Active clinical trials for "Stroke"

The goal of this clinical trial is to to determine the effect of movement-based priming using the upper limbs on lower limb neuroplasticity and behaviors in chronic stroke. The main questions we aim to answer are: What are the acute effect of UL-priming on lower limb neuroplasticity and motor behaviors in persons with stroke compared to other priming modalities? What are the time effects of UL-priming on neuroplasticity and motor behavior in individuals with stroke? In this cross over study, participants will be involved in three priming sessions involving - UL-priming using rhythmic, bilateral priming involving the movement of at least one major joint in the upper limbs. AND - Sham priming using auditory stimulation (1 Hz metronome). AND - Stimulation-based priming using anodal transcranial direct current stimulation (tDCS). OR - Lower-limb movement-based priming using aerobic exercise on a treadmill or recumbent stepper. Researchers will compare outcome measures between the different priming sessions.

Evidence suggests that oxytocin has a neuroprotective role on a systemic and cellular level in the context of acute ischemic stroke (AIS). The investigators therefore hypothesize that high levels of circulating oxytocin measured within the first 72 hours after symptom onset are associated with lower mortality and favorable outcome in acute ischemic stroke.

To assess the frequency of signs of pulmonary infection on a chest CT and development of clinical diagnose of poststroke pneumonia，and its effect on functional outcome in patients with acute ischemic stroke.

Up to 84% of patients after stroke are accompanied by dysphagia, of which 53% are oral dysphagia. The oral phase is the initial phase of swallowing activity and the only stage of swallowing that is completely discretionary. Swallowing activity in the oral stage is not only related to the formation and push of food pellets, but also affects the continuity between the transition from spontaneous swallowing to the swallowing reflex.

The primary objective of this study was to evaluate the efficacy and safety of initiation of edaravone dextivel therapy compared with placebo in patients with acute ischaemic stroke (early and late) and to explore the optimal time window for "brain cell protective therapy" of edaravone dexborneol.

Stroke is a leading cause of mortality and disability in Mexico and worldwide. Although current treatment strategies focus on removing oclussion, they do not interrupt the signaling cascade of neuronal damage. Thus, the search for a cerebroprotective agent that can protect the entire brain. Melatonin has been proposed as a potential cerebroprotective agent due to its antioxidant, anti-inflammatory, antiapoptotic, and immunomodulatory effects, which oppose the pathophysiological mechanisms of cerebrovascular disease. Melatonin has the potential to improve stroke outcomes and reduce the risk of disability and mortality, making it a promising therapeutic option for stroke patients. To assess the efficacy of melatonin in patients with acute ischemic CVD, improve clinical outcome, and infarct volume.

The purpose of this quality improvement project was first to monitor usual physical therapy care (types & cardiovascular intensity of interventions and amount of stepping practice provided) and outcomes. Following which educational training and support was provided to treating physical therapists to encourage implementation of evidence-based practices. Specifically, therapists were encouraged to prioritize the practice of walking, particularly at higher cardiovascular intensities during scheduled therapy sessions. Fidelity metrics in the form of chart audits and pedometer-based step counts were utilized to determine compliance with the evidence-based intervention and ultimately investigated for potential effects on patient outcome measures.

AISDTS is a prospective registry study, in which clinical information, examination and imaging data of patients with acute ischemic stroke receiving different treatment strategies were collected, grouped and statistically analyzed, and corresponding clinical prediction models were constructed to explore the role of clinical biological indicators in the occurrence and development of stroke.

According to the definition proposed by the World Health Organization, "stroke is rapidly developing clinical signs of focal (or global) disturbance of cerebral function, with symptoms lasting 24 hours or longer, or leading to death, with no apparent cause other than of vascular origin". Difficulty in walking is present in approximately 80% of stroke survivors. 25% of stroke survivors even after getting rehabilitation have residual gait impairments requiring full assistance after hospital discharge resulting in difficulties in performing basic activities of daily life. Approaches to gait rehabilitation are different based on different models of motor physiology and disease recovery, but most of the approaches are targeting motor impairments during straight walking only as opposed to adaptive walking ability . In order to decrease health care burden effective rehabilitation and prevention is necessary. Multidisciplinary care dedicated for stroke leads to higher independence rates. Conventional gait training regimes including linear parallel bar based gait training and treadmill based gait training protocols do not usually target the angular or rotational component of locomotion. Current study will focus on Unilateral Step Training using a traditional treadmill. This would provide a targeted gait training tool to reduce the risk of fall, improve gait and turning ability and functional activity eventually resulting in greater community participation and involvement in occupational activities. Such an approach could be effective in providing an early targeted and intense training environment similar to task-specific training in contrast to conventional method.

Evaluation of the safety and performance of the BOBBY™ Balloon Guide Catheter (BGC) in patients with an acute ischemic stroke treatment, a sudden reduction or termination of the blood circulation of the brain, caused by a clot. Immediate treatment is needed to restore the blood circulation in the brain, performing a mechanical removal of the clot (thrombectomy). To prevent clot particles migrating in other parts of the brain circulation during the thrombectomy, balloon guiding catheters are inserted. The aim of the study is to evaluate the safety and performance of the balloon guide catheter BOBBY™ by collecting information from patients, treated with a mechanical thrombectomy and the balloon guide catheter (BOBBY™) after acute ischemic stroke
