movement and mobility. But stroke can also lead to sensory and cognitive impairment. Additionally, the ability to independently carry out activities of daily living and participate in social and community life is greatly reduced. Up to 85% of stroke patients experience hemiparesis immediately after stroke, while 55% to 75% of survivors continue to experience reduced quality of life with motor impairments. It requires long-term physical rehabilitation to achieve functional recovery in the upper extremity, maximum independence and the highest possible quality of life. Different methods can be used to achieve these results, but there is no clear evidence yet as to which treatment method gives the best results. Scientific evidence shows that a multifactorial approach and high-intensity treatment accelerates the motor recovery of the upper extremities in stroke rehabilitation. Passive and active upper extremity movements appear to increase motor recovery due to their effects on somatosensory input, motor planning, soft tissue properties and spasticity. In recent years, robotic devices have emerged that have been proven to improve the motor performance of the upper extremity in chronic stroke patients. There are also studies showing that robotic device-assisted upper extremity therapy can contribute to the development of sensorimotor skills in plegic patients. However, in the current literature, there is still a need for randomized controlled studies in this field. The aim of this study is to investigate the effects of robot-assisted therapy on upper extremity functions and daily living activities in the rehabilitation of chronic stroke patients. After the demographic data of the cases in both groups are obtained, evaluations will be made before the study. Then, the study group will receive conventional physiotherapy in a single session of 45 minutes a day, 3 days a week for 4 weeks, and in addition robot-assisted therapy with the ReoGo Upper Extremity Exoskeleton Robot in a single session of 60 minutes a day, 5 days a week for 4 weeks. The control group will receive only conventional physiotherapy in a single session of 45 minutes a day, 3 days a week for 4 weeks. The initial evaluations will be repeated after the end of the treatment period.
Minor strokes (few acute neurological symptoms ; NIHSS score <5), represent almost 65% of cerebrovascular ischemic events. The increasing incidence of stroke in people under 65, together with advances in diagnostic and revascularization techniques, mean that post-stroke life expectancy is now in the order of decades. Most patients with minor stroke are rapidly discharged from hospital, with follow-up focused on secondary prevention and they are offered little or no rehabilitation. However, up to 70% of patients with minor stroke experience difficulties resuming their social or professional activities, which can lead to social and economic disruption (delayed/compromised return to work) and an increased risk of depression. While some care recommendations exist for this population, in France there is no consensus nor identified care pathway for follow-up assessment or management of these patients. Furthermore, existing services are unevenly distributed across the country, and research into the effectiveness of rehabilitation is still scarce, leading to uncertainty as to which interventions should be prioritized to decrease difficulties related to cognitive impairment. Since there are currently no rehabilitation proposals in France for patients with mild cognitive impairment after mild stroke, in this trial the investigaror will investigate the effectiveness of two six-week telerehabilitation programs each consisting of a weekly session supervised by a therapist and a self-rehabilitation session. The aim of this multicenter randomized controlled trial is the evaluate the relevance and feasibility of early identification of patients eligible for a cognition-focused management proposal and the efficacy of two telecare programs, (a) psychoeducation and (b) computerized cognitive rehabilitation.
Ankle braces are commonly prescribed to individuals who have suffered a stroke to help their ankle joints work properly, which allows these individuals to walk better. Currently, there are no standardized guidelines to follow when choosing which brace is best for an individual. Prior work has shown that customizing the level of assistance that these braces provide based on each individual's level of ankle impairment improves the individuals' walking function more than their current brace. The next important step is to fine-tune the customization and work to develop a set of guidelines that can be used by clinicians to help them prescribe the right brace for each patient's needs. The purpose of this study is to test different levels of assistance provided by the brace to determine the optimal customization method. Additionally, this study aims to begin to create a guide to help clinicians choose the best brace for each individuals' needs. To accomplish this goal, individuals will walk with a brace under five different assistance level conditions. The individual's walking function, performance on clinical measures, and response to questionnaires will be examined to determine both the optimal brace for each individual and hopefully identify clinical tools that can be used to guide prescription of the brace. This study is a major step towards developing effective, standardized prescription guidelines that optimize walking of individuals post-stroke.
Upper-extremity impairment after stroke remains a major therapeutic challenge and a target of neuromodulation treatment efforts.In this open-label, randomized phase I trial, we applied deep brain stimulation to the cerebellar dentate nucleus combined with bilateral or unilateral stimulation. We hypothesized that bilateral stimulation was superior to unilateral stimulation as the motor rehabilitation after stroke benefits from both side of cerebellum.
